In the past five years FACEBOOK this become extremely greedy.
Us owners of a Facebook page,
we are at constant attack about us paying Facebook so this to deliver advertising benefits.
But FACEBOOK management this started
to deliberately SABOTAGE even our minimum visibility due it own search engine.
Additionally any posted content with hashtag older than a month
OR if this does not receiving 15 likes at least, this now stays as invisible.
Today I am officially opt out from such an piss poor mechanism. Google search this is not any better, there is active sabotage of Blogs and forums.
And therefore if you do seek alternative search engines?
