Recall is an important indicator as it often correlated with efficiency Recalling an ad is considered a necessary (but not sufficient) condition for further effectiveness Recall Millward Brown identifies a clear-cut relation between highly recalled campaigns and their subsequent sales effectiveness
The Beta ( β ) coefficient is an accepted measure to assess recall of a media Developped in the 70’s by A. Morgensztern Beta = probability of recalling a given ad after 1 contact, based on post-tests Beta coefficient What is this ? Forecasts the « recalling power » of a media ‘ beta’ measures exists for different media: impact comparison possible Benchmark Why is it used ?

Establishing a beta value for DM Average DM beta value = 67,4% out of 89 cases (DM Barometer post-tests, B2C) After one DM campaign 2 out of 3 exposed consumers are likely to recall the advertised brand
Beta value* per category Campaign recall % per category Avg= 67,4% * « Business to consumer » value
Beta value* per DB type Avg= 67,4% Campaign recall % per type database * « Business to consumer » value (= prospection) (= loyalty, upgrade; prospection on own data)

From recall to Beta coefficient Developped in the 70’s by A. Morgensztern Beta = probability of recalling a given ad after 1 contact, reconstructed, based on post-tests Beta coefficient Recall after 1 contact determines recall after « n » contacts Beta may be used as a model parameter for recall building and decay Source:
Beta = source for modelling recall Recall build-in End active period
From campaign to medium Principally, each campaign has its own strength (= beta). As a forecasting tool average beta value is often derived per medium Average beta per medium + It allows intermedia comparisons (see further) - Not every campaign has the « average » Impact value Source:
BETA DM: assumptions Average beta coefficient DM Based on recall as given by the post campaign measurements * Frequency considered equal to 1 * No decay factored since the first exposure * Averaged across target groups * Same assumptions as in France (see further) Source:
