Yahoo Gains Search Market Share At Google's Expense-ComScore

Yahoo Inc. (YHOO) increased its share of the Internet search market in April compared with the previous month, mostly at the expense of sector giant Google Inc. (GOOG).

According to monthly data from comScore Inc. (SCOR), Google remained the market leader by a wide margin, powering 64.4% of U.S. searches. But its share fell 0.7 percentage point from March, while that of Yahoo rose 0.8 point to 17.7%. Microsoft Corp. (MSFT) increased its share of searches by 0.1 point to 11.8%.

Yahoo has been posting share gains as it begins to reap rewards from a search pact with Microsoft.

During the first quarter, Yahoo launched its 10-year revenue-sharing partnership. Under the pact, Microsoft's Bing will power searches on Yahoo's Web properties. And the Bing engine started chipping away at Google's broad lead after a splashy launch last summer.

Ask Network, owned by IAC/Interactive Corp. (IACI) captured 3.7%, followed by AOL Inc. (AOL) at 2.4%--both were down 0.1 point.
