Top GEO Agencies UK 2026

This is a list of the top GEO agencies in the UK for 2026, ranked by demonstrated generative-engine results rather than marketing claims. As an independent SEO consultant based in Reading, Berkshire, I have no financial relationship with any provider listed here, and no company paid for inclusion. I am listed first myself, transparently, because I am the only provider on this list with a documented AI-search lead conversion, and excluding the author of a GEO list would be less honest than disclosing the conflict openly.

GEO (Generative Engine Optimisation) is the practice of getting a brand cited across generative AI systems: Google AI Overviews, ChatGPT, Perplexity, and Copilot. It is the fastest-growing specialism in UK search, and the one with the widest gap between claims and evidence. Most agencies added "AI" to a services page in 2025, yet very few can show a single real citation in a generative engine, let alone a lead that came from one. This list separates the two. It is the GEO sibling to my best AEO agencies review, and the next section explains how the two terms differ.

Selection criteria: documented AI-search citations or conversions, entity authority and structured-data capability, published methodology, and fit across different business types and budgets.

What is GEO (and how it differs from AEO and SEO)

GEO (Generative Engine Optimisation) is the practice of earning citations across generative AI systems, including Google AI Overviews, ChatGPT, Perplexity, and Copilot. The goal is to be the source a generative engine names when it composes an answer. AEO (Answer Engine Optimisation) is the narrower version focused on direct answers from assistants and answer engines. SEO earns traditional blue-link rankings.

The three overlap heavily. Strong semantic SEO and entity authority feed all of them, because large language models select sources the same way a careful researcher would: they favour content that is comprehensive, well-structured, corroborated, and unambiguous about its author. A genuine GEO specialist optimises for extraction and citation, not just position. AI Overviews are the clearest example, sitting inside Google itself and pulling from sources the model trusts.

For the underlying mechanics, see what is LLM optimisation and how to optimise content for AI search.

Whether you call them GEO companies, GEO SEO agencies, or a generative engine optimisation agency, the same evidence bar applies: a documented citation, over a services page claim.

According to Similarweb, AI referral traffic to the top 1,000 websites grew 357% year-over-year to June 2025, moving visibility from ten blue links toward a handful of cited sources. Google AI Overviews reduce organic clicks for brands they do not cite, so the cost of being absent from a generative answer is now measured in lost traffic. The full dataset sits in the AI search statistics breakdown.

Quick Comparison at a Glance

Sunny Patel SEO: Best for Documented GEO Results

Based in: Reading, Berkshire, serving London, the Thames Valley, and the South East in person plus UK-wide remote | Best for: SMEs, B2B, SaaS, healthcare, AI search visibility | Budget: From £1,200/mo

Disclosure: This is my own practice. I list myself first because I am the only provider here with a documented AI-search conversion, and hiding that would be less honest than disclosing it. Evaluate the evidence and decide for yourself.

I am the only consultant on this list with a verified AI search optimisation lead conversion. A London-based healthcare client, Express Medicals, discovered my services because Bing Copilot cited my content, then converted to a paid engagement. That is GEO working in practice: a citation that produced a client, not a slide about AI in a pitch deck.

The method underneath it is semantic SEO: building topical authority through entity relationships, comprehensive coverage, and structured content that generative engines can extract cleanly. GEO and AEO are integrated into every engagement from day one rather than sold as an upsell, because generative-engine visibility comes from the same entity and content foundations as strong organic rankings. This suits SMEs, B2B, SaaS, professional services, and healthcare firms, particularly in regulated or YMYL niches where source credibility decides whether a generative engine cites you. Reading is 25 minutes from London Paddington, with in-person meetings available across London, the Thames Valley, and the South East.

Unique strength: A documented AI-search lead conversion plus semantic SEO methodology, the only UK consultant combining the two with receipts.

