4 Website Actions You Can Track With Google Tag Manager

Why Track Website Actions?

Understanding how users interact with your website is fundamental to digital marketing success. Google Tag Manager (GTM) empowers marketers and developers to track critical user actions without constant code deployments. This guide explores four essential website actions you can track with GTM, providing implementation details and best practices for accurate data collection.

The data collected from these tracked actions feeds directly into Google Analytics 4, informing conversion optimization strategies, content performance analysis, and user experience improvements. Whether you're tracking button clicks, form submissions, or content engagement, GTM provides the flexibility to capture nuanced user behavior patterns.

What Makes GTM Powerful for Tracking

Google Tag Manager serves as a centralized platform for managing all tracking tags, eliminating the need for manual code edits for each new tracking implementation. This approach offers several advantages:

• Efficiency: Deploy new tracking without developer intervention
• Accuracy: Built-in debugging and preview tools verify tag firing
• Flexibility: Support for custom events and complex trigger conditions
• Version Control: Track changes and revert when needed

Our web development services include comprehensive analytics setup to ensure you capture the data that matters most to your business objectives.

Action 1: Button and Link Click Tracking

Click tracking forms the foundation of understanding user engagement with interactive elements on your website. Whether it's a call-to-action button, navigation link, or outbound link, tracking these interactions reveals which elements drive user behavior.

GTM provides built-in trigger types for capturing clicks on various elements. The platform automatically captures click-related variables like Click Element, Click ID, Click Classes, and Click Text, which can be used to create precise triggers.

Setting Up Click Tracking

To track button clicks effectively, you'll need to create a trigger that identifies the specific click event, then configure a tag that sends this data to your analytics platform.

Trigger Configuration Options:

When implementing click tracking, focus on your most important conversion actions first. Our digital marketing services can help you prioritize which interactions to track based on your business objectives.

Action 2: Form Submission Tracking

Form submissions represent critical conversion points on most websites, yet tracking them accurately can be challenging due to various form submission methods and page behaviors. GTM offers multiple approaches to capture these important interactions.

Methods for Form Tracking

Method 1: Built-in Form Trigger

GTM's built-in form trigger captures form submissions automatically:

Trigger Type: Form Submission
Trigger Fires On: All Forms

Method 2: Data Layer Push on Success

For single-page applications or AJAX forms, work with developers to implement data layer events:

window.dataLayer.push({
 'event': 'form_submission_success',
 'form_id': 'contact-form',
 'form_name': 'Contact Form',
 'form_location': 'footer'
});

Method 3: Click-Based Tracking for Multi-Step Forms

For complex forms where submission happens on a final button click:

Trigger Type: Click - All Elements
Trigger Fires On: Some Clicks
Condition: Click Text equals "Submit Application"

Best Practices for Form Tracking

• Track form errors for optimization insights
• Capture form field values for segmentation (ensure privacy compliance)
• Use form ID attributes for precise targeting
• Consider tracking time-to-submit as a proxy for form usability

Implementing proper form tracking helps identify friction points in your conversion funnel and reveals opportunities for improvement.

Action 3: Scroll Depth Tracking

Understanding how far users scroll through your content reveals engagement patterns that page view data alone cannot capture. Scroll depth tracking helps identify whether users are consuming your content or bouncing immediately.

Implementing Scroll Tracking

GTM offers built-in scroll depth triggers that fire based on percentage thresholds:

Trigger Type: Scroll Depth
Vertical Scroll Depths: 25%, 50%, 75%, 100%
Trigger Fires On: Each Page

Enhanced Scroll Tracking with Data Layer

For more granular control, implement custom scroll tracking:

let milestones = [25, 50, 75, 100];
let tracked = {};

window.addEventListener('scroll', function() {
 let scrollPercent = Math.round(
 (window.scrollY / (document.body.scrollHeight - window.innerHeight)) * 100
 );
 
 milestones.forEach(milestone => {
 if (scrollPercent >= milestone && !tracked[milestone]) {
 tracked[milestone] = true;
 window.dataLayer.push({
 'event': 'scroll_depth',
 'depth_percent': milestone,
 'page_path': window.location.pathname
 });
 }
 });
});

Using Scroll Data Effectively

Scroll depth data should inform content strategy decisions. Pages where users consistently scroll to 100% indicate strong content engagement, while high bounce rates at shallow depths signal potential content or UX issues. This insight is valuable for optimizing your content marketing strategy.

