If you are referring to the payment of the clients, I am paid through PayPal. You can create your account at www.PayPal.com. Once you have the money in your PayPal, you need to add your credit or debit card so that you can withdraw the money. The account needs to be verified before money can be withdrawn.
If you're referring to Google Adsense program, then Google doesn't yet offer payments by Paypal. Google offers payments by check, Western Union, EFT and much more.
Most of the payments are from paypal except adsense payment. Google adsense is sending cheque regularly.
Always go for checks or direct deposits. There have been horror stories about Paypal and although I have not had any bad luck with them, I know some people have.
Direct Deposits are the best, directly paid into your bank. Payments have always been on time and efficient. Really great.
