What is the differrence between avg. OTS & Effective frequency. Which is the most popolar measurement tool used for setting frequency objective & can you illustrate the differrence through a sum.

The Media Guru Answers(Tuesday, April 20, 2004 ):
OTS is generally a raw exposures count (impressions). One could take total OTS and divide by reach to get average OTS, which would equate to average frequency; that is, the average number of times any person exposed to the message (reach) sees the message.

Effective freqeuncy is the number of exposures JUDGED to be required before a person reached is affected by the message, e.g. remembers or understands it. Effective reach is the numer of people reached at this effective level. 3+ is probably the most commonly used effective frequency standard, but there are various models for setting the level. See the Guru's comments on the ostrow model.

What determins an effective Reach at a certain frequency? For example, I have worked on a piece of business where the net effective Reach had to be 60% at a 5+ frequency. I have also worked on a piece of business that required the net effective Reach to be 60%, but at a 3+ frequency.

The Media Guru Answers(Sunday, March 14, 2004 ):
The Guru is assuming you mean to ask "how does one determine the frequency level at which to consider reach "effective'?" One standard approach is known as the ostrow model. Click here for Guru discussion of this model.

Hi Guru, I have heard of one method of setting effective frequency. That is we evaluate the criteria such as : established compaign, complexity of message, well-known brand, high product clutter... by giving them marks depening on their level. This mark will be multiplied by coefficient of each criteria. The total mark will be used to set the effective frequency level for that product. Pls supply me with more info on that. Appreciate should you can give me detailed explaination on steps to do that or give me a source to refer. Another question is that how can we set effective GRP based on effective frequency level, reach curve,no. of phase ( what is no. of phase?).The reach curve we use hereabove is that of target group of the brand or of any else? Thanks a lot.

Dear Guru! Is there, to your knowledge, a "role of thumbe" when it comes to number of exposures necessary for one ad-observation in different media; for example 4+ in TV, 2+ for newspapers etc.

The Media Guru Answers(Sunday, August 26, 2001 ):
The Guru deosn't think there is a valid "rule of thumb" in this case. One could evaluate the schedule in each medium according to the 'ostrow model'

Hi ! Two questions 1. how do you decide which cume (1wk or 13 wk or 52 wk etc) to choose. 2. where can I find the details of the ostrows grid actual one with the scales etc. Thanks and regards

The Media Guru Answers(Wednesday, July 25, 2001 ):
1. Four week R&F is standard. Otherwise, if you need to examine a specific time period related to your marketing, use the closest cume.

2. The ostrow model aims at establishing the minimum level of frequency to be deemed effective so that the plan can maximize reach at that level of frequency. The model can be traced back to his speech, "Effective Frequency" at an Advertising Research Foundation Key Issues workshop, June 4, 1982.

Typically, the model involves evaluating a series of relevant factors on a scale of say, 2 to 6, and averaging the factors to determine the appropriate level of frequency to set as effective.

In the 1982 speech the factors discussed were of three kinds: marketing, message / creative and media.

Marketing

  • Established brand vs new entry
  • Brand share
  • Brand loyalty
  • Purchase cycle
  • Usage cycle
  • Share of voice
  • Target group learning capacity

Message / Creative

  • Complexity
  • Uniqueness
  • New vs continuing campaign
  • Image building vs specific sell
  • Message variation (copy pool)
  • Wear out
  • Copy unit size/length

Media

  • Clutter
  • Editorial / program environment
  • Attentiveness
  • Continuity vs flighting
  • Number of different media
  • Repeat exposure opportunities
.

Guru(s), is effective frequency planning really dead? I have been reviewing the literature and it would seem that the concept of effective frequency is now outmoded and has been misinterpreted, over-simplified etc. I have been a proponent of the effective freq. approach in combination with ostrow model. I am loath to abandon, but don't want to be a media anachronism. Your thoughts would be much appreciated. (I have a presentation on Friday, during which I am sure to be grilled on the topic. R.

The Media Guru Answers(Thursday, January 18, 2001 ):
Effective frequency goals are apparently fading from favor in planning for products with continuous purchase patterns. There are sometimes good reasons, in time sensitive or highly seasonal categories, for example, to consider effective frequency. The distinction is a matter of professional judgement and assessment of marketing goals. This should outweigh planning trendiness, in the Guru's opinion.

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.

I'm working with fast food client in Puerto Rico(PR). PR is very competitive in this category. I like to know what is the effective frequency and reach in sustainning level and promotional period. I know that exist many theorical procedures to found the reach and frequency goals. But i'm very confuse what is the more accurate to this reality(very competitive environment)Please help me.

