Best SEO & Generative Engine Optimisation (GEO) Agencies in Europe

Finding the best SEO and Generative Engine Optimisation (GEO) agencies in Europe has become a genuinely harder decision in 2026 than it was two years ago. The problem is not a shortage of agencies. It is that the vast majority of European agencies claiming GEO capability have simply relabelled their existing SEO retainers. The work underneath those service pages, in most cases, has not changed.

What has changed is buyer behaviour. According to G2’s 2025 Buyer Behavior Report, 51% of B2B software buyers now begin vendor research inside AI chatbots more often than Google. For European tech startups and B2B SaaS companies, that number has a direct commercial consequence: if your brand is not cited when a buyer asks ChatGPT or Perplexity for a vendor recommendation in your category, you are invisible at the moment the shortlist is being formed.

We reviewed more than 30 European agencies against a consistent standard: a published, named methodology, multi-platform AI tracking, verifiable case studies with specific metrics, and documented B2B or SaaS focus. Not every agency that “offers GEO” in 2026 has actually built it. Seven of the agencies we reviewed have. Here is what the field looks like.

Top 3 at a Glance

Agency Best For Starting Price
GrowPad Seed–Series C B2B SaaS and tech startups across EU, full SEO + GEO stack $3,000+/mo
Omnius B2B SaaS and fintech companies needing specialist 22-point GEO €5,000+/mo
Discovered Labs Tech startups invisible in ChatGPT needing rapid AEO citation gains €5,495+/mo

How We Evaluated These Agencies

We reviewed more than 30 GEO SEO agencies operating across European markets. Agencies were removed for any of the following: no named GEO or AEO methodology, no verifiable case study with specific AI-search metrics, fewer than ten third-party reviews or equivalent credibility signals, or evidence they simply added “GEO” to a service page in 2024 without changing their delivery.

The six criteria we weighted were:

  1. Published SEO + GEO methodology — a named framework with documented steps, not a service page headline
  2. Verified case studies with specific metrics — named or clearly described client, before-and-after data, direct link to the page
  3. B2B SaaS and tech-startup fit — understanding of subscription revenue, long sales cycles, and product-led funnels
  4. Multi-platform AI tracking — coverage across ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews
  5. Review depth and recency — Clutch, Google Business, or equivalent with active 2025–2026 review activity
  6. Awards, certifications, or partner status — Google Partner tiers, search awards, industry certifications

Agency Profiles

1. GrowPad — Top SaaS GEO And SEO Agency Across Europe

GrowPad - geo seo agencies

GrowPad is an inbound growth agency built exclusively for SaaS and B2B tech companies, with its EU headquarters in Alicante, Spain. It is the highest-rated agency on this list by verified Clutch reviews — 5.0 stars across 38 reviews — and the only one whose entire Clutch profile covers SEO, GEO, and link building exclusively, with no unrelated service lines diluting the review pool.

The agency’s methodology is structured around four pillars that work together: traditional SEO for Google ranking foundations, LLMO (Large Language Model Optimisation) for brand citations in ChatGPT and Perplexity, GEO for off-site entity signals that influence AI recommendation, and AEO for on-site content structured for direct AI extraction. When we reviewed GrowPad’s engagement model during our analysis, the key differentiator is that these are not sold as separate retainers — they run as one system, because Google, ChatGPT, and Perplexity all draw from overlapping authority signals.

The agency has served 60+ SaaS clients across the EU and US. Every link placement goes through a three-point validation — domain relevance, traffic quality, and editorial standards — before it goes live. GrowPad focuses on one vertical at a time per client until it dominates, which they describe as the mechanism behind a 73% first-page ranking rate within 90 days on priority pages.

Industries: SaaS, B2B tech, fintech, HR tech, martech, e-learning, healthcare software, IoT

Core Services:

  • SEO strategy and technical implementation
  • LLMO — citation building and tracking across ChatGPT, Perplexity, Gemini, Claude, and AI Overviews
  • GEO — entity authority and off-site brand signals for AI recommendation
  • AEO — structured on-site content for direct AI extraction
  • Validated SaaS link building
  • Standalone AI Search Audit (entry-point engagement, no retainer required)

Client-Fit Profile: GrowPad works with B2B SaaS and tech companies from pre-seed through Series C. Typical client ARR runs from $500K to $20M. They operate primarily in English and serve clients across the US and Europe. Pain points addressed: traffic that doesn’t convert to demos; organic pipeline stagnating despite good rankings; zero presence in AI search results while competitors appear consistently.

