What are Sessions?

A Session, sometime 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 will often contain multiple activities such as page views, events, or transactions. In web analytics, a session will either be capped by exiting the website or by a period of user inactivity.

Though Sessions is a good metric to understand true website usage, it's useful to look at Unique Users as well.
