I did a post on my FB author page last night (2000+ subscribers) and 12 hours later it's had 30 views,
I call that good viewing stats for FB.
Facebook never shows more than 5% of the people who like your page anything posted on it.
Facebook for me is spread across 4 things. People who friended me, people who friended my father's old account, my Group, and my Page. I post the same thing in all of them, and people see one of them at some point.
I don't rely on it, but my FB fans are the ones who buy pre-orders as soon as they go up.
There's a lot of total crap being posted around about FB at the moment, and my expectation is in the long run, there won't be any change to FB at all.
FB stopped showing people Page posts at the same time they put the boost button on. That's old news. I have no doubt they play around with the algorithm still, and now it's being tweaked more than usual because of the current insanity going on.
