How to Add Google Tag Manager to Shopify

What is Google Tag Manager?

Google Tag Manager (GTM) is a free tag management system that allows you to add and manage multiple tracking scripts on your Shopify store without editing your theme code every time. Using GTM, you can manage:

• Google Analytics 4 tracking
• Facebook Pixel
• Conversion events (purchase, form submission, add-to-cart)
• Custom tags for marketing and analytics tools

This guide covers two methods for installation: via Shopify’s Google & YouTube app (easier) or manual code injection (more control), plus how to test GTM with GemPages-built pages.

Before starting, ensure you have:

1. GTM Account & Container ID

Sign up at Google Tag Manager.

Create a container for your Shopify store and copy the Container ID (GTM-XXXXXXX).

2. Shopify Admin Access

Must have permission to edit themes or insert scripts.

3. Tracking Plan

Identify the events you want to track: page views, add-to-cart, checkout, purchases, form submissions.
