Monitoring Scroll Depth, Video Engagement, and Form Submissions in GA4

Monitoring scroll depth, video engagement, and form submissions in Google Analytics 4 (GA4) provides essential insights into how users interact with content, engage with media, and complete important actions on your site. These engagement metrics reveal how well your site’s content captures attention and where users might drop off, enabling you to optimize accordingly. In my experience, tracking these specific events often highlights areas of improvement that may otherwise go unnoticed.

Tracking Scroll Depth in GA4

Scroll depth tracking measures how far users scroll on a page. This metric is valuable for content-heavy websites where understanding user engagement with the content layout can inform design improvements.

  1. Setting Up Scroll Depth Tracking:

    • Go to Google Tag Manager (GTM) and create a new Tag for scroll tracking.
    • Set the Trigger to measure scroll depth at key intervals (e.g., 25%, 50%, 75%, and 100%).
    • Assign an Event Name like scroll_depth, and include parameters such as percentage and page_path to indicate the scroll depth and the page’s URL.

  2. Analyzing Scroll Depth Data:

    • Review scroll depth data in GA4 to see which pages keep users engaged and where they might lose interest. If users often stop scrolling before reaching the content’s end, consider revising the content layout or moving crucial information higher up on the page.

  3. Practical Use Cases for Scroll Depth:

    • Optimize Content Layout: Identify pages where users frequently drop off, indicating they may not find the content engaging or that it’s too lengthy.
    • A/B Test Content: Test different content structures, such as breaking down long-form articles into shorter sections or adding more visual elements, to see if users scroll further on optimized versions.

Monitoring Video Engagement in GA4

Video engagement tracking provides insights into user interactions with embedded videos, such as play, pause, and completion. Tracking these interactions helps you understand if video content resonates with your audience.

  1. Setting Up Video Engagement Tracking:

    • In GTM, create Tags for video actions (e.g., play, pause, and complete).
    • Use Triggers based on the specific video actions you want to track, and label each event with names like video_play, video_pause, and video_complete.
    • Include parameters like video_title and video_duration to capture the title and length of each video.

  2. Analyzing Video Engagement Data:

    • Access the Events report in GA4 to see which videos receive the most engagement. Look for patterns in where users pause or stop videos, as these may indicate points where content could be more engaging or informative.

  3. Practical Use Cases for Video Engagement:

    • Optimize Video Content: If viewers frequently stop watching at a certain point, consider editing that segment or adding more engaging content to retain interest.
    • Test Video Lengths: Experiment with different video lengths to see which ones hold user attention longer. If shorter videos have higher completion rates, consider breaking longer videos into shorter segments.

Tracking Form Submissions in GA4

Form submissions are vital interactions, especially for lead generation and e-commerce sites. Tracking form completion rates can help identify bottlenecks in the conversion process and inform improvements to increase form completion rates.

  1. Setting Up Form Submission Tracking:

    • In GTM, create a Tag for form submission events.
    • Use a Trigger that activates when users submit a form (often set to detect a form’s “submit” action).
    • Assign an Event Name like form_submit, and add parameters such as form_id or form_type to identify the specific form.

  2. Analyzing Form Submission Data:

    • Access the Events report in GA4 to examine which forms have the highest or lowest submission rates. Forms with lower completion rates may need optimization, such as reducing the number of required fields or improving the form layout.

  3. Practical Use Cases for Form Submission Tracking:

    • Reduce Form Friction: Identify forms with high abandonment rates and simplify them by removing unnecessary fields, making the form user-friendly.
    • Track Multi-Step Forms: For multi-step forms, set up events to track each stage. This allows you to see where users drop off and adjust the flow to encourage completion.

Using GA4’s Funnel Analysis for Scroll Depth, Video Engagement, and Form Submissions

GA4’s Funnel Exploration feature is ideal for visualizing user journeys through these tracked events. For instance, you could create a funnel to see how users progress from scrolling through a landing page, engaging with a video, and ultimately completing a form.

  1. Set Up a Custom Funnel:

    • Go to GA4’s Funnel Exploration and define each step based on your tracked events (e.g., scroll depth, video engagement, and form submission).
    • Analyze how many users complete each step to understand where users are most engaged or where they drop off.

  2. Practical Insights from Funnel Analysis:

    • Optimize the Conversion Path: If you notice a high drop-off after a specific step, such as video engagement, consider adjusting the content or adding a CTA to guide users to the next step.
    • Identify Content Gaps: By tracking which content elements users engage with most, you can align future content with these preferences, enhancing the user journey and increasing the likelihood of conversions.

Conclusion

Monitoring scroll depth, video engagement, and form submissions in GA4 provides actionable insights into user behavior. By understanding how users interact with content, videos, and forms, you can make data-driven adjustments to improve engagement and conversions. These tracking techniques, combined with GA4’s funnel analysis, empower you to optimize content, test new strategies, and ultimately enhance the user experience on your site.
