What is it?

Multivariate testing is an experimentation method used to evaluate the combined impact of multiple variables and their variations within a single experience. Instead of testing one change at a time, multivariate testing assesses how different elements interact with each other.

It is most commonly used when traffic volume is high and interactions between elements are expected to matter.

Examples in Action

• Testing combinations of headlines, imagery, and calls to action
  
• Evaluating multiple layout and content permutations simultaneously
  
• Understanding interaction effects between page elements
  
• Optimising complex templates with many variables
  

Typical Outcomes / Results

• Deeper insight into how elements work together
  
• Identification of high-performing combinations
  
• More efficient learning when traffic allows
  
• Increased complexity in setup and analysis
