Advertising Metrics and the Problem of Interpretation

One common metric used by marketers to evaluate advertising effectiveness is "recall". After their ads run with sufficient reach and frequency, research firms survey the target audience of the ads to see how many remember seeing/hearing the ad, its central message, etc.. If those numbers don't come in high enough, the usual response is to blame the advertising for being unmemorable and the agency for insufficient creativity.

That line of reasoning assumes that the advertising was seen and heard. In the age of the remote control, Tivo, impatient viewers, and proliferating commercials, that assumption is not tenable. The radio program may have 500,000 listeners, but how many sit through the six or seven or eight ads thrown at them during commercial breaks? The best ad in the world will look ineffective if it is slotted fifth in an eight spot block. Too many people will have zapped away.

Advertisers demand that their agencies "cut through the clutter" of competing ads. It is time that they look at media outlets and ask why they create clutter by putting together massive blocks of often insipid ads. While the eighth commercial does increase marginal revenue for the TV or radio station, it probably reduces the impact of the other ads.

Similarly, advertisers are going to have to come to grips with the impact of recording technology on viewership. It may be that technophiles are a lost cause for broadcast commercials. But advertisers can at least stop paying to "reach" an audience that is unreachable. NBC et. al. will not do the necessary analysis; that would take money out of their coffers. But any company serious about marketing ROI has to pay attention to this problem.
