Most sports bets are now placed on a phone, and many new players discover betting and casino brands through a mobile search that is increasingly answered by AI. That makes SEO a key acquisition channel for operators and affiliates.
SEO in the iGaming industry is also technically demanding, with a need to master mobile Core Web Vitals, app-store crossover, compliance-bound content and a link market that often declines gambling content.
This guide looks at ten agencies working in the iGaming SEO space and what each agency does well.
How this list was compiled
Rankings are calculated from iGaming specialisation, mobile and technical SEO capability, link building strength, compliance experience, transparency and publicly visible expertise. Self-reported metrics are flagged, and we deliberately looked beyond the same three names that appear in every agency’s self-published list.
1. Big Pond Digital
Topping the list is Big Pond Digital, a Scotland-based firm that works exclusively in iGaming SEO; no e-commerce or SaaS accounts, just casinos, sportsbooks and affiliates, served since 2011 across regulated and grey markets internationally.
The agency has over 60+ iGaming clients, boasts a +340% average organic traffic growth and a 5/5 Google review score from happy customers. It earns the top spot here largely on its mobile-relevant strengths.
Their SEO toolkit is designed around the nuances of mobile iGaming:
- Technical SEO audits run beyond 200 checks with strong focus on Core Web Vitals and mobile performance, which are decisive factors when most bettors land on a betting site from a phone.
- Content is produced by betting experts who write within compliance boundaries while building topical authority.
- Link building is the agency’s main speciality, securing high-authority placements from gambling publishers via bespoke outreach, which is the biggest challenge in this field.
- A dedicated brand protection practice stops affiliates hijacking operator brand searches, a problem that hits new betting apps hardest.
Two further dedicated services provide one of the most comprehensive SEO packages available: sportsbook SEO, where Big Pond ranks among the very top results on Google itself. This covers odds pages, match previews and event coverage for major markets from Canada to South Africa, and iGaming SEO for slots, live casino and bonus pages. You can reads their published case studies to verify the results they have delivered.
The team also shares valuable SEO insights on the iGaming SEO Show, a biweekly video podcast covering algorithm updates, affiliate tactics and AI search.
Best for: mobile-first sportsbooks, casino apps and affiliate sites that want an SEO partner with expertise in gambling compliance, links and mobile performance.
2. Click Intelligence
A UK SEO and link building agency whose client portal gives betting brands real-time visibility of keywords, backlinks and campaign progress. White-hat link acquisition for hyper-competitive terms like “slots” and “sports betting” is the headline service.
3. ICS-digital
With SEO and content delivered in 80+ languages from their base in Leeds, ICS-digital excels at localisation, so it is the practical choice when a betting app launches across multiple regulated markets and needs native-quality content and digital PR everywhere at once.
4. Stack Digital
Performance-led and focused on user intent, Stack has driven top-five rankings for BetDaq Exchange and Sportnation.bet by targeting the searches bettors actually make on their phones: live odds, event previews and localised bonus codes.
5. Blueclaw
One of the UK’s longest-running iGaming agencies, with casino, poker, bingo and sportsbook campaigns across Europe, Asia, the Americas and Australasia, and multi-channel support beyond SEO. They have a solid reputation, making them a safe choice for established operators.
6. Ignite iGaming
Founded by former bet365 and Ladbrokes marketing leaders, Ignite builds SEO around the metrics operators actually report, such as first-time depositors, CPA and player lifetime value, rather than raw sessions.
7. SEO.Casino
A casino-only boutique agency with around 14 years in the niche, covering technical SEO, content and gambling link building across tier-one and emerging markets.
8. Reboot Online
Reboot Online are digital PR specialists known for data-led campaigns that earn gambling sites links from mainstream media, the kind of authority that does not get impacted by algorithm updates. The company is a good option when referring-domain quality is the main issue.
9. Interamplify
An enterprise international SEO firm with compliance infrastructure for UKGC and US state-by-state rules, using AI-assisted tech to deliver at scale. This choice suits multi-jurisdiction sportsbooks with heavy governance frameworks to comply with.
10. Growth Gorilla
A focused iGaming growth agency combining technical SEO, intent-driven content and authority link acquisition, with strategies designed around revenue and player acquisition rather than traffic for its own sake.
Choosing an SEO partner for a betting app or site
• Prioritise mobile technical depth: ask how the agency handles Core Web Vitals, JavaScript rendering and page speed on game-heavy pages.
• Verify sportsbook-specific experience: odds pages and event content behave differently from casino SERPs.
• Insist on link transparency and gambling-publisher relationships: cheap links are a risk here.
• Ask which AI engines currently recommend their clients: AI answers are the new front page of mobile search.
