eCPM Bazaar helps mobile game and app developers diagnose ad revenue changes by splitting the movement into eCPM, impressions, fill rate, country, placement, and ad source performance.
The public demo supports sample data and browser-only CSV upload, then generates a short diagnosis explaining the most likely driver of the change.
- Diagnose ad revenue changes by eCPM, impressions, fill rate, country, placement, and ad source
- Browser-only public demo with built-in sample data
- CSV upload demo without storing or uploading user data
- Automatic comparison between latest day and previous day
- Short diagnosis summary explaining the most likely revenue driver
- Check why mobile game ad revenue dropped yesterday
- Separate eCPM drops from impression, fill rate, or traffic mix changes
- Compare monetization by country, placement, and ad source
- Sanity-check CSV ad monetization reports before changing mediation settings
- Help indie developers understand AdMob, AppLovin MAX, Unity LevelPlay, or TopOn report changes

I built eCPM Bazaar after seeing small mobile game teams spend too much time guessing why ad revenue moved. Most dashboards show numbers, but when revenue drops, developers still need to know whether the real driver is eCPM, impressions, fill rate, country mix, placement, or ad source performance. The current demo is intentionally simple: use sample data or upload a CSV in the browser, compare the latest day with the previous day, and get a short diagnosis. No data is uploaded or stored. I am looking for feedback from indie game and app developers who monetize with ads.
