So, the psychologists have a better grip on their theories, and advertisers have a few things to consider. The first is that banner ads may provide a valuable function in fostering familiarity even if those that view them never click through to the source of the ads. The downside for advertisers is that any evaluation of the positive impressions that this familiarity creates, even one based on false premises, is enough to make those positive feelings vanish. This suggests that familiarity-based advertising may work best for impulse buys, where more detailed evaluations aren't likely to occur. More importantly, this gives us a glimpse into the way our unconscious works with visual stimuli.
