EPC
Average earnings per click on an offer: EPC = payouts / clicks. Networks publish it per offer as a rough guide to what the offer is worth; your own EPC on your traffic is the number that counts.
Also called: earnings per click.
A network's EPC is an average over all affiliates and all traffic types, so it hides the spread: an offer at $0.30 EPC might do $1 on native and $0.05 on pops. Use it to shortlist offers, then measure your own.
Your EPC minus your CPC is your profit per click. When that goes below zero for a placement, the placement goes on the blacklist.
