What is multivariate testing?
Multivariate testing is a method of testing several changes on a page at the same time, such as headline, image, and button, to find which combination performs best. It also shows how the elements affect each other.

How multivariate testing works
You choose the elements to vary and a few options for each. A full-factorial test shows every combination to different visitors, then measures which combination produces the most conversions.
Three headlines and two images, for example, make six combinations.
Multivariate testing vs. A/B testing
An A/B test compares two complete versions and needs less traffic. A multivariate test splits visitors across many combinations, so each one gets a smaller share and the test needs far more traffic to reach a clear result.
When to use it
It suits pages with high traffic where you want to learn how elements work together. For most sites, a series of focused A/B tests is the more practical choice.
Common questions
How much traffic does multivariate testing need?
A lot more than an A/B test, because traffic is divided among every combination. If your page gets limited traffic, stick to A/B testing.
What can you test in a multivariate test?
Any page elements, such as headlines, images, button text, layout, or form fields. Keep the number of elements low so the number of combinations stays manageable.
What is the advantage of multivariate testing?
It shows which elements matter most and how they interact, which a one-change test can't. That helps when several parts of a page may influence each other.
Is multivariate testing better than A/B testing?
Neither is better in general. A/B testing is simpler and faster, while multivariate testing gives more detail when you have the traffic to support it.
