How can I identify which changes actually improved my conversions?

As an e-commerce manager, I'm constantly running A/B tests and making website changes, but I struggle to definitively understand which modifications genuinely impact my conversion rates. I need a systematic approach to measuring the true effectiveness of my optimization efforts, separating meaningful improvements from random fluctuations. My goal is to develop a data-driven method that helps me confidently attribute conversion changes to specific strategic modifications while avoiding misinterpretation of results.
