Organic reach on Facebook pages – still possible?

Post Reels to the FB page.

For me its going fire, but im in a easy niche.

I also encountered the same thing. There was a page before that posted about 5-10k reach, but now when I diligently post, I barely get a few hundred. But one day, when I posted exactly what a customer needed, one person suddenly shared it with the other, reaching tens of thousands without making any money. So maybe Facebook is really difficult now, but not to the point where if you don't boost it you'll "die"
