What is Engagement Depth? Examples and Best Practices
Engagement Depth is a comprehensive web analytics metric that measures how thoroughly visitors interact with your content. Rather than counting mere page views, it aggregates signals like:
- Time on page
- Scroll depth percentage
- Clicks and other interactive events
By combining these dimensions, engagement depth reflects not just if a user landed on a page, but how much they consumed and interacted with its content. High engagement depth typically correlates with better user satisfaction, lower bounce rates, and increased conversion potential. Analytics platforms such as Plainsignal and Google Analytics 4 (GA4) provide tools and events designed to track and analyze engagement depth effectively.

Understanding Engagement Depth
This section defines engagement depth, explains its core components, and why it matters in modern web analytics.
-
Core definition
Engagement depth is a weighted measure of how users interact with a page—capturing duration, scroll, and events rather than just views.
-
Business impact
Deeper engagement often signals stronger content relevance, leading to higher conversion rates and improved SEO performance.
Measuring Engagement Depth
Overview of the metrics and calculations used to derive an engagement depth score.
-
Key metrics
Typical inputs include time on page, percentage scroll depth, number of clicks or interactions, and video or form engagements.
-
Composite scoring
Each metric can be weighted (e.g., 50% time on page, 30% scroll depth, 20% interactions) to produce a unified engagement score.
