A new study suggests that marketers shouldn't fixate on the number of people who click on ads. According to the research, just seeing an ad on a Web page can impact memory. The findings could have a significant impact on the way online advertising is made and metered.Typically, to be considered effective, an online advertisement has to elicit a response--usually a click of the mouse--from a potential customer. But Chan Yun Yoo, an assistant professor at the University of Kentucky's School of Journalism and Telecommunications, found that when people view Web advertisements, they store information in two different types of memory: explicit and implicit.
Explicit memory involves facts learned through conscious interaction, while implicit memory involves unconscious retention. Explicitly remembered information includes ad slogans, product benefits, and website addresses. In contrast, implicit memory might only come into play when external stimuli trigger concepts. For instance, a consumer might only recall a brand of toothpaste from a television ad when he or she discovers it while browsing in a store. Or the consumer might develop an unconscious affinity for a certain brand despite not knowing specific facts about it.
Subjects who paid attention to a banner advertisement were more likely than those who didn't to recall whole words and facts from the ad--facts stored in explicit memory. All ads had the same level of impact in the unconscious explicit memory, however, whether or not they'd been clicked. Yoo's findings are relevant because they challenge the assumption that online advertising is only effective when it gets a direct response from the viewer. His study was published in the spring 2007 edition of Journalism and Mass Communication Quarterly.
