Guru, how do I develop R&F levels for: Outdoor against the mass market and specific demograhic such as individual with $3Million in assets. spot market print such as business journals, lifestyle mags etc, where there is no syndicated research such as MRI. Local Cable against a high affluent audience

The Media Guru Answers(Sunday, December 03, 2000 ):
It is not clear whether your issue is determining the portion of the audience of each medium which falls within your target or whether the audience accumulation pattern among your target is the problem.

Syndicated print and product usage research, particularly The Mendelsohn Media Research Affluent Study, analyze audiences od many media specifically aimed at affluent subsegments, although "assets over $3million" may be too narrow for syndicated research to have evaluated.

Outdoor companies are usually prepared to run R&F analyses against a wide range of demographics. Commercial media software, such as ADplus from our susiter company Telmar can produce R&F analyses from minimal target data input.

A client has asked for information pertaining to the level of advertising required to increase awareness and positively affect the perception of their company on an on-going basis. Is there a source for information regarding required grp levels for radio and television to maximize awareness. Our client is based in Phoenix, Arizona, with an interest in statewide coverage?

The Media Guru Answers(Wednesday, November 29, 2000 ):
Awareness relates most to the reach and frequency of a plan. You must reach more people more often to increase awareness. You must reach more people than are currently aware.

Where do I find information on weekly GRP levels to use in radio for a service that is constant throughout the year, with no seasonality?

The Media Guru Answers(Monday, November 06, 2000 ):
  • Determine GRP from desired reach and or frequency
  • Determine desired reach / frequency from awareness or sales goals; you can only sell to people who are aware of the service.

Can you clarify the difference between a pulsing strategy and a burst stratgey? And are either one contradictory to or in support of the recency theory?

The Media Guru Answers(Monday, October 30, 2000 ):
As the Guru sees it, "pulsing" refers to alternating, short and equal flights of advertising and periods of hitaus. Burst refers to sporadic higher levels, with no particular flight vs hiatus rhtym, nor equality of levels.

Pulsing is clearly contrary to recency. Bursts, if they are sporadic higher levels within lower level, continuous activity are not totally at odds with recency.

We have a client who wants an internet media plan, but will be using a buying service to place the buys. They have a monthly budget of $40k. Do you have any suggestions on how to price a media plan when not being involved on receiving agency discounts from the buys? Also, are there any average commission levels agencies use when purchasing internet buys? Thanks for any help you can offer.

The Media Guru Answers(Tuesday, October 17, 2000 ):
The starting point, of course, is that the whole agency process is worth 15% of gross.

Many cases allocate 5% to media and 10% to the rest of the agency thinking work; creative, account service, etc.

In the internet, as in magazines, "planning" is very specific, down to number of uses per title, and on-line even more so, with pages, sections, units all part of the plan. This leaves the buying service with not much more to do than order processing. All this says planning might be worth 3 or 4% and buying 1 or 2%. If the buying service is pre-negotiating and providing you with prices on all the placement possibilites your plan will consider, then that tilts toward the 3/2 split. If it's purely order taking to your specifications, then 4/1.

Dear Media Guru, Off the top of your head, what would you say are consumer "target groups" that are the most difficult to reach through television advertising. In other words, what are "target groups" that marketers of consumer packaged goods companies would like to more effectively reach?

The Media Guru Answers(Thursday, September 28, 2000 ):
"Off the top of the Guru's head" the most difficult targets to reach are not neccessarily the targets for consumer package goods. The toughest ones are probably young men and male teens.

Thinking more broadly, there is the Hispanic market, which is highly desirable to package goods marketers, and not reached effectively by general market TV nor at high reach levels in Spanish language TV.

What are the benefits of Spot TV versus print for a 3 month launch campaign?

The Media Guru Answers(Saturday, September 09, 2000 ):
TV is a more active, impactful medium than newspaper. There is a greater range of flexibility in schedule, reach and frequency, especially in achieving quick, up-front high levels. 95% reach at 20+ frequency in week 1 is possible in TV, with nothing close possible in local print. But budget will be a key issue.

Kaun Banega Crorepati is the Indian version of the game show Who Wants to be a Millionaire. It is a runaway success in India just as it has been elsewhere. I have three questions for the Media Guru: 1. What has the experience of Who Wants to be... been in markets like the US and UK in terms of viewer fatigue? Did fatigue set in after 30 or 60 or 90 episodes...did the network have to refresh programme format or add new elements to keep interest levels high? 2. How has it impacted the performance of other programmes on the same channel/network airing the game show? did viewership of other programmes on the network too go up? 3.

The Media Guru Answers(Saturday, September 09, 2000 ):
In the U.S., after a year, running multiple episodes per week, "Millionaire" is still often the #1, #2 and #3 rated program of the week, with no significant changes.

The program has helped its network and been used as a deadly weapon competitively.

The NY Times Sunday Magazine recently published an article comparing the imitators around the world, including Kaun Banega Crorepati.

M.G. - please advise how to perform an analysis of TV HUT levels using MRI syndicated research tools? We want to evaluate HUT levels in our market in order to confirm that our daypart mix will be effective (to influence a purchasing action when our target is home using television). Thank you.

The Media Guru Answers(Friday, September 01, 2000 ):
does not compute.You really can't and shouldn't anyway.

"HUT" is Homes Using Televison. That is, the percentage of all Television-owning homes which have the set turned on at a point in time.

MRI does not report data about households and does not report point-in-time data about TV, but rather data which might be interpreted as cumes.

The analysis you propose, that judging effectiveness based on the portion of the audience which is using television in the dayparts which you purchase, is off the mark. A simple reach evaluation is much more sensible. You can reach 95% of the people in prime time, which has the highest HUT level or 95% of the people with the same GRPs dispersed though several, more efficient dayparts. Or you might reach more perple in dayparts with a lower HUT but efficient enough to afford lots more weight.

Use tools intended for TV, such as Nielsen, and reach ansd frquency tools like Telmar's

Hi Guru, I have a client looking to open a new office somewhere in the US and am conducting research to find the best possible area to set up shop. We do not have MRI and only have 10 Scarborough markets in house. I have found USAdata.com can pull across Scarborough's 64 markets for certain qualifiers we are looking for but am wondering if you know of anywhere else I could obtain this information, specifically HHI, Housing Prices, and educational levels across the largest markets in the US (for free would be a plus)?

The Media Guru Answers(Friday, September 01, 2000 ):
For free, the Census offers some of that. Other housing data m,ight be found through FedStats. None of that will be on a DMA basis, though. For a little money, Standard Rate and Data Service (SRDS) Lifestyles Analyst or Sales and Marketing Management Magazines annual market analysis.

Media Guru(s), Hopefully will not humiliate myself with this question: When planning a trade campaign (target is Neurologists,and GPs) how do I determine the time frame for reach/frequency? I have set effective freq. at 4. Is this over a 4 week period? Can it be over a quarter? I cannot achieve a 4 week freq. of 4 against the Neurologists, but I can against the GPs. Does this mean that using trade print to reach the neurologists is not effective/appropriate? How do I rationalize a 4 week r/f delivery time frame for the one target group and a quarterly time frame for the other? Or am I totally missing the mark in both cases??? R.

The Media Guru Answers(Monday, August 28, 2000 ):
The "standard" period for evaluating reach and frequency is 4 weeks or a month, if all print.

When considering effective frequency, some thinkers believe that every exposure after the crtical number is achieved is delivered effectively. This is a cornerstone of the "Recency" theory. So, you can think abouit your effective levels on a rolling, cumulative basis, and merely state that effectivene reach is being delivered to GPs as of "X" point in time and against neurologists as of "Y" point in time.

Dear Guru, What levels of commission are paid to third party agencies selling advertising inventory on behalf of websites?

The Media Guru Answers(Friday, August 11, 2000 ):
The Guru has seen figures from 30 to 85%. Naturally, the biggest sites get better deals.


Wednesday, August 02, 2000 #3666
Ref. question 3663 Thanx for answering my question. I buy slots with high eff. index when my objective is to accumulate GRP's and drill my message into my consumers mind. This is the secondary stage where after creating the initial reach i focus on accumulating greatest total number of impressions (Funnel Treatment). As for the decay factor it reflects the decrease in the recall leval when advertising is reduced or stoped. I normally use 10% decay level in IMphase(IM horizontal planning technologies) The question that i want to ask you is what is the better way of flighting. There is a 70's 3+ eff frequency model by Prof. MacDonald which says that brusting is a better flighting patteren.On the other hand there is more recent Recency concept championed by Prof. JP Jones of Syracuse university of NY which says that as far as FMCG goods are concerned people are in the market every week and infect only needs one OTS to stimulate purchase.Please comment MY second question is how do you calculate Eff Frequency. Normally i use Eff frequency model where i calculate the eff frequency by applying judgement and common sence in a disciplined manner using Marketing, Advertising and competitive factors Thanx Sarwar Khan Media Manager R-Lintas Lahore,Pakistan

The Media Guru Answers(Sunday, August 06, 2000 ):
1. In regard to 3+ effective frequency versus recency, the Guru tends to favor recency for "Fast Moving Consumer Goods." Recency is not really a contrast to the 3+ frequency theory, but an extension. As championed by Erwin Ephron, a core concept of recency is that once the third exposure is delivered, all additional exposures are at 3+.

2. Once again, there seems to be a semantic issue when you say "calculate" effective frequency. If you mean setting the frequency level to be considered effective, then your "judgment and common sence in a disciplined manner using Marketing, Advertising and competitive factors are the right approach, and the Ostrow Model will be helpful.

If instead, you mean to calculate the effective frequency delivered by your schedule, this has absolutely nothing to do with the subjective factors you have listed. A reach model determines how many persons are exposed to each discrete number of ad units in the schedule. That is if your reach is 75%, that means, explicitly, that 75% of the target has experienced one or more ad exposures. Within this, perhaps 70% of the target has been exposed to 2 or more, 66% to 3 or more, etc, up to the full number of units in the schedule. Reach models allow for expressing all of these levels. "Effective reach" mean those reached at least the minimum number of times established as effective, most typically 3.

hi where can i find researches or information about drugs advertising? which media have the best influence on patients? t.v? press? Radio? which reach & frequency levels are recommended ? thanks

The Media Guru Answers(Monday, July 10, 2000 ):
The answers will vary depending on typical media planning / marketing issues.
  • Who is the target?
  • What is the competitive situation?
  • What are the legal restrictions
For example, in the U.S., there is one set of rules that applies when you are marketing prescription drugs and another set for "over the counter" pharmaceuticals.

For prescription drugs, you can mention a drug name without discussing the problems it treats or its results, or you can mention a problem to treat without mentioning a drug name. In these cases there are fewer rules to observe. When you mention a drug along with its disease or results, you must also provide the "patient information" (PI) which is all the side effects warnings, counterindications, etc. This typically means broadcast advertising must be accompanied by print to carry the PI. Or that print must devote a portion of space to this detailed information.

What are the average commission levels charged from web publishers by ad networks like DoubleClick, Flycast, 24/7 Media etc.?

The Media Guru Answers(Monday, July 03, 2000 ):
The Guru has seen commission levels from 15% to 85%. These larger reps, who handles larger sites, are probably at the lower end of the scale, 20% or so.

