Facebook/Twitter Use May Now Mean More for Google/Bing Rankings

[zaizaices8]

Google and Microsoft have both inked deals with Twitter and Microsoft has also inked one with Facebook to integrate Twitter and Facebook updates into Bing search results. Google will be adding tweets to search results.
Google's Marissa Mayer says, " We believe that our search results and user experience will greatly benefit from the inclusion of this up-to-the-minute data, and we look forward to having a product that showcases how tweets can make search better in the coming months. That way, the next time you search for something that can be aided by a real-time observation, say, snow conditions at your favorite ski resort, you'll find tweets from other users who are there and sharing the latest and greatest information."
