Why Do We Need GA4 (Google Analytics 4) in Magento 2?

Google Analytics 4 (GA4) is the next generation of Google’s analytics platform, that provides deeper insights into customer behavior and eCommerce performance. For Magento 2 store owners, GA4 is more important than ever — here’s why:

Future-Proof Analytics

Universal Analytics (UA) was sunset in 2023, and GA4 is now the default and only supported platform. To continue tracking and analyzing your store’s data, GA4 integration is a must.

Understand Customer Journeys Better

GA4 allows you to track users across devices and sessions, so you can see how customers interact with your store — from browsing to checkout.

Enhanced eCommerce Insights

With GA4 you can track:

  • Which products are viewed the most
  • Add-to-cart and checkout behavior
  • Which products drive the most revenue
  • Conversion rates for different traffic sources

Event-Driven Data Collection

Unlike UA’s session-based model, GA4 is event-driven, so you can track detailed actions like clicks, scrolls, video plays, and more — giving you granular insight into user behavior.

Data-Driven Decision Making

With GA4 data, Magento 2 merchants can:

  • Optimize product placement and promotions
  • Improve user experience
  • Identify and fix drop-off points in the purchase funnel
  • Increase ROI through better targeting and personalization

In short, GA4 gives your Magento 2 store advanced analytics to make smarter, data-backed decisions and stay ahead in the game.

Benefits of Using GA4 + GTM in Magento 2

Integrating GA4 with GTM makes tracking smarter and simpler. GTM lets you manage all tags without touching Magento’s code, saving time and effort.

  • Manage all tracking tags without editing Magento code
  • Easily add, update, or remove tags anytime
  • Track detailed events like clicks and conversions
  • Improve data accuracy and reporting
  • Test and debug tags before going live
  • Save time and reduce development costs

Two Options: Manual vs. Extension

When it comes to integrating Google Analytics 4 (GA4) with Google Tag Manager (GTM) in your Magento 2 store, you have two choices:

  • Manual: Create your GTM and GA4 accounts, add GTM code snippets to your Magento theme, and configure all tags, triggers and variables manually. You have full control but more technical knowledge and effort required.
  • Extension-Based (Recommended): Use the MageDelight GA4 with GTM extension and the entire process is automated. The extension will install, configure and track events for you, saving time and reducing errors.

For most store owners we recommend the extension for a faster, easier and more reliable setup. If you prefer the manual way, read on.

1. Setting Up GA4 + GTM in Magento 2 (Manually)

Want to connect Google Analytics 4 (GA4) and Google Tag Manager (GTM) to your Magento 2 store without using an extension?

You can absolutely do it yourself — it just takes a little more technical know-how. Don’t worry though, this step-by-step guide will walk you through everything you need.

Heads up: This method involves working in your Magento backend and configuring GTM manually. If you’d prefer a faster, easier option, check out our one-click extension instead!

Step 1. Create Your GTM Account & Container

Head over to Google Tag Manager and log in.

Click Create Account, then:

  • Enter an account name (e.g., Magento Store - GTM)
  • Choose your country
  • Select Web as the target platform
  • Click Create, agree to the terms — and you’re all set! Your GTM container is now ready.

Create GTM Account and Container

Ignore this step if you already have an account in GTM.

Step 2. Grab Your GTM Code Snippets

Once your container is created, GTM will display two code snippets:

  • The <head> snippet (for JavaScript tracking)
  • The <noscript> snippet (for users with JavaScript disabled)

GTM Codes

Pro tip: Keep this page open — you’ll need these snippets in the next step.

Step 3. Add GTM Code to Magento 2

Log in to your Magento Admin Panel.

Go to:

Content > Design > Configuration, then edit your active theme.

Paste the snippets as follows:

  • Place the <head> snippet under HTML Head > Scripts and Style Sheets

Add Head Tag in HTML Head

  • Place the <noscript> snippet under Footer > Miscellaneous HTML

Add Noscript Tag in Footer

Save your changes, then clear the Magento cache at System > Cache Management.

Step 4. Set Up GA4 in Google Analytics

Next, head to Google Analytics and log in.

Click the ⚙️ Admin button, then:

  • Under Property, click Create Property and fill the details.

Create New Propery in Admin of GA

  • Create a Web Data Stream, then copy your Measurement ID (it starts with G-).

Step 5. Link GA4 to GTM

Now, go back to GTM and create your GA4 tag:

  • Click Tags > New
  • For tag type, select Google Analytics: GA4 Configuration
  • Paste your Measurement ID from GA4
  • Set the trigger to All Pages
  • Save your tag and hit Submit to publish the container.

Done — GA4 is now connected to your store through GTM!

Step 6. Make Sure It’s Working

Here’s how to double-check everything is set up correctly:

Quick Check:

  • Open your store in a browser and check the Realtime Report in GA4 — you should see active users.

Thorough Check:

  • Use GTM’s Preview Mode to ensure tags are firing properly.
  • Check GA4’s DebugView for detailed event data.

Troubleshooting Tips

  • Didn’t publish your GTM container? Go back and click Submit.
  • Not seeing data? Make sure ad blockers are turned off while testing.
