Scroll depth
Understand how scroll behavior reveals whether important content and calls-to-action are actually being seen, and how to use this information to refine page structure and the hierarchy of your content.
What scroll depth actually measures
Simply put, scroll-depth is how far "deep" a visitor scrolls on a page on your website. This is typically shown as a percentage of the total page—25%, 30%, 90%, etc.
Alternatively, you may see scroll depth represented as the percentage of visitors who reached a specific section of a page; 10% of users may have scrolled to the footer.
It's important to note that scroll depth is not a measure of user engagement or their attention within your website. Rather, it should be used to evaluate the reach of content on a given page—and be used to prioritize important an impactful sections where their reach is maximized.
Why scroll depth matters
Scroll depth should be used to evaluate whether content below the fold is ever being seen. Use scroll depth to help prioritize where to place key information and calls-to-action.