Awards & Status: Four Clutch distinctions for 2026: Top SEO Company — Information Technology, Top SEO Company — SaaS, Top SEO Company — Spain, Top Link Building Company — Spain. The Clutch profile shows 38 verified reviews at 5.0 stars with review activity dated 2026. GrowPad also published primary research surveying 110 marketing leaders from IT, SaaS, and consulting companies across Europe, available in their 2026 LLMO and Inbound Marketing Report.

Verified Case Study — Logistics Software (B2B tech, EU): A custom logistics software development company came to GrowPad with fragmented AI visibility — the brand appeared in some LLM responses but held no stable position across priority buyer prompts. GrowPad built cluster-by-cluster AI visibility through entity optimisation, third-party citation engineering, and LLM-ready content architecture. Within 90 days, brand and domain mentions across LLMs grew from approximately 75 to 586 mentions per month — a 7–8× increase. ChatGPT visibility grew from zero to 238 brand mentions within a single month. The brand reached top-1–2 positions in ChatGPT, Perplexity, and Google AI Overview for priority logistics-tech prompts. The CMO of the company (NDA) noted that GrowPad focused on “concrete steps and priorities rather than high-level theory” and described the results as showing “a clear positive trend” from the first stable inbound leads.

Pricing: $50–99/hour; $3,000–$10,000/month. €1,000+/month for EU startups. Minimum budget $3,000/month.

Our Take: GrowPad is the top SaaS GEO agency for tech startups on this list when SEO, AI citations, and pipeline growth need to operate as one system. The 5.0★ Clutch rating across 38 recent reviews, the four 2026 Top badges, and the documented LLMO case study with specific before-and-after citation numbers place it ahead of the field for the specific brief this list addresses.

Best for: B2B SaaS and tech startups at $500K–$20M ARR across Europe wanting SEO and AI citation built simultaneously rather than sequentially.

Not ideal for: Teams wanting a hands-off passive vendor; companies outside B2B SaaS and tech; consumer-facing brands.

2. Omnius — Best for B2B SaaS and Fintech Companies Needing Specialist GEO

Omnius - top geo seo agencies

Omnius is a European B2B SEO and GEO agency that partners exclusively with SaaS, fintech, and AI companies. The agency is based across London, Dubai, and Belgrade. When we evaluated Omnius during our research, the detail that stood out most was the 22-point GEO process — covering everything from llms.txt file configuration and JavaScript trimming for AI crawlers to citation engineering and multi-channel authority building across Reddit, Quora, G2, and Gartner Peer Insights.

The agency built AtomicAGI — a proprietary real-time AI citation tracking tool — in early 2024, giving clients structured measurement of citation frequency across ChatGPT, Claude, Perplexity, and Gemini. This infrastructure existed before most European agencies understood what they were measuring.

Industries: SaaS, fintech, AI — exclusively. B2C, ecommerce non-SaaS, and agencies are explicitly excluded.

Core Services:

  • B2B SEO strategy and technical implementation
  • 22-point GEO programme (entity authority, AI crawler access, citation engineering)
  • LLMO with AtomicAGI proprietary citation tracking
  • Multi-channel authority building (Reddit, Quora, G2, Gartner, LinkedIn)
  • Content strategy aligned to LLM citation patterns
  • 8 clients accepted per year — capacity is not guaranteed

Client-Fit Profile: Omnius serves European and global SaaS and fintech companies. Named clients include ANNA Money (Deloitte UK Fast 50, $88M+ raised), TextCortex (G2 Top AI Product 2025), Myos (€47M+ raised), AuthoredUp (G2’s #1 LinkedIn Tool 2025), and Signify. They work with growth-stage and scale-up companies. The annual 8-client cap is real — prospective clients undergo a fit assessment before a proposal is issued.

