I heard about CPA vs CPS vs CPL affiliate models. What’s the difference, and which pays better?

[Daniel]

These are different ways affiliate programs pay. CPA means cost per action. You earn when someone takes a specific step like signing up or installing an app. CPL stands for cost per lead. You get paid when someone gives their contact info, like email or phone number. CPS is cost per sale, which only pays when someone actually buys something. In most cases, CPS pays more per conversion, but it's also harder to get because people must spend money. CPL and CPA are usually easier, but the payout is lower. What matters more is which one fits your traffic and audience. Some people respond better to free signups, while others are ready to buy. What model do you think works best in your case?
