Perhaps more to the point. There’s basically no such thing as a “best result” for a search, and indeed all of our research is telling us that Google is moving away from even trying to produce “accurate” results. It’s been a long time since Google even allowed a proper Boolean search. With the introduction of Google Chrome and the statistics they have gathered from the pervasive use of Google Analytics we expect that they have already begun to bias results towards websites that have high Time on Site numbers.

Google’s rationale is simple… if people are spending a lot of time on the websites that Google ranks, they must be happy with the website, and that’s a good enough result for Google’s business model.
