What do you mean by session?
A group of interactions each user takes within a given time frame on a particular website is termed as a session. The default time frame provided by Google Analytics is 30 minutes. Sessions combine all the acts performed by the user in that particular time frame. It may include browsing pages, downloading resources, purchasing products, registering, filling the form, etc before leaving the website. Session metrics are a suitable way to report “visits” and “active users” on a website.
