It seems the best adult affiliate programs out there offer 2 choices: 1) getting paid a set amount for each FREE or 2-Day Trial sign-up; 2) getting paid a commission for each paid-in-full monthly subscription.

Both methods seem enticing. With the first choice, you're guaranteed a set amount even if the customer chooses not to renew. And since it's FREE (or a very low fee), it's an easier choice for most customers.

With the second choice you get paid more, but it's a tough sell to customers. Also, how many paying customers actually renew, and how long do they last?

Does anyone have any ideas on which method is better?

Thanks in advance.
