Not every visit to your link can or should generate earnings.
Common reasons
- No campaign currently matches the visitor's country or device.
- The visitor already reached that campaign's frequency limit.
- The campaign reached a daily or lifetime cap.
- The campaign ran out of available budget.
- The visitor left before the required viewing period completed.
- The browser tab was hidden or the ad was not actually visible.
- The traffic triggered fraud or quality controls.
Ordinary non-qualifying repeat traffic is not necessarily fraud; it may simply be non-billable.
