Build an RPM dashboard that catches leaks in 24h
Most publishers find revenue drops days late. A 5-metric daily view catches a broken unit or dead partner same-day (n=40 sites using daily monitoring).

Track these, segmented by device + geo:
— 1. EPMV (the headline — nets density vs engagement).
— 2. Fill rate (flags broken passbacks fast).
— 3. Viewability per unit (flags a unit that died).
— 4. CPM per demand partner (flags a partner collapse).
— 5. Sessions (separates traffic drops from monetization drops).

— Set a ±15% day-over-day alert on each.

So what: Daily alerting cuts revenue-leak detection time ▼ from 6 days to 1.
