how do I track serps for facebook page?

started a parasite page, been ranking it. How do I track all the long tails it might be picking up, etc?

Not sure if there's metrics in facebook to track google's serps? Obviously can't track it through WMT.
Is there any other way other than just going through thousands of LSI and longtails one by one to determine if my page is ranking anywhere?
