Install on WooCommerce

WooCommerce runs on top of WordPress. The recommended install uses GTM4WP — the industry-standard plugin that handles GTM injection AND auto-pushes WooCommerce dataLayer events.

Step 1 — Install GTM4WP

In WordPress Admin → Plugins → Add New, search for GTM4WP (by Thomas Geiger, 200k+ active installs). Install + Activate.

Plugin URL: wordpress.org/plugins/duracelltomi-google-tag-manager

Step 2 — Paste your GTM container ID

1. WordPress Admin → Settings → Google Tag Manager → General
2. Paste your GTM-XXXXXXX container ID into Google Tag Manager ID
3. Set Container code on/off to Enabled
4. Save

Step 3 — Enable WooCommerce integration

This is the key step that makes WooCommerce events fire automatically.

1. Same settings page → Integration tab
2. Find the WooCommerce section and enable:
   • Track classic e-commerce
   • Track enhanced e-commerce
   • Track product impressions
   • Track product clicks
   • Add to cart through AJAX
   • Purchase confirmation page event
3. Save

GTM4WP now pushes GA4-compatible ecommerce events (view_item, add_to_cart, begin_checkout, purchase) to the dataLayer on every relevant page. TagEasy's WooCommerce event templates listen for these exact event names.

Step 4 — Verify in GTM Preview

1. In GTM, click Preview
2. Open your store, browse to a product page — GTM's debug panel should show a view_item dataLayer push
3. Add it to cart — add_to_cart
4. Proceed to checkout — begin_checkout
5. Complete a test purchase (use Stripe test mode if you've enabled it on WooCommerce) — purchase with the order's transaction_id + value

Pre-built event templates for WooCommerce

• woocommerce:ga4:view_item
• woocommerce:ga4:add_to_cart
• woocommerce:ga4:begin_checkout
• woocommerce:ga4:purchase

All flagged with installNote: gtm4wp_recommended — the TagEasy wizard surfaces a callout reminding you to install GTM4WP for these to fire.

Alternative — manual install without GTM4WP

If you can't install the plugin, follow the WordPress install for the base GTM snippet, then write your own dataLayer.push() calls in WooCommerce hooks (woocommerce_after_single_product, woocommerce_add_to_cart, etc.). This is much more work — most users go GTM4WP.

Common gotchas

• Other WooCommerce GA plugins — disable any other GA-for-WooCommerce plugin (Google for WooCommerce, MonsterInsights eCommerce, etc.). They'll double-fire events.
• Caching — clear WP cache after enabling GTM4WP's WooCommerce integration.
• High-Performance Order Storage (HPOS) — GTM4WP is HPOS-compatible. No special steps.
