What is a Session?
A group of user interactions on your website within a given time period.
Understanding Session
A session is a group of user interactions with your website that take place within a given time frame. In analytics platforms, a session typically ends after 30 minutes of inactivity or at midnight. One user can have multiple sessions.
Sessions are a foundational unit for measuring website engagement and performance. Key session metrics include pages per session (engagement), average session duration (time spent), bounce rate (single-page sessions), and conversion rate (sessions resulting in goals). Understanding session behavior helps you identify user intent patterns, content effectiveness, and conversion barriers. In GA4, the session definition has been updated to better handle single-page applications and cross-device behavior.

Why is Session important?
Sessions provide the context for understanding user behavior—they show not just isolated page views but how visitors navigate through your site and interact with your content. Session-level metrics reveal engagement quality and help identify friction points in the user journey. However, the shift to GA4's event-based model means session metrics are less central than in Universal Analytics.
