You Pay Commissions But Get No Orders. What’s Going On? You Might Be a Victim of Affiliate Fraud.

Every time you run another ad or marketing campaign, you run the risk of getting back less than what you spent.

Running the occasional unsuccessful campaign is the norm. After all, not every marketing dollar is going to yield a positive return. When it becomes an issue that needs immediate attention, though, is when your campaign’s poor performance is due to fraud.

For example, you may set up an affiliate marketing campaign and pay commissions to third-party partners for generating conversions. But, you end up getting no new customers.

A poorly planned campaign probably isn’t the culprit. Instead, fraudsters posing as affiliates may be straight up stealing your commissions through a practice known as affiliate fraud.

Chapter 1

What is Affiliate Fraud?

Affiliate fraud occurs when third-party affiliate marketers or publishers use deceptive, unethical, or abusive tactics to generate commissions, regardless of whether you actually receive any sales.

Affiliate fraudsters game the system through various means. They may send over bad traffic, purchase your products themselves (and then file chargebacks later), or create fake accounts to exaggerate the extent of their audience.

Common Affiliate Fraud Tactics

Affiliate fraudsters gear their tactics to exploit the payment model that you use to compensate your referral partners. For example, fraudulent publishers may send bad traffic to your site based on whether you compensate them via a cost-per-impression (CPM), cost-per-click (CPC), cost-per-lead (CPL), or cost-per-acquisition (CPA) method.

From tactics like cookie stuffing and URL hijacking to IP spoofing and discount code abuse, affiliates have plenty of unsavory tactics up their sleeves.

Affiliate Fraud Statistics & Financial Impact

Affiliate fraud is estimated to cost advertisers as much as $3.4 billion in annual losses. It’s unfortunate, but not too surprising when you consider that one in six clicks are suspected to be fraudulent.

To add insult to injury, the downstream consequences of affiliate fraud impact far more than your marketing budget alone. This type of fraud can lead to higher operating costs across the board, compromise your data security, or even lead to chargebacks down the road.

Affiliate Fraud Examples

Affiliate fraud isn’t monolithic. Every referral channel, stage in your conversion funnel, and product in your inventory can be exploited by fraudsters who are out to game the system.

Hearing from merchants and agencies who are familiar with affiliate fraud and how it plays out in real life can help you sharpen your instincts against this insidious scam.

How to Identify Affiliate Fraud Attacks

Closely scrutinizing your affiliates and their performance can help you identify potentially fraudulent partners. An affiliate who sends you a lot of traffic that results in very few conversions, for instance, could be engaging in click fraud. Ditto for an affiliate who refers traffic from suspicious IP addresses or geographies.

Interestingly, a similar story can be told for an affiliate whose traffic results in sky-high conversion rates. Instead of high-quality traffic, this affiliate could simply be purchasing your products themselves then disputing them later.

How to Prevent Affiliate Fraud

Keeping fraudulent affiliate partners at bay requires you to introduce some intentional friction into the affiliate onboarding process. In practice, this means eschewing the low-touch, fully-automated onboarding process that is standard within the industry, and instead subjecting affiliates to manual approval.

A careful vetting process, though, is just the first step. Implementing clear terms and conditions for affiliates, deploying affiliate monitoring software, and subjecting partners to regular performance audits can all help you catch bad actors as they strike.

How does affiliate fraud work?

Affiliate fraud typically falls into one of two categories: either the fraudster employs deceptive tactics to persuade a cardholder to make a purchase, or uses stolen information to submit fraudulent transactions. In either case, the goal is to trick the advertiser into paying out commissions that the “affiliate” did not actually earn.

What does it mean if someone is an affiliate?

How do you prove commission fraud?

Proving commission fraud requires documenting suspicious patterns in traffic data, conversion rates, or lead quality that deviate significantly from normal metrics. Evidence can include unusually high click-to-conversion ratios, traffic from known bot networks, duplicate or fake customer information, or inconsistencies in referral source data that indicate artificial manipulation.
