Webform A/B Testing, originally released in beta, is now a fully available feature that lets you test different versions of a webform against each other and see which one actually converts better, rather than guessing.
Create variants of a form with different fields, calls to action, wording, or colour combinations, and compare their performance directly.
The winning variant is decided by minimum abandonment rate, then highest complete submission rate, with the original form as a tiebreaker. You can still choose to launch a different variant yourself, even after a winner is declared, if you have reasons to prefer it.
