Stop invalid traffic on mobile app install campaigns
Invalid clicks, fake installs, and SDK spoofing drain your CPI budget before real users ever see your app. Tapper detects and blocks invalid traffic across all UA networks so every install you pay for is genuine.

App install campaigns attract more invalid traffic than almost any other mobile ad format
App install campaigns operate on a cost-per-install model, which means every invalid install directly extracts money from your UA budget. Bad actors target CPI campaigns because the payout is clear, the signal is easy to fake at the device level, and most MMPs lack the behavioural analysis required to distinguish real installs from spoofed ones. Industry estimates place invalid installs at 28% of all mobile installs globally, meaning that on an unprotected campaign, nearly one in three installs you pay for may never involve a real user.
The damage extends beyond direct budget theft. When fake installs enter your attribution data, every downstream metric is distorted. Your CPIs look acceptable because the raw install count is inflated. Your LTV models are built on cohorts that include users who do not exist. Your bidding algorithms on Google UAC, Meta, Apple Search Ads, and other networks learn from this polluted signal, and optimise toward the sources generating the most invalid installs rather than the most genuine users. The longer invalid installs accumulate in your data, the more difficult it becomes to trust any performance metric.
Standard MMP invalid traffic protection relies primarily on CTIT thresholds, device ID blacklists, and known bad actor databases. These rules catch unsophisticated schemes but miss the techniques most commonly used at scale today. SDK spoofing, which accounts for 40% of invalid mobile traffic, produces device signals that are indistinguishable from real installs at the level MMPs inspect. Click injection and click stuffing manipulate the attribution window before CTIT rules trigger. Device farms use genuine hardware that passes device ID checks. Protecting app install campaigns requires a layer of analysis that goes beyond what any MMP provides natively.
How Tapper protects your app install on Mobile
Three steps from connection to clean campaign data, no engineering required.
01
Connect your MMP and UA campaign accounts
Tapper integrates directly with AppsFlyer, Adjust, Kochava, Singular, Branch, and your ad networks including Google UAC, Meta, Apple Search Ads, and others. Every click and install event is monitored from the moment integration is live.
02
Invalid traffic signals detected across the full install funnel
SDK spoofing signatures, click injection patterns, device farm clusters, CTIT anomalies, and velocity signals are all analysed simultaneously. Tapper combines device-level and behavioural analysis to catch invalid installs that pass standard MMP checks.
03
Only genuine installs reach your attribution data
Invalid installs and clicks are excluded before they enter your MMP. Your CPI figures reflect real users, your bidding algorithms learn from clean data, and your LTV models are built on cohorts that actually exist.

40%
higher conversion rate
“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimises 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.”

lower CPA
Up to $50K
saved per year
“We've been using Tapper for over a year now, and it has become a core part of how we run paid media. Invalid traffic was always something we knew existed but couldn't really act on. Tapper changed that. We're now saving up to $50K per year, and on PureSquare specifically, we saw around a 20% decrease in CPA. Based on these results, we decided to roll it out across other ventures under Disrupt as well.”

Frequently asked questions
Everything you need to know about protecting your app install on Mobile App.
Tapper provides install-level invalid traffic classification with a breakdown by campaign, network, creative, and traffic type. Most UA managers without active invalid traffic protection find that 20 to 40% of installs on some networks are invalid. After connecting Tapper to your MMP, you can see the exact proportion of invalid installs within the first 24 hours of monitoring.
MMPs inspect device-level signals to verify installs. Sophisticated techniques, particularly SDK spoofing, replicate those signals accurately enough to pass MMP checks. Tapper analyses the behavioural pattern of the full session, including timing variation, event sequencing, and session depth, which bad actors cannot replicate with the same fidelity as device signals.
Yes. Tapper integrates with all major UA networks and monitors click and install traffic across all of them from a single dashboard. You get unified invalid traffic visibility regardless of how many networks your campaigns run on.
Blocking invalid traffic does not affect legitimate campaign delivery. Your ads continue to run and your ad networks continue to serve impressions to real users. The only change is that invalid clicks and fake installs are excluded from your attribution data and your CPI payout model, so your reported metrics reflect genuine performance.
Your install count will fall to reflect only real users. Your CPI may initially appear higher because the denominator is smaller. But your downstream metrics, retention, revenue, ROAS, will improve because they are no longer diluted by users who do not exist. The installs you were counting before were not generating revenue; the ones Tapper confirms are.
Click injection is primarily an Android issue because it exploits the Play Store install broadcast. On iOS, the equivalent risk is click stuffing and CTIT manipulation, where bad actors flood tracking links with clicks timed to coincide with organic installs. Tapper monitors both Android and iOS campaigns and applies the relevant detection models for each platform.
Other campaign types on Mobile App
Each campaign type has its own invalid traffic patterns. Tapper covers them all on Mobile.
