In affiliate marketing, CPC and CPA are two ways to measure how you pay for advertising. CPC, or Cost Per Click, means you pay every time someone clicks on your ad, no matter if they buy anything or not. It's good for getting traffic to a website, but it doesn't guarantee sales. CPA, or Cost Per Action, means you only pay when someone completes a specific action, like making a purchase or signing up for something. This is often preferred because you're paying for actual results, not just clicks. CPC can be cheaper upfront, but CPA might save money in the long run since it focuses on conversions. Choosing between them depends on your goals and budget. If you want more control over costs, CPC might be better. But if you're aiming for sales, CPA could be the way to go.
