First make sure your page is eligible for Facebook monetization. The main requirements usually include:
• Following Facebook Partner Monetization Policies
• Having original content (not reposted videos)
• Reaching the required engagement metrics (followers + watch time depending on the feature)
You can check your eligibility here:
Meta Creator Studio → Monetization Manager
It will show which features your page qualifies for (In-Stream Ads, Stars, Subscriptions, etc.).
If you’re not eligible yet, focus on posting consistent original video content and building engagement first.
