I’ve 3Million reach on my 270K page. I’ve many pages with good likes and reach…
TO whole I’ve understood in these 2 years: You need to post images and shares video regularly on yours. The links would kill the page if it is only posted.
Or if you post a tech related links on a Facebook page which is on entertainment; movies. The reach would be negligible
Another thing, if you stopped updating a page completely for like several months, it won’t pick up reach easily anymore
