Fake install fraud on open exchange programmatic campaigns
App install campaigns buying open exchange inventory are targeted by fraudulent publishers who route bot and device farm traffic through install tracking links to generate fake CPI events.

Open exchange app install campaigns carry the highest fake install risk in programmatic
When app advertisers buy open exchange inventory for mobile user acquisition, the minimal publisher vetting of the open exchange creates ideal conditions for fake install fraud. Fraudulent publishers within the bid stream can route bot or device farm traffic through your app install tracking links, generating simulated install events that register with your mobile measurement partner as legitimate CPI attributions. Because the open exchange encompasses thousands of publisher domains with no individual relationship between the advertiser and publisher, isolating the fraudulent sources is extremely difficult without cross-referencing DSP impression data with MMP attribution data.
The financial model of fake install fraud on the open exchange is straightforward: fraudulent publishers earn CPI payouts for installs that cost them almost nothing to generate, while your UA budget is consumed by events that deliver no real users. Your MMP reports rising install volumes. Your cost per install appears within target. But your post-install engagement data tells a different story: zero retention, no in-app activity, and user cohorts that churn immediately because they were never real. Standard brand safety tools have no visibility into the attribution chain and cannot detect this fraud at any level.
How Tapper stops fake installs on Display open exchange
Three steps from connection to clean campaign data, no engineering required.
01
Connect your DSP and MMP to Tapper
Tapper integrates with your demand-side platform and mobile measurement partner, monitoring the full attribution chain from open exchange impression through to install event and post-install behaviour.
02
Fake install patterns identified across the attribution chain
Click-to-install timing analysis, device signal verification, and post-install behavioural scoring identify fraudulent installs attributed to open exchange inventory, including sophisticated operations that simulate early in-app events.
03
Fraudulent inventory excluded from future UA campaigns
Open exchange publishers linked to fake install activity are suppressed from your programmatic buying, with install attribution data corrected in your MMP reporting to reflect genuine CPI performance.

“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 Display & Programmatic open exchange.
Open exchange inventory is available to any publisher who joins an ad exchange, with minimal vetting of traffic quality or publisher legitimacy. Fraudulent publishers can enter the bid stream, serve your app install ad to bot or device farm traffic, and route simulated install events through your tracking links without any direct relationship with you as the advertiser. PMP deals require publisher vetting that significantly reduces this risk.
Tapper cross-references DSP impression data with MMP attribution data at the individual event level, analysing click-to-install timing distributions, device signal consistency, and post-install behavioural patterns. Real users acquired through display campaigns exhibit natural app engagement that differs fundamentally from device farm or bot-simulated installs, even when those installs are engineered to pass basic MMP fraud rules.
Not necessarily. Open exchange can deliver real user acquisition at scale and competitive CPIs when fraudulent inventory sources are identified and suppressed. Tapper enables you to run open exchange app install campaigns with continuous fraud monitoring, building a suppression list of high-fraud inventory sources and improving your clean CPI over time rather than abandoning the channel entirely.
