What is Google Tag Manager?

Google Tag Manager simplifies the management of marketing tags on your website.

The tool enables admins to add and update tags, such as Google Analytics or Facebook Pixel. It doesn’t need direct modification of the website's code.

GTM enables the efficient deployment of tags. It helps save time and reduces dependency on developers. It also provides event tracking and debugging tools to ensure smooth implementation.

GTM makes it easier to track user interactions and run marketing campaigns. Integrating GTM enables the management of various third-party tags through a single interface.

How Google Tag Manager Works?

1. Creating a GTM Account and Container

Creating a GTM Account and Container

  • You start by creating a Google Tag Manager account. Once you create the account, create a "container" for your website or app.

  • GTM provides a container snippet of code, which you add to every website page.

  • The snippet acts as the gatekeeper. It loads and manages all tags you configure in the GTM interface.

  • Insert the container script into the <head> and <body> sections of your site’s HTML.

2. Adding Tags

Adding Tags

  • Tags are small pieces of code used to collect and send data to third-party services. These include Google Analytics and Facebook Pixel.

  • Each tag serves a specific purpose. These include tracking page views or user interactions on the website.

  • GTM offers several pre-built tag templates for popular services, like Google Ads. It helps them integrate them into your website.

  • You can create custom HTML tags if the service you are using is not supported.

  • Once you create a tag, you define its parameters and customize its behavior on the website.

3. Setting Triggers

Setting Triggers

  • Triggers determine when and where you fire a tag. A tag should fire when a user visits a particular page or submits a form. The common trigger types include:

    1. Page views fire when you load a page or visit a URL.

    2. Click events fire when a user clicks a specific element on a page, like a button or a link.

    3. Form submission fires when a user submits a form.

    4. Custom triggers depend on more complex user actions. These include interacting with specific dynamic content on the site.

4. Preview and Debug

Preview and Debug

  • Before publishing your tags, Google Tag Manager for Magento 2 provides a preview mode. It allows you to test how the tags and triggers behave on your site in real-time.

  • You can see which tags are firing and check for any potential issues.

  • GTM also provides a debugging console. It allows you to view information about tag activity.

  • It helps you troubleshoot any problems with tags that are not firing as expected.

5. Tracking and Analytics

  • Once live, the container script on your website loads the tags based on the triggers you have set up.

  • If you configured a page view trigger for Google Analytics. GTM will fire the Google Analytics tag whenever the user visits a page.

  • Tags can track a wide range of user behaviors. These include page views and e-commerce transactions. Send the data to the respective services, such as Google Analytics or Google Ads.

  • Use the collected data to refine marketing campaigns and assess website performance.

5 Advanced GTM Configurations for Magento
