Google +1’s Amazing Correlation with Higher Search Rankings

Every two years, Moz runs a scientific correlation study to discover the qualities of web pages that have a strong association with ranking highly in Google. This year, for the first time, Dr. Matt Peters and the Moz Data Science Team measured the correlation between Google +1s and higher rankings.

The results were surprising.

After Page Authority, a URL’s number of Google +1s is more highly correlated with search rankings than any other factor. In fact, the correlation of Google +1s beat out other well known metrics including linking root domains, Facebook shares, and even keyword usage.

Moz isn’t the only one to discover this relationship. Searchmetrics, using a slightly different methodology, found Google +1s to be the highest-correlated factor they studied, and other studies have found similar results.

Here’s the million-dollar question: Can Google+ activity actually help your pages rank higher?
