i have page with 150k and almost every post i post is over 50k.. so faceboo has done nothing to the reach.. the thing is most of you people polute your posts with monetization... posting all sorts of crap which kills the engagement.. its about timing on what you post. My last 30 posts have all been over 50k, some as much as 130k.. so i know for a fact it isnt them killing the reach. Some of you post too much.. i could go on with how i post but im not gonna write paragraphs.. just minimize the monetization until you have the page engaged.. 10k for 500k is insane.. i post and like 3 mins after reach is already at 5k..
