Fred Marckini goes into greater detail about a study iProspect did with WebSurveyor on organic and paid search marketing. It found that natural search results were deemed the most relevant by users, but that the choice depended on both search engine and, surprisingly, demographics. He suggests that the observation, pending more research and a fit with an individual brand's target, may suggest search engine marketing campaigns could benefit from regearing to the more susceptible demographics.
