Frequently asked questions

What is AppsFlyer’s fraud protection?

AppsFlyer’s fraud protection helps you detect and block ad fraud across every stage of the user journey, from click to install to in-app event. It uses AI, machine learning, behavioral modeling, and pattern analysis to flag suspicious activity in real time and after attribution. You can catch fraud even after an install is recorded, ensuring your results reflect real user engagement. This gives your team the clean data and confidence needed to optimize performance and invest budget more effectively.

Who is AppsFlyer’s fraud protection for?

UA and growth marketers, analytics teams, and marketing executives who want to ensure accurate measurement, optimize campaign performance, and scale with cleaner, more reliable data. It also supports leaders looking to understand fraud’s business impact and protect budget strategies as they grow.

What types of mobile ad fraud does AppsFlyer detect?

AppsFlyer detects and blocks install hijacking, click flooding, attribution spoofing, bot traffic, device farms, fake in-app events, and CPA manipulation. Its detection models evolve continuously to identify new fraud patterns across channels, with AI and behavioral analysis enhancing speed and accuracy.

Can I identify fraud after install?

Yes. AppsFlyer detects post-install fraud by identifying suspicious patterns after attribution. While you can’t block fraud retroactively, you can export post-attribution findings to reconcile with media partners and prevent repeat abuse, helping protect future budgets and maintain data integrity.

How can I protect CPA campaigns from fraud?

AppsFlyer detects fake post-install events that fraudsters use to appear as valuable users in CPA campaigns. A combination of rule-based detection, behavioral analysis, and AI helps identify and filter out invalid conversions, so you can protect your ROI and focus budget on real user engagement.
