QA and launch

The checks to complete before, at, during and after launch, from browser-device QA and tracking to the day-one sample ratio check and safe ramping.

• Run a pre-launch QA pass on the browser-device pairs that carry your revenue, including tracking and consent
• Check the traffic split for a sample ratio mismatch with a chi-square test
• Apply the rules for ramping, stopping early and closing a test properly
