Tool

Most pre-launch pages do not have the traffic needed for a decisive A/B test.

Before running a live experiment, estimate whether you can collect enough conversions to detect a realistic lift. If not, use a synthetic comparison to choose the better candidate first.

Test a page

Inputs that matter

  • Current conversion rate.
  • Minimum detectable effect worth acting on.
  • Daily visitors to the page.
  • Acceptable test duration.
  • Risk tolerance for false positives and false negatives.

Decision rule

If the test would take longer than the page or campaign will remain stable, run a synthetic variant comparison first. Then reserve live traffic for the strongest candidate.
