GA4 for Shopify: A Clean Tracking Setup You Can Trust

Attribution isn’t perfect, but it can be useful. The objective is consistent measurement of sessions, add-to-cart, checkout, and purchase—plus a way to validate that events fire correctly.

Baseline events to validate

• View item (product page)
• Add to cart
• Begin checkout
• Purchase (with revenue)

Common failure modes

• Duplicate purchase events (inflated revenue)
• Missing revenue parameters
• Cross-domain issues when using third-party checkout experiences

Validation workflow

1. Use a test product and run a complete purchase.
2. Confirm events in real-time reports and debug tools.
3. Mark purchase as a conversion only after validation.
