Matt Cutts, Head of the Webspam Team at Google, posted a short video to answer the question, “Are Facebook and Twitter Signals part of the ranking algorithm? How much do they matter?”.
He explained that if Google is able to crawl available information from Facebook and Twitter, then they are able to show it in search results. But as far as the effect of the number of followers in Twitter or likes in Facebook is concerned, it does not necessarily affect Google’s algorithm.
So a good reminder for Businesses and Marketers, Facebook and Twitter are still effective in distributing your content and the number of Likes and Followers will affect the reach of your posts but not the site’s ranking in Google.
(So stop buying likes and followers!lol)
“Facebook and Twitter are ways to drive traffic to your site, it’s a way to let people know about news related to you or your company or your website… but don’t necessarily assume that just because there’s a signal on Facebook or Twitter that Google is able to access that.”
Listen to Matt as he explained it further:
