Affiliate fraud protection for e-commerce
E-commerce affiliate programmes are among the most targeted in the industry. Fake orders, click stuffing, and coupon abuse drain your commission budget and corrupt the conversion data your programme depends on.

E-commerce affiliate fraud turns your commission model against you
E-commerce affiliate programmes are built on a simple promise: pay a commission only when a publisher drives a genuine sale. Fraud operations subvert this model by generating fake orders, stuffing affiliate cookies onto shoppers who were already converting, and exploiting coupon and cashback publishers to claim commission on orders that would have happened without any affiliate involvement. Your cost of sale rises, your margin calculations are wrong, and your best-performing legitimate publishers are crowded out by fraudulent ones.
Cart abandonment patterns, high return rates, and churn after the first purchase are the downstream symptoms of affiliate fraud that e-commerce teams often attribute to product or UX issues. When fake or low-quality conversions are systematically attributed to affiliate traffic, your cohort data appears to show that affiliate customers have poor lifetime value, which undermines investment in the channel. The real problem is that fraudulent conversions are diluting the data. Genuine affiliate customers are often among the highest-LTV segments when measured on clean data.
Coupon and cashback fraud is a category of its own. Publishers operating cashback and voucher sites sometimes apply their affiliate cookie to purchases where no coupon was used, claiming last-click commission on transactions driven entirely by other channels or direct intent. Tapper analyses the full attribution path of every e-commerce conversion to identify last-click abuse, cookie stuffing, and fake order patterns before commission is calculated and paid out.

“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.”

“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.”

“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 e-commerce ad spend on Affiliate.
Cookie stuffing places your affiliate tracking cookie on a shopper's browser without any genuine click from a publisher. When the shopper later completes a purchase through direct navigation or organic search, the stuffed cookie claims last-click credit and a commission is paid to a publisher that played no role in the sale. Your genuine affiliate publishers lose commission credit they earned, and your programme pays for traffic it did not receive.
Indicators of genuine affiliate performance include normal click-to-purchase ratios, session durations consistent with genuine product research, low return rates on attributed orders, and customer lifetime value in line with direct and organic channels. Tapper provides per-publisher fraud scoring alongside these quality signals, giving you a complete picture of which publishers are driving real commercial value.
Yes. Tapper integrates with major e-commerce platforms and affiliate networks, including Impact, CJ Affiliate, Rakuten, and ShareASale, as well as custom in-house tracking setups. The integration approach depends on your specific platform and tracking configuration, and our team can advise on the best method for your programme.
Yes. Tapper analyses every conversion type, whether a completed purchase, a lead form, an email registration, or a free trial sign-up. For CPL e-commerce conversions, Tapper evaluates the submission against device signals, session behaviour, and email quality indicators to identify fraudulent sign-ups before they are counted as valid leads.
Returns-pattern fraud involves generating real orders through affiliate tracking, collecting the commission payout, and then returning the goods after the commission window closes. Tapper monitors post-conversion order data and flags publishers whose attributed customers show high return rates, unusually short order-to-return intervals, or product-category patterns consistent with organised returns abuse.
