Giving customers payment options such as PayPal and Google Checkout will help increase sales but you need to accept credit cards directly from customers if you want to maximize your sales.

The issue with not accepting credit cards directly is the drop off rate associated with third party payment providers. Just for example, a customer goes to a site and has the option of using PayPal or Google Checkout. The customer does not like using PayPal and doesn't have a Google Checkout account. The customer clicks off and completes the purchase elsewhere.