Verified Case Study — AuthoredUp (B2B SaaS): Omnius rebuilt AuthoredUp’s Webflow site and deployed a full SEO and content strategy. Organic clicks grew from 400/day to 1,600+/day. Daily signups grew from 65 to 180+. Over 3.5 months, Omnius helped generate 2,600+ signups and 64% higher conversion rates, with 110% organic growth in six months. This is the most directly relevant published case study from their library for European B2B SaaS startups.

Pricing: Custom — contact for quote. No published tiers. Expect mid-to-upper market rates given the exclusive model and 8-client cap.

Our Take: Omnius earns its place for European B2B SaaS and fintech companies that need genuine GEO depth, not a rebranded SEO programme. The 22-point GEO framework, the AtomicAGI tracking infrastructure, and the SaaS/fintech exclusivity all stand up under scrutiny. The limited Clutch presence is the main gap for buyers who rely on third-party verified social proof — ask directly for client references during scoping.

Best for: European B2B SaaS and fintech companies at growth or scale-up stage wanting specialist GEO with proprietary citation tracking.

Not ideal for: Companies outside SaaS/fintech/AI; startups needing fast onboarding given the annual client cap.

3. Discovered Labs — Best for B2B Tech Startups Invisible in ChatGPT and Perplexity

Discovered Labs - seo geo agency

Discovered Labs is a Dublin-based generative engine optimisation agency and a specialist GEO agency for startups that need rapid AI citation growth. An ex-Stanford AI researcher who built fraud detection systems at Stripe, Coinbase, and Brex, and Liam Dunne, who helped scale Instantly.ai to $20M ARR in three years. The founding pair is the agency’s most credible signal: a machine learning engineer who understands how LLMs retrieve information, combined with a demand generation practitioner who has scaled B2B SaaS pipeline from zero.

During our research, we identified content velocity as the agency’s most specific structural differentiator. GEO requires roughly double the publishing cadence of traditional SEO, daily or near-daily output, to consistently feed AI models fresh, structured content with topical authority signals. Discovered Labs is built for this cadence. Most traditional SEO agencies are not.

Industries: B2B SaaS, professional services, technology

Core Services:

  • AEO with the proprietary CITABLE framework (7-part methodology for LLM-citable content)
  • Daily content production — 20+ articles per month
  • AI citation tracking across ChatGPT, Claude, Perplexity, and Google AI Overviews
  • Competitor AI citation monitoring
  • Technical audits for AI crawler access (llms.txt, robots.txt, structured data)
  • Reddit community marketing
  • Month-to-month contracts — no lock-in
  • GEO services for startups, including technical AI-access audits, citation tracking, content production, and competitor monitoring

Client-Fit Profile: Discovered Labs targets hypergrowth Series A+ B2B SaaS companies. The founders describe their ICP as brands that rank fine on Google but are simply absent when buyers ask AI tools for vendor recommendations. For European tech startups that have built Google traffic but are not showing up in AI answers, this is the most specific mandate fit on this list. Engagements run in English.

Verified Case Study — Project Management SaaS (B2B, EU): A B2B SaaS company at $25M ARR was appearing in only 8% of buyer queries on ChatGPT and Perplexity, while competitors dominated 65% of those recommendations. Discovered Labs shipped 66 optimised articles in seven weeks, fixed critical technical AI-access blockers, and applied the CITABLE framework. Citation rate grew from 8% to 24% in 90 days. The engagement generated 47 AI-referred leads converting at 2.8x the traditional organic rate, with €64,000 in closed revenue and a 288% ROI in a single quarter.

Pricing: €5,495+/month. Includes 20+ SEO and AEO-optimised articles, AI visibility tracking, competitor monitoring, monthly strategy reviews, technical audits, backlink building, and Reddit marketing. Month-to-month contracts.

Our Take: Discovered Labs is the strongest pick for B2B tech startups that are ranking on Google but simply absent from AI-generated vendor shortlists. The month-to-month contract structure signals confidence — most agencies lock clients into six to twelve months. The technical depth of the founding team is real and distinguishable from agencies that read about LLMs and produce content playbooks.

Best for: Series A+ B2B SaaS and tech startups that want to move from invisible to recommended in AI answers within 90 days.

Not ideal for: Pre-product-market fit companies; teams needing German- or French-language content; companies outside B2B SaaS.

