In June, 2007, people in the USA performed 8.0 billion searches, which was up 6 percent versus May of 2007 and up 26 percent versus June 2006.

Google’s web sites had a total of 4.0 billion search queries, Yahoo! had 2.0 billion, and Microsoft had 1.1 billion searches performed during June of 2007. The Ask Network had 403 million searches, and Time Warner Network had 341 million searches performed. That’s quite a lot of searches every month!

Other notable information is that Microsoft’s web sites experienced a significant increase in search query volume, which was up 36 percent and search market share, which was up 2.9 share points in June 2007, mainly due in part to the Live Search Club, a program launched by Microsoft in late May 2007 to engage and reward users of Microsoft’s Live Search.
