Across the GetSocial Analytics product you'll often find the word Recirculation.
Recirculation measures the percentage of website visitors who visited a page and then visited another page, within the same session. It’s a simple yet extremely valuable metric for publishers, as it helps understand user loyalty.
The picture above illustrates the concept. In it, 100 sessions start on a specific page, coming from Facebook (referrals).
If 20 of those sessions end up visiting any new article, the recirculation % of that article was 20%.
