Multivariate Testing
MVT (Multivariate Testing)
An experiment testing multiple page elements simultaneously to find the highest-performing combination — for example, testing three headlines and two CTA colours in a single test. MVT can detect interaction effects that A/B testing misses, but requires 5–10× more conversion volume per variant to reach statistical significance. Best reserved for high-traffic pages where single-element A/B tests have been exhausted.
How Multivariate Testing works in practice
Full-factorial MVT tests every possible combination of variants — 3 headlines × 2 CTAs = 6 combinations, each needing statistical significance. Fractional factorial designs test a mathematically chosen subset of combinations, reducing required traffic while still identifying the strongest effects. The main practical challenge is the traffic requirement: a typical e-commerce landing page converting at 3% needs 30,000+ visitors to run a full-factorial MVT with 6 combinations at 95% confidence. For most sites, sequential A/B testing of individual elements is more practical — test headline first, apply the winner, then test CTA, then test imagery. Reserve MVT for the highest-traffic pages where interaction effects between elements are genuinely suspected.
