Hi everyone,
I’ve been running UA + AdMob monetization tests for mobile apps/games and wanted to share a practical checklist that often improves revenue without changing the core product.


1) Ad formats & placement


  • Rewarded: place it on “high intent” moments (extra move, hint, skip timer).
  • Interstitial: limit frequency (e.g., every 2–4 completed levels / sessions), never on app start.
  • Banner: avoid covering key UI; consider adaptive banners only if it doesn’t hurt retention.

2) Mediation / bidding basics (if you use it)


  • If you use mediation, verify each network’s SDK version + test ads first.
  • Track fill rate + match rate separately (low match rate usually means poor demand or bad geo mix).

3) Geo strategy


  • Split campaigns by tiers (Tier-1 vs rest). Don’t mix everything in one bucket.
  • Compare eCPM per country and retention — high eCPM with terrible retention can still lose money.

4) App performance


  • Reduce ANR/crashes: revenue drops hard when stability is bad.
  • Keep loading screens short; optimize first session time.

5) A/B testing


  • Test one change at a time (placement, frequency, rewarded trigger).
  • Minimum 3–7 days per test per geo bucket.

If you share your app type (game / utility / webview) and top geos, I can suggest a simple test plan for placements & frequency caps.


Hope it helps.
