I’ve been noticing the results in Yahoo and Bing from my clients’ ranking reports showing very similar ranking placement for almost all keyword phrases we are targeting. They seem to be getting closer and closer together in the past two months. It’s been a slow progression, but this week seems almost exact except for a few standard variations.
Neither engine appears to be taking on the others’ exact rankings, but rather a marriage of both sets of algorithms have come together to make one happy search engine (at least happy with most of my clients). It looks like there are just two big players in the game at this time.
