In Google Analytics, a session is a group of hits recorded for a user in a given time period. A hit is a user’s interaction (pageview, screenview, event, transaction, etc) with your website that results in data being sent to the Google Analytics server. A user can generate one or more sessions.
All Google Analytics sessions have a expiry date. A GA session timeout can not be less than 1 minute or greater than 4 hours.
