1. Artificially inflate click-through rates (CTR)
2. Consume ad budgets for advertisers
3. Illegitimately increase affiliate commissions
4. Interrupt competitor campaigns

Common sources of click fraud

Here are the common sources of click fraud:

1. Click bots: Automated programs designed to click on affiliate links repeatedly.
2. Click farms: Many low-paid workers are hired to generate fake clicks.
3. Competitors: Affiliates or businesses that click your ads to sabotage your performance.
4. Malware: Viruses installed on devices that drive clicks without users’ consent.
5. Incentivized traffic: Users clicking links for an incentive instead of interest.

Click fraud drains ad spend with paid clicks that never convert.

2. Contaminated analytics

The same IP address is clicking multiple times.

How click fraud affects affiliates and advertisers

Case study of Shawn Hogan and the $28M eBay affiliate fraud

Shawn Hogan, founder of Digital Point Solutions, ran a cookie-stuffing scheme that secretly placed eBay cookies on users’ browsers, earning him fraudulent commissions.

From the mid-2000s to 2007, he made over $28M before an FBI probe led to his 2010 indictment.

In 2014, he was sentenced to five months in prison, three years’ probation, and a $25,000 fine.

The case is a landmark example of large-scale affiliate click fraud.