Media Guru, I'd like to clarify my question from last week about national media vs. spot media planning. Based on the marketing and communication goals of our client, we have determined that network television is a necessary part of our media mix. We are in the process of aquiring reach/frequency software for national media, but don't currently have it so I can't do a run to determine TRP levels that will generate effective levels of reach/frequency. So, in order to get a feel of what other national advertisers planned, I looked at other plans that contained network television. In looking at those plans I noticed that the TRP levels are significantly lower than spot television plans. Have you noticed that same descrepancy in media plans that you are familiar with? If so, why?

The Media Guru Answers(Tuesday, May 30, 2000 ):
You must be comparing all-TV plans where one is all spot and the other is all network for these comparisons to make sense, in the first place. If there are other media involved, naturally that will affect TV levels.

In national plans containing both media forms, the network will be mostly low-readh daytime and high-priced prime. So there are reasons to limit investment in each. Spot ususally is concentrated in fringe times, which offer better reach potential than day and better efficiency than prime, so that is one reason for higher spot levels.

In other plan where there is network as well as spot, spot may be used to give extra weight to markets with greater sales or greater sales potential or to fill in market that are underdeliverd by network versus national averages. In any of these cases, spot is typically used at higher levels, but in a short lis of markets.

There is nothing inherent in spot versus network to make spot levels higher than network when either one is the sole medium.


Friday, May 26, 2000 #3500
Guru, I have had a lot of planning experience for spot television and local cable television and am now being asked to plan network television, network cable television and syndicated television. I've noticed after looking at several example plans that network GRPs are often lower than spot GRPs ... Why is that and what are effective GRP levels for network media? Please help.

The Media Guru Answers(Monday, May 29, 2000 ):
The Guru would surmise that in spot, you have seen more promotional or retail-oriented schedules, where noise level is the basis. In network plans, more sophisticated assessments of communications goals may have been made, focused on reach and frequency.

The concept of "planning spot tv" or "planning network TV" is also puzzling. The media choice is the result of planning, not the going-in assignment. Are you part of the buying process moving to network tv where multimedia plans may have been assembled by others, prior to your involvement with a single element?

Question: Would you please advise how audience accumulation builds over time? For: (A) Weekly Consumer Magazine (B) Monthly Consumer Magazine (C) Business Publications (D) Out of Home Media. I suppose that based upon the type of media -- daily newspaper versus monthly magazine, that audience accumulation will vary quite differently. But from the standpoint of audience accumulation over the course of time from Week 1 to Week 2 to Week 3, etc., because of duplication, the accumulation figure will decrease --- with reach maxing out. Could you please provide a run down by media type (A, B, C, D) as to how accumulation figures build over time?

The Media Guru Answers(Sunday, May 14, 2000 ):
To really evaluate this you need the specific respondent-level data from individual media, such as that provided by MRI or Simmons.

Generally, in any print medium, the audience builds quickly at first, within the medium's cycle. For instance, a weekly builds the vast majority of its audience within the week following issue, and virtually all of its reach within 3 weeks. A monthly has a similar shape to its "reach curve" over time, but the 3 week time line extends to perhaps 2 months. Business publications would probably compare similarly for weekly versus monthly.

Out-of-home media are quite a different story. Since they are not media with content, and are incicentally encountered in life as opposed to the audeince seeking it out, there is no aging content to affect readership. Because out-of-home, at least in the case of outdoor posters, is bought at enormous GRP levels ( usually 25 to 100 GRP per day), reach accumulates very quickly, reaching 85 to 95% of an audience in the first month. The medium itself does not get measured, the campaign does.


Tuesday, May 02, 2000 #3439
Regarding effective reach and effective frequency, are there general accepted boundaries of these measurements as they relate to radio and television? How do you compute effective reach and frequency?

The Media Guru Answers(Thursday, May 04, 2000 ):
The Guru has seen effective frequencies from 2 to 9 used in plans. Most often, 3 is the "bogie" but 4 and 5 are not uncommon.

In the Guru's opinion, the effective levels make sense when applied to a majority of the target, that is, 50%+.

As far as computing effective R&F, the capability is typically built into reach and frequency calculators. As part of calculating reach, the frequency distribution is calculated. This is a calculation of the discreet number of persons reached by each ad in the schedule. Thus one can compile the number (or %) of target persons reached "at least" the set number of times.


Monday, May 01, 2000 #3434
I am trying to determine how best to manually calculate reach and frequency for Out of Home Media. Would you be able to help and provide me with reach curves and turnover ratios for OOH media. Thank you.

The Media Guru Answers(Tuesday, May 02, 2000 ):
Out-of-home (outdoor poster media) is usually bought in #25, #50 or #100 "showings." These are based on daily effective circulation, or traffic, equal to 25, 50 or 100 GRP per day, respectively.

Within the state of the art, in rough terms, these levels usually mean 4-week reach and frequencies of approximately

  • 80 / 8.8 / 700
  • 87 / 16.1 / 1400 and
  • 92 / 30.4 / 2800.

As should be apparent, there is not much room for fine tuning, nor much reason for considering other GRP levels.


Wednesday, April 19, 2000 #3410
What is your opinion on using out-of-home (30-sheets or bulletins) as a stand-alone medium for a brand-building campaign? On a related note, are there any "rules" for adjusting different types of media for their "impact" versus other media (e.g., impact of an all-newspaper campaign versus an all television campaign given the same TRP levels and the same "likelihood of use" by the target market)?

The Media Guru Answers(Friday, April 21, 2000 ):
The Guru has seen impact adjusments across media based on recall, on attentiveness and on an advertiser's proprietary research, but no general rules-of-thumb.

Unfortunately, such adjustments are too often based on one unit of the advertising, such as a TV spot versus a radio spot, and don't take into account the crucial difference in number of spots or GRPs per dollar.

As for brand-building in outdoor, there are two principal considerations in the Guru's view:

  • Definition of "brand building:" The term, one of those nebulous buzz-words which seems to mean whatever the speaker wishes, implies, to the Guru, the creation of a brand image and positioning from a low-awarness start.
  • Limited message: How much can a brand be "built" by the few words and large graphic allowable in out-of-home media?
  • Yet, the Guru is very favorably inclined to taking advantage of the enormous reach and frequency possible via out-of-home

In short, the Guru's gut feeling is that outdoor can contribute greatly to brand building, but that the process needs at least one longer-form medium.

Dear Media Guru: Where can I find the Media Spending/Rating levels by Daypart(TV) and Magzines(Print) for the BP Amoco Account over the past two years. (This is for United States only.) Is there any site that would show their recent commercials as well? I am researching a media position for this account and would like to understand their overall Marketing and Media Strategy to see if it would be a productive match.

Please explain the use of BDI/ CDI and MOI in relation to the media strategy, whether media activity should be aggresive, maintenance etc.

The Media Guru Answers(Friday, March 31, 2000 ):
Indices like these, (though "MOI" is not familiar, possibly Market Opportunity Index?) are used to compare geographic markets media weight/spending levels. Typically, one, geographically flexible, element of the media plan, such as spot TV is adjusted up or down in DMAs or regions, to give each area the appropriate activity based on relative sales, or sales potential index. It's not exactly a question of "aggressive" versus "maintenance."

Is there any type of resource on the Internet where I can go and side-by-side compare third party ad servers as well as companies like Nielsen-Net Ratings and AdRelevance? Just like CNET does for comparing hardware?

The Media Guru Answers(Friday, March 24, 2000 ):
When CNet compares hardware, there is a potential of hundreds of thousands or millions of interested buyers. WWW audience tools are likely to be bought only by the biggest sites.

However, at these levels, the individual vendors may be expected to provide detailed comparisons of their offereings versus the competition's. But be sure to get the comparison from more than one.

Guru, any thoughts on how to estimate % trial as a result of advertising (effective reach 50% at 3.6+ effective freq. print plan, only medium).The brand has done little advertising,has limited awareness(8% unaided) in a moderately competitive category(indigestion remedies). I have factored the target group pop.(W55+) by the incidence of the condition, then further adjusted by % likely to treat the condition, to arrive at a "Total Potential Prospects". At this point I would like to estimate the % that can be persuaded to trial, to determine estimated prospects and potential sales, but I have no historical advertising or client data on which to base the expected return. Would you base return on current awareness levels, or current SOM? No growth expected in the category,assume trial at the expense of the competition. I am attempting to devise a systematic method of determining ideal effective reach,linked to sales objectives, as I am not content to leave it at "maximum affordable at effective freq. level" Sorry for all the blather, but your thoughts and wisdom would be much appreciated. R.

The Media Guru Answers(Saturday, March 04, 2000 ):
What you seem to need is a persuasiveness measure: what is the percent who would try the product (purchase intent) with and without advertising exposre? Many marketers have done such research and, if available, it can be factored against your "total potential prospects."

Dear Guru: Do you have an information on 'buget cutting'. I have a client that plans to cut l/2 of his original budget. What happens when infufficient funds are appropriated for media use (we have 5 new products to launch). Is it the planners job to tell the client that this remaining budget in not adequate? Any suggestions? Many thanks, as always.

The Media Guru Answers(Monday, February 07, 2000 ):
Yes, sometimes low levels of spending will be completely inadequate to accomplish even a proportionate piece of the goals.

It is certainly a planner's responsibiltiy to advise the appropriate parties of the problem and to recommend alternatives in the form of new goals for which the budget is adequate.

These might include:

  • Reducing the geographic coverage
  • Reducing the advertising activity period, especially if early success could generate new funds
  • Reducing the number of products to be supported at any point in time.

Thursday, January 27, 2000 #3167
Hi Guru, I posed a question to you earlier today that might require some clarification. I'm speaking specifically about Internet advertising and am really looking for some guidelines in what are generally considered to be optimal levels for reach and frequency in a campaign. That is to say, how many times does a user generally need to see a banner before its value starts to diminish. Secondly, how many banners should one consider purchasing -- again as a general rule -- in order to maximize the flight's impact. Another way of looking at might be to say, if one were to buy one million impressions, what is the likely number of people who will have been impacted? I realize there is a wide range, based on the narrowness or broad-based appeal of the sites, but is there a general range that can be modeled from?

The Media Guru Answers(Thursday, January 27, 2000 ):
This is a very interesting question.
  • The irony of the concept of effective frequency on the web is that effectiveness, measured as click-thru, has been shown to drop through the first three exposures to a banner and then flatten. (see DoubleClick: "Banner Burnout")
  • The Guru is also quite leery of "modeled" web R&F that does not take into account specific sites used. Often, one advertiser gets more reach from only one-sixth as many impressions as another advertiser. For example Nielsen//Netratings posts their measured "Top ten advertisers of the month" with each one's impressions and reach. At this writing, December 1999 is posted. Amazon.com (#3) ran 620 million impressions and got 54% reach while TRUSTe (#1) ran 2.1 Billion impressions for only 37% reach. Even Barnes & Noble (#7) with 276 million built 38% reach

Another question : How is the recomendated efecttive frequency for a launching campaing, for maintennance, for a promotion. The efective frequency is relative, but the experience and the knowledge of the people there somilars in many countries. Please help me

The Media Guru Answers(Sunday, January 23, 2000 ):
Effective frequency always seems to start from the basic 3+ times which comes out of the original research. Then the next question is what reach level to set at this effective frequency benchmark.

Some planners set various other efeective frequency goals depending upon various marketing factors (see the Ostrow model).

