Bing announced earlier this month that they have integrated Bing Connected Pages with Bing Webmaster Tools.
By doing this, you do not only have the ability to tie your social profiles to your Bing search profiles. But you also can see which social sites send you traffic. You can see which of your social profiles get how much search exposure in Bing. Bing will show you impression and click data to those profiles from Bing’s search results.
The social profiles included are Facebook, Twitter, LinkedIn, Google+, Windows Store, Google Play, Apple Store, Pinterest, Windows Phone Store, YouTube, Instagram, and MySpace.
