Reading these numbers honestly
EPC only means something at volume
On a few hundred clicks, EPC is mostly noise — one conversion moves it a long way. Treat it as a real number somewhere past a few thousand clicks, and compare it only between sources of similar size.
Break-even CPC is your negotiating number
It is the most you can pay per click before the campaign loses money. Take a margin off it and that is your affiliate payout — not the other way round.
These figures assume every conversion is real
They do not model fraud, duplicates or reversals. If ten per cent of conversions get charged back later, your real EPC is ten per cent lower than this — which is why the reversal rate is worth tracking separately.
