Split testing (also known as A/B testing) is a method of comparing two versions of a webpage or app against each other to determine which one performs better. Split testing is essentially an experiment where two or more variants of a page are shown to users at random, and statistical analysis is used to determine which variation performs better for a given conversion goal.
