What does EPC mean in affiliate marketing?
How the number is calculated
Add up the commissions earned from a link or page over a set period, then divide by the clicks it received in that same period. If a page earned a modest amount from a few hundred clicks, its EPC is simply that total divided by the click count. Use the same time window for every comparison so the figures line up.
Many affiliate dashboards report EPC automatically, but the definitions can differ. Check whether the figure counts pending commissions or only approved ones.
Using EPC to make decisions
EPC lets you compare a product review with a comparison page, even when their traffic levels are very different. A page with fewer clicks and a higher EPC may deserve more internal links or better content. A page with many clicks and a low EPC may need a stronger offer or clearer recommendations.
- Compare pages over the same date range
- Check whether pending sales are included
- Read EPC alongside conversion rate
- Watch for seasonal swings in the numbers
Limits of the metric
EPC does not show profit, because it ignores hosting, tools, and your time. A few large sales can also distort the figure for a short period. Treat it as one signal among several rather than a final score for a page.
Common mistakes
- Comparing EPC across different date ranges and drawing firm conclusions.
- Treating EPC as profit and forgetting the costs of running the site.
