In the past four weeks, Google has accounted for 66.69 percent of all US searches and Bing-powered searches accounted for 28.48 percent in that same period, according to Experian® Hitwise®.
The Big / Yahoo search market breakdown:
- Bing represents: 13.49 percent search market share
- Yahoo represents: 14.99 percent search market share
This data shows that Yahoo and Bing have received the biggest gains for February 2011. In this same period, long search queries decreased by 2% from January to February 2011, whereas one-word search queries increased by 2% for that same period.



Although Google is not incorporating Facebook Like activity into their search results, Bing has taken that step to introduce Facebook Like data to it’s pages. Some question whether Google can even get the Like data even though it does have a partnership deal with Facebook, allowing it to use the social data.
