Americans conducted 6.4 bln searches in June 2006, a 6% decline from May 2006 (6.8 bln searches), but a 29-percent increase over June 2005 (5.0 bln searches), comScore says. The decline in search volume from May is considered to be mainly a seasonal effect. In June 2006, Google Sites led in search query volume with 2.9 bln searches conducted, followed by Yahoo! Sites (1.8 bln) and MSN-Microsoft Sites (818 mln). Google and Yahoo! continue to dominate the toolbar search market, combining for more than 95% of the market share in June. Google grabbed 49.6% of toolbar searches, while Yahoo! captured 46.1%.
Q2 2006 saw 19.9 bln searches conducted online, up 12% from Q1 2006 (17.7 bln searches), and up 30% from Q2 2005 (15.3 bln searches).
In Q2 2006, Google Sites registered the most search queries performed with 8.8 bln, followed by Yahoo! Sites (5.6 bln), and MSN-Microsoft (2.6 bln). Each of the major search engines has registered increases in search activity in Q2 2006 versus Q1 2006 and versus the corresponding period a year ago, with Google showing by far the greatest increase, followed by Yahoo and MSN.
