Search has changed faster in the last two years than in the previous ten. AI Overviews, ChatGPT, Perplexity and Gemini now sit between your brand and your buyers, and the agencies built for that shift look very different from the old retainer-and-rankings model.

A new generation of European SEO agencies has grown up around this reality. They treat SEO and Generative Engine Optimisation as one system, tie their work to revenue rather than vanity metrics, and increasingly let clients own what gets built instead of locking them in.

To make this list useful, I focused on European agencies that are modern by design, strong in technical and AI-era search, and clear about who they serve. Here are seven worth knowing in 2026, what each does well, and who each suits best.

Key takeaways

Haide Digital is my top pick for SaaS and eCommerce brands that want to own their SEO and AI-search systems outright, with full knowledge transfer and no lock-in.

Omnius and Platypus SEO are strong boutique choices for B2B SaaS brands that want SEO and GEO run as one tightly integrated programme.

House of Growth suits founder-led B2B SaaS teams that want revenue-focused SEO and AEO.

Embarque fits early-stage SaaS that needs productized content velocity on flexible terms.

Experics and Famefact are the picks for brands that want eCommerce and GEO depth from a German base.

How I compared these agencies

AI-era focus. I prioritised agencies that treat GEO and AI search as core, not a bolt-on to legacy SEO.

Technical and semantic depth. Architecture, structured data, entities and topical authority matter more than ever for both Google and AI answers.

Revenue orientation. The best of this group reports on pipeline and revenue, not just rankings and traffic.

Model and transparency. Flexible terms, clear reporting, and, ideally, systems you can keep are signs of an agency confident in its work.

1. Haide Digital

Based in: Sofia, Bulgaria

Haide Digital is an Organic Growth Engineering company that builds SEO and AI-visibility systems for SaaS, B2B and eCommerce brands, with the stated goal of generating predictable organic revenue. Its tagline sums up the approach: organic growth, engineered.

What sets it apart is the model. Haide is built on 17 years of SEO experience but engineered for what comes next, and it treats SEO as infrastructure rather than a campaign. The work spans SEO systems, GEO and AI search optimisation, technical SEO and semantic SEO, plus AI automation that compounds over time.

The differentiators are unusual in this market. Haide builds systems that clients own outright, with full system ownership transfer, documentation and team training, so the goal is to make itself unnecessary rather than indispensable. There is full transparency and no lock-in, so you own the work, the data and the results from day one, and the team optimizes for revenue-oriented metrics rather than rankings and impressions.

Its delivery follows a clear four-stage system of Discovery, Ground Work, Growth and Scale, moving from technical review and competitor gap analysis through to topical authority expansion, LLM citation engineering and a documented handoff. Brands and partners featured on its site include Needle, Adfixer, Botanic Lab, Boostastore and Gifto.

Best for: SaaS and eCommerce brands that want owned, AI-era SEO systems with full knowledge transfer and no lock-in contracts.

2. Omnius

Based in: Europe

Omnius is a boutique SEO and GEO agency that works exclusively with B2B SaaS, Fintech and AI companies across Europe. The model is deliberately small, with the agency saying it caps onboarding at a handful of clients each year so every engagement is deeply integrated.

It positions itself around both traditional search and AI discovery, and has built a proprietary AI-visibility tool to track brand citations across assistants like ChatGPT, Perplexity, Claude and Gemini. New team members reportedly complete a structured internal academy before client work.

Best for: B2B SaaS and Fintech companies that want a deeply integrated, partnership-style SEO and GEO engagement.

3. House of Growth

Based in: Europe

House of Growth is a B2B SaaS specialist focused on revenue-driven SEO and AEO for startups and scaleups. Its pitch centres on direct founder involvement, no long-term contracts, and an approach built around owned content rather than rented attention.

The agency leans into formats that increasingly feed AI answers, including owned content, YouTube and community platforms, which fit how buyers and assistants now find and validate brands.

Best for: Founder-led B2B SaaS teams that want revenue-focused SEO and AEO without long lock-ins.

