Session Duration

What is Session Duration?

Session duration measures how long users spend in your product during a single visit. It's a proxy for engagement and value delivery, though interpretation depends heavily on your product type.

Longer isn't always better. A 30-minute session in a learning app is great. A 30-minute session to complete a simple task suggests friction.

Why Session Duration Matters

Session duration indicates engagement depth. Combined with session frequency, it shows total time invested in your product. Time invested correlates with switching costs and retention.

Dramatic changes in session duration signal problems or improvements. Sudden drops might indicate bugs or UX issues. Increases after feature launches suggest added value.

Using Session Duration

Segment by user journey stage. New users might have longer exploratory sessions. Power users might have efficient short sessions. Track alongside task completion to understand if time is productive or frustrated.

Weekly engagement data:

• Total session time: 50,000 minutes
• Total sessions: 10,000

Average Session Duration = 50,000 ÷ 10,000 = 5 minutes

Users spend 5 minutes per visit. For a productivity tool, this might be short. For a checkout flow, it might be too long.
