What is Session?
A session represents a continuous period of user activity on your site or application. It groups together all pageviews, clicks, and events that occur during a single visit into one logical unit.
Sessions typically end after a period of inactivity (commonly 30 minutes) or at midnight. When a user returns after the timeout, a new session begins. This grouping helps you understand visit-level behavior: how long users stay, how many pages they view, and what they accomplish per visit.
Session data is essential for calculating metrics like bounce rate, pages per session, and average session duration — all key indicators of user engagement.
Example
A user visits your marketing site, reads two blog posts, visits the pricing page, and then leaves. All of these interactions are grouped into a single session lasting 8 minutes with 4 pageviews.
