Google Ads Remarketing Pixel For Shopify (Native) V1.05

Tutorial is available at: https://feedarmy.com/kb/adding-google-adwords-remarketing-tag-to-shopify/

Includes lifetime updates for Version 1 — no subscriptions, no surprises. You’ll get every future fix or improvement as long as Shopify and Google keep the same tracking structure.

Changelog

Version 1.05 – 7 th April 2025

 New Features:

• Automatic Cookie Consent Handling (with Fallback) The script now respects Shopify’s customer privacy API. If a consent app is installed, it will only run tracking after marketing consent is given If no cookie banner or consent app is present, the script automatically runs, ensuring tracking still works out of the box.
• If no cookie banner or consent app is present, the script automatically runs, ensuring tracking still works out of the box.

 Improvements:

• Universal Compatibility Works seamlessly with or without cookie consent apps — no extra setup needed.
• Console Warnings Helpful messages added to the browser console when the privacy API is not detected or consent is denied — makes troubleshooting easier for store owners.

 Compliance Ready (but Flexible) For stores in regions like the EU/UK/CA, tracking respects privacy laws by default. For others, no setup changes are needed — just paste and go.

Version 1.04 – 6th April 2025

 New Features:

• begin_checkout event added
  Tracks when a user starts the checkout process, improving funnel visibility and audience targeting.
• remove_from_cart event added
  Helps build audiences based on cart abandonment behavior.
• customer_login and customer_account_created events added
  Enables retargeting or exclusion of logged-in users and new customer sign-ups for more refined remarketing lists.

 Improvements:

• Deduplication logic for purchase events
  Prevents duplicate conversions being sent to Google Ads during multi-trigger scenarios.
• Null/undefined safety added to all event handlers
  Prevents errors when product or variant data is missing—ensures reliable performance even with unusual product setups (e.g. bundles, custom apps).
• Standardized product ID generation
  All event handlers now use a centralized getItemId() function for consistent and clean tracking across all product ID formats (shopify, sku, variant_id, parent_id).
• Inline logic for begin_checkout event
  No longer depends on shared utility functions, keeping things fast and lightweight.
• Conversion callback (event_callback) added to purchase
  Ensures Google Ads recognizes the conversion even during quick page transitions or redirects.

 Refactoring:

• Cleaner code structure and reduced duplication.
• All item processing logic now uses Array.map().filter() for safe and accurate payload creation.
