What metrics should I focus on when evaluating test results?

As an e-commerce business owner, I'm running multiple A/B tests and feeling overwhelmed by the amount of data. I want to understand which metrics truly matter when evaluating test results, so I can make data-driven decisions that improve my conversion rates and overall store performance. I need a clear framework for interpreting test outcomes beyond just surface-level numbers, ensuring I'm drawing meaningful insights that can drive strategic improvements in my online store.
