A single user can open multiple sessions. Those sessions can occur on the same day, or over several days, weeks, or months. As soon as one session ends, there is then an opportunity to start a new session. There are two methods by which a session ends:
- Time-based expiration:
- After 30 minutes of inactivity
- At midnight
- Campaign change:
- If a user arrives via one campaign, leaves, and then comes back via a different campaign.
