Custom Event Tracking: WooCommerce Data Layer vs Shopify Pixel Limits
WooCommerce data layer supports all GA4 ecommerce events plus unlimited custom events with full parameter control. Datalayer for WooCommerce tracks 15+ standard events including add_to_wishlist, custom checkout steps, and parameters like billing address and order status not available in Shopify. Shopify Pixel Manager restricts stores to predefined events with no custom data layer access.
