I have a Facebook page (not a personal page) and have only got 2 likes in a year. Not a very good track record!
sort by best latest
Since stats are unavailable for Facebook, I don't know whether anyone is even visiting my page. Also there is some anomaly where my avatar doesn't appear when I make a post or add a comment to other Facebook pages.
I do receive monthly stats but have the same problem when I try to post. I think it has to do with not having a personal page.
I gave my personal page administrator privileges over my "business" page and it sorted this problem. So now I can comment, share and post. (Must resist the urge to Spam!)
