How do I calculate the ROI of different CRO investments?

As an e-commerce manager, I'm struggling to understand how to effectively measure and compare the return on investment (ROI) for different conversion rate optimization (CRO) strategies. I want to make data-driven decisions about where to allocate my marketing budget, but I'm finding it challenging to create a standardized method for calculating and comparing the financial impact of various CRO initiatives. What framework can I use to systematically evaluate the performance and profitability of different optimization efforts?
