Fake installs on Google App campaigns
Fake installs are the defining fraud threat for Google App campaigns. Fraudulent actors generate install signals without real users, collecting CPI payouts while delivering zero retained users, zero in-app engagement, and zero revenue. Tapper validates every install against real device behaviour and MMP attribution signals, ensuring your UAC budget acquires real users.

Fake installs corrupt your UAC campaign data and drain budget on users who never existed
Fake installs on Google App campaigns are generated through device farms, emulators, and sophisticated attribution fraud techniques that produce install signals indistinguishable from genuine user acquisitions at the surface level. Your UAC campaign reports a successful install, your MMP records the conversion, and your CPI bidding data updates accordingly, but no real user ever downloaded or opened your app. Industry data estimates that 28% of mobile app installs globally are fraudulent, and paid App campaigns are a primary target because they directly generate CPI revenue for fraudsters.
The impact of fake installs extends beyond direct budget waste. When fake installs inflate your UAC conversion data, your campaign's apparent install rate improves, causing your target CPI bidding to sustain or increase spend toward the traffic sources generating fake installs. Your Day-1 and Day-7 retention rates fall as the fake installs that produce zero engagement pull down your cohort averages. Your LTV models incorporate users with zero activity, distorting the lifetime value projections you use to set CPI targets. Every downstream metric of your app acquisition strategy is corrupted by fake installs upstream.
How Tapper stops fake installs on Google app campaigns
Three steps from connection to clean campaign data, no engineering required.
01
Validate installs against real device interaction data
Tapper cross-references every install attributed to your App campaigns against independent device fingerprint data collected at the ad-serving stage. Installs that cannot be matched to a verified real device interaction from your App campaign ads are flagged as potentially fake and separated from your genuine install count.
02
Detect click injection and attribution fraud patterns
Tapper monitors click-to-install timing relationships across your UAC campaigns. Click injection attacks produce statistically impossible timing windows where install attributions occur faster than a genuine app download could complete. These patterns are automatically flagged, preventing fraudulent CPI claims from being counted.
03
Protect UAC bidding with verified install data
Validated fake installs are removed from the conversion data feeding your UAC bidding algorithm. This prevents fake installs from suppressing your apparent CPI and from training your campaign algorithm toward the traffic sources generating fraudulent conversions. Your CPI targets reflect the real cost of acquiring engaged users.

“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.”
Joseph Elbcherrawy
Client Leadership Director, Mindshare, a WPP Media Brand
“During our Tapper trial for INFINITI, 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.”
David Barnes
Data & Technology Lead, Omnicom Group
“With Tapper's protection we were able to identify and block invalid clicks in real time. The impact was immediate as our cost per acquisition dropped by 30% and ROAS improved significantly. More importantly, Tapper gives us the confidence that our campaigns are reaching genuine customers, which makes it truly invaluable.”
Dimitris Bakas
Senior Performance Marketing, Public Group
“We started using Tapper to get better visibility on where our clicks were coming from, and ended up cutting wasted spend by over 12%. The performance uplift was clear, and for the first time, we could trust the numbers we were seeing. It's a total game-changer for campaign integrity.”
Stuart Parkin
Director of Operations, Regit
“Tapper's blocking technology purifies our paid media traffic which roughly equates to a 36x return against its subscription costs. It's certainly one of the easiest-to-implement tools in our entire marketing stack.”
Reno Mindemann
Head of Growth, Kama Capital
“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 about fake installs on Google Ads app campaigns.
The clearest post-install indicators of fake installs are retention rates near zero at Day 1, high immediate uninstall rates, and cohorts with no in-app events beyond the install itself. In some cases, your MMP may flag suspiciously fast click-to-install windows or device IDs that appear across multiple installs. Tapper identifies fake installs at the pre-attribution stage through device validation and click pattern analysis, before they enter your UAC conversion data.
Google has basic invalid activity detection for App campaigns, but its effectiveness against sophisticated fake install operations is limited. Click farms using real devices, emulators that fully simulate device environments, and click injection attacks that operate within normal attribution windows routinely bypass Google's detection. Google's detection is reactive rather than proactive, issuing credits after fraud is confirmed rather than preventing installs from being counted in the first place.
If you are bidding on in-app events such as registrations or purchases, fake installs that produce no in-app events lower your apparent conversion rate from install to in-app event. This causes your UAC algorithm to increase bids to compensate for the lower post-install conversion rate, raising the effective cost of acquiring users who genuinely complete your target events. Tapper's fake install filtering improves the accuracy of your in-app event conversion rate data, stabilising your CPA bidding.
