Fraud Prevention in Mobile Advertising: A Publisher and Advertiser Guide

Common Types of Mobile Ad Fraud

1. Click Injection

Fraudsters inject fake clicks just before legitimate installs to claim attribution credit, diverting revenue from genuine publishers.

2. SDK Spoofing

Fake install events are sent directly to attribution platforms without any actual installs.

3. Click Farms

Networks of humans or bots generate fraudulent engagement and installs to manipulate campaign metrics.

4. Device Farms

Clusters of physical devices simulate legitimate user behavior to falsely inflate traffic.

5. Install Hijacking

Legitimate installs are intercepted and redirected, giving fraudsters credit for conversions they didn’t earn.
