Google Tag Manager + Google Analytics 4 for Magento 1

What is Google Tag Manager and GA4 for Magento 1?

Google Tag Manager (GTM) enables Magento 1 merchants to deploy, manage, and maintain third-party marketing tags, conversion pixels, and analytics scripts without editing core template files.

Google Analytics 4 (GA4) provides event-driven measurement and cross-device reporting. With our Google Tag Manager + GA4 Extension for Magento 1, you can capture crucial ecommerce events (view item, add to cart, checkout steps, purchases) and import our ready-to-use GTM container JSON file for fast deployment.

Installation Guide

Step 1 - Manual Installation

• Download the extension package.
• Unzip the archive.
• Copy the contents into your Magento 1 root directory according to the file structure (app/, skin/, etc.).

Step 2 - Configure Extension in Magento Admin

1. Log into your Magento 1 Admin Panel.
2. Navigate to System > Configuration.
3. Under the MagePal tab, select Google Tag Manager.

Google Tag Manager Account Setting & Configuration

The quickest way to configure your Google Tag Manager Container is to use our auto-import JSON configuration file for Google Tag Manager. Our configuration (.json) file automatically generates tags, triggers, and variables in your GTM container.

For step-by-step instructions, see our Google Analytics 4 JSON Import Configuration Guide.

Custom Success Page Tracking

If your store uses a custom checkout module or one-page checkout extension, add the following reference block to your theme’s local.xml layout file:

app/design/frontend/<your_package>/<your_theme>/layout/local.xml

<checkout_onepage_success>
    <reference name="magepal_gtm_datalayer">
        <block type="googletagmanager/order" name="magepal_gtm_block_order" />
    </reference>
</checkout_onepage_success>

Replace checkout_onepage_success with your custom success page layout handle if different.
