comScore: Bing Search Share Sees Gains in November

Microsoft's Bing search engine continued to grow its share of U.S. searches in November, enjoying a 0.3 percentage point increase versus October, according to data from comScore. That gain appears to have come at the expense of Google, Yahoo, and AOL, all of which saw 0.1 percentage point reductions.

Though that growth is by no means exponential, Microsoft has been consistently growing its market share over the past year, accounting for 11.8 percent of searches in November 2010 versus 10.3 percent during the same month in 2009, and 11.1 percent of searches in August.
