Casino.org leads the UK gambling affiliate rankings, while horse racing and sports betting websites account for much of the remaining traffic. New affiliate intelligence data reveals which websites attract the largest audiences and how their strategies differ.
The UK remains one of the world’s most established online gambling markets, with a competitive affiliate sector spanning online casinos, sports betting, horse racing and betting comparison services.
But which gambling affiliate websites attract the most traffic in the UK?
Based on the latest affiliate intelligence data for October 2026, Casino.org leads the rankings with an estimated 238,100 monthly visits, followed by HorseRacing.net and MyRacing.com.
The figures also reveal an interesting pattern: specialist sports betting and horse racing websites are competing successfully against broader gambling comparison platforms.

Casino.org Leads the UK Affiliate Market
With approximately 238,100 monthly visits, Casino.org occupies first place in the ranking, ahead of HorseRacing.net at 147,100 visits.
That gives Casino.org a traffic advantage of approximately 62% over the second-largest website in the dataset.
Casino.org operates in the highly competitive online casino affiliate segment, where operators compete for visibility across casino reviews, bonuses, payment methods and gambling-related searches.
Interestingly, the dataset associates Casino.org with just four tracked brands, substantially fewer than several competitors.
This illustrates an important distinction between affiliate traffic and the number of gambling operators appearing in a tracking dataset. A website’s audience size does not necessarily correlate with the number of brands identified by an intelligence platform.
Horse Racing Affiliates Are Among the Strongest Performers
One of the most notable findings is the strength of horse racing-focused websites. HorseRacing.net and MyRacing.com occupy second and third place, with estimated monthly traffic of 147,100 and 134,600 respectively.
Together, they generate approximately 281,700 monthly visits in the dataset, exceeding Casino.org’s traffic.
Other racing-related websites also appear among the top 20, including TheWinnersEnclosure.com and BritishRacecourses.org.
The prominence of these platforms highlights the importance of specialised gambling content in the UK market.
Unlike general casino affiliate websites, horse racing publishers can attract audiences through race previews, betting tips, racecards, form analysis and coverage of major racing events.
These formats can create recurring demand from users seeking information before placing bets.
For affiliate operators, this represents a potentially valuable source of traffic because visitors may return regularly rather than arriving only when researching a new gambling operator.
Sports Betting Websites Challenge Casino Affiliates
Sports betting websites also hold prominent positions. SportsGambler.com ranks fourth with approximately 86,740 monthly visits, while FootyAccumulators.com follows in fifth with 79,410.
SportyTrader.com occupies seventh position with 69,420 monthly visits.
These websites operate in content categories where predictions, odds analysis, football betting information and event-driven searches can generate consistent audience interest.
The UK’s strong football culture, combined with established horse racing and sports betting traditions, creates opportunities for publishers focusing on individual sports or betting formats.
The results suggest that specialist editorial coverage remains an important competitive strategy alongside traditional gambling operator reviews and bonus comparison pages.
Casino.Guru and AskGamblers Remain Major Casino Affiliate Websites
Among the best-known casino comparison and review platforms, Casino.Guru ranks sixth with 73,020 monthly visits, while AskGamblers occupies eighth position with 63,220.
Both have established identities within the international online casino affiliate sector.
Their presence in the UK top ten demonstrates that casino review platforms continue to attract meaningful audiences, even as sports betting and horse racing websites account for several of the leading positions.
However, traffic alone does not reveal commercial performance.
Casino affiliate visitors researching operators, payment methods or bonuses may have different conversion characteristics from sports betting audiences consuming predictions or race previews.
Consequently, traffic rankings should not be interpreted as revenue or profitability rankings.
Which Gambling Affiliate Tracks the Most Brands?
The dataset also provides information about the number of gambling brands associated with each affiliate. BettingOdds.com stands out with 41 tracked brands, the highest number among the top 20 websites.
HorseRacing.net follows with 32, while AskGamblers.com, BookiesBonuses.com and TheWinnersEnclosure.com each have 18.
The differences are substantial.
Casino.org leads the traffic rankings with four tracked brands, while BettingOdds.com ranks eleventh by traffic despite having more than ten times as many tracked brands.
This suggests that traffic concentration and operator coverage are two different dimensions of affiliate market positioning.
It is important, however, not to interpret tracked brand counts as confirmed affiliate agreements or total commercial relationships.
The Top Five Websites Account for Nearly Half of Top-20 Traffic
Combined estimated monthly traffic across the top 20 websites reaches approximately 1.35 million visits. The five largest websites account for around 686,000 visits, representing approximately 51% of the top-20 total.
Casino.org alone contributes roughly 18% of that traffic.
This concentration indicates that a relatively small group of publishers attracts a substantial proportion of the audience measured within the leading affiliate websites.
At the same time, the presence of specialist publishers demonstrates that there are multiple approaches to building traffic in the UK gambling affiliate sector.
What the Rankings Reveal About the UK Gambling Affiliate Industry
Three important observations emerge from the data.
Specialist content can compete with broad affiliate platforms. Horse racing and sports betting publishers occupy several of the highest positions, demonstrating the traffic potential of narrowly focused editorial strategies.
More tracked brands do not automatically mean more traffic. The comparison between Casino.org and BettingOdds.com illustrates how differently websites can position themselves in terms of traffic and operator coverage.
Established casino affiliates face competition from multiple gambling verticals. Casino comparison websites remain important, but the leading traffic rankings include sports predictions, horse racing information and bookmaker comparison platforms.
For gambling operators evaluating affiliate partnerships, these findings reinforce the importance of looking beyond headline traffic figures.
Audience relevance, geographic targeting, player acquisition quality, conversion rates and regulatory compliance all matter when assessing the potential value of an affiliate relationship.
Outlook: Competition in UK Gambling Affiliate Marketing
The UK affiliate sector continues to offer opportunities for publishers capable of building specialist audiences and producing relevant, useful gambling content.
Search visibility, brand recognition, repeat readership and the ability to serve specific betting interests are all potential competitive advantages.
However, the rankings represent a snapshot of estimated traffic rather than a definitive assessment of business performance.
The largest website by audience is not necessarily the largest by revenue, player referrals or profitability.
As competition evolves, monitoring changes in traffic distribution, tracked operator coverage and the performance of specialist websites may provide useful insights into the direction of the UK gambling affiliate market.
Methodology
This analysis uses a one-month snapshot from an affiliate intelligence platform covering 397 affiliates in the UK gambling market, supplied in October 2026. Rankings are ordered by the platform’s estimated traffic figures.
The dataset also reports tracked gambling brands and tracked pages. These metrics are platform-specific and should not be interpreted as exhaustive counts of partnerships or website pages.
The figures have not been independently verified against the publishers’ own analytics. They should therefore be treated as indicative estimates rather than audited traffic totals.
