Which test tube has the magic elixir in it? A, B or C?
Whoa there, easy Tiger! Why would you say such a thing? Well, first of all let me qualify that statement.
Both forms of testing have their individual merits and can be used for different situations. A/B is quick and simple and can tell you which page works better for your target audience. Multivariate can test a multitude of options and variants to come up with the absolute peak performer out of hundreds of potential landing page element combination’s. (However, there are certain restrictions that mean that Multivariate (MVT) isn’t even statistically viable until you have masses of traffic).
Note: if you’re unsure of the differences between A/B Testing & Multivariate Testing you should read this post on the differences for clarity.
