How do I measure ROI on my discount campaigns?

As an e-commerce business owner, I'm struggling to understand the true impact of my discount campaigns. I'm investing significant resources into promotions, but I can't confidently determine whether these discounts are actually driving profitable growth or just eroding my margins. I need a comprehensive approach to measuring the return on investment (ROI) for each discount campaign, including both immediate and long-term effects on revenue, customer acquisition, and overall business performance. What metrics and strategies can I use to accurately assess the financial effectiveness of my promotional efforts?
