Most likely driver
A directional read of whether the change started with traffic, fill, country mix, placement, source, timing, or pricing.
Free diagnosis
Apply for a free revenue-drop diagnosis.
Send anonymized report rows and separate the change into traffic, fill, country, placement, ad-source, time-of-day, and pricing signals.
No dashboard access. No SDK. No account credentials. The email builder is only the submission method; the point is a directional diagnosis of the revenue change.
Supporting signals
The report changes that support the interpretation, plus clear caveats when the supplied data is insufficient.
Three first checks
A short priority list to run before changing mediation, floors, or placement logic.
Team-ready explanation
A concise explanation you can share with your team, an ad platform, or a deeper monetization review.
Request builder
Diagnosis request details
Use approximate or anonymized values. The more structured the rows are, the easier it is to identify whether the drop starts from traffic, fill, pricing, placement, country mix, or ad source performance.
Good for
- AdMob revenue drops
- AppLovin MAX or mediation changes
- Fill-rate or match-rate drops
- Country mix changes
- Placement-level revenue changes
- One ad source suddenly losing volume

- Stable impressions with lower weighted eCPM
Minimum useful data
- At least two comparable report dates
- Preferably 14 or more dates for 7-day comparisons
- Revenue and impressions
- Country, placement, or ad-source segments when available
- Requests and fills for fill-rate diagnosis
