Your Shopify Checkout is Stealing Credit from Your Best Campaigns
You check your GA4 landing page report. Something's wrong. 40% of your purchases are attributed to "checkout.shopify.com / referral" instead of your Facebook ads, Google campaigns, or email sequences.
Your best campaigns look like failures. Your actual winners are invisible.

Why this happens
Shopify uses a separate checkout domain (checkout.shopify.com). When customers proceed to checkout, GA4 treats it as a new session. The original landing page loses all credit. Your $5,000 Facebook campaign that drove the sale? GA4 thinks the checkout page did it.
😰 Is this your only tracking issue?
This is just 1 of 40+ ways UTM tracking breaks. Most marketing teams have 8-12 critical issues they don't know about.

The 3-minute fix
This uses GA4's cross-domain measurement to maintain session continuity across Shopify's checkout domain.
Step 1: In GA4, go to Admin → Data Streams → Web → Configure tag settings → Configure your domains
Add these three domains:
yourstore.comyourstore.myshopify.comcheckout.shopify.com
Step 2: Same location → List unwanted referrals
Add:
checkout.shopify.comyourstore.myshopify.com
Step 3: Test with a real purchase. Check GA4 real-time report. Your original landing page should now get credit.
What you'll see
Checkout URLs disappear from landing page reports. Purchases correctly attributed to Facebook, Google, email—wherever they actually came from. You finally see which campaigns drive real revenue.

FAQ
Will this fix historical data?
No, only future tracking. But new purchases will show accurate attribution immediately.
Do I need Shopify Plus?
No. This works for all Shopify plans.
What about Shop Pay?
Covered by the checkout.shopify.com domain configuration.
How do I verify it's working?
Make a test purchase from a UTM-tagged URL. Check GA4 to confirm the original landing page gets credit, not the checkout URL.
