Stop fake installs on open exchange programmatic campaigns
App install campaigns buying open exchange inventory are targeted by invalid 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 installs. Invalid 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 invalid sources is extremely difficult without cross-referencing DSP impression data with MMP attribution data.
The financial model of fake installs on the open exchange is straightforward: invalid 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 these installs 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 behavior.
02
Fake install patterns identified across the attribution chain
Click-to-install timing analysis, device signal verification, and post-install behavioral scoring identify invalid installs attributed to open exchange inventory, including sophisticated operations that simulate early in-app events.
03
Invalid 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.

“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.”

Frequently asked questions
Open exchange inventory is available to any publisher who joins an ad exchange, with minimal vetting of traffic quality or publisher legitimacy. Invalid 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, analyzing click-to-install timing distributions, device signal consistency, and post-install behavioral 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 validation rules.
Not necessarily. Open exchange can deliver real user acquisition at scale and competitive CPIs when invalid inventory sources are identified and suppressed. Tapper enables you to run open exchange app install campaigns with continuous invalid traffic monitoring, building a suppression list of high-IVT inventory sources and improving your clean CPI over time rather than abandoning the channel entirely.
