Does buying Facebook followers reduce your Page reach as a normal Page owner?

Buying followers doesn’t directly cause Facebook to punish your Page, but it can influence how the algorithm evaluates your content. Facebook measures how many of your followers actually interact with your posts. If you add a large number of followers who never react, share, or comment, your engagement rate drops. When that ratio becomes weaker, the algorithm may assume your content isn’t resonating with your audience and show it to fewer people.
This drop isn’t a penalty — it’s simply a mathematical effect. The more inactive followers you add, the harder it becomes for your posts to reach the same percentage of people. If you do decide to buy followers, you need to keep posting regularly, encourage real interactions, and maintain active engagement with your actual audience. When your engagement picks back up, your reach usually recovers over time.
