Stop affiliate fraud in your CPA campaigns
Fraudulent publishers generate fake conversions that trigger CPA payouts without acquiring a single genuine customer. Your cost per acquisition rises, your conversion data becomes unreliable, and your programme pays out real commission on traffic that never converted legitimately. Tapper detects and blocks fraudulent CPA conversions before they reach your payout calculations.

CPA affiliate fraud inflates your costs and corrupts your conversion data
Cost per acquisition programmes are the highest-value target for affiliate fraud operators because the payout is tied directly to a conversion event. Fraudulent publishers use bot scripts, device farms, and click stuffing techniques to simulate the exact actions your CPA model requires, whether that is a purchase, a form submission, a free trial sign-up, or an account registration. Your affiliate network records a valid conversion, your attribution platform credits the publisher, and a commission payout is triggered. No real customer exists on the other side of that transaction.
The downstream damage extends beyond the commission budget itself. Fraudulent CPA conversions corrupt the customer data your sales and retention teams rely on. Fake leads flood your pipeline with contacts that never respond. Fraudulent purchases generate chargebacks and inflate your refund rates. Fake registrations distort your cohort analysis and make your genuine acquisition costs invisible beneath the noise. Every business decision built on CPA conversion data becomes less reliable when fraud is not removed from the signal.
Tapper analyses the full conversion funnel, from click origin through to the conversion event itself, identifying the behavioural and technical inconsistencies that distinguish fraudulent CPA conversions from genuine ones. Publisher-level fraud scoring gives your programme management team the visibility they need to act on fraud before it escalates, and pre-payout fraud rejection ensures your commission budget flows only to partners who drive real customers.
How Tapper protects your cpa campaigns on Affiliate
Three steps from connection to clean campaign data, no engineering required.
01
Connect your affiliate tracking and CPA attribution
Tapper integrates with your affiliate network or in-house tracking platform and begins monitoring every click and conversion event in your CPA programme, including the full attribution chain from click source through to the conversion action.
02
Fraudulent CPA conversions detected through behavioural analysis
Each conversion is evaluated against a set of behavioural and technical signals, including session duration, device fingerprint consistency, form completion patterns, click-to-conversion timing, and IP reputation, to identify conversions that do not reflect genuine customer behaviour.
03
Fraudulent conversions excluded before commission payouts
Conversions flagged as fraudulent are excluded from your programme's payout calculations before commission is issued, protecting your CPA budget and ensuring your conversion data reflects only genuine customer acquisitions.

“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 you need to know about protecting your cpa campaigns on Affiliate.
Fraudulent publishers use a range of techniques depending on the conversion type. For form submissions and lead generation, bot scripts and human click farms complete forms with fabricated contact details. For purchase-based CPA models, fraud operators exploit free trial mechanisms, use stolen card data, or complete checkout flows that result in immediate chargebacks. For app installs and registrations, device farms and emulator environments generate the install and registration events your attribution system records as valid conversions. Tapper analyses the behavioural signals of each conversion to identify the inconsistencies these methods cannot replicate.
Yes. Tapper integrates with major affiliate networks including Impact, CJ Affiliate, Rakuten, ShareASale, and Awin, as well as custom in-house tracking setups. For CPA programmes using a mobile measurement partner, Tapper also integrates with AppsFlyer, Adjust, Kochava, Singular, and Branch. Our team can advise on the best integration approach for your specific programme structure.
Fraudulent CPA conversions distort the performance metrics you use to evaluate and rank publishers. Fraud-inflated conversion volumes from dishonest publishers make them appear to outperform legitimate partners, skewing your tier decisions, commission rate negotiations, and budget allocation. Removing fraud from your programme data gives every legitimate publisher a fair and accurate representation of their contribution.
Yes. Many fraud operators pass initial publisher approval using legitimate-looking websites and early low-volume activity before scaling their fraudulent conversion generation. Tapper monitors publisher behaviour continuously throughout their time in your programme, not just at the point of approval, so fraud that emerges after onboarding is detected and flagged in real time.
Each flagged conversion includes a detailed fraud report covering the specific signals that triggered the fraud decision: IP reputation, device fingerprint data, session behaviour scores, click-to-conversion timing analysis, and comparison against known fraud patterns. This evidence supports commission clawback requests to your affiliate network and can be used to justify publisher suspension or removal from your programme.
