Rewarded ads

Rewarded ads fill rate dropped

Rewarded ads often drive a large share of mobile game ad revenue. When fill rate drops, revenue can fall even if player activity and eCPM do not look terrible.

What to inspect

  1. Compare rewarded requests, fills, impressions, and show rate.
  2. Split by country because rewarded demand can differ sharply by GEO.
  3. Check whether placement exposure or reward flow changed.
  4. Review mediation source availability and waterfall / bidding status.
  5. Check timeout, load timing, and whether ads are ready when players ask.
  6. Compare app versions if a release changed the rewarded flow.

How to read it

Common interpretation

If requests are stable but fills drop, start with mediation, source availability, country mix, consent, and platform status. If fills are stable but impressions drop, inspect show rate and placement logic.

Separate fill-rate problems from show-rate problems before changing reward placement.
