When our system detects invalid clicks on your ads, we automatically filter these out of your reports so that you're not charged for them. However, you still have the option to view invalid click data if you'd like to. See the section below about "Viewing invalid click data" for information on how to view invalid click data in your account.
If we find invalid clicks that have somehow escaped our automated detection in the past two months, we'll give you credit for these clicks. To view these credits for invalid clicks, click the Billing tab. Any invalid click credits you've received will be labeled "Invalid activity" on the transaction history page and will be credited to you.
