Google can detect click fraud, but it does not prevent it. Instead, Google will give back the credit to your account days after the fraud took place and only after you have claimed it. The immediate results? Your ad budget will be exhausted and your ad will not appear online for hours or even days. In addition, Google’s click fraud characteristics are identical for all the advertisers.
While 5 clicks from the same IP address in a period of a day is completely normal for one advertiser, another might see it as click fraud. ClickBrainiacs will keep your ad online and will configure the service to suit the needs of your business.
