Multivariate testing is a technique for altering multiple variables to test a hypothesis. The aim of multivariate testing is to figure out which combination of variations out of all the possibilities performs the best. Combinations of changeable components make up websites and smartphone applications. A multivariate test involves modifying several elements at once, such as an image and headline. Three picture variations and two headline variations are combined to produce six material variations that are checked simultaneously to find the winning variant.
