Fake install fraud on affiliate CPA campaigns
While fake installs are primarily a CPI threat, CPA campaigns with app-engagement conversion events are targeted by publishers who inject fraudulent install-triggered actions to claim commission.

CPA campaigns with app-based conversion events face publisher-injected fake install fraud
Fake installs are most commonly associated with CPI affiliate programmes, but CPA campaigns that include app-based conversion events, such as completed app registrations, first in-app purchases, or tutorial completions as the commission trigger, are also targeted by publishers who generate fraudulent install events to claim CPA commission. The mechanism is essentially the same as CPI fake install fraud, but the target is a higher-value conversion event rather than the install itself. Publishers generate simulated installs and then simulate the specific in-app action that triggers your CPA commission.
The challenge of detecting fake install-linked fraud on CPA programmes is that the fraudulent publisher must simulate not just an install but the specific downstream conversion event that your programme pays commission for. This requires more sophisticated fraud infrastructure than basic install generation. However, the pattern of post-install behaviour from these fraudulent sessions is still distinctive: the in-app actions happen at unnaturally uniform timing, lack the exploratory behaviour of genuine new users, and are followed by immediate session termination rather than the ongoing engagement patterns of real customers.

“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 Affiliate cpa campaigns.
On a CPI programme, a fake install directly triggers commission. On a CPA programme, the fraudulent publisher must additionally simulate the specific downstream conversion event, such as an account registration, a first purchase, or a tutorial completion, to claim the higher CPA commission. This requires more sophisticated fraud operations but also yields proportionally higher payouts per fraudulent event. Tapper analyses the full conversion chain, from install through to the specific CPA event, to detect fraud at every step.
CPA programmes that pay for post-install events are targeted by more sophisticated fraud operations than basic CPI programmes, because the payout is typically higher and the fraud requires more capable simulation infrastructure. However, the requirement to simulate specific post-install behaviour also creates more detectable patterns: the timing, sequencing, and quality of simulated in-app events differs from genuine user engagement in ways that Tapper's behavioural analysis can identify.
Yes. Tapper integrates with AppsFlyer, Adjust, Kochava, Singular, and Branch, operating alongside your MMP rather than replacing it. Tapper adds a behavioural analysis layer that examines post-install session quality and in-app event sequencing, identifying fake install-linked fraud that MMP detection rules are not designed to catch.