Most simply, introductions and promotions would suggest higher effective frequencies while maintenance can use minimal levels.

What is media planning, and how does it differ from media buying?

The Media Guru Answers(Friday, January 21, 2000 ):
To put it very simply:

Media planning is the process of determining which media best meet the advertiser's objectives and strategies, as well as which geography merits what share of budget. levels of spending and weight by medium and daypart or vehicle are also a planning responsibilty.

When these determinations have been made, Media buying identifies best locations of individual advertisements and negotiates their price.

What is the minimun number of GRP's a radio schedule should have to reach A35-64? I have planned a minimun of 50 GRP's for various markets, but I do not know if this is too little, or too much.

The Media Guru Answers(Wednesday, January 19, 2000 ):
The only generally accepted "minimum" in radio advertising is 12 spots per week per station. But GRP must be considered as well in judging communications value.

50 GRPs is almost too small a total schedule to bother with. Most advertisers, pulling a number out of the air would probably start with 100 GRP per week in a campaign if radio is the only medium being used. A total campaign of 50 GRP should reach about 20-22% of the target, at a low level of average frequency: about 2.3. This would not be expected to generate much consumer response.

4 weeks at 100 GRP/week will get about to 50% target reach at an average frequency of 8x.

Certainly budget is a constraint, but effective levels in fewer markets is better than wasting money in a longer market list.

I am working on a preliminary recommendation--a branding awarness campaign for a bank that currently does product advertising but no image advertising. Thre are three levels of spending that will be discussed. The question that I have is what freqency levels should be achieved to have not only a increase in awareness, but also influence the target to switch banks. It is a competitive banking market. What do you think of these reach and freq levels based on 4 weeks of advertising?? The media mix for the first 2 includes TV and Outdoor/Transit and the last Outdoor/Transit. There would be 1 TV commercial, 2 messages for Outdoor and 2 messages for transit. So, I am not concerned that much about wearout as having adequate effective frequency levels. Schedule #1 91% reach/14.6x; Schedule #2 is 90%/11x ; #3 is 79%/9.9x please let me know what you think of these frequency levels. Thanks

The Media Guru Answers(Monday, January 17, 2000 ):
When you evaluate media schedules which include out-of-home media, considerations of "effective" frequency go out the window. The nature of these media is to amass enormous levels of frequency behind simple, undetailed messages. Statistically, any of these schedules would have plenty of effective frequency, although you haven't mentioned the effective frequency in your details. The most effective schedule would be one of the first two, and the best of those is the one with the higher reach and frequency. Apparently the second costs less than the first.

Dear Guru Please can you tell me how I know when x% reach is enough? From going through the archives it seems as if your answer will be "that this is a judgement call" but surely there must be something more scientific than that?

The Media Guru Answers(Wednesday, January 05, 2000 ):
Yes, the Guru has often answered such questions with that phrase, but went on to list the considerations to review in making the judgement.

You need to build toward a reach goal, not pull it out of your hat. There is no piece of science that makes one specific reach number correct as an abstraction.

If some level of ad awareness is your real goal, the reach must be at least as high as the awareness level desired: people must see an ad before they can become aware of it. If you believe that it takes three exposures to a campaign before the consumer is consciously aware of the campaign then the awarenes level becomes the 3+ reach level, and a total (1+) reach level may be inferred from that.

If you follow recency theory, you will evaluate the continuous levels of reach delivery affordable in possible media options.

So "enough" is not simply "enough," it must be enough to accomplish a specifed goal of awareness, sales, image change, etc.

Can you help me out in the following areas: 1. How can an online agency offer an advertiser pre campaign creative testing of ad banners? What are the variables involved and can you suggest links to sites that do offer such solutions? 2. Can you provide an online plan for any hypothetical advertiser? What is the step by step approach taken? I know one will have to proceed looking at marketing objectives, setting impression levels and then buying impressions based on the campaign objective and target audience. Do you have a ready framework for a full online plan that you could share with us?

The Media Guru Answers(Saturday, January 01, 2000 ):
1. There are companies which do such testing, including IPSOS. C.A.S.I.E. (The Coalition for Advertising Supported Interactive Entertainment) will have a list of such vendors.

2.There are no standards for how an on-line plan should look, other than those for any media plan. Because the focus will be on selecting specific sites, the overall style will probably resemble a magazine plan more than any other specific type. One plan might focus on advertisng envorinment more than another which is more aimed at raw impresions, and both may differ greatly from a third based on click-rates or revenue generation. Analysis might focus on cpm or reach or availability of relevant pages or keywords. Creativity is more the rule than following a format.

Guru: I'm trying to plan an online media buy for branding purposes and having a hard time devising a formula for adequate impressions levels. I think % reach is a better way to go, but what's the optimal % reach for online branding on a website (high enough frequency without waste)? Thanks!

The Media Guru Answers(Wednesday, November 03, 1999 ):
It is very early in the scheme of internet reach models to imagine that there are standardized formulas.

You are correct to think that "branding," which means different things to different people, but seems to be about awareness in most definitions, depends upon reach.

But reach in relation to internet impressions is a curious thing. As in all media, it depends upon duplication between one day's visitors and the next plus duplication between one site's visitors and another site's.

When reach formulas are created, they begin from examination of the actual reach and frequency in real advertisers' schedules.

In this connection, it is instructive to visit the "Top 10 Advertisers of the Month" page at Nielsen//Netratings, a web audience research firm. In the month of September, 1999, the #1 advertiser, in terms of impressions, was TRUSTe, with 945 million immpressions and 25% reach among persons with internet access. But Amazon.com, the advertiser with the highest reach, at 44%, had less than one-third as many impressions, 273 million. Other advertisers with as few as 103 million impressions surpassed TRUSTe's reach.

The bottom line is that

  • Clearly, there is not a lot of consumer reach possible on the web, if the top advertisers' perform like this.
  • Impressions-to-reach models are going to be complicated to build.
  • We probably need a new definition of "branding" for on-line purposes.

We work with a client who is a franchise of a larger hospitality company. In previous years, their plans have consisted of heavy spot TV schedules in their various markets. In 2000, they are making a large jump into network, leaving minimal dollars for supplemental spot buys. They are not achieving total TRP levels of previous years, and want to know the trade off of heavy spot vs. lighter, higher quality network. Besides anecdotal info, I'm at a loss. Please help! Thanks in advance.

The Media Guru Answers(Friday, October 01, 1999 ):
The key consideration is how close to national your client is. How much waste are you buying when you use national media versus media falling only within target areas?

You are using an assumption of "quality" here that the Guru couldn't justify. What is your definition of quality, rating size? First run versus rerun? The Guru doesn't believe those factors contribute much to sales. In either case, whether in spot or in national, you can chose your programs, air in prime-time, first run programs, etc.

If there are large parts of the country where advertising weight is waste, and if you must short-change good prospects in order to be national, what's the benefit? If your coverage area had been close enough national, you would have found economies of scale in moving from spot to network.

Dear Guru, I am writing to you from the Middle East. First of all I am very excited to discover the AMIC site. I have recently been exposed to various documentation on the recency theory. Alongwith the documentation I have seen something called reach curves. The reach curves I have seen are typically for 1+, 2+, and 3+ levels for all adults and all women audiences. I understand it is an easy way to translate Effective Reach goals into GRP goals e.g. X GRPs will get you Y% 3+ reach against the target. It also clearly depicts the point of diminishing return. I am eager to know how I can develop reach curves for my market. Can this be done by us in the media department or do we need to approach some company which specializes in this area. What sort of data is required? Just to give you a background, we are not a metered market. TV audience measurement is conducted thrice a year using face-to-face interviews with a representative sample. Viewership is typically available by 15 minute time segments for all channels across various demos. Thanks in advance.

The Media Guru Answers(Tuesday, September 14, 1999 ):
Reach curves have been in use since long before computers were used in media departments and long before metered measurement.

Curves are created by using the reach of actual schedules. For example, in the U.S., Nielsen would report the actual reach of specific brands' schedules, based on examining the net unduplicated viewers in their reasearch data who viewed the program schedules used by the brand's commercials.

Once you have several schedules ( 8 or so will do) with actual reaches and frequencies for various GRP levels, you can use the regression analysis data function in a spreadsheet, like MS Excel or Lotus 1-2-3, to calculate a formula which describes the curve. This formula can literally draw the curve on a graph, or let you build a table of GRP / Reach pairs. By the way, it is the frequency and GRPs which are used in building this regression, because while reach is a curve, frequency is a straight line.

Let me elaborate further on the question posed by Ajay (Question sent from India , which was answered on 8d August). In India, the data collection and hence reporting of the peoplemeter data is on a weekly basis, unlike the daily collection and reporting in most other markets. Since we follow a weekly collection, the sample is determined for each of the seven days. (after rejecting viewing which does not satisfy the threshold levels of various criteria that the viewing data is supposed to fulfill). As is obvious, this effective sample could be different across the days. Hence, we actually could end up having 7 different samples for each of the seven days. The question now arises as to which of these seven figures to use for projection to the universe. This is the part where the difference in the reach and rating calculations occur. A rating figure is calculated based on the sample for each day. Hence , on Monday, if the effective sample is 95, then this 95 is projected to the universe figures. On Tuesday, the effective sample could be 96 - then this 96 is projected to the universe figures. And so on. Hence the actual weights attached to the sample could vary, though the universe figures remain the same. Once the sample figures have been projected, the ratings are calculated. These rating figures can then be averaged across days , if desired, since a rating figure can be averaged across time periods. On the other hand, a reach figure cannot be averaged. Hence, if the sample is different across each of the days, the dilemma is as to which of the effective sample to use for the projection purpose. Hence they designate one day as REFERENCE DAY. The effective sample on the reference day is the one which is used for projection purposes and hence for all further calculations for reach figures. The reference day changes depending on the period chosen. In India, the research agency has fixed the reference day to be the last day of the period chosen. So, if I vary my period of analysis, the reference day changes and hence my reach figures change. This is where the confusion occurs ! Since a rating calculation does not have a reference day, the ratings don't change, irrespective of the period chosen. So please let us know if this is the norm followed across countries ? Is the concept of reference day valid ? How do other countries deal with this ?

The Media Guru Answers(Thursday, September 02, 1999 ):
The Guru is not aware of this method in use elsewhere. It does not seem that it would have significant effect unless there are substantial daily variations .

How do you plan your media buy using the "recency" philosophy when advertising products with a long cycle re-purchase period such as an automobile?

The Media Guru Answers(Monday, August 16, 1999 ):
The central concept of recency is that the message received closest to a purchase decision is the most effective message. Continuous advertising will reach more people at any given time and is best for products purchased all the time, no matter how long the purchase cycle. That is, no matter whether it's 4 weeks or four years. So the only question is whether there are always people in the market for cars. This doesn't mean you shouldn't vary levels at peak selling times.

what is considered the effective number of insertions over a year in 1.) daily newspapers, 2.) monthly magazines, 3.) bi-monthly magazines, 4.) weekly magazines. My client's campaign is business to business. We buy print such as WSJ, Forbes, etc and trade print. I can answer this on a common sense basis, keeping in mind the 3+ effective frequency theory, but is there research on what levels are most effective/optimal?

The Media Guru Answers(Friday, August 06, 1999 ):
First, review adjacent Query #2693 for comment on setting effective frequency.

