Metrics
EPC
Earnings per click — offer-side revenue divided by clicks.
EPC (earnings per click) is what an affiliate publisher makes per click sent to an offer. Networks publish EPC averages on offer cards (e.g. ClickBank EPC, MaxBounty EPC). EPC is asymmetric — top publishers can get 3–10× the listed EPC due to better landers and segmentation. Don't trust network-listed EPC at face value.
Formula
EPC = revenue / clicks
Example
ClickBank offer card shows $1.84 EPC. Actual EPC on a niche-specific advertorial → VSL funnel: $4.20. The card averages every affiliate sending raw banner traffic.
