Beware the Advertising Pretest
It may seem odd that anybody would have a problem with pretesting an ad or marketing campaign. It’s hard to argue with the potentially money-saving (and mistake-preventing) insights research can provide. And in theory, pretesting makes total sense. The problem is that the science of advertising pretesting just isn’t there yet.
A few years back, Advertising Age ran a story about the uncertainties of ad testing. It cited Volkswagen’s («www.businessweek.com») popular 1997 “Da, Da, Da” Golf commercial, which some in Volkswagen management didn’t want produced. The article went on to say that a handful of Volkswagen commercials were evaluated using GM’s («www.businessweek.com») custom-designed pretesting system. According to the story, the successful VW commercials flunked under GM’s process. The Artificial World of Testing
Why can’t ad testing systems always predict real-world success? There are many reasons, but I believe they essentially boil down to this: It is impossible to replicate in a research situation how somebody will respond to an ad on a Sunday afternoon while sitting in their easy chair munching on nachos and watching the game.
When people are invited to participate in market research, whether it’s an online survey, a focus group, or even an in-home study, the circumstances will change the subjects’ behavior. They know they’re being watched, and they may even believe their job is to be critical. Respondents On the Hot Seat
Think about how a focus group works—people are invited in, fed a meal, and paid an incentive to offer insights and opinions that the sponsoring marketer can use. The pressure is on to contribute something of value. For someone to admit that they simply like an ad or to admit that it might influence them to buy something is rare. Instead, participants tend to understate how much they are affected by advertising and be overly critical of the ads themselves.
But the desire to contribute isn’t the only problem. Even if people in focus groups wanted to give an honest opinion, they may not be able to. People just aren’t able to articulate or even understand all the ways advertising affects them.
Marsha Lindsay, a graduate lecturer at the University of Wisconsin and a member of the executive committee of the American Association of Advertising Agencies, explains the problem this way: “Copy testing and other research based on explicit learning cannot accurately predict ads’ success because consumers can’t tell us ‘the truth’ about how ads affect them. That learning often lies buried in their subconscious.” The Shock of the New
Stanford psychologist Robert Zajonc suggests that the more people see the same thing, the more they like it—but that people often don’t initially like rare or unfamiliar things. Commenting on Zajonc’s research, Bruce Tait of Fallon Brand Consulting says, “If brands are to succeed, they need to be based on differentiated, unfamiliar brand strategies. Unfortunately, these are the exact same ideas that people initially dislike. That’s why quantitative testing of alternative positioning ideas will likely systematically kill the more original ideas, and people will prefer the ones that are closest to what they already know. The marketer using this type of test will unwittingly select the strategy that is less differentiated and eventually fail in the marketplace.”
By contrast, consider what the people behind some of the marketplace’s most successful—and beloved—advertising have to say. Scott Bedbury, the former worldwide advertising director at Nike («www.businessweek.com»), says, “We never pretested anything we did at Nike, none of the ads. [Dan] Wieden [the founder of and I had an agreement that as long as our hearts beat, we would never pretest a word of copy. It makes you dull. It makes you predictable.
