What do u mean by Session? Session means when a user/visitor visits your website and interactions done by a user such as social interactions, page views, events, e-commerce transactions in a single time frame.


                                                 You can understand session as a container for actions a user takes on your site.



A single user can open multiple sessions during those sessions can occur one a single day or over a period of time of several days, weeks or months. As a session ends a new session can start on the next visit.

There are two methods by which a session ends
1)Time-based expiration
a)After 30 min inactivity
b)At midnight
2)Campaign change

Time-based expiration :

How long the session lasts?

A session lasts for 30 mins of inactivity. But you can adjust this limit from a few secs to several hours.
example: Suppose a user visit your site and leaves your site and comes after 30 mins again then it will be called as 2 sessions as 2 visits by the user. But if the user continues  and interacts with the website then it will be called as 1 session
