Refund for invalid clicks
Re: Refund for invalid clicks
With regard to invalid clicks, Google trys to automatically filter them from reports and ensure that advertisers are not charged for those clicks - in other words they try to ensure that advertisers are not charged for those clicks in the first place. If however an advertiser is charged for invalid clicks in the previous two months, they will re-credit the advertisers' account. As far as I am aware they will appear as "invalid activity" adjustments within your billing.
