What is Average Session Duration?
Average session time is the average amount of time users spend during one visit or session on a website, app, product, or platform.
Average Session Duration Explained
Average session time shows how long people usually stay when they use something.
A session starts when someone opens a website or app and ends when they leave or stop being active.
For example, if one person spends 2 minutes, another spends 4 minutes, and another spends 6 minutes, the average session duration is 4 minutes.
This metric helps teams understand whether users are spending enough time to read, explore, complete actions, or get value from the product.
