Stop click fraud in your affiliate CPC campaigns
Affiliate CPC campaigns pay publishers for every click regardless of whether that click leads to a genuine user. Fraudulent publishers inflate click volumes through bots, click farms, and automated scripts to maximise their CPC earnings at your expense. Tapper identifies and filters fraudulent clicks before they reach your billing calculations.

CPC affiliate fraud inflates your click costs without delivering real traffic
Cost per click affiliate programmes create a direct financial incentive for publishers to inflate click volumes because every click generates revenue regardless of user intent or quality. Fraudulent publishers exploit this model by deploying bot traffic, click farm operations, and automated scripts that generate clicks at high velocity without any genuine user behind them. Your CPC budget is consumed, your click volume reports look healthy, but your downstream conversion rates collapse because the traffic arriving at your landing pages has no real purchase intent.
The cost of CPC fraud extends beyond the direct spend on invalid clicks. Inflated click data corrupts the signals you use to evaluate publisher quality, set CPC bid rates, and allocate budget across your affiliate programme. Publishers generating fraudulent high-volume clicks appear to be strong performers in your network dashboard, attracting higher commission tiers and larger budget allocations. Legitimate publishers who drive genuine, lower-volume but higher-intent traffic are ranked below their fraudulent competitors and receive a smaller share of your programme budget.
Tapper analyses every click entering your affiliate CPC programme against a comprehensive set of fraud signals, including IP reputation, device fingerprinting, session behaviour, click velocity patterns, and geographic clustering. Fraudulent clicks are identified and excluded from billing calculations before they inflate your costs, and publisher-level reporting gives you the visibility to identify and remove bad actors from your programme.
How Tapper protects your cpc campaigns on Affiliate
Three steps from connection to clean campaign data, no engineering required.
01
Integrate Tapper with your affiliate CPC tracking
Tapper connects to your affiliate network or in-house CPC tracking platform and begins analysing every incoming click for fraud signals, monitoring publisher traffic in real time across all your CPC campaigns.
02
Invalid clicks detected through multi-signal analysis
Each click is scored against IP reputation data, device fingerprints, session behaviour patterns, click velocity, and geographic clustering signals to identify bot traffic, click farm activity, and automated scripts generating fraudulent CPC volume.
03
Fraudulent clicks excluded from billing and publisher rankings
Invalid clicks are removed from your billing calculations before CPC costs are totalled, and publisher fraud scores are updated in real time so your programme management reflects genuine traffic quality rather than inflated click volume.

“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

“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 cpc campaigns on Affiliate.
In search advertising, click fraud is typically driven by competitors or malicious third parties targeting your ads. In affiliate CPC programmes, the primary fraud source is your own publisher base, specifically publishers who inflate click volumes to increase their CPC earnings. This makes affiliate CPC fraud harder to detect through standard ad platform tools because the fraud originates from within your approved partner network rather than from external attackers.
Yes. Tapper's fraud detection covers residential proxy networks, which are increasingly used by click farm operators to make their traffic appear to originate from genuine home broadband connections. Detection relies on behavioural analysis and session signals rather than IP reputation alone, so click farm patterns are identified even when the IP addresses themselves appear legitimate.
Tapper provides a per-publisher fraud dashboard showing invalid click rates, fraud signal breakdowns, and supporting evidence for each flagged publisher. You can see which publishers are generating bot traffic, click farm activity, or VPN-masked clicks, with enough detail to support account suspension decisions and commission disputes through your affiliate network.
No. Tapper's fraud analysis runs in the background and does not add meaningful latency to legitimate click journeys. Genuine user clicks are processed and passed through normally. Only clicks identified as fraudulent are flagged and excluded from billing, with no impact on the experience of real users engaging with your affiliate content.
Budget recovered through fraudulent click exclusion remains in your programme and can be reallocated to high-performing legitimate publishers. Over time, with fraud removed from your click data, the signals you use to set CPC rates, rank publishers, and allocate programme budget become significantly more accurate, improving your overall return on affiliate spend.
