The Internet Pioneers Discovery and Growth for Illegal Gambling Sites

13 October 2026

Technology and internet channels are key discovery and acquisition routes for illegal gambling platforms, with search engines, social media, affiliate sites, and mirror sites all playing a significant role in driving traffic. A 2023 report found more than 5.4 billion visits to the top 15 illegal gambling platforms and 40 mirror sites over a 12-month period.

Direct Traffic the Dominant Referral

Direct traffic was the largest source of user engagement, accounting for 66% or 3.575 billion visits. However, search engines emerged as a critical discovery channel, with 652 million visits, as Google dominates more than 92% market share.

The Role of Social Media

Social media advertising accounted for 22% of first points of contact while sponsorships made up 13%. Industry reports highlight how online gambling marketing increasingly uses social media platforms to promote products and brand names. There is growing usage of online sports betting platforms to reach a wider audience. Vulnerable populations, particularly young people, are at high risk of exposure to gambling marketing.

SEO and Referrals Drive Offshore Gambling

A U.S.-focused study revealed that the online visibility of offshore gambling sites is a key predictor of U.S. player use. Organic keywords and referring domains were significant indicators of website traffic. Strong online visibility increases the chance of customers encountering these platforms through online reviews and Google searches.

Affiliates and Unlicensed Operators

The Swedish Gambling Authority reported that marketing and traffic steering are key mechanisms used to attract players to the unlicensed market. Affiliate and comparison sites play a significant role in driving traffic to unlicensed gambling platforms.

Illegal Tactics and Blocking Challenges

With mirror sites, encrypted communications, and anonymous payment methods, offshore operators evade detection. VPNs, proxy DNS, and alternative DNS services lower access barriers. Illegal gambling sites can shift to other internet addresses to evade blocks, posing challenges for effective disruption efforts by internet service providers.

Evidence from Regulators

The U.K. Gambling Commission identified nearly 450,000 Bing and Google URLs referring traffic to illegal gambling platforms, with 339,757 related to Google alone. The regulator observed an average 32% decrease in engagement across 160 websites post-disruption activity. In Sweden, nearly 1,100 unlicensed gambling sites attracted significant traffic from within the country. Furthermore, a 2024 report found unlicensed operators taking 70% of Europe's online gambling money, with 90% of clicked gambling content promoting unlicensed sites.

The internet functions as the primary acquisition layer for many illegal gambling platforms, with search, social media, and affiliates intersecting to drive significant traffic. While regulatory efforts show promise in disrupting engagement, the industry's rapid adoption of technical workarounds necessitates continued vigilance and innovation in blocking and traffic monitoring. With the online gambling marketing landscape evolving rapidly, stakeholders must remain proactive in addressing illegal activities and safeguarding vulnerable populations.
