I am pretty certain FB minimized the reach of my page's posts

Does anyone know how and where I can check this? It’s a large page that in recent months is getting very limited exposure as if they closed the faucet or something. We haven’t been ghosted, we do have reach, it’s simply much much lower than normal even when the post is clearly good and should be getting a lot of attention.

Thanks.

This is for checking link ghosting but give it a shot anyway:

Thanks. We haven’t been ghosted, luckily we are not on that list. The reach is simply significantly lower than normal.
