Which search engines get the most hits? According to comScore, Inc., a leader in measuring the digital use, in June 2010, Americans conducted 16.4 billion core searches, up 3% from May, with Goggle sites taking the lead with 62.6% of searches conducted.

Yahoo! sites (up 0.6 percentage points to 18.9%) came in second, and Microsoft sites (up 0.6 percentage points to 12.7%). Both Yahoo! sites and Microsoft sites have experienced gains due in part to the continued utilization of contextual search approaches that tie content and related search results together. Ask Network captured 3.6 % of the search market, followed by AOL LLC with 2.2%.
