Invalid traffic removal for mobile apps
SDK spoofing, fake installs, and fake in-app events are corrupting your mobile attribution data and draining your UA budget. Tapper detects invalid mobile traffic, protecting your app campaigns across every network and MMP.

Invalid mobile traffic is the most technically sophisticated category of all
Invalid mobile traffic has evolved into the most technically complex category of all, precisely because mobile attribution relies on signals that are difficult to verify quickly. The mobile ecosystem's fragmentation: dozens of ad networks, multiple measurement partners, device ID systems, and operating system variations, creates countless seams through which invalid traffic can operate undetected. Invalid mobile traffic cost advertisers an estimated $10 billion globally in 2023, and that figure continues to rise.
SDK spoofing is the most damaging form of invalid mobile traffic. Bad actors reverse-engineer the SDKs used by mobile measurement partners and simulate the device-level signals that a real install and app launch would generate, without any real device or real user being involved. Your MMP receives what appears to be a valid install event, complete with device ID, location data, and app session data. The install is counted, the CPI is paid, and no real user ever downloaded your app.
Click flooding, device farms, and fake in-app events complete the picture. Click flooding buries legitimate click paths under thousands of invalid clicks to claim attribution credit. Device farms use warehouses of real physical devices to generate installs that defeat device-signal-based detection. Fake in-app events simulate post-install actions: tutorial completions, purchases, level completions, to pass filters that only check install quality, unlocking higher CPA payouts. Tapper analyzes the full session lifecycle to detect invalid activity at every stage.
How Tapper protects your Mobile campaigns
Three steps from connection to clean data, no engineering required.
01
Connect your MMP and ad networks
Tapper integrates with your mobile measurement partner (AppsFlyer, Adjust, Kochava, Singular, and Branch) and your ad network accounts to monitor the full attribution chain.
02
Invalid traffic detected across the full install funnel
From click to install to in-app event, Tapper analyzes every signal for SDK spoofing patterns, click flooding, device farm signatures, and fake in-app events.
03
Protect your UA budget and LTV data
Invalid installs are identified and excluded from your campaign data. Your cost-per-install reflects real users, and your LTV models are built on genuine user behavior.

“Tapper played a key role in improving the efficiency of Du's performance marketing activity by addressing traffic quality issues within campaigns. Following implementation, Du achieved a 13% reduction in CPA and an 8.6% increase in order rate, demonstrating a clear improvement in conversion quality and overall campaign effectiveness.”

“We uncovered low-quality traffic that wasn't visible inside the platforms. Removing it delivered a 14% uplift in conversions and an 11.4% reduction in CPA, a meaningful efficiency gain for INFINITI's 2026 growth plans.”

“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimizes against cleaner signals and the efficiency comes through quickly. For AMA Nissan, that was a 40% lift in conversion rate and a lower CPA on Google, with nothing else in the setup changing. That is the kind of result we want to offer clients as a matter of course.”

Calculate your lossesFrequently asked questions
SDK spoofing is when bad actors reverse-engineer your mobile measurement partner's SDK and simulate the exact device signals that a real install would generate, without any real device or user being involved. Because the signals look identical to legitimate installs, standard detection that relies on device signals alone cannot detect it. Tapper uses behavioral analysis of the full session lifecycle to identify spoofed installs.
Click flooding generates thousands of invalid clicks against your tracking links in a short time window. When a real user later installs your app organically or through another channel, there is a high statistical probability that one of the invalid clicks appears as the last touch before install and claims the cost-per-install payout. Your genuine organic installs and paid channel performance are both understated as a result.
Yes. Tapper integrates directly with major mobile measurement partners including AppsFlyer, Adjust, Kochava, Singular, and Branch. We sit alongside your MMP rather than replacing it, adding an additional invalid traffic detection layer that analyzes signals your MMP may miss.
Device farms are physical locations, sometimes entire warehouses, containing hundreds or thousands of real mobile devices. Operators use these devices to generate installs, engage in post-install events, and produce the kind of real-device signals that defeat software-based detection. Tapper identifies device farm activity through cluster analysis, detecting when multiple device IDs share identical network environments, usage patterns, or geographic locations.
Tapper monitors the full session lifecycle from install through in-app events. Invalid sessions that simulate post-install activity: in-app purchases, level completions, tutorial finishes, are identified through behavioral analysis. They lack the natural variation, timing irregularities, and interaction patterns that real user sessions produce.
Yes. Mobile retargeting campaigns are vulnerable to invalid traffic through the same mechanisms as acquisition campaigns: click flooding, fake re-engagement events, and fake in-app activity. Tapper monitors retargeting traffic with the same analysis depth as acquisition, ensuring your reengagement spend reaches real lapsed users rather than bad actors.
