Where Google devastates other search engines is ability to get revenue from advertising.<p>Bing used to look like it had an ad load equivalent to Google but it was getting much less money per ad so Microsoft has really been running a charity. Today I see a very low ad load on Bing so I think Microsoft has given up on trying to look like they're successful at selling ads.<p>It would be quite possible to get better search results than Google today because the advertising gives them a powerful incentive to degrade the search results to train you to click on ads instead.
