How to Trigger Custom Events in Google Tag Manager: A Step-by-Step Guide
Triggering events from Google Tag Manager (GTM) is a powerful way to track interactions on your website, such as clicks, form submissions, pageviews, video plays, or any custom event that you want to track in Google Analytics or other platforms. Here’s a step-by-step guide to trigger events from GTM:
Step-by-Step Guide to Triggering Events from Google Tag Manager (GTM)
1. Set Up Google Tag Manager on Your Website
Before you can trigger events, you need to ensure that GTM is properly installed on your website. If you’ve already done this, skip to the next step.
Install the GTM Code: Get your GTM container code from the Google Tag Manager dashboard and paste it just below the <head> tag of your website. Make sure it’s on all pages.
2. Define the Event You Want to Track
Decide what action you want to track. GTM triggers can be set for a variety of user actions like:
- Button clicks
- Form submissions
- Video plays
- Scroll depth
- Pageviews
- Custom events
Let’s take the example of tracking a button click event.
3. Create a New Tag in Google Tag Manager
Tags in GTM are snippets of code that execute (or "fire") when specific conditions (triggers) are met. To create a new tag for your event:
Steps:
- Log into GTM and navigate to your container.
- On the left menu, click “Tagsâ€.
- Click the “New†button to create a new tag.
Name your tag something descriptive like “Button Click Event - Purchase Buttonâ€.
4. Configure Your Tag
The tag type depends on which platform you’re sending the event data to. Let’s say you’re sending this event to Google Analytics 4 (GA4).
For GA4 Event:
- In the Tag Configuration section, click on Tag Type.
- Select Google Analytics: GA4 Event.
In the Measurement ID, input your GA4 Measurement ID (from your GA4 account).
Under Event Name, give your event a name. For example:
Event Name: button_click or purchase_click (or any custom name).
In Event Parameters, you can define extra details about the event:
- Parameter Name: button_text
- Value: Select Click Text from the GTM variable list to capture the text of the clicked button.
5. Set Up the Trigger for the Event
Triggers tell GTM when to fire your tag. In this case, you want the tag to fire when a specific button is clicked.

Steps:
- In your tag creation screen, scroll down to Triggering.
- Click on “+†to add a new trigger.
- Name the trigger something descriptive, like “Button Click Trigger - Purchase Buttonâ€.
- In Trigger Configuration, select Click – All Elements (if you're tracking any clickable element) or Click – Just Links (if you’re only tracking link clicks).
- Choose Some Clicks to narrow down the trigger.
- Set the condition based on the button you want to track:
- For example, you can trigger the event when Click ID or Click Text contains the specific button identifier.
- Example Condition: Click Text contains "Buy Now" or Click ID equals "purchase-btn".
- Save your trigger.
6. Test Your Setup Using GTM Preview Mode
Before you publish your tag, it’s crucial to test it in Preview Mode to ensure everything works as expected.
Steps:
- In the GTM dashboard, click the “Preview†button at the top right.
- Enter the URL of your website where the button or event exists.
- You’ll now be in Debug Mode. Interact with your website (click the button you’re tracking), and in the GTM Debugger, see if the event is being triggered.
If it works, you should see the tag fire under Tags Fired on This Page.
7. Publish Your Tag
Once you’ve tested the setup and confirmed that the tag fires correctly:
Go back to your GTM workspace.
Click “Submit†in the top right corner.
Add a version name and description (optional but helpful for tracking changes).
Click “Publishâ€.
8. Verify Event in Google Analytics (or other platforms)
After publishing the tag, you’ll want to verify that the event is being properly recorded in your tracking platform.
For Google Analytics 4:
Go to Google Analytics 4 → Realtime: Check the real-time reports to see if your custom event (button_click, or whatever you named it) appears after performing the action on your website.
You can also check the Events tab in the Reports section of GA4 to see the event you created.
Common Event Triggers You Can Set in GTM
- Form Submission Tracking: Track form submissions to see when users successfully submit contact forms or sign up forms.
- Scroll Depth Tracking: Measure user engagement by tracking how far down they scroll on your page (e.g., 25%, 50%, 75%, 100%).
- Video Engagement: Track video interactions, such as play, pause, or percentage viewed (if using platforms like YouTube).
- Custom JavaScript Event: Trigger custom events based on JavaScript or when specific conditions on your site are met.
Important Variables for Triggers:
- Click Text: Captures the text within the clicked element (useful for buttons with text like "Buy Now").
- Click ID: Captures the ID of the clicked element.
- Click URL: Captures the URL of the clicked element if it’s a link.
- Form ID: Useful for tracking form submissions.
- Page Path: Tracks specific page views (useful for page-based triggers).
Conclusion
Google Tag Manager offers a flexible and powerful way to trigger custom events and track specific actions on your website without having to modify your site’s code. The combination of well-configured tags, triggers, and variables will allow you to track important events that help you understand user behavior, optimize campaigns, and improve website performance.
By following the steps outlined above, you’ll be able to trigger custom events with GTM and ensure those events are captured in Google Analytics or any other tool you’re integrating with.
