comScore just came out with their February search report and Bing captured 11.5% of the search market, up from 11.3% in January and 10.7% in December and 8% last May.
In a similar pattern to prior months, Yahoo lost market share and Google maintained their market share.
If Bing’s market share continues to grow at a 2% month-over-month rate and Yahoo’s declines at at 2% month-over-month rate, Bing will overtake Yahoo by the end of this year and hold a 14% overall market share.
Of course, this is all based on comScore data, which doesn’t reflect what many sites show in terms of where their search traffic comes from, which typically is dominated by Google.
