Search result annotations:Bing now displays which search results your friends have liked. This is shown with annotations and small thumbnails under any link that your friends has liked.
Surfacing content from Likes: Let’s say Mashable or Cooks.com comes up in one of your searches, and your friends have liked specific articles or recipes from those websites. With Bing’s new Facebook integration, that content will surface right under the Mashable.com or Cooks.com search result. Bing says that this makes it easier to find the “good stuff” within core search.
Changes in search rankings:Facebook Likes now affect search rankings. An article that might have normally surfaced on the second or third page of search results may appear on the first page if friends have liked it.
