Scroll Depth measures how far down a webpage a visitor scrolls. It’s a good way of seeing whether people are engaging with your content. Are they just skimming the top, or are they scrolling all the way to your CTA at the bottom?
For marketers, Scroll Depth helps spot where attention drops off. If users stop halfway, it might mean your content is too long, your design is distracting, or your CTA is buried too far down. Optimising for better Scroll Depth often leads to more conversions.
