Conversion experiment lab
Improve the path to a confident decision.
Visitors are assigned consistently to one version of each active experience. We measure useful actions—not time on page—and keep safety, rankings, disclosures, and editorial conclusions outside the experiment.
50 / 50 assignment
Stable per anonymous browser session
Visible exposure
A view counts only when the tested surface appears
Protected truth
Specs, scores, safety, and prices are never varied
Live results
Decisions wait for enough evidence.
Conversion rates use unique exposed sessions. Relative lift is directional until every variant reaches the published minimums; no experience is promoted automatically.
Decision rules
Conversion never outranks trust.
Run both variants concurrently so seasonality affects them equally.
Use unique sessions, not raw clicks, as the comparison denominator.
Review mobile and desktop behavior before adopting a challenger.
Keep a full control history and change one material idea per test.
Do not test misleading urgency, fake scarcity, hidden disclosures, or unsupported price claims.
Stop an experiment immediately if it harms accessibility, safety comprehension, or site reliability.
