Microsoft announced that Facebook Likes will have some effect on rankings for Bing. The goal of the search engine is to create more personalized search results. Search Engine Land reported that Microsoft is being somewhat cautious in rolling out that social media influenced rankings.
Facebook Like Content As Search Result
Already, Bing has included Likes within it's results as social media type content. Bing refers to this content as "Liked results" or “Liked By Your Friends.” In order for this feature to work, a user would have to connect Bing to Facebook. The results will populate with data from your immediate social network. Shared content is not included in this feature.
