Scroll Tracking
A practical CRO method for understanding content visibility, scroll depth, and where users lose interest.
How to use scroll tracking to measure how far users scroll, what content gets seen, and where engagement drops away.
What it is
Scroll tracking is a quantitative UX and CRO method used to measure how users move vertically through a page or screen.
It captures how far users scroll, where they stop, and how much of the content they see.

Scroll tracking is useful when the key question is whether content is being seen, not just whether it exists on the page.
When to use it
Use this method when content visibility and page structure matter.
It is most useful when:
It is less useful when:
Scroll tracking is often used alongside heatmaps and click tracking to build a fuller picture of behaviour.
Key takeaway
Use scroll tracking when the main question is how far users get and what content they actually reach.
How to run it
Set up properly
Be clear on the pages you are measuring, how depth is defined, and which content you care about reaching. Percentage depth on a page of varying length is not comparable between pages.
Decide whether you are measuring reach or dwell. Somebody scrolling past content quickly has technically reached it and has not read it.
Run the method
Scroll tracking answers one narrow question well: how much of a page do people actually get to. It is most useful when a specific element has to be seen.
- Track depth as both percentage and pixel position, since long pages and short pages need different readings.
- Measure where people stop, and pay attention to sharp cliffs rather than gradual decline. A cliff usually marks something that looked like the end of the page.
- Analyse how many reach the elements that matter (the form, the price, the glossaryCall to ActionA call to action is a prompt that encourages users to take a specific action.Open glossary term) rather than the page average.
- Segment by device and glossaryTrafficTraffic refers to the number of users visiting a website, app, or digital product over a given period.Open glossary term source.

Capture and make sense of it
The value comes from knowing what gets seen. Look across the glossaryDataData is raw, uninterpreted information collected and stored so it can be analysed, processed, or used to inform decisions. On its own it carries no meaning; context and interpretation are what make it useful.Open glossary term to identify:
- Where most people stop, and what sits immediately above that point
- Sections that are rarely reached at all
- Differences between devices and user groups
