Microsoft’s Bing.com has finally expanded it search to encompass Yahoo! organic results in the US and Canada. This increased Bings search market share to approximately28% overnight (depending on the statistics you look at). Starting in September 2010, Yahoo sponsor links will be transitioned to Bing adCenter.
Bing delivers more relevant results than than the ailing Yahoo engine and has a better Ad Center interface.
This is certainly a cause of concern for Google.
