shopify loses utm parameters at checkout

The actual problem

Attribution breaks when UTMs drop before purchase, so teams scale the wrong campaigns.

Do this

1. Place a test order from an ad URL; confirm UTMs in order notes/analytics.
2. Fix theme scripts that wipe query params on cart/checkout transitions.
3. Prefer first-party landing params stored in cart attributes.
4. Don’t raise budgets until paid conversion attribution is trustworthy.
