Google is showing companies some social love.
This is because the search juggernaut has added social profile information to companies' Knowledge Graph results. According to Google's Zieb Ait Bahajji, this feature has been popping up in the search results recently, and now companies can use structured data markup on their official website in order to add their social profile information to the Knowledge Graph results.
It is important to note that companies can currently specify social profiles for Facebook, Twitter, Google+, Instagram, YouTube, LinkedIn and Myspace. To learn how to implement the structured markup, Web workers should visit Google's developer documentation for specifying their social profiles.
