U.S. Desktop search rankings from comScore came out. Google Sites led the U.S. explicit core search market in December with 63.8 percent market share, followed by Microsoft Sites with 21.1 percent (up 0.2 percentage points) and Yahoo Sites with 12.4 percent. Ask Network accounted for 1.6 percent of explicit core searches, followed by AOL, Inc. with 1 percent.*“Explicit Core Search” excludes contextually driven searches that do not reflect specific user intent to interact with the search results.
17.4 billion explicit core searches were conducted in December, with Google Sites ranking first with 11.1 billion. Microsoft Sites ranked second with 3.7 billion searches (up 1 percent), followed by Yahoo Sites with 2.2 billion, Ask Network with 279 million and AOL, Inc. with 178 million.
As indicated, the charts and data above don’t reflect mobile search volumes, which are probably relatively modest for Bing and Yahoo but quite significant for Google. The company said last year that mobile queries surpassed PC search volumes in numerous countries, including the US.
