Google does detect click fraud, but does not prevent it. Instead, Google will give back credit to your account days after the fraud took place and only after you claim it. The immediate result would be that your ad budget would be exhausted and your ad will not be online for hours or even days. In addition, Google’s click fraud characteristics are identical for all advertisers.
While 5 clicks from the same IP address in a period of a day is completely normal for one advertiser, another might see this as nothing but click fraud. ClickBrainiscs will keep your ad online and will configure the service to suit your business needs.
