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.

BigQuery Direct: WooCommerce Sends Data Free While Shopify Locks It

WooCommerce enables direct BigQuery data streaming at any price tier through server-side exports, MySQL exports, or tools like Transmute Engine ($89-259/month). Shopify locks native BigQuery integration behind Shopify Plus at $2,000+/month, or forces third-party connectors costing $100-500/month. For store owners prioritizing AI-readiness and advanced analytics, platform choice determines whether data warehouse access costs $99/month or $2,500/month.
