Getting AI conversions but want more

Conversion rate is sales divided by clicks and shows how well the audience fits the offer. EPC is earnings divided by clicks and shows what each click is really worth. Compare sources on EPC, because it includes country, plan and tier differences that conversion rate hides.

Give every source and placement its own Source ID and sub-IDs, then compare them on earnings per click over a complete period with enough conversions. Split by country and device before deciding, scale the clear winners and fix or drop the rest.
