Brafton recently reported that Yahoo and Bing are gaining ground in paid search since the adCenter transition, but Google still holds the lion’s share of the search market. The latest report from comScore shows that Google came out on top at the end of 2010.

The December 2010 search engine rankings show that Google’s share of explicit and total core search queries rose 3 percent last month. Americans conducted 18.2 billion total core searches in December, and Google fielded more than 11.7 billion of these queries.

The company held steady at 64.3 percent of the total core search market, but it demonstrated gains in the explicit core search market, reaching 66.6 percent share.

Microsoft sites, on the other hand, saw moderate gains in both search markets, accounting for 12 percent of both explicit and total core searches. Bing’s gains were tempered by Yahoo’s losses, though the company is still No. 2 in the search market, accounting for 16 and 18.8 percent of explicit and total core searches, respectively.

Google’s dominance is confirmed by the latest search ranking report from another analytics leader, Experian Hitwise. Hitwise data suggests that Google lost some market share to Bing-powered search, but it still places the company solidly in first place, representing 69.67 percent of the market.
