How do you lower nCAC on Meta?

The fastest way to lower New Customer Acquisition Cost (nCAC) is to fix Optimization Pollution by feeding Meta a "New Customer Purchase" signal rather than a general purchase event. By using Signal Architecture to filter out repeat buyers from the optimization loop, brands typically see an $18-35\%$ reduction in nCAC because the algorithm stops "drifting" toward existing customers.

Customer Lifetime Value (LTV) is an often overlooked metric for ecommerce companies. That's not a bad thing though because it gives an advantage to brands who are using it properly to optimize cold traffic. Their competitors don't even know what they are missing!
