Google, Yahoo and Bing April 2010 market share was just announced by Comscore.com this week. According to them, “Google Sites led the U.S. core search market in April with 64.4 percent of the searches conducted, followed by Yahoo! Sites (up 0.8 percentage points to 17.7 percent), and Microsoft Sites (up 0.1 percentage points to 11.8 percent). Both Yahoo! Sites and Microsoft Sites have experienced gains due in part to the introduction of new site navigation experiences that tie content and related search results together within several channels. These features provide search results to users as they navigate through topical content and meet comScore’s established criteria for counting search queries. Ask Network captured 3.7 percent of the search market, followed by AOL LLC with 2.4 percent.” Click here to read the rest of their press release.
