What are Sessions?
A Session, sometimes called a Visit, is the set of interactions, or web requests, made within a given time frame by a single user visiting a specific website. A single Session often contains multiple activities, such as page views, events, or transactions. In web analytics, a session is either capped by exiting the website or by a period of user inactivity.
