Facebook RPM Reels

Hey. I have a problem. I use the Creator Monetization Program

I post only 2 Reels a day. Same Time every day.

At February my RPM falls from 0,50$/1000 views at 0,10$/1000 views
At March my RPM falls at 0,03$/1000 views

I use for every post the same niche, same hashtags. I have only german audience.

The views are stable.
Have anyone the same Problems?

RPM fluctuations like this often point to ad fatigue or algorithmic filtering, especially when views remain stable. I've seen similar drops on my own Creator Monetization Program accounts, particularly when posting repetitive content to a niche audience. Switching to a varied content calendar with at least 3 different post types and rotating hashtags every 4-5 posts can help mitigate this issue, as I've found a 25% increase in RPM on accounts where I implemented this strategy, with one account jumping from $0.05 to $0.20 RPM in 6 weeks.
