Question wrote at Wednesday, May 21, 2003 #5979: We’ve done an AdAwareness modeling and planning for 8 markets. And we require to do projection for other dozens of markets. The objective is to define the budget setting of each market based on our models. What’s the best approach we should look at? The Media Guru Answers(Saturday, May 24, 2003 ): It is not clear what the result of your "Awareness modeling" is. Does your model give you the weight to deliver by medium? In that case, you just need access to media costs by market. If not, your query needs clarification. The Awareness Modeling gave us the response function and we can do prediction based on the parameters we found (short/long term effect, decay, etc.) Up to now the awareness planning will help us to identify how much weight we need to get certain level of adawareness, and vice versa, how much adawareness we can get with our media weight. We're still consentrating in the aided TV adawareness modeling. The question is, how can we apply our modeling (8 markets) to any other market. As far as we understand, the response function and awareness modeling itself are applied only for the tracked Market respectively. Is there any successful case study for applying awareness modeling into other market which has no historical awareness data?

The Media Guru Answers(Monday, June 02, 2003 ):
If you define your model as not applicable to other markets, you leave yourself with no options.

Dear Guru: I have seen the terms "adstock" and "half life" mentioned a number of times, but I did not find any staightforward definitions of these term. Will appreciate your help.

The Media Guru Answers(Monday, February 03, 2003 ):
The Guru does not recognize either as media terms. The actual term "half life" refers to the time it takes half of the radioactivity in a radioactive object to decay. The Guru is not aware of this term as a standard media usage, though it might be applied to something like awareness decline after advertising stops.

What does the term "half life" mean and how is it calculated?

I am fitting curves on decay data. It was suggested to me to use a beta-binomial distribution as a fit. It's not available in SPSS: where can I get some [free] software? Also, can you give me a layman's description? Also, what does it look like?

The Media Guru Answers(Monday, February 04, 2002 ):
The Guru doubts ther is such software available for free. You need software such as that offered by Telmar.

The calculation is extremely complex. Click here to see an example of the math of the Beta-binomial function. There are variants of this formula, which might be preferred, depending on media type and other variables

What is the typical awareness decay when advertising goes off air? Specifically, we have been running a campaign since April, 2000 consisting of Cable TV, Print, Internet, and some guerilla media. The current total plan delivers 75/15.2/1138 against A12-24.

The Media Guru Answers(Thursday, November 02, 2000 ):
One theory says each weeks awarness is about 90% of the prior weeks' when there is no advertising. Of course one would expect this to vary depending on other advertising in the market, how high awareness had risen, current share of market, etc.

Hi Guru. Do you have any information about "decay Reach" or "decayed Reach"? My client asked me about it. I know "decay GRP" but I've never heard of "decay Reach". Does reach decay? Is it a popular concept?

The Media Guru Answers(Sunday, October 08, 2000 ):
This is not a familiar term to the Guru. It might refer to awareness decline after consumers are reached.

Dear Guru, we are getting into awareness based media planning which means objective will be set on awareness scores, rather than GRP, R&F. Please tell me the factors which are required and procedure for setting awareness objectives.Thank you

The Media Guru Answers(Friday, September 01, 2000 ):
Very theoretical. There is no specific rule of thumb equating awareness to GRP. There will be a big difference in saying the objective is to achieve 30% brand awareness versus increasing an existing awarness of 30% by 30 points.

You should think about:

  • What percent of "aware" persons will be purchasers?
  • What number of purchases is the pay-out level of your advertising?
  • How often does the aware person make a purchase decision?
  • Assuming awareness never exceeds reach, what reach must you acheive and what decay rate can your afford to maintain the awareness that will drive sales?

Frankly the Guru believes that saying "awareness based media planning" is just putting a marketing spin on the media plan. Ultimately a media plan sophisticated enought to have objectives almost invariably has some awareness objective mentioned. And ultimately, media must be bought in terms of GRP or impressions or insertions; the media vendors do not sell quantities of awareness. So either you have a formula which equates awareness numbers to media units or you do not. The Guru does not.

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.

Dear Media Guru I am a media planner from Pakistan.I need to ask what are the possible comparison tools that we can use while planning for different programs on television.At the moment while planning i calculate cost index, rating index, efficiency index, Avg GRP's, Maximum reach, and avg.viewing miniutes for each time slot. Normally i advertise in time slots with high effeciency index, is this a good comparrison tool for planning or not. Normally the decay factor that i take is 10% is this OK or not. What are the different possible ways to break the adverising clutter on television and increase the possibility of high ad exposure. Thax in anticipation Sarwar Khan Media Manager R-Lintas (Pvt.)ltd.

The Media Guru Answers(Saturday, July 29, 2000 ):
It always fascinates the Guru that countries sharing a common language can use it quite differently when applying it to the jargon of a particular business or interest.

What you are describing as "planning" seems to the Guru to be what he would regard as a buyer's selecting a schedule after a plan has been approved. You haven't mentioned what goals you are pursuing with your schedules. Selecting spots with the best efficiency index (audience versus cost) will get you the greatest total number of impressions, but possibly not the greatest net reach. The best rating is more often likely to lead to high reach, but perhaps not without due regard to efficiency and duplication.

"decay factor" is an unfamiliar term to the Guru. "Maximum reach" and "average viewing minutes" don't seem relevant to assessing individual spots as the Guru understands the terms.

Overall, the Guru believes you should be comparing possible schedules, rather than individual spots to accomplish planning goals.

Optimizers serve this purpose, but running reach analyses of several schedules can get you there, as well.

Dear Guru, Is there any literature on Advertising decay... more specifically - on the wearout of TVCs - and when is an 'optimal' time to replace them. I would assume that the above is a function of a host of subjective parameters - copy, message, audience profile, etc... but are there any studies / models you could suggest as a starting point ?

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.
