Sessions will tell you that someone came to your website or app, spent a bit of time visiting pages and then left your website. Sessions are a collection of requests from a user on your website, it works quite simply as described below:
- Every other request that your user makes is attached to a unique session id, everything the user does and the pages they visit are collected and stored against this unique id.
- When the user eventually leaves your site the unique session id is used to stitch all the interactions together into a data set that represents the total session history of that users visit to your website.
- Then when you use your analytics tool, such as Google Analytics and run a report for any given time period your tools total sessions is the count of all the sessions during that given time period.
