When it comes to measuring how content is shared across the Web, the approaches we use today are still pretty primitive. People count how many times a link is shared on Facebook or retweeted on Twitter, but nobody really knows what percentage of those links are clicked on to drive traffic back to the original sites. ShareThis , which offers an all-in-one share button across tens of thousands of sites, is trying to address this issue with new metrics across its network that measure not only how many times a link is shared, but also how many times people act on that and click back to the article or Webpage.
