Google Head Of Spam Confirms +1s and Likes Don't Increase PageRank
Posted: August 26, 2013 by Alex Chan
According to Moz, an SEO consulting company functioning since 2004, Google +1s and Facebook likes significantly influence the rankings of websites on Google's PageRank. However, according to the head of search spam at the Internet giant, Matt Cutts, this is not true at all.
In Hacker News, Cutts wrote a letter addressing Moz in regards to their latest story where they correlate Google +1s with RageRank. Cutts explained the matters very simply: correlation ! = causation. With this simple equation, he politely debunked the theory that Google relies on +1s in its page ranking. Cutts also went to remind webmasters of the similar situation back in 2011 when Moz released a statement that there was a significant correlation between Facebook likes and RageRank.
