When we talk about search engines. we always say Google is the best. But since January 2011 Google Search market share is dropping off. If you see chart below in June 2011 Google picked Up its search market share. Ofcourse remaining search engine market shares decreased by some points.
Bing Search Engine is making a try to become a competitive to Google if we see from last few months.
Can Bing can make this Up in July wait and See.
