   • Log in to your Google Analytics account and select the property and view where you set up the scroll tracking.
2. Navigate to Events:
   • Go to “Behavior” > “Events” > “Top Events” to see an overview of the scroll depth events tracked.
3. Analyze Scroll Depth Data:
   • Drill down into specific event categories, actions, and labels to analyze scroll depth data.
   • Use secondary dimensions to gain additional insights (e.g., source/medium, landing page).

Additional Tips

• Adjust Thresholds: Experiment with different scroll depth thresholds to understand how users engage with different sections of your pages.
• Segmentation: Use segments in Google Analytics to compare scroll behavior across different user groups or traffic sources.
• Data Layer: For more advanced implementations or dynamic content, consider using a data layer in GTM to capture scroll depth data based on specific elements or interactions on your page.

By following these steps, you can effectively set up scroll tracking in Google Tag Manager to monitor user engagement and optimize your website’s content based on how users interact with your pages.
