Major PPC companies such as Google and Yahoo decline to quantify the scope of click fraud. However, some estimate click fraud range from a few percent to more than twenty percent. Click fraud occurs when a person, automated script, or computer program imitates a legitimate user of a web browser clicking on an ad. These clicks are done for the purpose of either to drain competitor's marketing budget or generate advertising income.



Who Commits Click Fraud?

Business Competitors:

Competitors of a business try to drain opponent's pay per click (PPC) marketing budget by clicking on their PPC ads deliberately. They may click themselves, have friends or employees click or use software to click the ads. Advertiser's PPC ad will automatically stop showing on the ads listing if the daily budget of PPC campaign is set. Competitors can then bid at a lower price for the same position.

Web Publishers:

Many web publishers are making money by showing ads syndicated by PPC companies such as Google, Overture, Yahoo and etc. They earn money from clicks on these ads. Some publishers fraudulently generate clicks on their own ads in order to make money or make more money quickly.

Networks of Clickers:

There are few networks of clickers organized by fraudsters to click PPC ads. In these networks, each member is asked to click on other member's PPC ad in return for other members to click on his ad.

Bad People:

Plain old mean people know that they can easily drive advertiser's marketing budget to the roof or kick publishers out of the PPC advertising business by clicking on their PPC ads deliberately and frequently.

PPC companies such as Google and Yahoo do not tolerate click fraud and they have sophisticated anti click fraud systems in place to fight click fraud. These systems will monitor incoming clicks and then discard fake clicks. However, these systems relied on unrevealed artificial intelligent click fraud patterns are far from perfect and sometimes not effective. Besides, the current systems provide no protection for the publishers. These systems do not alert the publishers for click fraud activities happened on their websites. Publishers could easily be banned from the PPC advertising program for click fraud activities which they did not commit.
