Definition
Earnings per click, or EPC, estimates how much commission a partner earns for each click sent to the merchant. It is usually calculated as total commission divided by tracked clicks over a defined period.
B2B SaaS context
In B2B SaaS, EPC can be misleading when the sales cycle is long or revenue is recurring. A low early EPC may become attractive once trials convert, invoices renew and expansion revenue is counted.
Operator note
Segment EPC by partner, channel and cohort age, and filter non-human clicks before using the metric to judge program quality or commission competitiveness.
