What an A/B test does

A/B testing splits eligible visitors between versions so you can compare outcomes. It is useful when the changed variable is meaningful and the test receives enough observations.

Good test candidates

Offer framing, headline clarity, page structure, form length, pricing presentation and CTA language can all be valid when tied to a specific hypothesis.
