# Revenue Drop Checklist for Publishers

A sudden drop in revenue can be worrying. This checklist helps publishers quickly review the most common causes.

## Confirm Data and Time Frame

1. Check you are comparing the same date ranges.
2. Verify that filters for site, device, or geo are consistent.
3. Look at several days together to rule out a single outlier.

## Check Technical and Policy Factors

* Confirm that sites and ad units remain active and verified.
* Make sure no major layout or integration changes recently removed placements.
* Review any new policy or quality alerts that could affect serving.

## Review Traffic and Mix

* Compare site traffic before and after the drop.
* Use device and geo breakdowns to see if a specific segment changed.
* Contact support with details if you cannot identify a clear cause.
