Yahoo!The Yahoo/Bing “merger” has happened within the past two weeks in the US and Canada. Searches on both Yahoo and Bing are now powered by Bing’s index and pay per click (PPC) results on both will be combined soon. Both companies see this as a big deal, especially in terms of helping them compete with search goliath Google, which still gets about 70% of all searches.

BingThis doesn’t, however, mean that results on Bing and Yahoo will be identical. While both are using the same index (the list of pages on the web with information about their content and linking), the two search engines maintain different algorithms. That means that different ranking factors are being weighed more or less heavily by each of them.

We can expect rankings in Bing and Yahoo to resemble one another more closely than they used to, but our client rank checking shows they’re still quite different.
