Pricing changed. Check country mix, bidder/source performance, floors, seasonality, and mediation waterfall changes.

Supporting signals

Revenue: $206.73 -> $174.42 (-15.6%)
Impressions: 27,594 -> 28,398 (+2.9%)

Fill rate: 80.9% -> 82.1% (+1.5%)
Largest segment drop: Idle Ocean / Rewarded Home / US / AdMob

Recommended checks

Split eCPM by country, placement, and ad source to see whether the drop is concentrated.
Check mediation waterfall, bidding sources, floor rules, and recent pricing changes.
Compare against platform status, seasonality, and major demand-source budget shifts.

What to avoid

Avoid treating blended eCPM as proof of a global pricing issue before splitting by country, placement, and ad source.

Diagnosis logic

When impressions and fill are comparatively stable while revenue falls, weighted eCPM, demand, source performance, and traffic composition become stronger explanations.

Data limitations

This is a directional CSV diagnosis, not a final attribution from the ad platform.
If volume is low, eCPM and fill-rate movements can be noisy.
Avoid changing global floors or mediation settings before confirming the main segment.

Next action

Use the recommended checks first. If the report still cannot explain the change, prepare anonymized before/after rows for a directional diagnosis request.
