ABn Testing

What is ABn testing?

ABn testing is a type of testing where 2 or more variations of a certain element on a web page are compared with each other to understand which variation will deliver the goal of an experiment, or prove the hypothesis.

The ‘n’ in ABn testing refers to the multiple variations in the test. By contrast AB testing is a simpler test, pitching just one variation against another.

How ABn testing works

Traditionally, traffic is split in equal proportion between the experiments, for example if you have 4 experiments each experiment will have 25% of the traffic.

Traffic is also divided randomly amongst each variation, to make the sample distribution arbitrary.