The Media Guru Answers(Saturday, April 29, 2000 ):
Competitive environment, e.g Share of Voice, is one key variable.

I would like to have information about typical rates of frequency that are considered necessary for advertising to be effective on different media. I would like information for television, radio, outdoor and print advertising. If there is such information, I would also like information for internet ads. In short, how many times does an ad need to be seen on different media before for an effective reach. Thank you...

The Media Guru Answers(Sunday, February 27, 2000 ):
Most judgements about effective frequency are just that; judgements. The traditional number, 3, is based on century-old learning theory about repetitions of information needed for learning to occur. This theory is not medium-specific but has many other aspects.

Research by DoubleClick about "banner burnout" shows that internet ads lose effectiveness (in the sense of causing clicks) by the third repetition. Of course, if you want to apply this approach to internet advertisng then you would be considering the awareness-building and sales-driving aspects of banners, rather than click-thru.

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.

Without the budget for post-flight call out surveys what formulas or 'rules' can I use to anticipate message saturation and burn. What reach or net reach level over what period of time would be probable to achieve a 80% awareness within the target. Also what is considered too much exposure for one message before you reach a point of diminishing returns. I know that the the better measurment here is research before and during the campaign, but there must be some bench marks that are industry accepted. Can you share these and share a public location for other general assumptions like this. Thank you in advance Guru... J

The Media Guru Answers(Wednesday, December 08, 1999 ):
  1. Ad awareness will never be greater than reach, so start from a plan that delivers at least 80% reach
  2. To establish measurable awareness, some repetiton will be needed, so think about getting an 80% reach at a set effective frequency level. The Guru has previously discussed use of the ostrow model to set this goal.
  3. A message is worn out when its ability to generate sales falls off. This being hard to predict, many advertisers have used past experience to set media-measurement based cut-offs. These have included a limit of 2000 GRPs and a frequency cap of 20 in the second highest quintile. In reality, the size of the copy pool, the qualities of the copy, the target, the overall media mix, and product category may all lead to wide variations in wear out. The two standards mentioned above were both commonly used in basic package goods TV advertising in a mix with print and a TV copy pool of 2-3 executions.

hi media guru please guide me : how can i know how much frequency, reach, and grp is needed for an old brand which first advertise on t.v? ( the target audience: main shoper with young children - 4-8 years old) thank you

The Media Guru Answers(Sunday, November 28, 1999 ):
This is a judgment call. The ostrow model can help guide setting of effective frequency goals.

Reach then becomes what you can afford or what you need in terms of numbers of sales to become successful judged against anticipated consumer response as a percentage of target consumers reached effectively.

Further, one must keep in mind, since you are writing from outside the U.S., that cultural situations and media environments have a big impact on the matter.

How does one set effective frequency and effective reach targets? Are there any models which can help set these targets? And is this approach(effective freq.) media neutral or does it apply differently to different media?

The Media Guru Answers(Thursday, October 07, 1999 ):
The ostrow model is one such model.

The concept of effective reach/frequency is based on repetition of messages as the key to consumer action, and so should be media neutral. However, since the nature of various media makes one generate higher frequency than another at the same reach level, plans often take different approaches to "effefctive." For example, a plan based on major magazine which average a 20 coverage among the target, will rarely generate even a 3 verage frequency in four weeks, while a radio plan for the same target might equal the magazine plan's reach in its first week and double the average frequency.

Planners work with the rules and rationales which make the most sense in a given situation.

Hi Guru, What exactly is the ostrow model ? How useful is it to the clients ? Is it the last word ? Thanks

The Media Guru Answers(Friday, September 03, 1999 ):
The ostrow model with which the Guru is familiar is a grid used to set the correct level of effective frequency at which plans will be evaluated.

20+ factors relating to competitive climate, product involvement, clutter, commercial length, commercial pool, etc are each rated on a scale, say from 2 to 6, which is then averaged to set the frequency level.

Is it the last word? Is it useful to clients? There is always another theory about anything. The usefulness is in creating a reational, well thought-through basis for establishing communiations goals, so that planners can present a logical approach to clients. The approach makes good sense, for those who follow the effective reach style of planning.

Dear Guru. I am a media planner in India. Need some information on latest effective frequency models. The ostrow model as described in the Scissors and Bumba is the only one I have seen. Are there any other models developed? Also it would nice if you could pass on some info on recency planning theory.

The Media Guru Answers(Monday, January 11, 1999 ):
The Advertising Research Foundation library would be the best source for alternative models.