Traditional planning has various theories about minimum levels in print media. It used to be common to set a minimum of one issue out of four in publications with frequencies ranging from weekly to monthly. Weekly frequency was more the norm in newspapers.

But this all has to be taken in a context of

  • whether print is the only medium
  • whether print is the primary or secondary medium
  • How deep is the print list

Effective 4 week frequencies above 3 are difficult to acheive in the print media you list; effective reach like this is more the province of broadcast, while print is more often aimed at depth of message.

For research on print reach / frequency and effectiveness try Newsweek Media Research Index and the Advertising Research Foundation InfoCenter For details about the InfoCenter, call 212-751-5656, extension 230.

Dear Guru! I've got the following question. Our client has a product to advertise. He has set advertising goals for the ad campaign. We defined the level of effective frequency needed to reach these goals. 1. What is the range of effective reach? For example, 30%

The Media Guru Answers(Friday, July 23, 1999 ):
Media plan communications goals should specify a level of effective reach along with specifying the effective level of frequency.

Basic, as well as more advanced media software, calculates reach and frequency, frequency distribution and reach at various (effective) frequency levels. Input is typically GRPs.

Setting an effective reach goal can be based on gut, such as reaching the majority of the target at effective frequency levels in 4 weeks, or based on sales predictions. For example, this might be an estimate that 10% of those reached efectively will buy and X number of sales are the goal. Then 10 times X are the number who must be effectively reached.

In recent years, more companies have been using Direct Response TV buys to maximize cost efficiencies. However, one drawback to this type of buying is the low clearance level of spots selected. Are there any statistics or research on predicting clearance levels for DRTV buys during the year (e.g., quantifiable factors for seasonality)? Thank you.

The Media Guru Answers(Friday, July 23, 1999 ):
The inventory pressure logically follows the cpm indices, which are widely available, but in any given week, surprises may occur. Since, in theory, DR advertiing pays for itself, you merely need to find a level to order that is sure to be more than the clearance will be. Whatever runs, runs, If more runs than you anticipated, it should pay off in added orders.

What are GRP's and what do they stand for in a media buy? I am an Account Manager and don't have the Media background but need to explain the GRP levels to my Product Managers. Please help.

The Media Guru Answers(Thursday, July 15, 1999 ):
GRPs are gross rating points, the pounds and ounces of media buying and selling. The target audience of an advertisement divided by the population of the target group is the ad's rating. The sum of the ratings of the ads is the Gross Rating Points. Plans specify how many GRPs of each medium to buy. For print, specifications are more often numbers of insertions in specific titles, but the GRPs can be calculated the same way and one plan compared to another.

Allowance must be made for :15 versus :30 GRP or half page versus full page. A given program or magazine has the same rating (GRP) whatever the ad size/length, but obviously there is more benefit from 100 GRP of :30s or pages than from 100 GRPs of :15s or half pages.

While there are different parameters ( creative, media, marketing ) to set the effective frequency for a media plan there seems to be no parameter for setting reach. What are the different ways to arrive at reach objectives for a plan

The Media Guru Answers(Thursday, July 15, 1999 ):
There are many approaches.
  • awareness goals: Ad awarness won't get higher than reach, obviously
  • comfort levels: When working with an effective frequency level, the Guru wants to reach the majority of his target effectively over four weeks
  • Affordability
  • recency: Recency says that maintaining some level of weekly reach is more effective than flighting, for products with regular purchase (threshold is 30 reach per week)
There are numerous variations.

The Media Guru Answers(Wednesday, June 16, 1999 ):
Yes, consumer experience, word of mouth, in store exposure all contribute to attribute awareness. And GRP to awareness translation is far from perfect.

For several years, I have bought my client's spring and fall campaigns on an alternating schedule i.e., one week on and one week off @ 200 TRPs per week. Historically, we take a four month hiatus between campaigns. Recently, someone told the client that it would be more effective to buy three weeks consecutively at lower TRP levels. Either plan would be restrained by a stated budget amount. Do you have an opinion about each of these strategies or your ownpreference in television buying strategy when trying to stretch the time on-air?

The Media Guru Answers(Sunday, May 16, 1999 ):
You haven't stated how many weeks of 200 on and off you run.

But, assuming you take a one-week-on / one-week-off schedule of 200 and change it to 100/week continuous, this will probably be more effective, particularly if your product is something people are buying continuously or regularly. Since reach can only go just so high, the average reach per week of 100 GRPs continuous will be higher than the average weekly reach of one week at 200 and one week at 0 GRP. So the continuous schedule has a better chance or reaching someone just as they are about to make a purchase decision.

This is the essence of the "recency theory."

How do you calculate reach "in-market", and are you to combine that with the national numbers? How is this done? Thanks. We are trying to show total "in-market" delivery. Also, back to the average 4 week dilemma, is it only relevant when looking at sustaining levels of a continuity plan? Or would you show average four week even in a launch, retail, or promotional type heavy-up situation? Thanks as always.

The Media Guru Answers(Monday, May 10, 1999 ):
Suppose you had national media with a reach of 40% and a local media plan delivering 50%.

You would combine the national reach of 40% with the local 50%. If you care to go the extra step, you could analyze local variation in delivery of the national plan and adjust the local delivery of the national media before combining with the local. Or if you run only national media you can look at the locally delivered weight to caculate the in-market reach resulting from national media, as if it were local spot media.

Four weeks is a traditional standard measurement period. This standard goes back to the days of the dominance of monthly magazines as an advertising medium. There are numerous ways this rule of thumb is used. Some look at "4-weeks-when-in" and examine four weeks worth of average activity no matter ho many active weeks a plan has. This focuses on the rate of advertising rather than the quantity. Other focus on cume of whatever number of weeks. One has to make a judgement of what tells the story best. The judgement can be made differently when you are comparing possible plans and when you are trying to quantify potential effects on awareness, sales, etc.

What is the minimum weekly threshold level of Reach & Frequency to be set for a print campaign [ Full page colour] ? How different would be the same for a television campaign [ 30 secs TVC]?

The Media Guru Answers(Monday, May 03, 1999 ):
There is no absolute standard. Recency theory calls for about 30 reach as the weekly threshold. The Guru believes virtually any reach is worth something, but careful analysis of the sales or consumer response needed to support a level of spending can always be done.

To the Guru's thinking, the only reason to have a different threshold for TV vs print is that typically, the frequency levels accompanying a given reach in magazines will be lower than the frequency for the same reach in TV, assuming your reach is at more than a minimum level. (A reach of 10% in either, achieved through one advertisement will have a frequency of 1.0).

Dear Guru, Over the one year that I have been following the queries and discussions on this web sites, what strikes me is that while discussing a Media Plan,there is no mention of involvement as a factor when the consumer is watching television. Do media planners not take into account the involvement levels of the audiences while planning ? Why is it that we talk of Reach/Frequencies etc and not about Involvement? Are there any publicly available studies on the same ? If not, is it legitimate to assume that agencies.. 1. Do not look at Involvement while planning 2. If they do, they do so based on certain assumptions and not on hard data. Thanks

The Media Guru Answers(Monday, April 26, 1999 ):
In the early '80's, a service called TAA (Target Audience Assessment?) offered audience involvment ratings. The service didn't last long.

Long before that and since then, factors like audience attentiveness have been used to judgementally adjust media audiences in media planning.

The new "Optimizers" allow easy overlaying of these factors and other involvement indicators like audience loyalty, in planning and buying.

However, the Guru imagines that more plans (though perhaps not more money) ignore these factors than use them. They are abstractions of unproven value in judging the sales power of media.

The most likely publicly available source of such data would be Advertising Research Foundation InfoCenter For details about the InfoCenter, call 212-751-5656, extension 230.

AMIC's Rates, Dates and Data area provides some of these attentivenss factors.

My client was told from a previous agency that 100 points a week is a standard guideline for television advertising, for sustaining levels. I know there are tons of factors that would really go into developing point levels, but other than showing r/f and eff 3+ numbers is there any way to source this or provide rationale? The client is looking for it. Thanks as always.

The Media Guru Answers(Thursday, April 08, 1999 ):
As a regular correspondent of the Guru's you certainly knew that an agency saying 100 GRP / week is "standard" is a sign of ignorance, at best, and you've come to the Guru for help in debunking this nonsense.

Looking at the 4 week reach of 100 GRP / week might show a 100% variation in reach, frequency or reach at 3+ based on daypart choice, for Adult 18-49. So ignoring whether daytime or prime is used is foolish. Will 50 GRP/week of Prime do the same communication job as 100/week in day?

When GRPs are seen as just weight, with no consideration of programming content, reach potential, frequency, etc, one suspects media planners have not even gotten into the game.

Factors such as how high is the introductory weight, how high is the competitors' weight how long are flights vs hiatuses, should all influence a choice of sustaining weight.

The simplest way to rationalize for your client is to show how different the reach and frequency of 100/week can be and what the competition

I have been researching these questions for a number of days now and have been unsatisfied with the answers I have been receiving. I am a new member and new to this field, any direction would be most helpful. Thank you in advance... 1) What is the difference between Rate Base (a number guaranteed by publishers and audited by ABC) and Readership (a number provided by, say, MRI) levels for magazine publications? 2) Which number (above) is most often used to calculate CPM (I believe this calculation is ad_page_rate/readership)? 3) Is 'readership' really a composite number (perhaps a result of some other formula)? If so, does Page Exposure Rates factor into 'readership'?

The Media Guru Answers(Tuesday, March 23, 1999 ):
If you went to AMIC's Rates, Dates and Data area and clicked the link
"Audience data from MRI is available for
Fall 1998 for Total Audience, Circulation and Readers Per Copy
" you would see the table from which this image is taken:



The following discussion will use this table as a visual aid.

"Rate base" refers to circulation, the actual number of copies of a publication printed and sold for the average issue over a specified period of time. In the table, "Circulation" is the middle column of data.

"Readership" is the number of readers of the average issue. It includes "passalong" readers, who may not be the buyers / subscribers but read some else's copy. In almost every case, total readership will be greater than circulation. The first three columns of the MRI table we are looking at are readership numbers.

CPM can be calculated based on either circulation or readership. The circulation CPM (Cost Per Thousand) calculation is: divide ad cost by the number of copies in circulation.

The readership cpm calculation is: Divide ad cost by number of readers of an average issue. Often readers within a specified demographic the advertiser is targeting are the divisor in this second calculation. As a planning tool, the readership CPM is more common than the circulation CPM, especially for categories of print that use readership research, such as MRI.

Many people misinterpret the common reporting of "readers per copy." The last three columns of the MRI data are readers per copy figures. What audience research actually measures is readership. A random sample of consumers is interviewed and asked about their magazine reading to determine how many readers there are for an average issue of a magazine. Readers per copy is a calculation done after the fact, dividing the readers measured by the circulation. It is a handy factor used to compare magazine pass-alongs or to calculate other audience elements.

I am a student working on a media plan for a new product in the fast food industry. The restaurant is well established and my target is 18-34 males. I am in the Lexington, KY market and wondering what would be a good reach estimate.

The Media Guru Answers(Thursday, February 25, 1999 ):
This question lacks most of the necessary information. First, the Guru must assume that you want to know what would be a suitable reach Goal. Establishing communication goals in a scenario like the one you describe will depend mostly on the competitive climate: what levels are being acheived by the other advertisers seeking the same target for similar products?

