What does EPC mean in affiliate marketing?

EPC stands for 'Earnings Per Click'. It is the most important metric in affiliate marketing because it tells you exactly how much revenue you generate, on average, every time a user clicks your affiliate link. If your EPC is $1.50 and you buy ads for $0.50 per click, you are highly profitable.

What is the exact formula to calculate EPC?

The exact formula for Earnings Per Click is: Total Affiliate Commissions / Total Clicks. For example, if an affiliate offer generates $500 in commission from 2,000 clicks, your EPC is $500 / 2,000 = $0.25 per click.

Why is my ClickBank or Amazon affiliate tracking inaccurate?

Standard affiliate networks rely on third-party cookies, which are now blocked by Safari (ITP) and iOS. If a user clicks your affiliate link on an iPhone and buys later, the cookie is deleted and you lose the commission. Using a server-side link shortener like gometrify prevents cookie-stripping, recovering up to 25% of lost affiliate commissions.