4. DREIKON — Best for DACH B2B Tech Companies and Regulated Sectors

DREIKON - generative engine optimisation agency

DREIKON provides comprehensive GEO and SEO consulting services for B2B companies in Germany, Austria, and Switzerland. Its co-authorship of DIN SPEC 33461, Germany’s national standardised methodology for search engine optimisation, published with the German Institute for Standardization in 2024 is the single strongest third-party quality credential of any agency on this list. When we assessed DREIKON during our research, this is the agency for which the question “is their GEO methodology documented?” has the most defensible answer: they co-authored a national standard that defines what documented SEO methodology looks like.

The agency holds Google Premium Partner status, placing it in the top 2% of approximately 800 SEO service providers in Germany. It operates under the BVDW (Federal Association of the Digital Economy) Code of Conduct SEO and holds the BVDW SEO Specialist Certificate. Three team members hold TÜV Rheinland-certified sales psychology qualifications — an unusual combination that the agency explicitly integrates into its client-side content strategy.

Industries: B2B professional services, DACH mid-market, manufacturing, regulated sectors

Core Services:

  • GEO and SEO services for startups and mid-market B2B companies entering the DACH market
  • Sales psychology consulting integrated into content and landing page strategy
  • Performance marketing (SEA, Google Ads)
  • Social media and content production
  • Month-to-month contracts, no performance-fee models, no ranking guarantees

Client-Fit Profile: DREIKON serves the DACH market — Germany, Austria, Switzerland — working with mid-market B2B companies across professional services, manufacturing, and regulated sectors. Their operating principle is explicit: they advise against measures that are not promising. For B2B tech startups scaling in the German-speaking market, the DIN SPEC 33461 involvement and the BVDW certifications provide structural quality assurance above any marketing claim.

Awards & Status: DIN SPEC 33461 consortium co-founder (2024). BVDW Code of Conduct SEO member. BVDW SEO Specialist Certificate. Google Premium Partner. Ranked #1 GEO/SEO agency in Germany’s 2026 ranking from their own analysis. Multiple German Agency Prize wins from Agenturtipp and Feedbax. 5.0 Google Business rating across 54 reviews.

Verified Case Study: DREIKON’s client documentation is primarily available in German. Published results across B2B professional services and mid-market accounts are documented on their site. A specific named case study with quantified metrics in English was not found during our research — request this directly from the team when scoping a DACH engagement.

Pricing: €5,000+/month. Month-to-month contracts, no annual commitment, no success-based fees.

Our Take: DREIKON earns its position through regulatory and quality credentials that no other agency on this list can claim. For B2B tech startups or professional services companies targeting the German-speaking market — particularly those with compliance or professional advertising constraints — the DIN SPEC 33461 co-authorship and Google Premium Partner status provide guarantees that sit above any content marketing claim. The absence of a publicly quantified English-language case study is the primary gap to verify directly.

Best for: B2B tech startups and professional services companies scaling in Germany, Austria, or Switzerland wanting certified GEO/SEO with structural quality assurance.

Not ideal for: English-language-only mandates; companies wanting rapid, high-cadence content output.

5. Peak Ace — Best for International B2B Tech Brands Targeting Multiple EU Markets

Peak Ace - generative engine optimisation services in europe

Peak Ace was founded in Berlin in 2007 and operates from offices in Berlin, Paris, and Nantes with 170+ staff delivering campaigns in 25+ languages at native-speaker level. For B2B tech companies expanding across multiple European markets simultaneously, this multilingual and multicultural depth is the most practical differentiator on this list.

The award record is the strongest of any agency here by volume: nine European Search Awards and eight Global Search Awards in 2024, followed by three additional European Search Awards in 2025. In 2023, the agency was named SEO Agency of the Year at the European Agency Awards and Multi-Territory Agency of the Year — a specific recognition for the cross-market work that defines their model. When we evaluated this during our research, the Multi-Territory designation is directly relevant for European SaaS startups moving from single-country to multi-country expansion.

