A/B testing is a controlled experiment where you show two versions of a webpage, email, or feature to different segments of users at the same time to see which one performs better on a specific metric, like click-throughs or sign-ups. It takes the guesswork out of optimization by relying on actual user behavior rather than opinions, meaning you can make data-driven decisions about changes, from button colors to headline copy, and confidently roll out the winning variation.
