An A/B/n test is an A/B test with more than two variants. A/B/n testing is an online technique used for comparing one control web page or app screen to more versions of the original, with the purpose of determining the best performing variant.

The variations can be obtained by changing minor elements of the original, such as a headline or a button, but can also include major changes, such as a complete redesign of the page or app screen. A/B/n testing is used in website or app optimization and should lead to better conversion rates.