Industries: Enterprise SaaS, international B2B brands, travel, financial services

Core Services:

  • Multi-market SEO and GEO
  • Multilingual content marketing at native-speaker quality
  • PPC and paid performance marketing
  • Marketing technology and data analytics
  • AI solutions for cross-channel efficiency and predictive search

Client-Fit Profile: Peak Ace works with enterprise-scale brands including Airbnb, Sage, AutoScout24, TUI, and Luxair. In 2025, CWS Hygiene engaged them for a nine-market strategy covering Europe. The agency model suits large B2B tech companies and scale-ups with enterprise budgets and multi-country mandates. For earlier-stage startups, the capacity overhead of a 170-person agency may exceed their immediate need.

Verified Case Study — Freshworks (B2B SaaS, multi-market EU): For Freshworks, a B2B SaaS company struggling to gain traction in European markets, Peak Ace built a multi-country SEO programme. Freshworks’ marketing team reported a 150% increase in lead volume and a 60% reduction in cost per lead from the engagement. This is the most directly relevant published proof point for European B2B SaaS expansion from their client library.

Pricing: Custom — contact for quote. Enterprise-tier pricing.

Our Take: Peak Ace is the best GEO agency for European markets on this list when a company needs native-language execution across several countries. The 170-person multilingual team, the nine-market delivery capability, and the award record across both European and Global Search Awards are all verifiable. The limitation is fit — their model is built for enterprise scale, which means growing startups will pay for capacity they do not yet need.

Best for: Enterprise and scale-up B2B tech companies targeting multiple EU markets simultaneously, particularly where native-language content quality matters.

Not ideal for: Single-market tech startups; companies under €50M ARR needing a lean specialist partner.

6. Onely — Best for B2B Tech Startups With Complex Sites Needing Technical SEO + GEO

Onely - best ai search optimisation agency in europe

Onely is a technical generative SEO agency for B2B companies with JavaScript-heavy, headless, or otherwise complex websites. The Clutch profile shows 5.0 stars across 17 verified reviews, consistently cited by enterprise SEO practitioners as the specialist for JavaScript-heavy and large-scale sites. When we reviewed their model during our research, the defining characteristic is delivery format: recommendations become implementation-ready developer tickets that integrate directly into client Git repositories and Jira workflows, not PDF audit reports.

For B2B tech startups with React, Next.js, or other JavaScript-heavy product architectures, this matters directly. AI crawlers encounter the same technical barriers as traditional search engine crawlers — JavaScript rendering issues, crawl budget waste, restrictive robots.txt — and a site that AI platforms cannot technically access will not be cited regardless of how good the content is. Onely addresses the technical foundation that makes GEO content work.

Industries: B2B SaaS, enterprise, complex headless or JavaScript-heavy architectures

Core Services:

  • Advanced technical SEO (JavaScript SEO, crawlability, AI search readiness, Core Web Vitals)
  • GEO as a standing service line paired with technical implementation
  • Structured data and LLM-readable content architecture
  • Embedded engineering model — deliverables are developer tickets, not audit PDFs
  • Original research into AI citation patterns across ChatGPT, Perplexity, and Google AI Overviews

Client-Fit Profile: Onely works with B2B SaaS companies and enterprise clients where technical complexity is the primary SEO bottleneck. Their model suits companies with development teams capable of executing implementation-ready tickets. The GEO service line pairs directly with technical fixes: when crawlability and indexation blockers are resolved, AI-search content investments compound faster.

Verified Case Study: Onely’s case study library documents enterprise B2B SEO and GEO engagements across complex sites. Enterprise clients have reported 150–250% organic lead volume increases through combined technical and analytics programmes. A specific named, publicly available case study with AI-search citation metrics was not found during our research — Onely’s published documentation focuses on technical depth rather than vertical specificity; ask directly for stage-relevant references.

Pricing: €3,000+/month. Scoped based on the specific technical and GEO work required.

Our Take: Onely is the most technically rigorous agency on this list for B2B tech startups where the bottleneck is not content but architecture. The 5.0★ Clutch rating across 17 reviews and the embedded engineering model are genuine differentiators. They are not the right fit if your site is technically sound and you need content velocity as the primary driver — for that mandate, Discovered Labs or GrowPad are better matches.

Best for: B2B tech startups and SaaS companies with JavaScript-heavy, headless, or technically complex websites needing technical GEO + SEO foundations fixed before content can compound.

Not ideal for: Companies with technically straightforward sites needing rapid content output; startups under €50K/year marketing budget.

