Is Competitor Click Fraud Wasting Your Budget? How Click Scanner Protects Campaigns

Advertising Budgets Under Fire: The Ad Fraud Landscape in Europe

In the era of rapid e-commerce growth and the increasing dominance of performance marketing, corporate advertising budgets have become an attractive target for fraudulent entities. It is estimated that approximately 51% of all internet traffic is generated by machines rather than real users. Advertising fraud (ad fraud) is a phenomenon where funds allocated for paid campaigns (CPC, CPL) are wasted by bots, click farms, or deliberate competitor activity.

For companies operating across European markets—from Poland and Germany to France—protecting the capital spent on customer acquisition is becoming a key element of survival strategy. This issue is compounded by the fact that advertising platforms, despite their declared security systems, often react with a delay or fail to detect more subtle forms of manipulation.

Key fact: According to independent analyses, including Denis Atlan's market analysis based on 200 B2B deployments, automation and anti-fraud protection systems show a median ROI of +159.8% within 24 months of implementation, with an average payback period of just 8 months.

Understanding where advertising budget leaks occur is the first step toward securing your revenue. Below, we present the most common threats faced by modern advertisers.

Main Threat Categories: How Are You Losing Your Budget?

• Bots and Automated Scripts (Non-Human Traffic): Some bots are intentionally deployed by fraudulent publishers and ad networks. Every click on your ad generates CPC commission revenue for them, regardless of whether the user had any purchase intent. At night, when CPC rates can be lower, bots can generate thousands of clicks—by morning, the daily budget is fully depleted, with zero conversions to show for it.
• Malicious Competitor Clicks (Sabotage): The motivation here is entirely different. It is not about earning commissions, but rather about intentionally exhausting a rival's advertising budget. Studies indicate that on average, up to 7 out of 10 companies click on their competitors' ads. Often, these are employees or hired contractors clicking manually from various devices and locations to avoid raising suspicion on ad platforms. The result? Your ads disappear from the network during peak shopping hours.
• Click Farms and GPT (Get Paid To) Sites: Alongside bots, there are organized human-based operations. Click farms are facilities where dozens of people click on ads simultaneously for compensation. Users of GPT sites receive small payouts for clicking on ad links. This traffic comes from real people on real devices, making detection by standard Google or Meta filters extremely difficult.
• Accidental Clicks (Fat Finger): Between 10% and 50% of mobile ad clicks can be completely unintentional. Publishers often deliberately place ads right next to navigation buttons (e.g., under the 'next page' button on news portals), forcing users to click accidentally. You pay the full CPC rate for traffic with an immediate 100% bounce rate.
• Phantom Clicks: Situations where advertising platforms report more clicks than actually arrived on the landing page. This discrepancy means incurring costs without any trace of a visit in your analytics systems.
• Cookie Stuffing and Attribution Theft: Fraudulent affiliate publishers load ads in hidden iframes on their websites, dropping cookies onto users' devices without their knowledge. When the user eventually makes a purchase, the affiliate commission goes to the fraudster, even though other channels (such as organic search or newsletters) actually drove the conversion.

Who Should Consider Implementing Anti-Fraud Protection?

To help you assess the scale of the problem within your organization, we have prepared a breakdown of key challenges faced by different business sectors.

How Click Scanner by TrafficWatchdog Solves This Problem

Click Scanner is an advanced tool designed to monitor and protect advertising budgets in CPC models. The system monitors every click arriving on your landing page and evaluates its quality in accordance with IAB (Interactive Advertising Bureau) standards.

At the Heart of the System: Virtual Device Fingerprinting

Unlike simple filters that rely solely on IP addresses (which are easy to change), Click Scanner utilizes advanced Device Fingerprinting. The system analyzes dozens of non-personal technical parameters of the browser and hardware (such as operating system, browser version, installed fonts, graphics card parameters, or canvas fingerprint).

This allows the system to group repeating devices regardless of whether the user changes their IP address, clears cookies, or uses a VPN/Proxy. This serves as a critical shield against sophisticated click farms and competitors operating from mobile devices.

Traffic Classification: FAKE vs WORTHLESS

The system evaluates traffic quality and divides incorrect interactions (INCORRECT) into two main categories:

• FAKE (Fraudulent Traffic): Clicks showing direct, hard evidence of non-human origin. This includes inconsistencies in the fingerprint, the use of known automation tools (e.g., Selenium, headless browsers), detected virtual machines, spoofed user-agent headers, or IP addresses associated with TOR nodes, public VPNs, and datacenters.
• WORTHLESS (Invaluable Traffic): Interactions where the primary issue is behavioral. The user shows no activity on the page, mouse movement or scrolling patterns are unnatural, and the duration of the visit is extremely short. While there may not be hard proof of a bot, the click carries no purchase intent and is useless from a business perspective.