At times the standard can be based upon levels that the same advertiser has found to be successful in prior launches, but that too should depend on judging whether the competitive climate this launch faces is comparable to what was faced by the prior successful launch.

HELP!!

The Media Guru Answers(Thursday, February 18, 1999 ):
Congratulations, today you are a media planner. But apparently you are working with people lacking professional advertising experience or perhaps a retail client.

You either need some marketing goals input or you need to suggest some goals and get agreement before proceeding. You have been presented with a question equivalent to "how many pounds of nails are needed to build a building?"

You need to know how big a building, what materials it will be made of, how many nails in a pound, to what use will it be put and how big must it be?

To recommend schedule weights you need either a budget or a communications goal to deliver. In media / marketing terms you need to establish -- whether you are given direction or someone accepts your suggestions:

  • What has priority: Reach or frequency?
  • is there a minimum reach or effective reach to attain; per week, in four weeks, or in total?
  • To help answer those questions, if no simple answer is available, you might ask is it a new or established product or service?
  • What levels are used by the competition, if any?
  • Are there any specific product awareness, ad awareness or sales volume goals?
  • (In planning advertising, assume everything is a result of advertising: there is no awareness among people not reached; there are no sales to people who are not aware of the product.)

Knowing all this, you could examine reach frequency and continuity impact of various levels and combinations of your media choices. In other words, you somehow need to establish what must be accomplished by the GRPs, before you can decide how many to use.

It is puzzling, in this great information vacuum, that someone has decided to "spike" certain weeks. Apparently there is some information around which you haven't yet been given.

How are effective frequency and reach levels determined for new product categories?

The Media Guru Answers(Tuesday, February 16, 1999 ):

Do you have an opinion on the media weight required to revitalize an ailing brand (a former success story which has been performing poorly of late). Should we stick to conventional weights, or heavier weight to try to make more powerful impact?

The Media Guru Answers(Tuesday, February 09, 1999 ):
Questions like this come up so often, and lead the Guru to ask more questions:
  • How sure are you that the Brand's troubles stem from the advertising weight rather than the advertising copy or product attributes or competitive pricing or competitive quality?
  • What levels are competitors using?
  • What media are competitors using?
  • What media will you use?
  • etc.

A simple answer, when you believe advertising weight or exposure of a new message is the core issue, is that you must deliver more impressions than the competition, by a noticable margin, say 20%.

For a national product launch, what are "typical" TRP weight levels for network tv, say for a launch that is scheduled for 8 weeks?

The Media Guru Answers(Wednesday, January 20, 1999 ):
No such thing. It's a classic case of "it depends".

  • What is the category?
  • Who is the target?
  • Is it a unique product or in a competitive field?
  • Will there be any other media / PR / other marketing communications?
  • What is consumer awareness of the category?
  • Is it a high-involvement or low-interest category?
  • Is it from a well regarded parent company or an unknown?

With a new product, you want to drive reach as high as possible with adequate supporting frequency. As a rule of thumb, few would start lower than 100 TRP / week.

The Media Guru response of Dec. 4/98 was that "common products . . . bought recently" are best candidates for recency planning, as opposed to products involving "considered purchase," such as automobiles. Not every- body buys even "considered purchase" items on the same day, so does it not make sense to spread impressions over entire year, perhaps on basis of % sales by month? My experience in grocery packaged goods designing Test vs. Control experiments on different ways to execute "recency" supports Erwin Ephron's work. Same approach should apply to even automobiles, it seems to me -- unless someone has conducted experiments proving the contrary. Have you seen such evidence, or are you speculating. There are many myths about recency. My experience is in Canada, where I am a consultant specializing in recency.

The Media Guru Answers(Friday, January 15, 1999 ):
That Guru response combined readings of Erwin's published work on recency, conversations with Erwin, and some of the Guru's own thinking.

Your excerpt is inaccurate, however. The Guru referred there to "common products bought regularly."

In that response, the Guru also stated that recency does not require even levels of continuity, but that seasonal sales peaks can certainly be reflected in plan levels. This would likely fit the automotive situation.


Thursday, January 07, 1999 #2249
Dear Guru! Are there any references or research done which support a recommendation for 2+ reach when tv advertising strategy is focused on frequency? (I happened to find only such that support a 3+ reach recommendation). Thank you for your help.

The Media Guru Answers(Thursday, January 07, 1999 ):
In the Guru's opinion, 3+ became a popular base level because of classic research from 1883 by a physiologist examing learning of nonsense syllables. He found 3 repetitions to be the crucial level.

Many people have come to use 3+ as a rule of thumb and others using various analyses of competition, clutter, product interest, etc have judgementally justified levels from 2+ to 9+. It is essentially a judgment and selling excercise.

I am currently analyzing a media schedule that includes consumer print, trade print and national cable. I have been asked to pull a reach and frequency for the entire schedule. I realize that I am working with several differenct universes. I have added the circulations and pulled the gross impressions for cable. I have added those together. Is there any formular to determan a reach and frequency? Help?

The Media Guru Answers(Thursday, December 24, 1998 ):
In general, different media have different audience accumulation patterns when thinking about net unduplicated audience vs gross audience.

Calculating reach from a total multimedia impressions number is not practical unless the gross rating points (impressions divided by GRPs) is so many thousands that a 95+ reach can be assumed.

Some media, in particular broadcast media, allow general estimation of reach from a table of GRP levels. Print media are more complicated.

What you really need is standardized media software for reach and frequency calculation like that which is offered by AMIC 's sister company, Telmar.

Dear Guru, How would you define the role of a media buyer? And what would you say are their principal tools and techniques?

Have you any suggestions as to where I can obtain information on media buying from a complete novice angle? How closely are media planners and buyers related if at all?

The Media Guru Answers(Saturday, December 19, 1998 ):
Generally, a media buyer's role is to negotiate the purchase of broadcast time or print space in accordance with the goals established in the media plan. More often, people with the buyer's job are broadcast specialists and print is often negotiated by the planners. There are more and more print specialists. This differs from country to country and according to agency size. Smaller agencies in the U.S., for example, often use planner / buyers.

Tools are the research to evaluate the value and appropriateness to fulfilling goals of the media possibilities. The techniques use various calculations and evaluative processes to compare media and negotiating techniques applicable to any form of negotiation.

The media planner's job is to determine which media will meet the advertising goals of an advertiser, within stated marketing and creative parameters. This means selecting media, designating vehicles within the media, determining levels of media to use and timing.

For the basics, try one of the media planning texts from Amazon .com in the AMIC Bookstore.


Friday, December 04, 1998 #2198
Dear Guru. Thank you for your answers - they are very helpfull to me. My question is on "recency". 1.What groups of products best fit for "recency" planning. 2."Recency" planning needs continuity. But it is not evident what frequency level is needed at every moment of such continious ad campaign. It seems reasonable to set more frequency at the launch period and then decrease frequency for mantainance. Also we should take into consideration seasonality. Thus our campaign becomes pulsing but not continious. What are your comments? Thank you very much.

The Media Guru Answers(Friday, December 04, 1998 ):
1- Recency seems to best fit common products that are bought regularly; in other words, a purchase is stimulated by running out of the current supply. This means food and HBA products, primarily. More "considered purchase" products, like automobiles, may not be a good fit.

2- Erwin Ephron, principal proponent of Recency, has commented to the Guru that about 30 reach on a weekly basis is a threshold level. This might mean 50-60 GRP depending on the media used amd target.

Part of recency theory, in relation to frequency levels and effective reach, is that after three exposures have been delivered, every subsequent exposure is supported by adequate frequency. Recency generally applies to brands with established awareness; when you raise the issue of product introductions, it is a different situation.

Seasonality is the principal exception to recency. There is no point in delivering the most recent ad exposure at a time when no purchase is likely. It is important to distinguish products with seasonal fluctuations, like deodorant, from products with very specific seasons, like barbecue charcoal.

Also consider that Recency does not mandate even levels in its continuity. The weight can be raised above the threshold when appropriate.


Thursday, December 03, 1998 #2196
Dear Guru. I am interested in the "recency" theory very much. But unfortunately it is too hard to get the complete view of this theory just investigating your previous answers and "Ad Talk & Chats". So could you provide some main statements of the "recency" theory. Thank you in advance.

The Media Guru Answers(Thursday, December 03, 1998 ):
The essence of the recency theory is

1- that the last ad exposure before a purchase is the most influential.

2-That this last exposure is more powerful than less recent, more frequent exposures.

3-Therefore, continuous advertising will outperform the same total weight delivered in flights, because it offers more opportunities to be present closest to a purchase.

Of course, there are many sub-points regarding seasonality, minimum threshhold levels, and spontaneity of purchases.


Tuesday, December 01, 1998 #2190
Guru- Can you please explain Gross Weekly Reach Points (also refered to as levels)? How are they determined? Thanks.

The Media Guru Answers(Wednesday, December 02, 1998 ):
The Guru believes you mean "Gross Weekly Rating Points," a term often used to mean "levels." "Reach" is a term referring to the net, or unduplicated, audience.

Gross Rating Points are the sum of all the ratings of all the announcements or insertions of the campaign, or the sum of all the impressions of the announcements, divided by the population for the relevant target demographic.

An "impression" is created every time an audience member is exposed to one advertisement.

Are there any current studies out that addresses clutter / attentiveness / dial switching due to expansion of commercial tv breaks? I.e. Threshold in number of minutes whereby at XXX break length viewer attentiveness / retention of commercial ads drops off? While I know that program content, channel availability (cable versus non-cable) remote control, demographics, and time of day affect overall attentiveness, I'd like to see if a white paper was available to address this issue. Your help is much appreciated.

The Media Guru Answers(Sunday, November 01, 1998 ):
Since all the independent variables you cite are responses to many of the other driving forces you mention other than clutter, it is difficult to concieve research that would correlate attentivenss to growing clutter. On the one hand "clutter" might be defined as expansion of commercial breaks. On the other, it is almost assured that commercials within longer breaks are more likely to suffer form lowered attentiveness and channel swithching. Nielsen audience flow studies are available to correlate channel switching with timing within break. TVB or CMR (Competitive Media Reports) reports should track trends in length and number of breaks

Generally, the Advertising Research Foundation library is the best source for published research on your broader topic. Their Journal of Advertising Research is the most prolific source. One such article is by Rober J.Kent: Competitive Clutter in Network Television Advertising: Current levels and Advertiser Responses. .

Abstract:

    Large differences in competitive CLUTTER exist across product 
categories, markets, dayparts, and program types. This suggests several alternative strategies are necessary to deal with growing CLUTTER.

We have a client who is interested in utilizing Network Radio over a two-month period (January and February) to help maximize the awareness of a new brand. Is there any research that correlates radio TRP levels with brand awareness levels to give us some direction on how many points we should buy for the period without generating too much wearout? we should buy? brand.

The Media Guru Answers(Wednesday, September 23, 1998 ):
Awareness is more likely to correlate with reach/frequency than TRP's. Only those reached can be aware. The same level of TRPs might reach 40% of a target or 60% depending on the schedule.

The Guru has seen research that shows that any level below 100 TRP a week in TV allows awareness to decay.

