Understanding Multivariate Testing: Core Concepts and Essential Features
What is Multivariate Testing?
Multivariate testing evaluates multiple variables simultaneously to identify the optimal combination for improving user engagement or conversion rates. Unlike A/B testing, which compares two versions of a single element, MVT assesses interaction effects among several elements, providing deeper optimization insights.
