Step-by-Step: Installing Google Tag Manager on Shopify

Setting up google tag manager for shopify is a powerful way to gain full visibility over your store’s data. Whether you’re a first-time user or leveling up your analytics, following the right steps ensures you capture every key event. Let’s break down each installation method, so you can choose the best fit for your business.

Preparation: Prerequisites and Planning

Before you install google tag manager for shopify, start by laying a strong foundation. First, create a GTM account and a dedicated container for your Shopify store. This container is where you’ll manage all your tags, triggers, and variables.

Next, gather all tracking IDs you plan to use. These might include Google Analytics, Google Ads, Meta Pixel, or others. Having these on hand streamlines your setup and helps avoid missing crucial steps.

Always back up your Shopify theme files before making any changes. This precaution saves you from headaches if you need to revert. Audit your current tags to make sure you don’t end up with duplicates, which can skew your analytics.

Finally, identify the key actions and events you want to track, such as purchases, sign-ups, or specific product interactions. This planning stage is vital for anyone installing google tag manager for shopify, ensuring your data is clean and actionable.

Method 1: Using Shopify’s Google & YouTube App

The easiest way to integrate google tag manager for shopify is through Shopify’s Google & YouTube App. Head to your Shopify Admin, select Apps, and install the Google & YouTube app. Connect your Google account, and the app will handle most of the heavy lifting for you.

With this method, Google Analytics and Google Ads tags are automatically managed. This means less manual work and fewer chances for errors. It’s perfect for beginners or anyone who prefers a streamlined process.

However, this approach mainly supports Google products. If you want to track other platforms like Meta or TikTok, you’ll need to supplement with other methods. For those migrating from older tag setups, this Shopify's Google & YouTube App Migration Guide provides detailed steps to ensure your tracking remains accurate.

Method 2: Via Shopify’s Google Analytics Settings

If you’re already using Google Analytics 4, Shopify’s built-in analytics settings offer a seamless way to connect google tag manager for shopify. Navigate to Shopify Admin, go to Online Store, then Preferences, and find the Google Analytics section.

Here, link your GA4 property. You can then integrate GTM using the Google tag option. This ensures that analytics data flows smoothly between Shopify and Google, giving you reliable insights.

This method is especially useful for stores that have already invested in GA4 and want to keep everything centralized. It also reduces the risk of duplicate code, since Shopify manages the connection natively.

Method 3: Manual Installation via Shopify Theme Files

For full control over google tag manager for shopify, manual installation is the way to go. Access your Shopify Admin, head to Online Store, then Themes, and choose Edit Code. Open your theme.liquid file.

Paste your GTM container code right after the <head> tag:

<!-- Google Tag Manager -->
<script>
(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXXXX');
</script>
<!-- End Google Tag Manager -->

Double-check for existing tag scripts to avoid duplication. Save and publish your changes. This method supports all tag types, including Meta Pixel and TikTok. Remember, theme updates may overwrite your code, so always document your setup for future reference.

Here’s a quick comparison of the three methods:

Verifying Your GTM Installation

After setting up google tag manager for shopify, always verify your installation. Start by enabling GTM’s Preview Mode to check if tags are firing as expected. The Google Tag Assistant Chrome extension is another handy tool for real-time verification.
