It’s official: Yahoo search is now powered by Microsoft’s Bing, the end result of a deal signed a little over one year ago by the two companies.

That means that combined, Microsoft now owns 28.1% of the search market (as of July 2010’s comScore numbers), though that’s still less than half of Google’s 65.8% share.

AdSense for content publishers, who make up the vast majority of our AdSense publishers, earn a 68% revenue share worldwide. This means we pay 68% of the revenue that we collect from advertisers for AdSense for content ads that appear on your sites.
