If you haven’t created your own customized intro page for your Facebook business, install this app and follow the instructions: http://www.facebook.com/apps/application.php?id=190322544333196

Facebook has its own tracking report that Page users get once a week, but you can get a more detailed tracking report using Google Analytics. Follow this great tutorial at HyperArts to install Analytics tracking on your Facebook custom Page. The only thing I would add to the tutorial, is stay in “Old Version” (top right of your screen in Analytics) at least until you’ve created added your new Facebook profile.
