shopify meta pixel double purchase events
The actual problem
Duplicate Purchase events inflate ROAS — you scale ads on fake conversions until real CAC blows up.
Do this
- Use Meta Test Events + order count for the same hour.
- Remove duplicate pixel / CAPI sources (theme + app + Shopify channel).
- Deduplicate with event_id on browser + server events.
- Re-baseline ROAS for 7 days before raising budgets.
