How to calculate Average Session Duration

A website gets 10,000 sessions in a month. All together, these sessions add up to a total session duration of 400 hours, or 24,000 minutes, in that same month. Therefore, for that month, the Average Session Duration is 2.4 minutes.

More about Average Session Duration

A session is defined as a period of activity on a website that starts when a user enters the website and ends with either inactivity or exiting the website. The more time a user spends on your website, the higher are the possibilities for them to return, sign up, purchase a product, and generally develop a relationship with a business.

By tracking the Average Session Duration, you gain the ability to understand, on average, how much time people are spending on the content across your website. If this number is on the lower side, it may indicate that your website or content is not interesting or difficult to use. In general, several benchmark studies agree that the average session lasts between 2 – 4 minutes. Pages that exceed 2 – 4 minute Average Session Duration likely provide exceptional value to the reader, either in the form of valuable content or information highly relevant to the reader.

Individual session duration is calculated differently from Average Session Duration. While Average Session Duration is calculated as total session duration by number of sessions, individual sessions are recorded based on engagement hits. An engagement hit is essentially an event you track that has been triggered. For example, say you track video starts as an event. The individual session is started only when a user plays a video for the first time. If there are no engagement hits that take place during the entire session, individual session duration is calculated based on (non-interaction) hits instead.