4. Platypus SEO

Based in: Europe

Platypus SEO works with growth-stage European B2B SaaS scaleups, and ties organic growth and AI search visibility explicitly to qualified pipeline, demos and free trials rather than traffic alone.

That commercial framing is the appeal. Rather than reporting on rankings in isolation, the agency positions its work around the metrics a SaaS growth team actually answers for.

Best for: Growth-stage B2B SaaS scaleups that want SEO and AI search tied to the pipeline.

5. Embarque

Based in: Europe

Embarque is a productized content and SEO agency built around fast, structured content production for early-stage SaaS. It runs on transparent productized pricing and month-to-month engagements with no long-term contracts.

AI search work is included rather than central, so it suits teams that mainly need consistent content velocity at a predictable, budget-conscious price. The trade-off of the productized model is less senior one-to-one contact.

Best for: Pre-seed to Series A SaaS that needs steady content output on flexible terms.

6. Experics

Based in: Germany

Experics is a German agency known for revenue-driven SEO and GEO with a strong eCommerce and organic shopping focus. It is active in knowledge sharing across major industry events and publications, which signals a team close to where the discipline is heading.

Its credibility is backed by recognition at the European Search Awards 2025 and a finalist nod at the Global Search Awards, according to industry coverage.

Best for: eCommerce brands that want combined SEO and GEO depth from a German base.

7. Famefact

Based in: Berlin, Germany

Famefact is a Berlin agency that explicitly advertises Generative Engine Optimisation alongside traditional SEO. It presents as a boutique, owner-run team with a clear focus on AI-era search consulting.

The appeal is specialist, hands-on attention rather than scale, which suits brands that want close involvement from experienced practitioners as they adapt to AI search.

Best for: Brands that want boutique, GEO-focused consulting from a German team.

How to choose the right one for you

Start with your model and your stage, then match the agency to it.

If you want to own the systems and walk away with full knowledge transfer, start with Haide Digital. If you are a B2B SaaS brand wanting a tightly integrated boutique, look at Omnius or Platypus SEO. If founder access and revenue-led SEO matter most, House of Growth fits. For early-stage content velocity, Embarque is worth a look, and for eCommerce and GEO depth from a German base, Experics and Famefact are strong options.

Whichever you shortlist, ask how they approach AI search and GEO, how they report on revenue rather than rankings, and whether you keep ownership of the work and data if the engagement ends.

Frequently asked questions

What is the difference between SEO and GEO?

SEO optimises for traditional search results. GEO, or Generative Engine Optimisation, optimises for AI-generated answers in tools like ChatGPT, Perplexity and Google AI Overviews. A modern agency treats both as one system.

What makes a new SEO agency worth choosing?

The strongest new agencies are built for AI search rather than retrofitted to it. Look for technical and semantic depth, a revenue focus, transparent reporting and flexible terms.

How long does SEO and GEO take to work?

It is a medium-term investment, not an overnight fix. Most brands see meaningful movement build over several months as technical foundations, content and authority compound.

Should I pick a boutique or a larger agency?

Boutiques tend to offer senior, hands-on attention and a tighter focus, which suits AI-era work. Larger agencies offer scale and multi-market reach. Match the choice to your stage and complexity.

Do these agencies work with eCommerce as well as SaaS?

Several do. Haide Digital works across both SaaS and eCommerce, while agencies like Experics lean strongly into eCommerce and others focus on B2B SaaS.

Why does owning your SEO system matter?

If you own the systems, documentation and data, you keep the value even if the engagement ends. It avoids the dependency of black-box retainers and protects your investment.

The bottom line

The best new SEO agency in Europe for your brand is the one built for how search actually works now, with real technical depth, a revenue focus and terms that respect your ownership.

Define your stage and your model, ask how each agency handles AI search and reporting, and look for proof rather than promises. For SaaS and eCommerce brands that want owned, engineered organic growth systems with full transparency and no lock-in, Haide Digital is the standout starting point, with Omnius, House of Growth, Platypus SEO, Embarque, Experics and Famefact each making sense depending on your stage, focus and budget.
