Google accounted for 65.02% of all US searches conducted in the four weeks ended June 2, 2012, according to Experian Marketing Services' Hitwise. Bing-powered search accounted for 28.12% of searches: Yahoo Search and Bing received 14.95% and 13.17%, respectively.

The remaining 65 search engines in the Hitwise Search Engine Analysis report accounted for 6.86% of US searches.

One-word searches constituted the majority of searches, amounting to 29.93% of queries. One-word search queries increased 19% from May 2011 to May 2012.

Longer search queries—five to seven words, and eight words or more—decreased 4% from April 2012 to May 2012, and some 11% from May 2011 to May 2012.

"As automated search features have rolled out across the major search engines, we can expect to see one-word searches continue to increase as they have over the past year," said Simon Bradstock, general manager of Experian Hitwise. "The long tail is not going away, [instead] becoming more intensified within the shorter queries."
