Click fraud involves placing ads on your website and then clicking on the links in order to generate income. Often this results in only a limited profit and fraud will not be noticed. Although fraud on a much larger scale occurs.

Scripts (small computer utilities) can be used in order to simulate the clicks. If this type of fraud is done from a single or limited number of computers (or IP addresses) within a given region, this will trigger a suspicious activity alert and so the chances are that they will be caught.

There is organized crime syndicates involved in click fraud. They use a large number of computers spread over a large geographical area in an effort to commit fraud.

This is sometimes done using computers of innocent and ignorant users, where a Trojan is installed. These zombie computers are used in this way once you click on an advertisement to simulate in order to generate income for syndicate that placed the ads.

Even a company like Google unintentionally benefits from click fraud because they also have their share of advertising revenues in their pocket. This activity compromises Adwords advertisers whose return on investment (ROI) is depleted.

There are estimates that 14 to 25 percent of all clicks on online ads are fraudulent, but Google itself claims that these figures are greatly exaggerated because they are based on faulty research.
