Here’s a screenshot of some recent visitors to my blog, with detailed info about one of the visitors:
Just click on one of the map location markers to see useful information about that visitor. How long they stayed, where they came from, which pages they looked at, what browser, screen resolution, etc.
You can get all this information already by choosing the relevant option from the StatCounter menu. But seeing it all displayed together on a Google map is even better.
A very cool feature!
