Shopify directly integrates with Google Analytics. The set up is pretty simple. But when it comes to Google Tag Manager, there is no direct integration.

Follow the steps below to set up Google Tag Manager Shopify tracking:

Step-1: Create a new Google Tag Manager accountIf you already have the GTM account then log in.

Step-2: Click on the ‘Admin’ link and then click on ‘Install Google Tag Manager’:

install gtm

Step-3: Copy the first part of the GTM installation code:

Step-5: Click on ‘Themes’ under the ‘Online Store’ drop-down menu:


Step-6: Click on the ‘Actions’ drop-down menu and then select ‘Edit HTML / CSS’:

Step-13: Navigate to the home page of your Shopify store and then click on the ‘Google Tag Assistant’ icon on the top right-hand side, next to the browser address bar:

You should be able to see the ‘Google Tag Manager’ tag under the ‘Result of Tag Analysis’ column (with blue/green icon next to the identified tags). This shows that Google tag manager is now installed on your Shopify store.

Note: The red, yellow, blue and green icons next to identified tags, have all got special meaning:

So if you see a yellow or red icon next to identified tags then something is wrong with your GTM installation.

Caveats about using Google Tag Manager on a Shopify Store

#1 Do not use GTM to deploy the Google Analytics tag on your Shopify store. If you do that then the cross-domain tracking between your website and Shopify won’t work.

#2 Do not use GTM to install enhanced ecommerce tracking on your Shopify store. Enhanced ecommerce tracking is already built-in Shopify. Even if you install enhanced ecommerce via GTM, it won’t work. Shopify won’t read your data layers. So don’t do that.

#3 Use GTM to deploy tags other than Google Analytics and Enhanced Ecommerce like ‘Hotjar’, ‘Google Adwords conversion tracking’ etc.
