TokenTracker is a web service which issues electronic tokens - when you publish a post (or page) a token will get inserted into your post.

TokenTracker will then track where your tokens get syndicated on the web and generate analytics about where, when, who and unique visitors to your tokens.

The plugin will also assign any of the posts tags with the token - you'll then be able to see what tags are most popular.
