A/B/N testing is a method of testing multiple versions of a web page or mobile app against each other to determine which performs best.
A/B/n testing is an extended version of A/B testing, in which two versions of a page (a version A and version B) are tested against each other. With an A/B/n test, more than two versions of a page are compared against each other at once. “N” refers to the number of versions being tested, anywhere from two versions to the “nth” version.
