June 2010 U.S. Search Engine Rankings from ComScore

The leader in measuring the digital world, comScore Inc., has just published its monthly US search engine market analysis covering the month of June. According to it, in June 2010 Google lost around 1.1% market share at the gain of both Yahoo! and Bing. Of course Google still remains number one search engine in the U.S. with 62.2% of the core searches conducted.

Yahoo! and Bing’s search shares accounted for only 18.9 % and 12.7 % respectively. However, unlike Google, both of the two Google’s rivals saw a small growth: Bing – up from a 12.1% in May to 12.7% in June; and Yahoo! – up from 18.3% in the previous month to 18.9%.

But no cause of alarm for Google, because all these figures are not adjusted for the changes introduced by Yahoo! and Bing. Their increase in market share was due to the utilization of contextual search approaches that link content and related search results together. ComScore explained it in its previous post.

In June 2010, Americans executed 16.4 billion searches, which is 3% increase over May. Total searches executed on Google Sites amounted to 10.3 billion, followed by Yahoo! Sites with 3.1 billion and Microsoft Sites with 2.1 billion.
