iProspect , Fredrick Marckini’s search engine marketing firm released a survey today which confirms that loyal users of Google and Yahoo! prefer organic search results over paid advertisements. No surprise here. What is more interesting is a shared characteristic of MSN and AOL: their ability to convince users that paid advertisements are as relevant as natural search results. Or is that so? What is more likely, of course, is that the way MSN and AOL show search results is not intuitive enough to enable the average user to distinguish between natural and paid results. Either way, the fact is that if you want to reach the audiences of AOL and MSN, pay-per-click programs Google AdWords which provides the sponsored search results for AOL, and Overture’s Pay for performance program which feeds ads to MSN, are as important as having your site optimized for natural search engine rankings.
