What is AB Testing?

AB testing or A/B testing is a scientific way to compare the performance of two versions of a web page called A and B. The differences between the two versions can be found on: the design, the content, the structure of the site. The purpose of this comparison is to identify which one converts the most.

Part of the users will be directed to version A, and another to version B. This distribution is random. Statistical analysis based on indicators such as the rate: conversion, clicks, purchases, subscription, etc. will allow a conclusion to be drawn about the effectiveness of each of the versions.

A/B testing is a procedure practiced in marketing to identify the best version of digital content according to a defined objective. It may happen that several versions are presented in order to undergo an evaluation, this is called A/X testing.

Origins of A/B testing

This is a process that appeared long before the Internet, since the concept is to compare two versions of the same product to determine the most efficient. In the 1920s, the British biologist and statistician Ronald Fisher was the first to highlight it with mathematics. This has contributed to a great advancement of the scientific world. This principle then developed into medicine with clinical trials.

A/B testing was taken up again in marketing in the 1960s. However, as we know it today, A/B testing has existed since 1990. It proved itself very quickly. The development of digital technology and the democratization of the Internet has increased the scope of performance testing possibilities tenfold. The technological evolution with the different tools available facilitates the design of tests and the analysis of results.