Active Blocking Methods

TrafficWatchdog offers two parallel methods of blocking unwanted traffic, which can be used together or separately:

1. API Access to Google Ads (IP Blocking): Click Scanner automatically adds IP addresses identified as fraudulent to the excluded IP list in the client's campaigns. This process runs automatically thanks to a one-time manager authorization for the account clickscanner@trafficwatchdog.pl.
2. Remarketing Lists (Google Ads and Facebook/Instagram Ads): The system generates a dynamic list of identified fraudulent users (based on fingerprints and cookies), which is then excluded from ad delivery in the Ad Manager. This is the only effective method for the Meta ecosystem (Facebook/Instagram), which does not offer an external API for blocking IP addresses.

Key fact: According to the ESET and DAGMA report "Cyberportrait of Polish Business 2026", as many as 85% of companies fell victim to various types of cyber incidents last year. The lack of active protection and monitoring of advertising campaigns exposes enterprises to direct financial losses, which are extremely difficult to prove to platform providers without proper analytical tools.

European Perspective and Regulatory Challenges

Running marketing campaigns across borders (e.g., in Germany, France, or the UK) requires compliance with strict legal standards. The French data protection authority (CNIL) and German supervisory bodies meticulously audit user tracking methods. Implementing traditional monitoring tools that rely on collecting personal data without explicit consent can result in massive financial penalties under the EU AI Act and GDPR.

TrafficWatchdog addresses these requirements by applying a compliance by design approach. The parameters collected by the script are used solely for security purposes (fraud detection) and are fully anonymized. Consequently, deploying Click Scanner does not require complex modifications to cookie banners and is entirely safe for your company's reputation and finances in every EU country.

Step-by-Step Implementation of Click Scanner

The system deployment process has been designed to minimize IT department involvement and reduce setup time to just a few minutes.

Step 1: Tracking Code Implementation

The foundation of the system is placing an asynchronous JavaScript script on the landing page. The code can be deployed in two ways:

• Directly in the HTML code of the website (in the <body> section).
• Via Google Tag Manager (GTM) – a convenient solution, though it is worth noting that ad blockers can sometimes delay or block GTM loading (which can generate discrepancies of 5–15%).
• For popular e-commerce platforms (Shoper, WooCommerce, IdoSell), dedicated plugins are available for one-click installation.

Step 2: API Connection or Remarketing Lists Configuration

To automate IP blocking in Google Ads, approve the manager account invitation sent from the TrafficWatchdog system. If you prefer protection without API access or are advertising on Facebook, configure the TWD remarketing list exclusion in your Google/Meta ad panel.

Step 3: Defining Rules and Blocking Thresholds

Working together with the TrafficWatchdog team, optimal blocking rules are selected (e.g., limit of visits from a single IP/fingerprint within a specific timeframe). After gathering a data sample (typically 7–30 days), the system analyzes the correlation between suspicious activity and conversions, eliminating the risk of blocking real customers.

Step 4: Downloading Claim Reports

If a significant volume of invalid clicks (classified as FAKE or WORTHLESS) is detected, the online dashboard generates ready-to-use claim reports. You can submit these directly to Google Ads to request a refund for invalid activity charges.

Subscription Costs vs. Return on Investment (ROI)

Click Scanner is available in flexible packages tailored to the scale of your business, starting at just 1,000 clicks per month. The pricing packages are as follows:

• Starter: 300 PLN / month (up to 10,000 scanned clicks)
• Growth: 720 PLN / month (up to 40,000 scanned clicks)
• Pro: 1,200 PLN / month (up to 75,000 scanned clicks)

For larger volumes (above 100,000 clicks), the Affiliate Scanner is recommended (starting from 1,800 PLN / month), which additionally protects attribution against cookie stuffing and click hijacking.

Calculating cost-effectiveness is straightforward. If your monthly Google Ads budget is 10,000 PLN and your average cost-per-click (CPC) is 2.50 PLN, then with a minimal, conservative 10% ad fraud rate, you are losing 1,000 PLN every single month. Implementing the Starter package for 300 PLN not only saves these funds but also feeds clean data to Google's algorithms (such as Smart Bidding or Performance Max), preventing them from learning from false conversion signals.
