The grinch may have stolen Christmas, but it's competitors who steal your ad budget. One of the things that puzzled our click fraud analysts for quite some time was the oft-repeated pattern of a client's competitors signing up for PPCSecure within days or weeks of the client installing PPCSecure. Example: A locksmith in Portland signs up for PPCSecure, and within weeks, 3 or 4 other locksmiths from the same neighborhood also sign up. Of course, there is no way to prove any connection, but it does seem like a strange coincidence. It's like a criminal who gets caught on camera suddenly installing cameras at his own house.