Considerations:

• Sole practitioner, so execution capacity for very large content volumes is limited
• Not suited to businesses wanting one provider to manage every digital channel

Starting from: £1,200/month. Start with an AI Visibility Audit if you want a baseline of current citations and named competitors before committing to ongoing work.

Rise at Seven: Best for Earned Citations Through Digital PR

Based in: Sheffield, with London and US offices | Best for: Consumer brands earning AI-weighted mentions | Budget: £3,000-6,000/mo

Rise at Seven built their reputation on creative, data-led digital PR engineered to earn national press coverage. That matters for GEO because large language models weight sources that are widely mentioned and corroborated, so the high-authority citations a strong PR campaign earns are exactly the signals that get a consumer brand named in a generative answer.

Unique strength: A creative team that genuinely understands journalism and search, earning the corroborating citations GEO depends on without paid placements.

Considerations:

• Campaign-led model requires budget and client involvement
• Less focused on on-page structured data and extraction than methodology-first specialists

Reboot Online: Best for Research-Led AI Search Experiments

Based in: London | Best for: Evidence-based GEO in competitive markets | Budget: From £2,000/mo

Reboot Online runs controlled experiments and publishes the results, a rare practice that suits businesses valuing tested methodology over thought-leadership marketing. That experimental culture is well suited to testing how AI engines rank, parse, and cite content, and their statistics-driven content earns the links and mentions that feed entity authority.

Unique strength: Real experimentation rather than recycled advice, the right mindset for a field that changes monthly.

Considerations:

• Research-heavy approach rewards patience and longer engagements
• Less of an SME-priced option

Aira: Best for Brand Corroboration Through Digital PR

Based in: Northampton | Best for: Mid-market entity authority | Budget: Mid-market retainers

Aira specialises in research-backed digital PR and publishes transparent reports on its own methodology, including honest analysis of campaigns that underperformed. For mid-market companies, their value is corroboration: earned links and brand mentions across authoritative publications convince a generative engine that a brand is a credible entity worth citing.

Unique strength: A genuinely data-driven culture that publishes its own failures, a strong signal of substance over spin.

Considerations:

• Success depends partly on media climate and newsworthiness
• Less focus on semantic content architecture than methodology-first specialists

Builtvisible: Best for Extractable Editorial Content

Based in: London | Best for: Medium to large brands | Budget: Mid-large retainers

Builtvisible produces content-led SEO with strong editorial standards and original data journalism, best suited to medium-to-large brands where premium content is the primary growth lever. Comprehensive, well-structured, citable content is precisely what generative systems extract from, and their technical capability covers the structured data feeding a sound technical SEO audit foundation.

Unique strength: Editorial quality high enough to earn citations through merit rather than outreach volume.

Considerations:

• Minimum engagement sizes reflect a mid-to-large target market
• Content-led timelines require patience to demonstrate ROI

Distinctly: Best for B2B and SaaS AI Search

Based in: Hertfordshire | Best for: B2B, SaaS, professional services | Budget: Mid-market retainers

Distinctly specialises in B2B SEO for technology and professional-services companies whose buyers research with AI assistants across long, research-intensive purchase journeys. Their strength in deep topical coverage maps directly to those research-stage prompts, the queries where being the cited source compounds over months of evaluation.

Unique strength: Genuine B2B specialism with the topical depth that AI research queries reward.

Considerations:

• Less suited to consumer or high-volume e-commerce
• Smaller team limits very large content programmes

Impression Digital: Best for Integrated SEO, PR, and GEO

Based in: Nottingham, with London office | Best for: Mid-market integrated programmes | Budget: Mid-market retainers

Impression Digital delivers integrated SEO, PPC, digital PR, and analytics with genuine SEO depth, and is building generative-engine readiness into that mix. For mid-market brands wanting organic, paid, and AI-search visibility coordinated under one roof, the integrated model has real advantages as generative and traditional search converge.

Unique strength: Strong SEO capability inside a full-service model, uncommon since most full-service agencies treat SEO as an afterthought.

