Facebook Share Adds Live Share Counts, Analytics
Along with the improved look of the Share Button, Facebook Share now offers publishers detailed analytics, allowing you to see how many times a link has been shared, as well as actions that occur on Facebook itself, like the number of comments and Likes it’s received as well as the number of times people have clicked on the link back to your site.
Apparently some of this data was already available to select partners, too: Facebook’s blog post notes that Techmeme has been using it to help select top stories, and link shorteners bit.ly and awe.sm for improved analytics.
You can find Facebook’s blog post, which includes details on implementing the new widget, here.
