Scroll depth

Scroll depth measures how far users scroll down a webpage, indicating content engagement.


Scroll depth is a metric used in web analytics to understand how much of a webpage a user views by measuring the distance they scroll vertically down the page. It's usually expressed as a percentage of the total page height or as specific checkpoints (e.g., 25%, 50%, 75%, 100%). This metric helps in assessing content engagement and effectiveness by providing insights into how much content is being consumed by the visitors.

By analyzing scroll depth data, they can identify which parts of a webpage attract the most attention and which are often ignored. This information is crucial for optimizing webpage layout, content placement, and improving overall user experience. Scroll depth tracking is particularly useful for long-form content, landing pages, and blogs, where understanding user engagement at different intervals can inform content strategy and design decisions.
