The Effective EPC, or eEPC for short, is a key metric in affiliate marketing. It shows the average earnings per click on an advertiser's link. Not only does it include direct income from confirmed sales, but also potential future earnings from recurring payments or follow-up commissions. This way, the eEPC offers a more realistic and comprehensive view of the performance of an affiliate link or campaign.

The eEPC concept helps you compare the efficiency of different affiliate offers more effectively. It reveals how profitable a click really is for the publisher in practice — considering not just short-term but also long-term returns.

In practice, this metric makes it easier to choose the best advertiser programs and helps you allocate your marketing resources more precisely. This strengthens strategic focus and supports sustainable growth in affiliate marketing.

A well-calculated eEPC forms the foundation for informed decisions and successful affiliate strategies by looking beyond mere short-term numbers and making the true value creation per click visible.
