Bing and Yahoo are the same search engine now. You probably don't know, but Yahoo uses Bing to give you results. So they have about 30% of search marketshare at this point, compared to Googles 66%.
Bing is a lot bigger than most people realize.

People talk about Google taking Microsofts marketshare in laptops with android and free office...but MS is going for the ONLY marketshare Google makes money on...search. And Google has lost 7% marketshare in the last 12 months.
They just changed their CEO too...just saying.
As far as the OP, I don't know enough about search and the algorythms at play...and I don't want to sound retarded like some people above by pretending like I do know, so Ill keep quiet.
