What is Earnings Per ClickEPC?

EPC (Earnings Per Click) is the single most useful number for comparing offers: total earnings divided by total clicks. It folds conversion rate and payout into one figure, so a €20 CPA that converts at 5% (EPC €1.00) is directly comparable to a €5 CPA that converts at 30% (EPC €1.50).

It tells an affiliate which deal is worth sending traffic to, and it tells a brand whether their offer is competitive for the traffic it's getting.

PayTandem shows EPC on every deal and benchmarks it against the median for that niche, so a creator learns whether their number is good for their vertical — not just in the abstract.
