Reading Results and Applying a Winner
Interpret confidence and conversion lift, then roll the winning variant out to everyone.
Overview
As an experiment runs, Prism reports progress and a recommendation. Once a winner is clear, you can apply it.
How to read results- Open the experiment to see days running, sessions exposed, and the confidence score.
- Compare the conversion rate of control and treatment.
- Read the recommendation banner, which tells you whether the treatment won, the control won, or it is too early.
- If the treatment won, click Apply winning settings to roll it out to all shoppers.
- Archive completed experiments to keep a record.
Tip: Wait for the recommendation to call a winner before applying. Ending too early risks acting on noise.