Action 4: Video Engagement Tracking

Video content represents a significant engagement opportunity, but standard page analytics don't capture how users interact with embedded videos. GTM enables comprehensive video tracking for platforms like YouTube and Vimeo.

YouTube Video Tracking Setup

GTM provides built-in support for YouTube video tracking through the YouTube Video trigger:

Trigger Type: YouTube Video
Trigger Fires On: Completion, Pause, Progress
Progress Thresholds: 10%, 25%, 50%, 75%

Custom Video Tracking for Non-YouTube Videos

document.querySelectorAll('video').forEach(video => {
 video.addEventListener('ended', function() {
 window.dataLayer.push({
 'event': 'video_completed',
 'video_title': this.dataset.videoTitle,
 'video_duration': this.duration
 });
 });
 
 video.addEventListener('timeupdate', function() {
 if (this.currentTime / this.duration >= 0.75 && !this.dataset.seventyFiveTracked) {
 this.dataset.seventyFiveTracked = 'true';
 window.dataLayer.push({
 'event': 'video_progress',
 'video_title': this.dataset.videoTitle,
 'progress_percent': 75
 });
 }
 });
});

Video Metrics That Matter

Video engagement metrics help you understand which content resonates with your audience, informing both your content marketing and overall marketing strategy.

Performance Considerations

Impact on Page Load

Every tag added to GTM has the potential to impact page performance. While GTM optimizes tag loading, excessive or poorly configured tags can slow page load times.

Optimization Strategies

1. Limit Tag Firing: Configure tags to fire only on relevant pages
2. Use Partytown: Offload third-party scripts to web workers
3. Regular Audits: Review and remove unused tags quarterly
4. Prioritize Critical Tags: Ensure essential tracking isn't delayed

Efficient Trigger Configuration

Poorly designed triggers can cause tags to fire unnecessarily, consuming resources and potentially inflating data. Use precise trigger conditions:

Instead of: All Clicks
Use: Some Clicks where Click Classes contains "track-me"

This specificity ensures tags fire only when intended, reducing performance impact and improving data accuracy. Proper tracking implementation is essential for maintaining both site performance and data quality.

Testing Before Deployment

Always test tracking implementations in GTM's Preview mode before publishing. This prevents data quality issues and ensures accurate analytics from day one.

Testing and Debugging

Preview Mode Essentials

Before deploying any tracking implementation, use GTM's Preview mode to verify tag firing. This built-in debugging tool allows you to navigate your site while monitoring which tags fire and which don't.

Debugging Workflow:

1. Enter Preview mode
2. Navigate through tracked interactions
3. Verify tags fire correctly
4. Check data layer values
5. Confirm data appears in GA4 Real-Time reports

Common Debugging Tools

Implementation Checklist

Before launching your tracking implementation:

• Test all triggers in Preview mode
• Verify data appears in GA4 Real-Time view
• Document tracking configuration for future reference
• Set up custom dimensions for enhanced segmentation
• Establish regular audit schedule
• Train team members on data interpretation

Proper testing and documentation ensures your tracking infrastructure supports long-term marketing optimization and helps inform strategic decisions across your digital marketing initiatives.

Conclusion

Mastering these four website action tracking capabilities transforms raw user interaction data into actionable marketing intelligence. Google Tag Manager's flexibility enables precise tracking configurations while maintaining site performance. Start with click tracking for your primary CTAs, expand to form and scroll tracking for engagement insights, and leverage video tracking for content performance analysis.
