Fake installs 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 invalid install-triggered actions to claim commission.

CPA campaigns with app-based conversion events face publisher-injected fake installs
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 invalid install events to claim CPA commission. The mechanism is essentially the same as CPI fake installs, 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 abuse on CPA programmes is that the bad actor must simulate not just an install but the specific downstream conversion event that your programme pays commission for. This requires more sophisticated infrastructure than basic install generation. However, the pattern of post-install behaviour from these invalid 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.
How Tapper stops fake installs on Affiliate cpa campaigns
Three steps from connection to clean campaign data, no engineering required.
01
Connect your CPA tracking and MMP to Tapper
Tapper integrates with your affiliate CPA tracking platform and mobile measurement partner, monitoring the full attribution chain from affiliate click through install to the specific in-app conversion event that triggers your CPA commission.
02
Publisher-injected fake install patterns detected at the conversion level
Click-to-install timing, device signal analysis, in-app event sequencing, and post-conversion behavioural scoring identify invalid publisher-generated installs targeting your CPA conversion events.
03
Fake install-linked CPA conversions excluded before commission payouts
Publishers generating invalid install-linked CPA conversions are flagged with evidence, and the invalid conversion events are excluded from commission calculations before payouts are issued.

40%
higher conversion rate
“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimises 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.”

20%
lower CPA
Up to $50K
saved per year
“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 bad actor 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 operations but also yields proportionally higher payouts per invalid event. Tapper analyses the full conversion chain, from install through to the specific CPA event, to detect invalid activity at every step.
CPA programmes that pay for post-install events are targeted by more sophisticated operations than basic CPI programmes, because the payout is typically higher and the scheme 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 abuse that MMP detection rules are not designed to catch.
