Scroll depth tracking allows you to measure how far down a page a visitor scrolls. This can be viewed per page or as an average, using the built-in scroll tracking feature.

​
Enabling Scroll Tracking

To enable scroll tracking, navigate to: Settings > Scroll Depth Tracking Here you can define up to four scroll breakpoints as a comma-separated list of percentages (e.g. 25,50,75,100). A scroll event will be fired when a user scrolls past each defined breakpoint on a page. These events can be used in two ways:
  • Metric: Avg Scroll Depth
  • Dimension: Scroll Depth

​
Example: Scroll Depth Dimension

The Scroll Depth dimension reflects the percentage of the page the visitor reached based on your defined thresholds.
Page PathScroll DepthPage Views
/about-us25%500
/about-us50%600
This means that 600 page views reached at least 50% scroll on the /about-us page.

​
Example: Average Scroll Depth Metric

The Avg Scroll Depth metric is a weighted average across all scroll events for a given page.
Page PathAvg Scroll DepthPage Views
/about-us38.6%1,100
This tells us that, on average, users scroll 38.6% down the /about-us page.

​
Important Notes

  • Scroll events are only captured after setting scroll breakpoints.
  • Changes do not apply retroactively - only events from that point forward are recorded.