Considerations:

• You pay for breadth you may not fully use
• GEO is one capability among many rather than the core specialism

Semetrical: Best for Entity-Led GEO and AI Visibility Audits

Based in: London | Best for: Brands needing a dedicated AI-visibility audit and entity/knowledge-graph optimisation | Budget: Not published

Semetrical runs a dedicated Generative Engine Optimisation service built around three planks: AI visibility auditing, content engineering for LLM retrieval, and knowledge and entity optimisation. The agency's own framing, "ensuring your brand is discoverable, accurately represented, and measurable across generative search environments," matches the technical, entity-first definition of GEO used throughout this page rather than a repositioned content-marketing offer.

Unique strength: A GEO service built around auditing and entity work first, useful for a brand that wants to know where it stands with generative engines before committing to a content programme.

Considerations:

• No published case studies specific to the GEO service at the time of writing
• No pricing published; enquire directly

Screaming Frog: Best for Technical AI Search Testing on a Day Rate

Based in: Henley-on-Thames, Oxfordshire | Best for: Businesses wanting technical AI-bot analysis and prompt tracking without a fixed monthly retainer | Budget: Day rate, scope agreed per project

Screaming Frog is best known worldwide for its SEO Spider crawler, and its agency side now runs a dedicated AI search optimisation offer covering AI bot analysis, prompt tracking, sentiment analysis, content strategy, and testing against ChatGPT, Gemini, Perplexity, and Google AI Mode. Pricing is structured as a day rate, with the number of days agreed per project rather than a published monthly fee, which suits a business that wants defined technical work rather than an open-ended retainer.

Unique strength: Deep technical crawling and testing pedigree applied directly to how AI bots read a site, a genuinely technical entry point into GEO.

Considerations:

• Day-rate model means no published monthly figure to compare directly against retainer-based competitors
• Case studies on the AI search page are limited to client quotes rather than measured results

Passion Digital: Best for Multi-Sector GEO with Published AI Overview Results

Based in: London | Best for: Education, professional services, and mid-market brands wanting a full AI Search offer | Budget: Not published

Passion Digital runs a GEO and AI Search service covering AIO optimisation, LLM performance tracking, deep research, and entity optimisation, and backs it with case studies naming actual AI Overview results: the agency reports securing "15 Featured Snippets & 21 AI Overviews" for law firm Shoosmiths. Its published case studies also cover education (King's College London, EIT Campus, Cambridge Dictionary), healthcare-adjacent work (a cosmetic surgery clinic, up 545% organic traffic, and an NHS charity site), and professional services (Knight Frank, Moore Kingston Smith).

Unique strength: One of the few agencies on this list with a published AI Overview citation count attached to a named client, rather than a generic claim of AI-search capability.

Considerations:

• No pricing published; broad case-study spread across sectors means depth in any one sector varies by team assigned
• Larger agency structure than the specialist boutiques on this list

Add People: Best for SME and E-commerce GEO

Based in: Altrincham, Manchester | Best for: SMEs and e-commerce brands wanting GEO alongside an existing SEO or PPC programme | Budget: Custom quote; no published pricing

Add People offers a dedicated Generative Engine Optimisation service alongside a large existing e-commerce and SME client base, positioned as helping businesses "become recommended by ChatGPT and other AI assistants" through entity optimisation, GEO-focused content, review strategy, and technical audits for AI compatibility. The agency's own pricing page states pricing "depends on your business goals," worked out per client rather than published as a rate card.

Unique strength: The largest e-commerce case-study portfolio of any agency on this list, useful evidence for online retailers weighing GEO against a plain SEO or PPC retainer.

