Session Replay Analysis
A practical CRO and UX method for watching real sessions and spotting friction in detail.
How to use session replay analysis to uncover hesitation, usability issues, and behavioural patterns that analytics alone cannot show.
What it is
glossarySession RecordingSession recording captures a user's real interactions with a product (clicks, scrolls, hesitations, and navigation) for review afterwards. It shows genuine behaviour in genuine conditions, without any ability to ask why.Open glossary term analysis is a quantitative UX and CRO method used to review recordings of real user glossarySessionA session is a single period of user interaction with a product, from entry to exit within a defined timeframe.Open glossary term to understand glossaryBehaviourBehaviour refers to how users interact with a system, including actions, patterns, and responses.Open glossary term on a website or app.

Session replay analysis is most useful when you need to see the behaviour behind the numbers, not just the numbers themselves.
When to use it
Use this method when you need to understand glossaryBehaviourBehaviour refers to how users interact with a system, including actions, patterns, and responses.Open glossary term in detail.

Session replay analysis is often used alongside funnel analysis and usability testing to connect behaviour with data.
Key takeaway
Use session replay analysis when you need visual evidence of where users hesitate, struggle, or abandon a journey.
How to run it
Set up properly
