Scroll depth is one of the best indicators of content quality and user engagement. Users who scroll deep are more likely to convert — and knowing where users stop scrolling helps you optimise page layout. We implement precise scroll tracking using the Intersection Observer API (more accurate than percentage-based scroll) or configurable percentage thresholds, pushing data layer events at meaningful scroll milestones with page context data.
