EPC (earnings per click)
EPC is how much an affiliate earns on average for each click sent to an offer: total earnings divided by the number of clicks.
EPC (earnings per click) measures how much an offer pays, on average, for each click. It's calculated as earnings ÷ clicks.
If an affiliate sent 2,000 clicks and earned €300, the EPC is €0.15. It's the simplest way to compare offers with different payouts and conversion rates.
Why it matters
A €50 CPA offer that converts 0.2% has an EPC of €0.10. A €20 CPA offer that converts 1% has an EPC of €0.20, and is the better choice. Affiliates who buy traffic compare EPC with their cost per click.

The offer catalog shows the EPC of each offer across the network for the last 7 days (when there's enough data). Smart links use the EPC to send each visitor to the best offer.
