I have one million likes on my page. But my posts are reaching between 20k to 50k people. Maximum of 1k likes per post. In the other hand, I am seeing other pages with same amount of likes and they're receiving more than 20k likes per post and tons of shares. Their reach seems to be awesome. Why do I have that low reach? What the other pages are doing different? My page was never considered as "dead", I have always posted content into it. I never spammed with my page, I never even posted external links! I just don't get it.
