Diagnosis checklist

Mobile game ad revenue diagnosis checklist

Small teams do not need another wall of metrics first. They need to know what changed first, which segment changed most, and what to inspect before making risky monetization changes.

Checklist

  1. Check impressions and requests before revenue.
  2. Compare match rate, fill rate, and show rate.
  3. Split by country / GEO before trusting blended eCPM.
  4. Split by format, ad unit, and placement.
  5. Check ad source or mediation source contribution.
  6. Compare time of day, holidays, live events, and seasonality.
  7. Add recent releases, SDK changes, floor changes, consent changes, and campaigns to the timeline.

How to read it

Output format

A useful diagnosis should say: revenue changed by X, the most likely driver is Y, the affected segment is Z, and the first check should be A. That is easier to act on than a dashboard screenshot.

Start with a before/after CSV and turn it into one diagnosis card.
