Conversion Tracking not tracking

Topic summary

A Shopify store owner reports that Google Ads conversion tracking works on all pages except checkout, as verified through Google Tag Assistant screenshots.

Root Cause Identified:

  • Shopify’s Checkout 2.0 uses iFrames that prevent standard GTM implementation from working on checkout pages
  • Traditional GTM code placement in theme.liquid files doesn’t reach the checkout environment
  • Proper tracking requires Shopify’s Customer Events with custom pixel implementation

Recommended Solutions:

Two experts suggest similar approaches:

  1. Remove existing Google tag connections from Shopify Settings
  2. Create a Custom Pixel in Shopify Admin → Settings → Customer Events
  3. Implement dataLayer code that subscribes to checkout events (checkout_completed, checkout_started)
  4. Configure GTM variables for transaction data (value, currency, transaction ID)
  5. Set up conversion tags with proper triggers in GTM

Additional Complications:

  • One user reports Simprosys app automation isn’t working despite claims it handles conversion tracking automatically
  • GDPR compliance with Cookie Consent Banner (Consent Mode v2) is required for European stores to record conversions
  • Multiple users confirm GTM preview mode shows the container missing on checkout pages

Status: Discussion remains open with users seeking working implementations for their specific setups.
