shopify checkout loses utm attribution
UTMs dying between landing and thank-you make paid look worse than it is. Persist params through cart, then re-check ROAS before cutting spend.
The actual problem
UTMs die between landing and thank-you, so paid channels look worse than they are — bad budget cuts follow.
Do this
- Trace a test click with UTMs through ATC → checkout → order.
- Persist UTMs in cart attributes / customer notes if theme drops them.
- Compare Meta/Google reported purchases vs Shopify orders tagged.
- Don’t cut spend on ‘zero ROAS’ until attribution path is verified.
