What's the best way to track revenue attribution to different CRO changes?

As an e-commerce manager, I'm struggling to accurately track which specific conversion rate optimization (CRO) changes are directly contributing to revenue increases. With multiple experiments running simultaneously and various elements being modified across our website, it's challenging to isolate the impact of individual changes. I need a systematic approach that allows me to measure the precise revenue contribution of each CRO modification, understand its statistical significance, and make data-driven decisions about future optimization strategies.
