Split Testing (A/B Testing)

Testing two versions of a page to see which performs better.

Split testing, also called A/B testing, is the practice of comparing two versions of a web page (or element) to determine which one achieves a better outcome. One group of visitors sees version A, another sees version B, and performance is measured against a defined goal (e.g., form submissions, clicks, purchases). Split testing removes guesswork and enables data-driven design decisions.
