"I have a ton of experience in running A/B and multivariate tests. I believe that this is at the heart of what I do as a growth marketer! After determining what should be tested, I use tools like Optimizely to help me create and run the experiments. And I recognize the importance of making sure that nothing skews my results. For example, I know that a viral campaign can impact how much traffic visits a webpage, so to prevent this contamination I usually test paid traffic from Google Ads or Facebook because I recognize that segmented traffic from a specific source provides more reliable insights."
