You have probably already bought into the idea that social media matters to your business. If you haven’t you may just be living under a rock. For those of you who aren’t still living in the stone age and would like to gain a better understanding of how social interaction is having an impact on your business and website, please be sure to check out Social Plugin Tracking in Google Analytics from the official Google Analytics blog.
They explain how to track social interactions and how if you add the Google +1 button to your site and have the latest version of Google Analytics implemented, you will gain access to new Social reports from within the Visitors section of Analytics. Currently, the Social reports are broken into Engagement (what percent of your traffic is “socially” engaged), Action (e.g., have visitors clicked on your facebook “Like” button or the +1 button) and Pages (which pages did a visitor carry out a social interaction).
I believe these reports will give your business some new insights so if you haven’t already, make sure you have your site configured to capture all of these interactions.