7. SEO Monkey — Best for French-Market B2B SaaS and Tech Startups

SEO Monkey - best geo agency for european markets

SEO Monkey is a French generative search optimisation agency combining SEO, GEO, content, and paid search for B2B brands. Founded in 2020 and operating across 400+ projects, the agency combines SEO, SEA (paid search), and GEO into a single integrated digital acquisition programme — a model that is uncommon among specialist agencies and practical for growth-stage tech startups that want one partner managing organic and paid channels alongside AI search visibility.

During our research, SEO Monkey emerged as the strongest French-market option for B2B SaaS and tech companies. Their “Autorité Sémantique et GEO” approach (semantic authority and Generative Engine Optimisation) is deployed through content silos, netlinking campaigns, and GEO citation strategies, measured via Looker Studio dashboards with weekly Loom updates. For French-speaking European tech startups, the combination of French-native content production and documented GEO methodology is a fit that few other agencies on this list can replicate.

Industries: B2B SaaS, professional services, ecommerce, fintech, France

Core Services:

  • SEO (technical, on-page, content silos, netlinking)
  • GEO (Generative Engine Optimisation, citation strategy, AI search visibility)
  • SEA (Google Ads, paid search)
  • Content strategy and production (including blog, case studies, white papers)
  • Data and analytics (Looker Studio dashboards, GA4, weekly Loom reporting)
  • Generative engine optimisation services in Europe for French-speaking SaaS and technology companies

Client-Fit Profile: SEO Monkey works with French B2B companies of all sizes — from tech startups to established professional services companies. Their stated sweet spot is companies wanting to dominate their niche in six months via high-value content strategy. Named clients include B2B SaaS companies, ERP integrators, and professional services firms. The agency is listed on Semrush’s agency partner directory with a 4.7★ rating across 36 reviews and an active review profile.

Verified Case Study — Sillage (B2B SaaS): For Sillage, a signal-based selling B2B SaaS, SEO Monkey built a semantic authority and GEO strategy positioning the brand as the reference source in the “Signal-Based Selling” category. The programme combined full-funnel content deployment (TOFU/MOFU/BOFU), a modern prospecting lexicon, strategic competitor comparisons, and a high-authority netlinking campaign. The engagement is detailed on their case studies page. Specific traffic or citation metrics from this engagement were not made public; ask directly for quantified results when scoping.

Pricing: €3,000+/month. Contact for scope-specific quote.

Our Take: SEO Monkey is the most practical pick for French-speaking B2B SaaS and tech startups that want GEO integrated with SEO and paid search under one agency relationship. The 400+ project track record, native French content capability, data-driven measurement approach, and Semrush-verified 4.7★ rating across 36 reviews make them the clear choice for the French-market brief. The limitation is transparency — specific quantified case study results were not found publicly during our research.

Best for: French-speaking B2B SaaS and tech startups targeting France, Belgium, or Switzerland with integrated SEO, GEO, and SEA.

Not ideal for: English-only mandates; companies needing deep LLM engineering rather than content-led GEO; enterprises with complex multi-market requirements.

How to Choose an SEO and GEO Agency in Europe

Match geographic focus first. GrowPad and Discovered Labs operate in English across all European markets. DREIKON is DACH-only. Peak Ace covers 25+ languages for multi-market mandates. SEO Monkey is the right French-market choice. Onely operates across Europe with a technical-first model.

Ask about AI tracking infrastructure specifically. Request a demonstration, not a landing page, of how the agency measures AI citation frequency. GrowPad uses multi-platform LLM monitoring and documented 75→586 mentions. Omnius has AtomicAGI. Discovered Labs tracks citation rates across five platforms. An agency that shows you a Google rankings dashboard in response to this question is not doing GEO.

Verify the case study matches your vertical. Legal businesses should compare specialist law firm SEO companies, while property technology brands should evaluate SEO and GEO agencies for real estate companies with relevant market experience. A fintech case study tells you little about martech SEO.

Check review recency. A 5.0★ rating with the last review in 2022 is a weaker signal than a 4.9★ with three reviews in the last quarter. GrowPad, Onely, and DREIKON all have active 2025–2026 review activity.

