How can I tell which traffic source (e.g., Instagram, Google, Email) brings the most valuable customers?

I'm struggling to understand which marketing channels are truly driving value for my e-commerce business. While I can see basic traffic and conversion metrics, I want to dig deeper and identify not just which sources bring the most visitors, but which ones generate customers with the highest lifetime value, average order value, and repeat purchase rates. I need a comprehensive strategy to track, analyze, and optimize my marketing efforts across different traffic sources.
