How do I set up custom events in Google Tag Manager?

Asked on Nov 09, 2025

Answer

To set up custom events in Google Tag Manager (GTM), you need to create a new tag that sends event data to Google Analytics 4 (GA4) when a specific user interaction occurs on your website. This process involves configuring a tag and a trigger within GTM.

<!-- BEGIN COPY / PASTE -->
    1. Sign in to your Google Tag Manager account.
    2. Click on "Tags" in the left-hand navigation.
    3. Click "New" to create a new tag.
    4. Choose "Google Analytics: GA4 Event" as the tag type.
    5. Enter your GA4 Measurement ID.
    6. Define the event name and parameters (e.g., event_category, event_action).
    7. Click on "Triggering" and select or create a trigger that defines when the event should fire.
    8. Save the tag and publish your container.
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure that your GA4 property is properly linked to your GTM container.
Test your setup using GTM's Preview mode to verify that the event fires as expected.
Use descriptive event names and parameters to maintain clear and useful analytics data.
After publishing, check the Realtime report in GA4 to confirm event tracking.
