What is average session duration?

It is calculated from the time between the first and last interaction in a session. The last page of a visit is hard to time, so the number is an estimate.

Long durations can mean engaging content, but they can also mean confusing navigation.

Why Average session duration matters

  • It gives a rough sense of engagement.
  • It helps compare content types.

Practical tips

  • Do not use it alone. Combine it with conversions.
  • Compare similar pages, not different page types.
