Check the identifier
Confirm the click URL contains the exact {CLICK_ID} macro and the tracker receives an expanded value. Store that value with the visit; without it, a postback cannot reliably attribute the event.
Check the event path
- Confirm the tracker fires the postback on an actual conversion.
- Inspect the destination URL and parameter mapping.
- Test with a real recorded click ID and inspect the response.
- Confirm event names, values, campaign selection and report date range.
If still missing
For pixels, verify that the conversion page and required consent allow the pixel to fire. Share redacted request and response details with support. Avoid treating zero reported conversions as proof of low-quality traffic until tracking is verified.
