Prevent fake install data corrupting your Meta conversion campaign audiences
Fake install attribution in your Meta account contaminates the Custom Audiences that power your conversion campaigns. When fraudulent install profiles are used as conversion audience seeds or lookalike sources, your conversion campaigns reach audiences modelled on fake users, raising your true cost per acquisition while your reported ROAS stays artificially stable. Tapper cleans your install attribution data to protect conversion campaign audience quality.

Fake install attribution corrupts the audience seeds that drive your Meta conversion campaigns
Advertisers who run both Meta app install campaigns and conversion campaigns often use their app installer audience as a high-intent seed for conversion campaign targeting. When fake installs inflate your installer Custom Audience with fraudulent device profiles, every conversion campaign that uses that audience, whether for direct retargeting or as a lookalike seed, is inheriting contaminated data. Your conversion campaigns reach audiences modelled on fraudulent installer profiles rather than genuine high-intent users, and your CPA rises without any obvious explanation in campaign performance data.
The contamination cascades through your Meta account's audience infrastructure. A lookalike audience built from a fake-install-contaminated Custom Audience directs your conversion campaign toward users who share characteristics with fraudulent install sources. Your creative testing results become unreliable because the audience receiving your ads does not reflect your genuine potential customers. Bid optimisation targets established against this audience composition will not transfer accurately when you attempt to scale your conversion campaigns toward genuinely high-value audiences.
How Tapper stops fake installs on Meta conversion campaigns
Three steps from connection to clean campaign data, no engineering required.
01
Audit and clean your app install attribution data
Tapper analyses your Meta install attribution records for fraud indicators including timing anomalies, post-install behaviour absence, and device cluster patterns, identifying fake install profiles before they enter your Custom Audiences.
02
Exclude fraudulent install profiles from conversion campaign audiences
Fake install profiles are identified and excluded from the Custom Audiences used to target and seed your conversion campaigns, ensuring audience models are built on genuine user data.
03
Improve conversion campaign targeting precision and ROAS accuracy
With fake install contamination removed from your audience infrastructure, your conversion campaigns reach genuine high-intent users, and your ROAS reflects real revenue generation rather than figures distorted by audience quality degradation.

“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.”

“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 Meta Ads conversion campaigns.
The contamination occurs through your Meta account's shared audience infrastructure. If you have ever used your app installer Custom Audience as a targeting source or lookalike seed for conversion campaigns, fake install profiles in that audience will have influenced the delivery of those conversion campaigns. The effect persists through saved and generated audiences until the contaminated source data is identified and cleaned.
Not directly. Meta Ads Manager does not provide install-level fraud classification or cross-campaign contamination reporting. The most reliable indicators are persistent underperformance of conversion campaigns that use installer-derived audiences compared to campaigns using other audience sources, combined with a gap between install-to-engagement rates that suggests a portion of your installer base was never real users. Tapper quantifies this by providing fraud-adjusted install attribution data.
For advertisers using an MMP like AppsFlyer or Adjust, Tapper can integrate at the MMP level for the most comprehensive fake install detection. For advertisers relying on Meta's native install reporting, Tapper can analyse the available attribution signals to identify fraud indicators. Both integration approaches provide meaningful protection for your conversion campaign audience quality.
