I have wrote many times in this blog that Google is trying to take over the Internet world and that they are predominately a marketing and advertising company, not a search tool. Or maybe I should put it this way - they are a search tool but their search results are motivated by the highest bidder and not the quality of the result.
You already know that Google clear puts sponsored links and Adwords pages on your search results page. Fair enough, they have to get paid for their services and they deserve an income. Those areas are clearly marked so the user can decided whether to investigate those companies that showed up as a result of a search. My problem is that the rest of the search results, which are not labeled, are also a result of paid advertisers.
