Click Fraud

The imitation of clicking on web advertisements to increase ad revenue for the Web site owner

Click fraud appears in the context of pay-per-click advertising, where an advertiser on a Web site is charged a small amount each time a visitor clicks on the ad, thus generating revenue for the Web site owner. Click fraud is when a person, automated script, or some computer program tries to imitate a genuine user in order to increase the number of clicks, thus generating illegal revenue for the Web site owner.

"Competitive click" is a method of click fraud with the intent of depleting a competitor's advertising budget. Click fraud is a serious issue resulting in many lawsuits. Click fraud is expected to reach $1.6 billion in 2008, an increase of over 45 percent from the current value.

You should be concerned about click fraud in the following cases:

1.)You publish a Web site and allow advertisers to run ads on it under a pay-per-click arrangement. In this case, you should take precautions that click fraud is not happening on your Web site, or you could be held liable.

2) You advertise on a Web site. In this case, you should avoid advertising on Web sites that are unprotected from click fraud.
