What does "Available Funds" refer to in my campaign?
“Available Funds” refers to the money that has not yet been allocated to an ad group or campaign in your account. When you are creating a new campaign, you must make sure you have enough Available Funds.
How do I increase my AVAILABLE FUNDS?
You may increase your Available Funds at any time by adding more money to your account. Simply log-in to your G&R account and visit your Advertiser Dashboard. Click "Billing" on the left side of the screen.
From the "Billing" page, you can click "Add Fund+" (shown below).
