Google has rolled out an update to their search results display by “blending” social results throughout normal search engine result pages. Social Circle results were appearing at the bottom of results, however they are now displaying throughout the top ten positions.
If your friend shared a link on Twitter and that page appears within your search results, their name will appear underneath that listing. It will display their Twitter profile picture, their name and the words “shared this”. E.g. Jacqui Jones shared this
Google’s algorithm now takes into account results from a social perspective. Even though Google is keeping the specifics of how social activity affects search results, there is speculation that the more frequently a URL is “shared”, the higher it will move up within rankings.
It’s important to note that Google’s Social Circle feature has been fully rolled out in the United States. It is still yet to be released in Australia and other parts of the world.
