With auto-recharge, you can help make sure that your prepay account has enough balance remaining to keep your ads running. If you don't set up auto-recharge and your balance remaining hits zero, we'll pause your campaigns and your ads will not display until you manually add more funds.
If you sign up for auto-recharge, each time your account balance reaches 20 percent of the recharge amount, we will automatically charge your primary payment method and add funds to your account.
To set up auto-recharge, you need to make sure that you are using a credit or debit card as your primary payment method.
