How CPA Fraud Happens
CPA campaigns are manipulated by fraudsters through fake results such as bots, fake accounts, and some of the most advanced tricks like SDK spoofing. In particular, their ambition is to manipulate the systems in order to recognize such actions as conversion, including the fake report on payout provided without the value.
For example:
- A bot simulates thousands of app installs.
- Fake users sign up for newsletters and do not perform any subsequent interactions.
- Malicious actors trick tracking systems to record phantom or ghost transactions.
Types of CPA Fraud
1. Click Fraud
Click fraud is when real or paid traffic is faked through the help of bots or click farms.
- How it works: Fraudsters often replicate users’ actions manually by clicking on the ads and hence increase interaction ratios.
- Impact: Advertisers invest in cost-per-click advertising that generates traffic but fails to result in sizable conversions.
2. Fake Sign-Ups or Installs
Fake accounts or app installs are generated using automated tools or emulators.
- How it works: There are fake users during registration or application downloads but they don’t use it in real life.
- Impact: Campaigns receive fake conversions which makes wastage of money spent on advertising.
3. Cookie Stuffing
Fraudsters inject cookies into the user’s browser without their knowledge to pass off unrelated conversions for their own.
- How it works: Every time users shop and engage in genuine transactions, the cookies of fraudsters mimic the action to be known to the fraudsters.
- Impact: The money reaches the wrong people, and they never had to do anything to bring this conversion.
4. SDK Spoofing
This is quite a complex form of fraud that resembles normal operations of the app and causes the analytics system to register its actions.
- How it works: Fraudsters feed the tracking systems with false install and event signals.
- Impact: Inflated metrics distort campaign performance analysis.
5. Domain Spoofing and Typosquatting
Scam websites imitate other genuine websites designed to capture leads or with the primary goal of deceiving users.
- How it works: Minor domain variations entrap people who mistakenly type the wrong proper URL address.
- Impact: Users are manipulated and the advertisers are charged unreasonable fees by the scammers.

Detecting CPA Fraud
1. Analyze Traffic Behavior
Try to find high traffic and low sales, or ratios where the clicks are significantly higher than the total number of sales made.
2. Monitor IP Addresses
Check for the instances when several conversions occurred from the same IP, this means that the traffic is bots.
3. Check Conversion Times
When conversion comes within a short time, say within seconds after clicking an advert then they are automated.
4. Track Post Conversion Engagement
Fraud brings low-interaction level where people uninstall the app, or use it once and then exit the session.
Preventing CPA Fraud
