Nielsen released its version of the U.S. search market rankings for July this week. Google is of course on top with 3 out of 5 searches (64.2%). Yahoo came in second with 14.3%, leaving Microsoft in third at 13.6%.

Yahoo and Microsoft both gained in month-over-month share (2% and 4%, respectively). This is all good for Microsoft, as Bing has now completely overtaken Yahoo’s organic results in the U.S. and Canada. We’ll see our first glimpse of how this is working out next month.

Do you think Microsoft and Yahoo combined can take on Google? Share your thoughts.

"In terms of a Year-on-Year comparison there has been little change in Google’s share but more significant movement amongst its closest competitors," says Nielsen. "MSN/Windows Live/Bing’s share has grown from 9.0% to 13.6% (a delta increase of 4.6% or a relative increase of 51%) while Yahoo!’s share has fallen from 17.1% to 14.3% (a delta drop of 2.8% or a relative drop of 17%). Consequently, over the last year Yahoo!’s delta lead over MSN/Windows Live/Bing has been reduced from 7.1% to only 0.7%."

Google, Yahoo, and Microsoft account for more than 9 out of 10 searches (92.1%).

The total number of searches in the U.S. over the last year has gone down by 16% from 10.5 billion to 8.8 billion. This is a very interesting stat. I wonder how much of this has to do with increased use of smartphones and mobile apps, taking the place of traditional searches. There are some other good points in the comments.
