11:08 · Seen
NadiaEach conversion in the plan was triggered in production, and the hits were checked against GA4, Meta and Google Ads, before and after consent. The discrepancies are listed, with network capture.
Scenario 3 · Discrepancy with the back-office
Nadia
Live
You : Why do our GA4 transactions differ from the back-office?
14:26 · Seen
NadiaI compare the back-office export and GA4, then trace the chain: triggering, consent, duplicates, cross-domain. Each probable cause is linked to a criterion in the grid and its fix.
