a/b testing is a method where you compare two versions of a webpage, email, or app feature to see which one works better. You show version A to one group and version B to another, then measure the difference in response rates. It's a simple, data-driven way to take the guesswork out of decisions, like choosing a button color or headline, and it's used all the time in product design and marketing.
