What a User Session is: The session of engagement or activity that a visitor with a unique IP address has on your site.
What a User Session looks like: Your testing platform will define the duration of a session (typically 20-30 minutes). If a unique visitor reaches your page, they may leave and return within your set timeframe without initiating a new session.
What to remember: If a user returns after your defined length of time, visits from a new browser, a new IP address or clears their cookies, they will start a new session.
The benefits: User sessions help reduce skewed results. A user may click back and forth between your page and another website multiple times, bloating your visitor count—sessions take this into consideration and can help give you a better understanding of the activity on your site.
