Outcome of Bing
 

I have seen the rankings of Indian site keywords in Bing and the rankings in Bing and Yahoo are similar as they are together. I think Yahoo is giving Bing�s result. This I think has come to effect on Mid-September 2011. But there are different rankings of Bing and Yahoo in USA. In order to check the ranking of Bing I have gone to advance search and selected USA country and have given loc: US in search box in Bing. I do not know whether this is a better or right option or not. The ranking of Yahoo and Bing are almost the same but it depends upon the place from where you are searching.

Normally you are getting same results from yahoo and bing but when you select a specific region then its ranking will be different.

I have also noticed that but don't have any idea why this happens.
