Multivariate Testing: Multivariate testing is a technique used in website optimization to test several variations of different elements on a webpage simultaneously. The goal is to determine which combination of elements (such as headlines, images, or CTAs) leads to the highest conversion rates or other desired outcomes. By analyzing the performance of each combination, marketers can identify the most effective design and content strategy for their website. This testing method is more complex than A/B testing but provides more detailed insights on element interactions and visitor preferences.
