Best payment option for Facebook ads. However, there are some things to consider when making a decision. One thing to keep in mind is that Facebook prefers payments made through its own system, Facebook Ads Payments. This system allows you to pay for your ads with a credit card or PayPal and then have the money deducted directly from your account. This makes the process simpler and more efficient than other payment options. Another thing to consider is that payments made through PayPal can sometimes take longer to process than those made with a credit card. If you're looking to get your ads up and running as quickly as possible, this may be something worth keeping in mind.
