According to Nielsen data out this morning Microsoft’s Bing has passed Yahoo to become the number two search engine in the US. Nielsen says that Google’s August share is 65% (and growth is flat) but that Bing and Yahoo have now switched places:
Although Google saw little change in its month-over-month search volume, it still dominates the search market, accounting for 65% of all U.S. searches. Yahoo! followed Google and MSN/Windows Live/Bing Search with a 13.1% share of U.S. searches, falling from a 14.6% share in July 2010 to 13.1% (a 1.2% delta decrease or an 8% relative decrease).
In terms of a year-over-year comparison, Google has seen little change in its share of search while Yahoo! has seen a small but steady decline, going from a 16% share to 13.1% (a delta drop of 2.9% or a relative drop of 18%). MSN/Windows Live/Bing’s share has grown from 10.7% in August 2009 to 13.9% (a delta increase of 3.2% or a relative increase of 30%).
