How to set up event tracking with Google Tag Manager

Author:

Setting up event tracking in Google Tag Manager (GTM) is essential for monitoring user interactions on your website. Event tracking allows you to capture specific actions, such as button clicks, form submissions, video plays, downloads, and more. This data can be sent to Google Analytics (GA) or other tools to help you understand how users engage with your content.

Here’s a comprehensive guide to setting up event tracking with GTM:

Step 1: Set Up Google Tag Manager on Your Website

Before tracking any events, ensure that GTM is properly installed on your website. If GTM is not yet installed:

  1. Create a GTM Account: Go to Google Tag Manager and create an account if you don’t already have one.
  2. Create a Container: Set up a container for your website and GTM will provide you with two pieces of code.
  3. Install GTM Code: Add the code snippets to the <head> and <body> sections of your website’s HTML.

Once GTM is set up, you can proceed with event tracking.

Step 2: Identify the Event You Want to Track

Decide what type of user interactions you want to track. Common events include:

  • Button clicks
  • Link clicks
  • File downloads
  • Video plays
  • Form submissions
  • Scroll depth
  • Social media shares

Each of these actions can be tracked using GTM’s built-in triggers and variables.

Step 3: Enable Built-in Variables

Before setting up event tracking, you need to enable GTM’s built-in variables to capture useful data about user interactions.

  1. Open GTM: Log in to your GTM account and open the container for your website.
  2. Go to Variables: On the left-side menu, click Variables.
  3. Configure Built-in Variables: Scroll down and click Configure under the Built-in Variables section.
  4. Enable Click Variables: Check the following variables related to clicks:
    • Click Element
    • Click Classes
    • Click ID
    • Click Target
    • Click Text
    • Click URL

These variables help you capture key details about the clicked element, such as its ID, class, text, or URL.

Step 4: Create a Trigger for the Event

A trigger in GTM is a condition that tells GTM when to fire a tag. To track an event, you need to define a trigger based on the action you want to track.

Example: Track Button Clicks

  1. Go to Triggers: In GTM, click on Triggers from the left menu.
  2. Create a New Trigger: Click New to create a trigger.
  3. Trigger Configuration:
    • Trigger Type: Select Click – All Elements (for tracking clicks on any element).
    • Trigger for Some Clicks: Choose Some Clicks if you want to track a specific button or element. This is where you’ll define the trigger conditions, such as:
      • Click Classes equals “cta-button” (to track a button with a specific class name).
      • Click ID equals “download-btn” (to track a button by its ID).
      • Click Text contains “Submit” (to track a button with a specific text label).
    • Trigger for All Clicks: Alternatively, select All Clicks if you want to track every click on your website.
  4. Save: Name the trigger (e.g., “Button Click Trigger”) and save it.

Step 5: Create a Tag to Send the Event Data

Once you have a trigger, you need to create a tag that sends the event data to Google Analytics or another analytics tool.

For Google Analytics 4 (GA4) Users:

  1. Go to Tags: Click on Tags from the left-side menu.
  2. Create a New Tag: Click New to create a new tag.
  3. Tag Configuration:
    • Tag Type: Select Google Analytics: GA4 Event.
    • Configuration Tag: Choose your GA4 configuration tag, or if you don’t have one set up yet, create it by entering your Measurement ID (found in GA under Admin > Data Streams).
    • Event Name: Name the event something descriptive, like “button_click” or “cta_click.”
  4. Add Event Parameters: You can add custom event parameters to provide more context about the interaction. Common parameters include:
    • Button Text: Set the value to {{Click Text}}.
    • Button URL: Set the value to {{Click URL}}.
  5. Assign the Trigger: Attach the trigger you created earlier (e.g., “Button Click Trigger”).
  6. Save the Tag.

For Universal Analytics (UA) Users:

  1. Go to Tags: Click on Tags from the left menu.
  2. Create a New Tag: Click New to create a new tag.
  3. Tag Configuration:
    • Tag Type: Select Google Analytics: Universal Analytics.
    • Track Type: Choose Event.
    • Event Tracking Parameters:
      • Category: Enter a descriptive category, such as “Button Click.”
      • Action: Enter “Click” or another action that describes the interaction.
      • Label: Use {{Click Text}} or {{Click URL}} to capture information about the clicked element.
    • Google Analytics Settings: Select your Google Analytics tracking ID.
  4. Assign the Trigger: Attach the trigger you created earlier (e.g., “Button Click Trigger”).
  5. Save the Tag.

Step 6: Test the Event Tracking in Preview Mode

Before you publish your changes, it’s important to test your event tracking setup to ensure everything works as expected.

  1. Enable Preview Mode: In GTM, click the Preview button at the top-right corner of the screen. This will open a new tab where you can enter your website URL.
  2. Test the Event: Interact with the elements on your website (e.g., click the button you want to track). In the GTM Debugger window, you should see the event trigger under the Tags Fired section.
  3. Verify Variables: Check that the appropriate variables (e.g., Click Text, Click URL) are being passed correctly in the debugger.

Step 7: Publish Your Changes

Once you’ve confirmed that event tracking is working correctly:

  1. Exit Preview Mode.
  2. Click Submit in GTM.
  3. Provide a name and description for the version (e.g., “Event Tracking for Button Clicks”).
  4. Click Publish to push the changes live.

Step 8: View Event Data in Google Analytics

Once the tag is live, the event data will be sent to Google Analytics.

For Google Analytics 4 (GA4) Users:

  1. Log in to your Google Analytics account.
  2. Navigate to Reports → Engagement → Events.
  3. Look for your custom event (e.g., “button_click”) to see how often the event was triggered.

For Universal Analytics (UA) Users:

  1. Log in to your Google Analytics account.
  2. Navigate to Behavior → Events → Overview.
  3. Look for your event category (e.g., “Button Click”) to view event data.

Step 9: Advanced Event Tracking Options

You can further customize event tracking in Google Tag Manager by:

  • Tracking Different Types of Events: Repeat the steps for different interactions like video plays, form submissions, or file downloads.
  • Customizing Event Parameters: Capture more specific details about the event by passing additional variables or static values.
  • Using Auto-Event Listeners: GTM has built-in event listeners for scroll tracking, form submissions, and more, which can make tracking these events easier.

Conclusion

Event tracking in Google Tag Manager allows you to monitor user interactions and gain valuable insights into how visitors engage with your website. By following these steps, you can easily set up event tracking for various user actions, send that data to Google Analytics, and use it to optimize your website’s performance and user experience. GTM’s flexibility and ease of use make it a powerful tool for event tracking and web analytics.
