Session

A visit to a website.

The audit definition of a session is more precise, because it details exactly what auditors will count as valid traffic. The IFABC standard describes it as "a series of page impressions served in an unbroken sequence from within the site to the same user." A session begins when a valid user connects to a site, continues while page impressions are served in a continuous sequence from within the site, and ends when the user leaves the site. Effectively, the event that is measured is the number of arrivals at the site by a user who was previously outside the site.

When used in the context of web development, a session is used to store a users details such as their name or login credentials.
