The iGaming affiliate landscape is more competitive than ever, with hundreds of review sites, comparison services, live casino trackers, and betting ecosystems fighting for the top positions in Google’s search results. To determine which affiliates truly dominate the global market in 2025, we analysed three Ahrefs competitor tables (for Casino.org, Casino.com, and PlayUSA.com) along with the Bonus.com organic search overview.
By merging all sources, removing non-affiliates (news sites, operators, providers), and ranking solely by organic traffic, we arrive at the most accurate, data-backed Top 20 Casino Affiliate list available in the industry today.
This ranking gives a clear view into the power dynamics of the global SEO landscape — and reveals some surprising giants in emerging markets.

1. CasinoScores.com Emerges as the Global #1
The biggest revelation in the data is the scale of CasinoScores.com, which registers an extraordinary 2.3 million organic visitors per month.
This positions the site not just as an affiliate, but as one of the highest-traffic iGaming properties globally.
CasinoScores’ advantage comes from:
- real-time game show data
- live casino result tracking
- dominance in India, Bangladesh, the Philippines and Brazil
- extremely high informational intent traffic
Its growth highlights the explosive potential of live-data-driven affiliate models.
2. Casino.org Remains the Western Market Leader
Despite CasinoScores’ meteoric growth, Casino.org, with 1.6 million monthly organic visitors, remains the strongest authority in Western markets.
Its DR 81, decades-long link profile, and depth of editorial content still set the benchmark for casino review websites worldwide.
Casino.org remains the gold standard for:
- casino reviews
- gambling education
- brand comparisons
- responsible gaming information
3. The U.S. Betting Boom Reshuffles the Rankings
One of the clearest trends in the 2025 data is the increasing presence of U.S.-focused affiliate brands:
- GamingToday.com — 929K visitors
- PlayUSA.com — 109K
- Bonus.com — 73K
- WSN.com — 210K
- SportsbookReview.com — 162K
The ongoing expansion of state-regulated casino and sports betting has created significant new search demand, with American affiliate brands capturing a growing share of global traffic.
4. Legacy Affiliates Still Hold Strong Positions
Several long-established brands continue to dominate their niches:
- PokerNews.com — still the largest poker-driven affiliate
- OddsChecker.com — unmatched for sports odds comparisons
- WizardOfOdds.com — the most trusted source for RTP and mathematics
- OLBG.com — long-running UK community site
Their resilience proves that reputation, authority, and evergreen content still outperform short-term SEO tactics.
5. Surprise of the Year — The Rise of Next.io
The biggest surprise in this year’s ranking is the extraordinary rise of Next.io, now generating 451.9K monthly organic visitors. But the most important detail is why.
While Next.io is historically known as a B2B industry brand, the Ahrefs Top Pages data tells a very different story:
the site’s traffic explosion is overwhelmingly driven by U.S. Sweepstakes Casino reviews.
According to the Next.io top pages report Top pages:
- Crown Coins Casino generates 92,810 visitors
- Zula Casino generates 46,569
- Spree Casino generates 28,704
- LuckyLand generates 27,809
- McLuck generates 25,194
- Pulsz and Pulsz Bingo add another 26K+ combined
- Dozens of other sweepstake reviews add thousands more
More than 90% of Next.io’s organic traffic now comes from the sweepstakes vertical.
Next.io isn’t accidentally capturing organic traffic through B2B authority. It has intentionally entered the U.S. sweepstakes casino market and is now one of its biggest search players.
This is the true surprise of 2025: A major B2B media brand has reinvented itself as a top-tier consumer-facing casino affiliate — and it worked.
6. Rising Mid-Tier and Specialist Platforms Gain Momentum
The mid-tier is increasingly dominated by hybrid or niche platforms:
- Chipy.com — community-driven casino ecosystem
- VegasSlotsOnline.com — slot-focused database
- FreeSlotsHub.com and SlotoZilla.com — free-to-play slot specialists
- TheSportsGeek.com — hybrid betting and casino advice
- Bonus.com — U.S. welcome bonus expert site
These properties demonstrate the growing demand for specialised casino content in 2025.
Final Thoughts: A Market Defined by Diversification
The 2025 iGaming affiliate landscape is no longer dominated by a handful of legacy brands. Instead, it is shaped by:
- Live data platforms (CasinoScores)
- Evergreen authorities (Casino.org, WizardOfOdds)
- U.S.-focused regulatory portals (GamingToday, PlayUSA, WSN, Bonus.com)
- Niche slot ecosystems (VSO, SlotoZilla, FreeSlotsHub)
- Global content engines (PokerNews, Next.io, OddsChecker)
This Top 20 ranking shows an industry where innovation, niche positioning, and regional targeting increasingly outperform traditional review-only approaches.
