How to use Google Tag Manager to track microsite analytics

Author:

Google Tag Manager (GTM) simplifies tracking analytics for a microsite, allowing you to manage tags and scripts in a centralized platform without manual code editing. Whether your microsite is part of a larger domain (e.g., example.com/microsite) or on a subdomain (e.g., microsite.example.com), GTM can effectively monitor user behavior, conversions, and other metrics.

1. Understand the Requirements

Before implementing GTM, ensure the following prerequisites are met:

  1. Google Tag Manager Account: Set up a GTM container for your microsite.
  2. Google Analytics Account: Create a property for your microsite in Google Analytics 4 (GA4) or Universal Analytics (UA).
  3. Access to Your Microsite: Ensure you have the ability to add GTM container code to your microsite.
  4. Defined Goals: Identify the key metrics to track (e.g., page views, button clicks, form submissions).

2. Add Google Tag Manager to Your Microsite

To start tracking, you need to add the GTM container snippet to your microsite’s HTML.

Step 1: Get the GTM Snippet

  1. Log in to your GTM account and select the container for your microsite.
  2. Copy the GTM container code snippet.

Step 2: Install the Snippet

  1. Paste the container code in the <head> and <body> sections of your microsite’s HTML files.
  2. Save and upload the updated HTML files to your server.

3. Create a Google Analytics Tag

Google Analytics is the core tool for tracking microsite analytics. You’ll use GTM to deploy the GA tag.

Step 1: Create a GA4 Property

  1. In your Google Analytics account, create a property for your microsite.
  2. Set up Data Streams for your microsite URL.

Step 2: Set Up the GA4 Tag in GTM

  1. Log in to your GTM account and select your container.
  2. Navigate to the Tags section and click New.
  3. Name your tag (e.g., “GA4 Configuration – Microsite”).
  4. In the Tag Configuration panel:
    • Select Google Analytics: GA4 Configuration.
    • Enter your Measurement ID from your GA4 data stream.
  5. Under Triggering, add the All Pages trigger to track all page views on your microsite.

Step 3: Save and Publish

  1. Save the tag.
  2. Publish the container to push changes live.

4. Track Key Interactions

To gain deeper insights, set up tags to track specific user interactions, such as button clicks, form submissions, or downloads.

Example: Button Click Tracking

  1. Create a Trigger:
    • Go to Triggers in GTM and click New.
    • Name the trigger (e.g., “Button Click”).
    • Select Click – All Elements as the trigger type.
    • Set the trigger to fire only on clicks that match your criteria (e.g., click text, CSS selectors, or element ID).
  2. Create a Tag:
    • Go to Tags and click New.
    • Name the tag (e.g., “Track Button Clicks”).
    • Select Google Analytics: GA4 Event as the tag type.
    • Configure the event name (e.g., “button_click”) and parameters (e.g., “button_text”).
    • Link the trigger created earlier to this tag.
  3. Save and Publish.

Example: Form Submission Tracking

  1. Create a Trigger:
    • Go to Triggers in GTM and click New.
    • Select Form Submission as the trigger type.
    • Configure the trigger to fire on specific forms (e.g., by form ID or URL).
  2. Create a Tag:
    • Go to Tags and click New.
    • Select Google Analytics: GA4 Event and configure the event details (e.g., “form_submission”).
    • Add the form submission trigger to the tag.

5. Use Custom Dimensions for Microsite Insights

If your microsite shares the same GA property as your main site, use custom dimensions to differentiate microsite data.

Step 1: Configure a Custom Dimension

  1. In GA4, go to Admin > Custom Definitions > Create Custom Dimension.
  2. Set a dimension name (e.g., “Microsite Page”).
  3. Use a page-specific parameter to capture data (e.g., “page_location”).

Step 2: Pass Data via GTM

  1. In GTM, add a Variable (e.g., Page Path).
  2. Configure your GA4 tag to pass the variable as a parameter.

6. Monitor Cross-Domain Tracking

If your microsite exists on a subdomain or shares tracking with a parent site, enable cross-domain tracking to avoid data fragmentation.

Step 1: Update GA4 Settings

  1. In your GA4 property, go to Admin > Data Streams.
  2. Under Additional Settings, add your primary domain and subdomain to the List of Domains.

Step 2: Update GTM GA4 Tag

  1. Open your GA4 configuration tag in GTM.
  2. In the Fields to Set section, add a field named allowLinker and set its value to true.

7. Test and Debug

Testing ensures your tracking setup is working correctly.

Step 1: Enable GTM Preview Mode

  1. In GTM, click Preview to enter Debug mode.
  2. Open your microsite in a new tab to test the implementation.

Step 2: Validate with GA DebugView

  1. In GA4, go to Realtime > DebugView.
  2. Interact with your microsite and ensure data appears as expected.

Step 3: Use GTM Debug Console

  1. Verify that the correct tags fire for events like page views, button clicks, and form submissions.
  2. Debug and fix any issues before publishing live.

8. Analyze Microsite Performance

Once tracking is live, use Google Analytics to monitor microsite performance:

  1. Audience Overview: Understand visitor demographics and sources.
  2. Behavior Flow: Analyze how users navigate through the microsite.
  3. Event Reports: View interactions like button clicks or form submissions.
  4. Conversions: Track key actions tied to your business goals.

Conclusion

Using Google Tag Manager to track microsite analytics streamlines the process of setting up and managing tags. By configuring GA4, tracking key interactions, and using advanced features like cross-domain tracking, you can gain actionable insights into your microsite’s performance. Regular testing and monitoring ensure accurate data collection, helping you optimize the microsite for your audience and business objectives.
