I have a mobile game app with 5 distinct game modes (Ludo, Tetris, Sudoku, Wordsearch, Jigsaw). My current AdMob Match Rate is low (~34%), and I need an expert to fix my fill rate and revenue without touching the code. The Setup: Ad Units: I have separate Ad Units for Rewards/Interstitials for different games. Constraint: You will NOT get access to the source code. You must work entirely within the AdMob Dashboard. Your Tasks: Fix Match Rate: It is currently bleeding revenue. Implement Mediation Groups (Unity, Meta, etc.) to ensure 90%+ fill rate. Granular Optimization: Set specific eCPM floors for "High Duration" games (Sudoku) vs "Fast" games (Ludo). Audit: Verify that my ad unit mapping is correct and identify any policy risks. To Apply: Tell me one specific strategy you use to optimize eCPM for a multi-game app vs a single game app.
