What fees are there for using Google Ads?

You get to enter your maximum daily budget, so what you pay is entirely up to you. You pay only when someone clicks on your ad.

We check at the end of the month how much of your budget was used, and bill you for this plus a 20% service fee. If you have an ad credit balance on your account, the service fee will be charged based on the budget you spent, and then your ad credit balance will be applied.
