A/B test

An A/B test is a method used to compare two versions of something—like a webpage, app, or email—to see which performs better. You create two versions (A and B), show them to different groups of users, and then measure which version achieves your goal more effectively, such as more clicks or sales. This process helps make data-driven decisions, ensuring improvements are based on evidence rather than guesswork. A/B testing is widely used in marketing and product design to optimize user experience and outcomes.
