Overall, the range of visitors that are logged in to Google when finding these sites is typically between 15% and 25%. This is up from last year. Of course that number varries from site to site.
On Social Fresh for instance, over 50% of our visitors have been logged in to Google the last four months in a row! You are a savvy bunch of digital natives it seems.
This percentage is rising as a whole. And it will continue to rise.
Does this mean that about a fourth of all your visitors are using Google Plus? Not hardly.
