Bing failed to steal any more searches from Google in May 2011, halting eight straight months of search market share growth, according to the latest comScore figures. Here's a look at comScore's rankings, as well as U.S. search engine market share stats from Compete and Hitwise

comScore

  • Google search market share grew slightly to 65.5 percent (up from 65.4 percent in April).
  • Yahoo held steady at 15.9 percent.
  • Bing held steady at 14.1 percent.
  • Ask dropped to 2.9 percent (down from 3 percent).
  • AOL held steady at 1.5 percent.

The number of searches increased 5 percent compared to April, growing to 17 billion in May, up from 16.2 billion searches conducted in April. Google ranked first with 11.2 billion searches (up 5 percent vs. April); Yahoo had 2.7 billion searches (up 5 percent), Bing had 2.4 billion (up 4 percent), Ask Network had 502 million (up 2 percent), and AOL had 254 million (up 2 percent).

"Powered by" searches remained flat month-over-month, with Google powering 67.8 percent of all organic search results in May and Bing powering 26.5 percent of searches.

One note before looking at Hitwise's stats: these stats are for searches for the four weeks ending June 11, 2011. Also, Hitwise didn't put out an official news announcement comparing data to the prior four-week period. We plan to check with Hitwise to get this data and will update the post.

  • Google: 67.95 percent
  • Bing: 13.80 percent
  • Yahoo: 13.63 percent
  • Ask: 2.64 percent
  • AOL: 1.38 percent

The five most visited sites from search engines in this period were Facebook (8.65 percent); YouTube (4.71 percent); Gmail (3.02 percent); Google (1.35 percent); and Wikipedia (1.20 percent). Facebook received the largest percentage of visits (10.79 percent), with Google in second (9.13 percent), and YouTube third (3.80 percent).
