Session duration
The total amount of time a visitor spends on your website during a single session, measured from their first pageview to their last interaction.
Session duration (also called time on site) measures how long visitors spend on your website during a single visit. It is calculated as the time between the first and last recorded interaction within a session.
Longer sessions generally indicate that visitors find your content valuable and are exploring your site. Context matters though: a quick session on a simple tool or FAQ page might indicate efficiency rather than disengagement.
Traditional analytics struggle to accurately measure session duration because they can't track time spent on the final page of a session (there's no subsequent pageview to calculate against). Some tools address this with heartbeat pings or exit tracking.
Factors that influence session duration include content quality, site navigation, page load speed, and whether the content matches visitor intent. To improve session duration, focus on creating engaging content, internal linking, and clear user journeys.
Compare session duration across different traffic sources and landing pages to understand which channels bring the most engaged visitors.