Most research on wearout which the Guru has seen ties wearout to frequency i.e. a commerical is worn out (loses sales effectiveness) after "X" exposures. This may be expressed as the frequency in the next-to-highest quintile. I.e. the 40% most exposed to the commercial would have "X" or more exposures. 25 exposures might be the threshold level you choose. This level would occur at about 200 TRP/week for 8 weeks, which is more than the Guru would guess you would buy.

By the way, one Adult 18-49 plan with those quintiles would have a 66 reach. Another plan with the same TRP's and different schedule could have an 85 reach and just 22 exposures in the next-to-highest quintile.


Thursday, September 03, 1998 #2026
Both we and our client agree to the recency theory. The problem is that given the retraints of the budget, we are only able to schedule "weekly" advertising for about half the schedule while still achieving minimal weekly TRP threshold levels. Right now we are wrestling with the dilemma of how to schedule these weeks for the first half of the year while still following the principals of the recency theory: (1)12 weeks straight through then a 14-week hiatus (2)6 weeks on, 14 weeks off, 6 weeks on or (3)an alternating schedule of 4 weeks on and 4 weeks off, etc. throughout the period. Do you have any theory on what might be the best approach to maximize return?

The Media Guru Answers(Thursday, September 03, 1998 ):
Thinking about a "threshold level" of GRP's is instinctive, but at odds with the essence of recency theory. Review other Guru answers below about recency. Please also see a very interesting discussion of recency on our MediaPlanning e-mail list. The list archives are at Ad Talk and Chats . Why not subscribe to the list and bring your question there as well?


Monday, August 24, 1998 #2011
We are in the process of planning for a major TV client where we have been applying the recency theory for the past year. Because of the size of the budget we have been limited to around 70TRPs weekly essentially for the entire year. In Year II our client has asked us to consider temporarily abondoning the recency theory and to move dollars (and TRPs) out of the more expensive buying months (April, May) to the relatively more more inexpensive months (January, Feb)and to increase our TRP levels accordingly. Do you have any input on which strategy should/could have more effect on brand performance assuming all other factors are equal (pricing, distribution etc.)?

The Media Guru Answers(Monday, August 24, 1998 ):
First we have to assume that the basis of recency theory is accepted.

Recency theory calls for reaching as many people as possible as close to the sale as possible. Thats's why continuity is emphasized for products with little seasonality and regular purchase cycles.

One of the essential elements of recency theory is that not all impressions or GRPs are equal, even in the same programming. You are focusing on cost per point. As you are probably aware, reach developed per GRP decreases with every added GRP in a schedule. There is therefore, a declining return on investment in reach at any point in time, which is why spreading out prospects reached produces the optimal return. The first 10 GRPs bought in a week generate more reach than the last 10 GRPs.

Hence, the added impressions bought when they are cheap produce less sales than the impressions lost from the more expensive times.

So now you have to evaluate what might be produced. Assuming you are lowering -- not eliminating --activity in higher priced periods how many more impressions, and how much more reach can you achieve in low priced times. If you cut back 10 reach points per week in July but buy 20 added reach points per week in March, perhaps the added reach can sell more than the lost reach, or perhaps not. The Guru would look for a 50% minimum trade up in added vs lost reach points to justify the change; i.e. if the plan goes down 10 reach points per week in one period, then it need to go up 15 reach points per week in the other.

I need help! I need to know the forumla (or formulas) for figuring the reach and frequency on a television schedule. I need it to be demo / and have the following information: universe, impressions and grps. What else do I need and what is the magic FORUMLA! At this point we are using the cumulative impressions into the universe to figure the reach - but could that be right? I don't think so - but the reach is what I need to figure (already have grp and freq is easy if I have reach!). Please help - and thanks tons.

The Media Guru Answers(Friday, July 24, 1998 ):
When you divide the accumulated impressions by the universe, your result is GRPs. There is no simple reach formula unless you already know GRPs and frequency. There are various very complicated algorithms for calculating reach for a given average rating size, known average duplication between programs used, etc. "Beta Bimodal" is one of the best known.

But today, Reach calculations are done by computer, using models built from Nielsen's actual measurements of net audience reach from meter-measured schedules.

Telmar, AMIC's sister company, is the leading provider of software for such analyses.

Before computers were commonplace, media planners had tables which gave reach for various GRP levels depending on demos, dayparts and duplication. These, too, were based on average Nielsen audience accumulation reports.

I am looking for any guidelines / research about: 1- number of spots for radio (sustaining level, 50% heavy up, 100% heavy up 2 - if I have continues strategy what maximum gap of not being on air may I allow without harm to sales (one week, two, three?) 3 - in my country (Russia) we have practice in outdoor not to place competitors on two opposite sides of billboard, ahzt I think is not correct, as each face of billboard works for different directions and can not compete with each other. What is the practice regarding this in other countries. Thank you very much.

The Media Guru Answers(Tuesday, May 26, 1998 ):
1) The Guru doesn't judge radio effectiveness in terms of numbers of spots. If one schedule of 12 spots, for example, has an average rating of 0.5 (one-half of 1 percent of the target audience), which is common, it cannot be considered equal to another station's 12 spots with an average rating of 2.5 (also reasonable for top stations in the US). The first accumulates 6 GRPs and might reach 3% of the target, the second accumulates 30 GRPs and might reach 12-15% of the target.

So GRPs' or other audience measure are more realistic ways to determine levels. Having done this, if you determine that 100 GRPs, for example, is the correct sustaining level, then by simple arithmetic, 50% heavy-up is 150 GRPs and 100% heavy-up is 200 GRPs

2) Awareness begins to decline as soon as there is any advertising gap. Current thinking is that sales of a continuously purchased product are better supported by continuity at whatever level is affordable rather than an arbitrary minimum effective weekly level, separated by periods of inactivty. The U.S.'s Advertising Research Foundation has considerable literature on the topic and so might ESOMAR , the European Survey, Opinion and Market Research organization

3) The Guru agrees with you regarding opposite sides of a billboard. The competitive protection policies the Guru is familiar with in the U.S. only deal with advertising seen by the same audience, that is, traffic headed in the same direction. Usually there will be a certain range specified, such as "Within 500 feet" for metropolitan 8-sheet boards, which are about 5x12 feet and can be placed in dense concentration within cities.

how will media segmentation affect media planning ?

The Media Guru Answers(Monday, May 18, 1998 ):
"Media Segmentation" is a two edged sword. Highly segmented (fragmented) media allows better targeting. But, at the same time, it works against building higher reach levels.

A clever plan will find the best compromise between these two.

The current, "recency" approach to planning can take advantage of the efficiency of reaching lower levels of target consumers on a more continuous basis.

we are in the process of recommending to a new client a media strategy that will help him sell more olives and cucumbers (both products in either can and glass containers). The client has a large marketshare, about 42%. Neither this client nor competitors have ever advertised their products. In this respect the category has been rather dormant. What guidelines can you provide regarding a 3 year plan. Since the company name is very well known, does it make sense, for example, to 'fortify' TV advertising with radio? Providing that radio has very good reach, is there a synergetic effect with TV or is the money better spent in one media? Thank you Irene Kol

The Media Guru Answers(Thursday, May 14, 1998 ):
Modern thinking for such products emphasizes reach over frequency. It is more important to have some presence at any time that a purchaser might be making a purchase decision, than to drive reach to high levels (with more frequency) over a short campaign.

One guideline tha comes from this is to make a media mix more valuable, since a secondary medium almost always adds more reach than additional investment in the base medium.

Assuming then that you can afford an acceptable minimum continuous level of TV, addding radio will be wise.

No matter your client's awareness and market share, the first entry into advertising in this category will probably change the picture.


Monday, May 11, 1998 #1587
Is there a correlation between GRP levels and awareness? If so, what GRP levels are recommended to significantly effect awareness? The category I'm looking at (long term care insurance) has low consumer awareness, and a high avoidance factor.

The Media Guru Answers(Monday, May 11, 1998 ):
In its simplest terms, there is a correlation. Obviously, the more GRPs delivered, the more awareness is created. Creating new awareness will take more GRPs than sustaining existing awareness.

A safe minimum guideline is to continuously reach more people than the existing level of awareness.

It is also important to remember that awareness alone doesn't make a sale. The message must be persuasive, not merely one of which the prospects are aware.


Tuesday, March 24, 1998 #1549
Dear Guru, do you have any information regarding internet usage and seasonality? For instance, do overall online visits decrease in the summer, just as TV PUT levels decrease?

The Media Guru Answers(Monday, March 30, 1998 ):
The Guru suspects not.

-Heavy internet users tend to be of the same type as lighter TV viewers, anyway.

One may be able to get toplines from Media Metrix or Relevant Knowledge, the only monthly, survey measures of the web which are at least partly released to the public.

what is the correct television weight for a campaign

The Media Guru Answers(Monday, March 30, 1998 ):
The "Correct" weight depends on many factors, there is no one correct weight.

One way, but certainly not the only way, to calculate an appropriate level is to follow this checklist:

  • (A) How many new sales / product units, etc are your monthly sales goal?
  • (B) What percentage of the prospects who are successfully exposed to your campaign are likley to buy what you are selling?
  • Divide (A) by (B) to determine with how many prospects per month your advertising must effectively communicate.
  • Using the reach and frequency calculating system of your choice and your judgement of "effective levels of communications, calculate what level of weight delivers the desired effecively reached audience.

Can you explain what "mapping software" is? And, do you know about a software package called "Clarisoft" or something like that?

The Media Guru Answers(Thursday, January 15, 1998 ):
There are probably several meanings of the term, created by different software makers.

In a media context, the term usually refers to software which can draw a map colored or shaded to reflect demographic, media or product usage behavior.

For example a DMA may be drawn, and colored to indicate which zip codes have the highest circulation of the local newspaper, a national magazine, or TV show audience. It is common to separate zips or other sub areas into quintiles or tertiles, etc.

The entire US may be drawn to show sales levels of a product or BDI by DMA.

A three mile trading circle around a store location can be created to show media income of census tracts, for planning the distribution of a circular.

Claritas PRIZM, Donnelly's Cluster Plus, and other segmentation systems are typically used to analyze or model the data. There has been considerable consolidation of software vendors in this field in the last few years. Compass, Conquest, and Strategic Mapping have all folded into Compass.

Dear Guru Could you please give me your views/suggestions on the following: 1. How can you set media objectives for a banking client in a market with only two major competitors; both of whom do not have a clear-cut advertising campaign? Would a % above last years GRP levels be appropriate; in proportion to the market share desired? What other parameters should I consider? 2. Qualitatively or quantitatively, how can front page solus positions in newspapers be compared with inside pages and ear panels? 3. And lastly, how do you add TV and press GRPs; for a specific audience? Sorry about the long query. Thanks in advance

The Media Guru Answers(Saturday, October 18, 1997 ):
As a rule, the Guru sets media objectives based on marketing goals, not competitors' activity. Some marketing goals do indeed lead one to comparsions with competition, and awareness of competitors' plans is always a consideration.

If the key marketing goal is share growth, then a proportional increase in weight is one approach. But consider that share, like reach, exhibits an asymptotic curve. In other words, it can't pass 100%, so the higher it goes, the more effort is required to "move the needle."

Consider: You first assume that "X" amount of GRP's are required just to maintain share, on the assumption that competitive activity doesn't vary (and that advertising is the only variable influencing share).

Have you considered whether current share is proportional to share of GRP weight among competitiors?

