Scroll Depth

Why Scroll Depth matters

A page can only work if people reach the parts that matter. Scroll depth shows where visitors stop, so you can tell whether your key message, proof or call to action sits where most people will see it.

Microsoft Clarity shows this visually with scroll maps, which color the page by how many visitors reached each part. GA4 can also record a scroll event when visitors reach about 90 percent of a page.

How to read it

There is no universal target, because depth depends on the page. Long articles will naturally have lower average depth than short landing pages.

Look for sharp drop-off points on a page, since they often show a place where the layout looks like the end of the page or where the content loses interest. Check mobile and desktop separately, as page length and behavior differ.

How to improve it

• Put the most important message and the main call to action high on the page.
• Avoid layouts with large blank gaps that look like the end of the page.
• Use headings and visual breaks to pull readers down the page.
• Check scroll maps on mobile and fix pages where most visitors stop early.

Common mistakes

• Assuming everyone should reach the bottom of every page.
• Placing the key call to action only at the bottom.
• Reading the average without checking where the sharp drop-offs are.
• Ignoring differences between mobile and desktop.
