Ad Fraud in Mobile: What It Looks Like and How to Keep It Out of Your Budget

The fraud that costs you most

Three categories account for the majority of mobile UA fraud:

• Click injection and click spam — fraudulent apps fire fake clicks just before an organic install completes, stealing credit (and your payout) for users you never paid to reach.
• SDK spoofing — fake installs and events generated on servers, mimicking real devices closely enough to pass naive validation.
• Bot and emulator traffic — device farms that install, open and even 'engage' with apps to mimic real users through early funnel events.

Why install counts don't protect you

Fraudsters optimize for the metric you pay on. If you buy installs, you get install-shaped fraud. The reliable defense is measuring what fraud can't easily fake: retention curves, in-app purchase behavior, session depth — the downstream signals of a real human.

This is why post-install event data matters so much. A source delivering cheap installs with day-7 retention near zero isn't a bargain; it's a leak.

The defense stack

Effective protection is layered: pre-bid filtering that refuses to buy suspicious inventory in the first place, MMP-level fraud validation that catches attribution manipulation, and post-install analysis that flags sources whose users don't behave like humans.

Just as important is supply quality at the source. Buying through premium exchanges with direct publisher relationships removes most of the long-tail inventory where fraud concentrates.

Our approach

Adora DSP filters fraud pre-bid, validates through your MMP, and reports source-level quality transparently — so questionable traffic is excluded before it costs you, not explained after. Combined with 24/7 human oversight of every account, anomalies get caught by people who know your baseline, not just by thresholds.