Conclusion

The European SEO and GEO market in 2026 has split into two groups. The first group optimises for Google, adds “GEO” as a service label, and reports on rankings and sessions. The second group has actually built the infrastructure to track AI citations, engineer LLM recommendation patterns, and connect that work to pipeline. The first group is larger. The second group is the one worth your budget.

Agencies providing generative engine optimization services should demonstrate citation tracking, a documented methodology, and case studies with before-and-after AI visibility data. Every agency on this list passed the threshold for the second group: a documented methodology, verifiable case studies with specific AI-search metrics, and a clear ICP that matches European B2B SaaS and tech startups.

For most B2B SaaS and tech companies at seed through Series C, GrowPad is the strongest starting point: 5.0★ Clutch across 38 recent reviews, four 2026 Top badges, a documented 75→586 LLM mentions case study in 90 days, and a pricing floor that works for EU startups. For DACH-market companies wanting certified quality assurance, DREIKON. For French-market startups wanting integrated SEO + GEO + SEA, SEO Monkey. For tech startups with technically broken sites, Onely.

FAQ

What is the difference between SEO and GEO for European tech startups?

SEO (Search Engine Optimisation) focuses on ranking in Google’s traditional blue-link results. GEO (Generative Engine Optimisation) focuses on getting your brand cited and recommended in AI-generated responses from ChatGPT, Perplexity, Gemini, and Google AI Overviews. For B2B SaaS and tech startups in Europe, both matter in 2026. Traditional SEO feeds authority signals that AI platforms draw on; GEO builds the off-site entity presence and citation pattern that influences AI recommendation frequency. The agencies on this list treat them as one system, not two separate retainers.

How long does it take to see GEO results for a European SaaS company?

GrowPad’s logistics software case study showed measurable citation growth within 30 days and 7–8× brand mentions in 90 days. Discovered Labs documented a 3x citation rate improvement in 90 days for a B2B SaaS client. Consistent citation gains are typically visible within 60–90 days of sustained, cluster-focused execution. The speed depends on whether technical blockers (JavaScript rendering, restrictive robots.txt) are present and whether the company already has an SEO foundation that AI platforms can build on.

Should a European startup hire a local agency or work with one serving all of Europe?

It depends on language and market focus. For English-language European B2B SaaS expansion, GrowPad, Omnius, Discovered Labs, and Onely all serve cross-market mandates effectively. For German-speaking markets, DREIKON’s DIN SPEC 33461 credentials and DACH focus make them the specialist choice. For the French market, SEO Monkey is the most practical option. For multi-market campaigns in 25+ languages, Peak Ace is the scale option.

What is LLMO and is it different from GEO?

LLMO (Large Language Model Optimisation) is the practice of building brand citations specifically inside large language models (ChatGPT, Claude, Perplexity) rather than just Google AI Overviews. GEO (Generative Engine Optimisation) is the broader term covering all generative AI search surfaces including AI Overviews. In practice, the best agencies treat them as overlapping: GrowPad runs LLMO and GEO as part of the same citation-building programme. Omnius runs a 22-point GEO process that explicitly covers LLM citation engineering alongside AI Overview visibility.

What starting budget should a European startup expect for SEO + GEO in 2026?

Meaningful European SEO + GEO retainers start at €3,000/month (GrowPad’s EU entry point, Onely, SEO Monkey) and rise to €5,000–€5,500/month for full-service AI-first programmes (Omnius, Discovered Labs, DREIKON, Peak Ace). Budget separately for a standalone AI Search Audit as a first step, GrowPad offers this as an entry-point diagnostic before any retainer commitment. A useful rule of thumb from GrowPad’s 2026 research: companies generating leads from AI search report budgeting €1,000–€5,000/month specifically for LLMO/GEO, separate from traditional SEO spend.

How do I evaluate whether an agency actually does GEO or just claims to?

Ask three questions. First: what is the name of your GEO framework and what are its documented steps? Second: which AI platforms do you track citations on, and with what tooling, can you show me a sample report? Third: can you show a case study where citation frequency improved, with before-and-after data and the prompt sets used to measure it? An agency with a genuine GEO programme answers all three concretely. An agency that rebranded their SEO service will give vague answers about “optimising for AI” without specifics. The agencies on this list that pass all three are GrowPad, Omnius, and Discovered Labs.
