All the major search engines are now working on integrating signals from your own personal network on sites like Facebook and Twitter to enhance their search results. Google launched its latest initiative last week and today Bing is launching the next step in its program to bring more “liked results” to its results pages. Whenever one of you friends has liked a page that appears in your search results on Microsoft’s search engine, this fact is now highlighted on Bing and your friends’ profile pictures will appear underneath the link.

Bing already featured some Facebook likes on its pages before, but these results were still limited to a selection of sites that were whitelisted by Bing and results appeared in their own box at the top of the search results. Today’s update brings “liked results” to any page on the Web that one of your friends has liked in the past.

Unlike Google, Bing doesn’t surface any shared links from Twitter. Google, on the other hand, doesn’t show any Facebook ‘likes’ yet.

It doesn’t look as if Bing is using these signals to influence what links you see in its algorithmically determined search results, though. Depending on how much you trust your friends’ recommendations, that is either a good or a bad thing, but chances are that Microsoft is also working on making social recommendations one of the (infamous) 1,000 signals Bing looks at to determine search relevancy.
