Google, Yahoo gain search share

Google remains the sultan of search in the U.S., leaving even second-place search engine Yahoo in the dust, according to the comScore Networks monthly qSearch analysis. Meanwhile, despite heavily pushing its revamped Windows Live Search service, Microsoft lost ground in December.

Google captured 47.3 percent of the U.S. search market last month, gaining 0.4 share points from the previous month. Yahoo picked up 0.3 share points, giving it 28.5 percent of U.S. searches. Microsoft, meanwhile, dropped from 11 percent to 10.5. Ask Network holds just 5.4 percent; Time Warner Network holds 4.9 percent.

Translated into actual searches, Americans conducted 3.2 billion on Google; 1.9 billion through Yahoo; 713 million using MSN-Microsoft; 363 million on Ask; and 335 million with Time Warner Network.

All told, U.S. Internet users conducted 6.7 billion online searches last month, 30 percent more than the same period last year, according to comScore.
