Is there a way to track who is visiting your facebook page?

Yeah you should get weekly reports, plus facebook also have some analytics that you can use for tracking visits. Another good way of tracking would be to use bit.ly urls in your status updates, It's pretty broad though as it only tracks clicks, so if one user clicks the same link more than once it'll still be tracked as two clicks. Never the less, Bit.ly has some nice analytics on site which can give you some info on amount of clicks, geographic locations, referrals and more. Just can't think of what they are off the top of my head.
