How do I track the long-term impact of CRO changes?

I'm struggling to understand how to effectively measure and track the long-term impact of my conversion rate optimization (CRO) efforts. While I can see short-term changes, I want a comprehensive approach to understanding how my strategic improvements affect overall business performance over time. I need a systematic method to track these changes, validate their effectiveness, and demonstrate their value to stakeholders beyond immediate conversion metrics.
