Comprehensive Research on Fraudulent Traffic in the iGaming Industry

Introduction

Fraudulent traffic has become one of the most serious challenges in digital advertising. It drains budgets, distorts performance metrics, and undermines campaign effectiveness across channels.

Global digital ad spend has already exceeded $600 billion per year. At the same time, fraud techniques continue to evolve. Programmatic advertising, mobile campaigns, and automated delivery systems remain primary targets. Industry research suggests that by 2025, global losses from ad fraud could reach $100 billion annually.

For iGaming, the risk is even higher.

With global online gambling revenue projected to exceed $100 billion by 2025, fraudulent traffic directly impacts acquisition efficiency. Budgets leak into fake installs, manipulated conversions, and artificial engagement. Understanding the scale of fraud - and its operational impact - is essential for protecting performance and long-term growth.

This research examines the financial cost of ad fraud in iGaming, the most common fraud schemes, and the strategies required to mitigate them.

The Financial Toll of Ad Fraud in iGaming

Ad fraud losses continue to grow across all major digital channels. iGaming brands, heavily dependent on performance-based acquisition, remain among the most targeted.

Key figures highlight the scale of the problem:

• Global ad fraud losses: Estimated at $81 billion in 2022, projected to reach $100 billion by 2023

• iGaming-specific fraud: Over 25% of affiliate and programmatic traffic is estimated to be fraudulent

• Programmatic advertising: More than 20% of impressions are invalid due to bots, domain spoofing, and ad stacking

• Mobile advertising fraud:

  • iOS installs: ~31% fraudulent

  • Android installs: ~25% fraudulent

• Regional impact:

  • Asia-Pacific: nearly $75 billion in annual losses

  • North America and Europe remain highly targeted

Marketing Channels Most Affected in iGaming

• Affiliate marketing: ~14.3% fraud rate due to fake clicks and registrations

• Programmatic advertising: ~12.2%, driven by bots and hidden placements

• Search engine marketing (SEM): ~4.4% from click spam and fake sign-ups

• Native advertising: ~2.6%, largely from domain spoofing

• Social media advertising: ~2% fraudulent traffic

By 2025, global mobile ad spend is expected to reach $798.7 billion, further increasing exposure to fraud for iGaming advertisers.

These losses do more than reduce efficiency. They fuel a growing underground economy that incentivizes increasingly sophisticated fraud operations.

Common Fraudulent Tactics in iGaming Advertising

Fraud in iGaming takes multiple forms, each designed to manipulate attribution, inflate metrics, or simulate real user behavior.

Click Injection

Fraudsters generate artificial clicks just before an app install occurs. Malware intercepts legitimate installs and redirects attribution to fake sources. This tactic is especially damaging in mobile iGaming campaigns.

Click Spam

Large volumes of low-quality or fabricated clicks flood ad networks. CPC models become distorted, and budgets are consumed without real user intent.

Ad Stacking

Multiple ads are layered within a single placement. Only one is visible, but impressions are counted for all. Advertisers pay for inventory that users never see.

Domain Spoofing

Low-quality or fraudulent sites impersonate premium publishers. iGaming brands believe they are buying high-value inventory, while ads run on non-viewable or fake domains.

Bot Traffic and Fake Engagement

Bots simulate human behavior by clicking ads, visiting landing pages, and creating fake accounts. Studies show that 47% of all internet traffic comes from bots, with nearly 30% classified as malicious.

Fraud in User Acquisition Campaigns

• Fake depositing users simulate real payment behavior

• Affiliate fraud inflates sign-ups to claim commissions

• The financial impact runs into billions annually for iGaming operators

The Business Impact of Fraudulent Traffic on iGaming Brands

Fraudulent traffic affects more than spend efficiency. It undermines decision-making across the entire acquisition funnel.

Distorted Analytics

Bot-driven engagement inflates CTRs, installs, and early events. Real user behavior becomes harder to identify. LTV models lose accuracy.

Budget Leakage and ROI Erosion

Nearly one-third of digital ad spend is exposed to fraud. Without strict controls, budgets are allocated to sources that never deliver real value.

Compliance and Brand Risk

iGaming operates under strict regulatory frameworks. Fraudulent traffic increases the risk of compliance violations, chargebacks, and reputational damage.
