A session is a visit to your website or app from a single visitor. It consists of events like page views, downloads, outlinks, custom events, goal conversions, ecommerce conversions, and so on. A single user can open multiple sessions, which can occur on the same day or over several days, weeks, or months. Once one session ends, a new session can start.

There are a few scenarios that lead to the splitting of one session:

  • Time-based expiration, which happens after 30 minutes of inactivity.
  • Campaign change, which occurs when a user arrives through one campaign, leaves, and then returns through a different one.