Would 50% more GRPs grow share by 50%? No, if only because it increases the size of the total advertising arena. Your 50% increase in GRP does not increase your share of GRP by 50%, so calculate the right number to increase share of GRP, if you follow that philosophy.

But since there are competitors, perhaps it takes 50% more weight to gain 25% more share?

Newspaper positions can be compared on a basis of noting, reading, recall, etc. In each country or culture (you are writing from India), the relative power of media and the way consumers relate to them are different.

In the U.S., for example, a front page ad in a newspaper would be quite unusual if not unheard of.

Contacting the U.S. Advertising Research Foundation or ESOMAR, the European Survey, Opinion and Marketing Research organization, or your own country's newspaper advertising association may turn useful up research on positioning.

The Guru treats GRPs of different media as simply additive. When there are established effectiveness factors, as some advertisers have developed, GRPs may be accordingly adjusted before adding, in comparing plans.

Dear Guru, I have a set of urgent questions to ask of you. I have a meeting tomorrow, and need your help! 1. How is effective reach calculated? 2. Reach v/s Frequency -- when should one be given priority / importance over the other? 3. Is there any way of taking creative into account while analysing competition? If yes, can a system of weights be worked out? 4. How do you reconcile to the vast difference between reach/frequency deliveries from a Peoplemeter system as opposed to the Diary system? My client refuses to accept a 4+ reach of 30% being accustomed to levels of 70% for the same plan! Would greatly appreciate your immediate reply.

The Media Guru Answers(Thursday, June 19, 1997 ):
1) In any schedule of several commercials, some of the target group will see only one, some will see two, some will see three, some will see four, some five, etc, etc.

The actual measurement is based on tracking the cume of several different advertisers schedules in a single measurement period such as one month of the PeopleMeter.

A mathematical model that will match the measured GRP/Frequency is calculated so that plan deliveries can be predicted. Going more deeply into the actual measurement, it can be determined how many people of each demographic group were exposed to each commercial in the schedule and a model calculated which will predict that performance for a plan.

For example, below is the typical output of a computer models' frequency distribution, showing what percent of the target saw exactly n commercials and what percent saw n+. (this example is from Telmar's ADplus):

                    Frequency (f) Distributions

                           10+     1.6    1.6   
                           20+     0.0    0.0    

2) Reach vs Frequency: The determination of emphasis here can be a complicated analysis making up the greater part of a plan's documentation, under the heading of "communications strategy." A commercial so powerful that it's sell is overwhelming in one exposure might take the "Let's buy one spot in the Superbowl" route as did the Macintosh computer with the classic "1984" execution.

In more competitive situations, competitors' levels are taken into account, clutter in the media of choice, copy quality, etc. Obviously a balance must eventually be struck between reach and frequency based on judging all these factors.

3) There are several ways to take creative into account while setting up reach vs frequency goals;

The complexity or simplicity of the message

The number of commercial in the pool

how close your commercial is to the established "wear-out" level

The balance of :30 to :15

etc, etc. can all be assigned factors and totalled or averaged to give a reach vs frequency emphasis factor

a similar exercise can also set effective frequency thresholds

4) There should not be "vast" differences between effective reaches based on people meter and diary systems if schedule GRP and other aspects are the same. 5 or 10% would be the range the Guru would expect.

A plan with a 70 reach at the 4+ level would be delivering in the range of 98% total reach. It sounds as if your client may be confusing a plan with 70 reach and an average frequency of 4 with 70 at an effective frequency of 4. Or perhaps confusing 4-week reach with a long term cume?

test marketing, specifically media weight tests.Using sales as the criteria--what % of these tests produce readable results; what, if any,are the minimum weight levels recommended for testing and any other insights you can offer.

The Media Guru Answers(Monday, May 05, 1997 ):
Different players have different rules-of-thumb. Since these tests are inherently proprietary, there will not be a large scale data base from which to generalize.

Large, testing-oriented companies, like P&G will have better informed "rules-of-thumb."

What per cent produce readable results is a somewhat vague question: "What percent produce positive results", or "What percent of tests are run for the full duration" are more practical questions. It is the Guru's understanding that, in either case, the answer is less than half.

Whole books exist to consider the variables which can blur the simple concept of weight test, such as mix, copy pool, number of stations or programs or magazine titles or continuity, which would likely change in execution of a greatly different weight.

What, after all, is the likelihood that more of the same advertising would not sell more than did a lesser quantity of advertising? In the Guru's experience, 1/3 has been the minimum considered testable, with 50% preferable. The Guru suggests the many articles on the subject published by the Advertising Research Foundation's Journal of Advertising Research.

I am trying figure out the best way to calculate reach & frequency for the following:

Television Flight:
4 consecutive weeks (250 TRP's per week)
Then scaling back and running 175 TRP's per week - Every other week for the following 8 weeks.

How do you calculate R&F when your schedule runs on an every other week basis?

The Media Guru Answers(Monday, February 24, 1997 ):
There is no basis for believing that an alternate week schedule of 700 total points (175 per week for 4 of 8 weeks) cumes to a different total than 87.5 grp per week for 8 weeks, as long as the scedules are otherwise identical in numbers of different announcements, and numbers of different episodes of the same programs.

It is true that if the schedules per week of activity were solarge as to exhaust reach potentials, the answer might bedifferent, but this is far below such levels

So the total schedule of the first four weeks at 250, plus the 4alternating weeks can be calculated as if there were lower levelconsecutive weeks.


Monday, February 17, 1997 #1045
I am interested in obtaining research that explores effective consumer promotion television weight levels. A typical consumer promotion window may be 2 - 3 weeks. Most consumer promotions are planned in the neighbourhood of 300 GRPs / week. Is there any research that has measured effective levels. I am trying to identifity an optimal level, a level (or range) below which response/sales suffer and/or above which response/sales do not substanitially increase.Goal- avoid spending too little or too much against a given promotion.

The Media Guru Answers(Friday, February 21, 1997 ):
There are so many variable beyond GRP weight that the Guru doubts you will find simple answers.

Just a few are copy length, daypart mix, competitive arena, product interest, and commercial quality and wear-out status. Further, the Guru thinks that effective reach / frequency is a more useful quantitaive standard than pure GRP.

Two places to look for relevant research would be Newsweek Media Research Index or Advertising Research Foundation


Wednesday, January 15, 1997 #1077
Wow, who knew?
there was someone like you
the great media guru!

My question...Where can I get more information on the retention of advertising within a commerical cluster...specifically radio advertising. I've heard the first and last commercial have the highest retention levels, but I can't prove it. Any suggestions?Thanks.

The Media Guru Answers(Wednesday, January 15, 1997 ):
The Guru would first try The Radio Advertising Bureau ( RAB) and also The Newsweek Media Research Index.

Dear Guru: Where do I look for information about the ethnic market?I am trying to establish average income levels, viewing habits,etc..

The Media Guru Answers(Monday, January 13, 1997 ):
Which ethnic market? If you mean African-American, Hispanic and Asian, the three largest commonly considered "ethnic markets" the Census Bureau's site is full of income and other info.

Tv viewing is reported by Nielsen Media Research or in broader strokes by studies like MRI or Simmons which has a specific Hispanic study.

Many other links may be found, on AMIC, at Abbott Wool's Market Segment Resource Locator

Media Guru:
What can you tell me about standard error? Specifically, I have three questions:
1. What goes into standard error? If not the actual calculations, can you tell me what affects standard error: it's not just sample size, is it?
2. What is the maximum standard error that is considered acceptable to the media -- specifically, the advertising -- industry?
3. Related to the previous question, do you happen to know recent standard error levels for suppliers such as Nielsen (National), Simmons or MRI?
Thank you for your attention to this humble query.

The Media Guru Answers(Saturday, December 21, 1996 ):
As the adjacent answer to your previous Guru inquiry details, standard error considers sample size and the size of the specific response. Standard error is smallest for a 50% response in a specific way. 10% or 90% answers have the same standard error. When you hear that a study, like a presidential poll is "+/- 3% that is usually the standard error for a 50% response.

It is interesting to note that the size of the sample is the key and not the relationship of the size of the sample to the universe. In other words, when a broadcast rating service uses a larger sample for New York than for Klamath Falls it does so because of the cost of larger samples being more affordable by larger market's media who sponsor the research, not because a bigger market "needs' a bigger sample. Also note that because of the square root aspect of the calculation, a sample must grow by a factor of 4 to reduce error by half.

"Minimum acceptable error" is quite situational. While an error of +/- 2 on a rating of 10 seems small, it becomes important when a buyer need to decide between programs rated 8,9,10,11 and 12 which might all have identical audiences yet seem to vary by 50%.

As stated above, sample size and response control standard error. Neilsen Simmons and MRI each give the information with their reports to calculate error appropriate to the individual report and findings. Most software used to generate reports has the option to display the error witheach cell of data reported. (You may have noticed single and double asterisks on tabulations of Simmons or MRI data, these are indicators of standard error ranges)

I was wondering what the effective levels of reach &frequency for a new product launch would be, as well as an adequate budget?

The Media Guru Answers(Friday, October 11, 1996 ):
Determining the effective levels and desired geographic scope will determine adequate budget.

There are no absolutes in effective levels for intros or any other purpose.

Issues to consider include:

  • Competition; how many, spending how much
  • Clutter in the media to be used
  • Typical levels of frequency in the media used
  • Complexity of your message
  • Interest in your product type - e.g. insurance vs sports cars
  • Ability of the target consumer to digest information
  • and others which may be specific to your own situation.

Generally, you want to reach the majority of your target at the determined effective level.


Friday, September 20, 1996 #1143
Can you access competitive information that may be proprietary?For example; can I find out what dayparts & spending levelsa competitor did for 1995?

The Media Guru Answers(Monday, September 23, 1996 ):
You can't get the proprietary version, but CMR (Competitive Media Reporting) is in the business or monitroing and compiling such information, now including Internet advertising.

My telecommunications client is planning a multimedia (TV, newspaper, radio) launch in Chicago this fall, hoping the phone will ring off the hook. Is there a way to predict response levels per medium (or in total?) for the client to effectively staff its phone lines? I have total population, target population, reach & frequency levels (for TV - a 6 week flight; for radio a different 6 week flight; print used in both flights). The kicker is: this is not a direct - response spot (of course, an 800# will be included, but generally, it's an image builder). I also know that it will depend greatly on many things creatively (length of time the 800# is on the screen, is it a pnemonic number, is there an offer, etc). I'm thinking if there is an easy answer to this, I wouldn't have a job.

The Media Guru Answers(Wednesday, July 24, 1996 ):
The safe answer is to contract an "inbound telemarketing"service which is large enough to expand or contract around your actual traffic. Depending on the offer and strength of copy, calls could equal .01% to 5.0% or more of persons reached. Using a service the first time out, especially if you're not specifically setting up a DR business, will give you benchmarks for the future.

I am convinced that with a limited budget it is necessary to reach "effective" reach levels at a given period of time rathe than spread thos dollars throughout the year to achieve low levels but high coninuity. I am working in the Automotive field. Please help me. I need specific documented research studies on effective reach!!!

The Media Guru Answers(Monday, July 08, 1996 ):
It isn't clear what your query is. Many people continue to feel as you do. In recent years, many others have espoused the "propinquity" theory which advocates continuous low levels, based on the idea that the single exposure closest to a purchase occasion is the most effective.

