Pay Per Click Fraud Is A Problem.

Allowing advertising on a site is one of the easiest ways to make money from a site. The owner sells some of the site’s space for advertising, and then visitors to the site click on the advertisements that they are interested in. For most site owners this is as far as it goes; if the ads make money, great, and if they do not then those ads are rotated out to try something different. However, some site owners engage in some form of pay-per-click fraud in order to get better payouts, and thus create some issues.
