Here is an interesting update on the use of Google+ and how it compares to other social media, coming from the Search Engine Journal.
By creating accounts automatically for all new users, Google has been accused of artificially boosting its Google+ numbers. The Wall Street Journal has even labelled it a “virtual ghost town”.
If you compare the average number of minutes per month a users spends on each social media, the gap is huge:
Facebook: 405 minutes
Pinterest/Tumblr: 98 minutes
Twitter: 21 minutes
Still, for SEO purposes, we still cannot ignore Google +.
