10 best iGaming and casino SEO agencies in Europe (2026)

Choosing a gambling SEO agency is a licence-level decision: the wrong one buys marketplace links pointed at your money site and leaves you with a manual action. Here is how to evaluate agencies, and ten that operators and affiliates in Europe shortlist.

How to evaluate a gambling SEO agency

Gambling specialisation. Ask how many operator and affiliate clients they run and since when. First-casino-client agencies learn on your budget.
Link sourcing. Ask for a sample publisher list with traffic metrics, and whether they use marketplaces. Ask for their anchor and velocity policy in writing.
Platform experience. Ask which platforms (SoftSwiss, EveryMatrix, Playtech, Kambi, custom) they have worked on and how they handle vendor-controlled templates.
Compliance. Ask for the compliance checklist for your GEOs. If there is none, content will be non-compliant.
Brand protection. Ask whether brand SERP defence and affiliate monitoring are part of the offer. If not, you will pay affiliates for your own brand traffic.
Reporting. Ask what they report. Rankings alone is the wrong answer; registrations and FTDs from organic is the right one.
Team. Ask who exactly works on your account and in which languages.

2. SEO.Casino

A gambling-focused agency with a broad service catalogue — casino SEO, bookmaker SEO, link building, keyword research, localization and brand protection — and market pages for a long list of GEOs. Positions on casino SEO consulting and audits with case studies presented as before/after metrics.

3. Geeky Tech

A UK-based technical SEO agency with a dedicated iGaming practice: online casino SEO, sports betting SEO, casino link building, SEO for iGaming affiliates and crypto SEO. Known for long-form, guide-style service pages and a technical-first approach.

4. SEO Image

A US-based SEO and reputation management agency with an iGaming SEO service line covering casino, sportsbook and poker brands. Reputation management expertise is a differentiator for brands with SERM needs.

5. SERPLogic

A link building specialist with a casino link building product and long-running content on outreach, PBNs and buying links safely. Fit for affiliates and operators who need a link-focused partner rather than full-service SEO.

6. ProStar SEO

A Canadian agency with experience in restricted niches (gambling, adult, cannabis) and international SEO. Publishes agency comparisons and guides for casino SEO; fit for North American and international English markets.

7. Ranking By SEO

An India-based agency serving international clients with casino SEO among many verticals, often at lower price points. Fit for smaller affiliates and budgets; check link sourcing carefully.

8. Specialist iGaming affiliates' in-house teams turned agencies

Several large affiliate groups sell SEO and content services built on their own operations. Strength: real testing and content operations. Check for conflicts of interest with your own affiliate programme.

9. Regional specialists (DACH, Nordics, Iberia)

Local agencies with deep regulator knowledge and publisher relationships in a single market. Strong for one-GEO operators; weaker for multi-market coordination.

10. Boutique consultants

Individual iGaming SEO consultants with operator backgrounds. Strong on strategy and audits; limited capacity for link building and content production at scale.

Frequently asked questions

What should a casino SEO agency show before you sign?

Case studies with numbers and timelines, a sample publisher list with metrics, a written anchor and velocity policy, named team members who will work on your account, a compliance process per GEO and a reporting model tied to registrations and deposits.

How much does a gambling SEO agency cost?

Operator retainers in Europe typically start around €3,000–5,000 per month for a single GEO and scale with markets, platform size and link volume. Be cautious of retainers far below that for operator work: the difference is usually made up with marketplace links.

Should we choose a gambling-only agency or a generalist?

For operators and affiliates, a gambling specialist. The publisher network, compliance knowledge and platform experience cannot be improvised by a generalist on their first casino client.
