FAQ

Common questions

Why clear the ecommerce object before each push?

+

GTM merges new dataLayer pushes into existing ones. Without the clear, items from an earlier view_item can leak into the next add_to_cart.

Should I use recommended or custom events?

+

Recommended events like purchase and generate_lead fill GA4's built-in reports automatically. Use a custom event only when no recommended event describes the action.

Where does the code go?

+

On the page where the action happens, fired at the moment it happens: on the order confirmation for purchase, and on a successful form submit for generate_lead.