There has been considerable trade publication comment on the matter, most often by Erwin Ephron, probably the leading proponent of propinquity. A recent Advertising Research Foundation workshop devoted considerable attention to this issue, and the proceeding of that conference should be available from the ARF. There have been opposing positions, in agreement with yours, published as well, one of the earliest by Abbott Wool in Media Week shortly after Ephron's first publication of the theory.

The Guru has discussed this before, so using your browser's "find" function to scan this page and the Guru archives will provide additional material.

Surely the most archetypical exception to continuity is for the highly seasonal product, as automotive products may be.


Friday, May 17, 1996 #1213
Dear Guru,I have two questions which you might have heard before.
a)I do know that a :15s commercial on TV cost between 50% to 75% of a :30s depending on market etc. Is there any studies that show what the benefit of either length is (if any) in terms of reach, frequency, effectiveness, memorability, etc.
b)I have seen studies praising the advantage of multiple media usage above single media; in other words using TV and radio instead of just TV. Can you elaborate on that and update with new info about this topic. Reason being a client who would like to slash the budget down to just using TV for campaigns. I however feel that there is an added benefit in using multiple media.Please respond by Monday if you can.Thanks.

The Media Guru Answers(Sunday, May 19, 1996 ):
a) There is is no difference in reach and frequency between a :15 and a :30. In the same time period, they have the same audience, within the tolerances of research measurement.

On the other hand, a schedule using :15's in place of some or all the :30's will provide more reach and frequency, because it has more announcements, hence more GRP, etc, for the same budget.

When :15's started to become popular several years ago, there was considerable research regarding effectiveness versus :30's. The general findings were that :15's had about 70 - 75% of the recall of a :30. At the time, :15's were typically a network option priced at 50% of :30's so the trade off of price vs effectiveness seemed favorable.

b) Multi-media plans chief benefit is in reach development, though the effects of the added reach have ripples in many directions.

Adding a new medium adds more reach than adding weight in the same medium: There are more likely to be different people in the audience of a different medium, over a given period of time. This applies to effective reach as well.

There are a variety of philosophical approaches to taking advantage of this.

One approach says to build reach up to a minimum effective level in the primary medium first, before adding the next medium. Another says build the first medium to the point where the reach curve flattens, then add the next medium to resume reach growth.

A newer, different line of thought, the "recency" theory, de-emphasizes reach in favor of delivering messages to the consumer closest to the point of making a purchas decison. This argues for continuity, to reach more people at all times rather than highest levels in sporadic flights. Again, multi-media will produce more reach, but other theories of minimum weekly levels may effect scheduling, ie radio bought to a minimum of 12x weekly when active.

Judgements must also be made regarding whether TV and radio is perceived as the same message by the consumer. Of course, this same judgement must be applied to different executions in the commercial pool of each individual medium as well.

I'm working on a presentation on how media planning professionals go about determining a media mix, and how a percent of budget is allocated to each medium being used. It's a general presentation for a client who is not very familiar with media planning terminology or methods. So far my sources for info include a couple of similar documents that I and others that I work with have written in the past, and the media planning textbook (by Scissors). Do you know of any other RECENT sources of info, points-of-view, articles on this topic? Or have you answered a similar question recently? If so, please tell me the category under which your response would be filed (I have looked through several categories of your responses and did not see anything relevant to this topic). Thanks!

The Media Guru Answers(Tuesday, April 30, 1996 ):
In the broadest terms, the process may be thought of as

Marketing Goals ---> Marketing Strategies ---> Media Goals ---> Media Strategies ---> Media Tactics, etc.

A very simple example:

A marketing goal of increasing the number of users of product X might lead to a strategy of converting users of competitive brand Y.

The media goal might then be to optimize reach at effective levels of frequency among a demographic group matched to current users of brand Y.

The media strategy to achieve this might then be built by examining various media mixes to determine which produce the best balance of effective reach for the budget, within the creative limitations.

Of course this is just one possible marketing goal, one possible strategy that might emerge.

There are many ways to set reach goals, to set minimum effective levels or decide to apply the recent "proximity" or "recency" theory of exposure.

In short, one doesn't decide on percents of media and see how it turns out, one decides which media will best answer the marketing and media strategies. Often, some creative decisons have precedence: if TV is designated as the "primary medium" because of communications ability, need to demonstrate, etc, then the strategy migh dictate putting all money into TV "until the effective reach curve is exhausted."

There are infinite ways to express and measure goals and their achievment. Some standard media planning software, such as Telmar's Media Maestro, and Hispanic Media Maestro, allow easy examination of various mixes, instantly showing how reach/frequency/effective reach change as budget or schedules are shifted between media by the planner.

I am buying a radio schedule (100 GRPs/wk for A25-54) in a market that is approximately 28% black. The urban station in this market is relatively efficient, but is by no means a "must buy". In fact, there are about 10 stations with 9/10 of a rating point of each other (AQH rtg, M-F 6a-7p). This urban station claims that I must have at least one urban station on every buy or I will miss 28% of the market. I disagree. When buying so few points a week, I do not have the budget to buy as many stations as I like. A better use of the money would be to cover the various age cells in this broad demo and try to balance the male/female reach. My question is, What is your opinion on this subject? Is an urban station a "must buy" in this market any more than a country, rock, or news/talk station?

The Media Guru Answers(Friday, March 22, 1996 ):
There are several levels at which this question can be considered:

The essence is determining the true value of that station: "should you buy it", not "must you buy it"

- If you ignored the fact that this is an urban station would you buy it, based on the general parameters of the buy? Rating/efficiency/rank, etc?

Are you having a negative reaction to being told you must do it?

Do you really miss 28% of the market just by not buying that station? To what reach level are you buying? At 100 GRP / week you're not likely to reach more than 72% of the target in a typical 4 weeks, anyway. So if the station is the onlyone reaching its market segment, how much does it matter if that segementis the 28% you miss rather than any ther 28% of the market.

Is that station is the only one reaching its segment? It is likely that several other stations in a market with that high penetration of Black population also reach that audience, but perhaps with a lower audience composition. Check the schedule you will buy to see how its African-American audience reach compares to its general market reach. Perhaps it's comparable even without that station.

On the other hand, if that segemnt is important, reaching it in a culturally relevant program environment can substantially enhance selling opportunity.

Examine the product usage data about your client according to Simmons/MRI/Scarborough/MMR, etc. Perhaps the African-American consumer is far more valuable to your client as a prospective customer than is the general market, and that Urban station, with its good efficiency, is the first one you should buy, even if it does sell aggressively.

Can you fill me in on "recency"? Sounds like a complicated way to say low media weight, long duration? Is this correct? If so, can it work with a small budget?

The Media Guru Answers(Monday, March 18, 1996 ):
Recency does amount to lower weight and longer duration, but allows for more complex discussion. It is a theory which works in opposition to "effective reach." Effective reach is based on the fact that 3, or some other minimum number of exposures to advertising, is necessary for the advertising to be digested, understood and begin to effect consumer behavior.

Recency posits that an exposure close to the moment of purchase decision is the most effective, therefore maintaining a constant presence of messages is most likely to catch the prospect at the crucial moment.

Obviously, even within the recency model, the more exposure provided at any given point in time the better the chance of catching a consumer at the critical time. Recency argues for continuity, not for low levels, though it is often used to justify low levels.

Recognizing that truly seasonal purchases call for different scheduling than regularly cyclical purchases, the concept says that if a given number of impressions are affordable, all else being equal, those impression will generate more sales when spread consistently rather that concentrated into flights at a presumed "effective" level.

I would like to know if in United State exist any research, about outdoor reaching people. If exist, could you give me an explanation, and any address to try to get more information. How an outdoor campaign is evaluated in U.S.? How many people reach, this kind of study. Thank you in advance

The Media Guru Answers(Friday, February 02, 1996 ):
There are measurement sytems and standards for outdoor media in the U.S. Outdoor (more generally called Out-of-Home media, to include buses, bus shelters, subways, etc) is measured in GRPs as are other media. Outdoor GRP's are measured on a per-day basis, while broadcast media are more often thought of on a per-week basis.

Therefore if one buys 100 Adult 18+ GRPs of outdoor posters, the daily audience exposures (circulation) are equal to the Adult 18+ population of the market area. So a 100 GRP buy is about 3000 GRP per month (100GRP per day x 30 days.

Typical reach systems will report that this level of outdoor delivers a reach in the 90% range with over 30 frequency. You may buy 50 GRP or 25 GRP, of course. Even at these levels reach is typically 80+.

Years ago we talked of "100 showing" or "50 showing" which was sometimes the plant operators rough estimate of 100 or 50 GRP and sometimes just a pricing basis.

Outdoor sales companies, such as Gannett (212) 297-6413 can provide scehdule-specific reach analyses.

At what point does the efficiency of buying local cable diminish so that national cable is a more effective option?

The Media Guru Answers(Friday, February 02, 1996 ):
On an efficiency basis, local cable is almost never superior to national. The decision point is more likely to be out of pocket cost, though the Guru has seen instances of the same cable :30's priced at $50 nationally versus $250 in New York.

The analysis also depends on how large an area is useful to the marketer. If the whole country is geographically acceptable as potential consumers, then the only question might be how far will the budget stretch in delivering "acceptable" levels of weight. If only certain geographies are within the distribution of the advertiser, an analysis of the useful audience within the national cable coverage is needed before the efficiency comparison can be made.

There is no %US "rule of thumb". Local cable is variable enough in its cpm ranges that there often is no relationship of market size to cost.

what is the difference between general media and direct response television media? and would I ever recommend to my client DRTV as an inexpensive way of getting exposure?

The Media Guru Answers(Friday, February 02, 1996 ):
General TV and DRTV are different in the way they are purchased and in key aspects of the copy used. To qualify for DRTV, the copy usually must be selling something through an 800 telephone number. Mail is also possible, but the immediate nature of telephone response is preferable (900 number ads are typically under a different rate structure).

DRTV rates are usually based on half of the going rate for the time period. The concept of "going rate" is hard to pin down with any certainty, unless you are buying the same schedule at the same time as "general media." These half price schedules are typically in remnant time or relatively undesirable times late at night or early in the morning or weekends. They are also instantly preemptible. You can't rely on delivering a schedule of "50 GRP per week in prime and 75 GRP per week in early fringe" through DRTV.

General TV schedules are used to build awareness through planned levels of reach and frequency or timely impressions delivery during specific promitions or campaigns DRTV schedules are opportunistic buys, with each airing anticipated to generate a certain quata of responses for a product ready to sell at all times without specific timing issues.. DRTV advertisers often track resonse minute by minute to associate each call with the specific commercial airing responsible. This is in clear contrast with the awarenes building aspect of general media.

When your client measures "exposure" in reach or effective reach terms than DRTV is not an efficient way to get exposure. Those remnant timeslots are not reach builders.

A DRTV advertiser is generally selling something worth the investment in inbound telemarketing expenses for each 800 number order, and assuming a certain minimum of orders per airing. (You cant make money if a $5 an hour operator has to spend 10 minutes taking address, size, flavor and credit card info to sell a $2 item, unless you add $3 shipping and handling). This means it doesn't work for toothpaste, floor wax, soap or cookies, unless you're selling the $29 bag-o-groceries special.
