MVT test, also known as multivariate testing, is a method used to compare and analyze multiple variations of a website or app design in order to determine which one performs the best. This type of testing allows businesses to make data-driven decisions on which design elements, such as layout, color, and content, are most effective in achieving their desired goals, such as increasing conversions or improving user experience. By testing multiple variations simultaneously, MVT testing provides valuable insights into user behavior and preferences, helping businesses optimize their digital presence for maximum impact.
