Earnings Per Click — total affiliate earnings divided by total clicks, showing publisher revenue efficiency.
In Plain English
How much money a publisher earns, on average, for every visitor they send your way — the number publishers use to decide whether your program is worth promoting.
How Xark Uses This
EPC is the single most important signal publishers use to rank programs in their content calendars. Xark benchmarks EPC against category averages and uses it in every publisher outreach email — quoting a strong EPC alongside commission rate drives 2–3× higher reply rates. When program EPC drops below category benchmark, we investigate landing page CVR and AOV before touching the commission structure.
Example
A program that paid out $1,500 in commissions across 10,000 clicks has an EPC of $0.15 — in line with consumer electronics benchmarks.
