Compete Says Bing's Combined U.S. Market Share Rose To 29% Last November

A couple of weeks ago, comScore came out with a report that said Microsoft’s Bing had reached an all-time high market share of 11.8% in November 2010.

According to rival Compete, however, Bing’s market share is actually much larger than that.

Based on search data from its panel of more than two million US-based internet users, the Kantar Media company says Bing-powered search engines as a whole grew 4.3 percent month-over-month in query volume, driving Bing’s total market share up by 1 percentage point.

Bing (‘MSFT’) and Yahoo’s search products (which are powered by Bing these days) had 14.4% and 14.6% market share, respectively, which means the combined market share of the search engines rose to a healthy 29% in November 2010, according to Compete’s search data. also saw the highest growth in the number of unique visitors, with a month-over-month increase of 7.4 percent (Yahoo’s number of UVs actually declined .3 percent). In November 2009, Bing’s market share was just over 10%, according to Compete.

Both ASK and AOL’s share remained flat from October 2010 to November 2010, which means there’s only one search engine whose market share effectively declined last November: Google‘s.

According to Compete, Google has seen its query volume decline for the second month in a row now, with a recent 1.1 percent month-over-month drop. Compete registered 66.4% market share for the search engine, down a noteworthy 7 percentage points compared to November 2009.
