Is there any way to reduce these clicks that are coming from no where? I find a lot of Facebook clicks gets registered but I don't see anything my side.
I would also get clicks from people from other countries when it shouldn't happen.
Is there any way to reduce this amount?
not unless you know this guy personally 
I get 20-30% click discrepancy on FB. Even worse when targeting international, just part of the FB game.
Don't know anyone who's been able to get around it, might be a good question to bring up for anyone who has a rep.
