A properly designed ecommerce data layer is the backbone of all GA4 tracking. It's the structured JavaScript object that makes product information, cart contents, and transaction data available to GTM — allowing tags to fire with accurate, complete data without scraping page content. Our data layer setup service designs a schema tailored to your store's product catalogue and checkout flow, implements it across all relevant pages, and documents everything so your team can maintain it.

Frequently Asked Questions

Without a data layer, GTM must scrape product information from the page DOM — which is fragile and breaks with design changes. A data layer provides structured, reliable data that persists across site updates.
For platforms like Shopify and WooCommerce, we implement it ourselves. For custom stores, we provide complete technical specifications for your developer and review their implementation before go-live.
We follow GA4's recommended ecommerce data layer structure — events pushed as objects with an 'event' key and 'ecommerce' object containing the items array and transaction data.
