Tracing Facebook fan page "likes"

I wold like to find out how I can determine who is a zealot for my Facebook fan page.

I want to reward those individuals for going out on Facebook and encouraging people to become fans on my fan page. How can i determine how many people pressed the "Like" button because of Jon Doe's link and share posts on his Facebook account?

Hi,

It's not possible to see or know where your fans come from or send invites, since that info isn't available to page admins. You can, however, see if they have shared your posts by going on their profiles and checking their Wall tabs, in case they're visible to Everyone.
