Google remained the top search site in June 2010, accounting for almost two-thirds (65.0%) share of all U.S. searches during the month, however, there was more significant movement among its closest competitors.
Although Yahoo (13.7% share of U.S. searches in June 2010) remained ahead of MSN/Windows Live/Bing (13.4%) the gap was less than half what it was in May 2010, when Yahoo! had 13.8% share compared to 13.0% for MSN/Windows Live/Bing.
Between them the top three engines account for 92.0% of all US searches in June 2010 – a slight increase from 91.8% the previous month. Factoring in AOL and Ask means the top five engines account for 96.1% market share – up from 95.9% in the previous month.
