Marketers need to become more aware of how they use content as ads. Content may become more important to search marketers, but a study from MediaBrix found 86% of U.S. Internet users feel they had been misled by video ads disguised as content. Some 85% said when they encounter these ads it either changed their opinion of the brand for the worse or had no effect. eMarketer points to the study identifying the problem, spanning from video to Twitter to Facebook.
