Test will not launch or results look wrong

Fix launch checks that block a test, and the reasons results say we cannot trust the numbers: embed, pixel, visitors and traffic split.

Launch is blocked

The launch sheet lists what needs attention, each with a fix button.

Results say we cannot trust the numbers

  • The app embed is off, or the tracking pixel is disconnected: fix it with the button in the verdict.
  • No visitors have been counted for several hours: check that your storefront loads.
  • The traffic split is far from what you set: see Guardrails, watch-outs and traffic split.

Results refresh about every hour, and orders can take up to an hour to appear.