Considerations:

• The featured case study on the GEO service page itself (Hurley Burley) currently displays placeholder 0% metrics rather than live results; ask for a current example directly
• GEO sits inside a broader SEO/PPC offer rather than as a standalone specialism

Hallam: Best for B2B and SaaS GEO

Based in: Nottingham, with a London office | Best for: B2B and SaaS companies | Budget: Not published

Hallam runs an "AI Search" service inside its Reach practice, and its case studies include a genuine SaaS rebrand result: Infodesk, a B2B software company, reported 58 times year-on-year growth in marketing-qualified leads following the engagement. That result sits alongside other B2B work (DataIQ, Aberdeen, Open GI), giving the agency a stronger B2B evidence base than most GEO-specific pages on this list.

Unique strength: A measured SaaS lead-generation result (Infodesk) tied to the same team running the AI Search offer, rather than AI-search claims sitting apart from the case studies.

Considerations:

• The Infodesk result is attributed to a broader rebrand and marketing programme, not isolated to GEO activity alone
• No pricing published

GEO agencies by UK region

Every agency on this list delivers remotely UK-wide regardless of office location; use the table below to find an in-person option nearby.

I checked for a genuine GEO agency office in Exeter, Leicester, and Edinburgh while researching this list and could not verify one among the candidates reviewed. Several sites publish templated "GEO agency" landing pages for individual UK towns, including those three, without a checkable local address or team behind them, so none are listed here. Every agency above serves the South West, the East Midlands, and Scotland remotely; say so at enquiry stage if an in-person meeting in one of those areas matters to you.

Best GEO agency by sector

Healthcare and medical

Sunny Patel SEO is the only provider on this list with a documented AI-search conversion in healthcare: Express Medicals, a London clinic, became a client after discovering Sunny Patel SEO through a Bing Copilot citation of this site's content. Passion Digital has published healthcare-adjacent work too, including a cosmetic surgery clinic case study reporting a 545% increase in organic traffic and a website project for NHS Kingston Hospital Charity, worth a look if you need a larger team than a sole practitioner.

Education

Passion Digital has the strongest published education evidence on this list, with case studies for King's College London, EIT Campus, and Cambridge Dictionary, plus a Science Museum project. None of the other agencies reviewed here publish education-specific case studies at the time of writing.

B2B SaaS

Distinctly specialises specifically in B2B and SaaS content mapped to research-stage AI queries. Hallam is a second option with a directly measured SaaS result: a 58 times year-on-year increase in marketing-qualified leads for software company Infodesk, following a rebrand and marketing programme.

E-commerce

Add People has by far the largest e-commerce case-study portfolio of any agency reviewed here, spanning dozens of online retailers with published revenue and ROAS figures. If your GEO need sits inside a wider e-commerce SEO or PPC programme rather than as a standalone specialism, this is the strongest fit.

Professional services

Passion Digital's professional-services case studies include Knight Frank, Moore Kingston Smith, and law firm Shoosmiths, the last of which the agency reports secured 15 featured snippets and 21 AI Overviews: a rare instance of a named AI Overview count attached to a specific client among the sites reviewed for this list.

GEO agency pricing in the UK (2026)

Most agencies on this list do not publish a GEO rate card; pricing is quoted per client, or delivered inside a wider SEO retainer. The bands below reflect the general UK market for GEO-inclusive SEO work, with published figures marked as such.

Be cautious of a provider charging an enterprise rate for "GEO" as a bolt-on with no documented AI citations attached. Genuine GEO companies build it into the same content and entity strategy as the rest of the retainer, rather than pricing it as a separate premium line item.

Hiring a GEO specialist vs a GEO agency

A GEO specialist, typically a sole consultant or a two-to-three-person team, works directly on your account, understands your entity and content set in detail, and usually costs less than a full agency retainer. The trade-off is capacity: a specialist cannot run a large content programme or a big digital PR campaign alongside GEO work. Sunny Patel SEO on this list is a specialist example, and says so plainly in its own considerations.

A GEO agency, from a boutique like Semetrical or Screaming Frog through to a full-service shop like Rise at Seven or Impression Digital, brings more people and more channels: content teams, digital PR, technical SEO, and in some cases paid media, all under one contract. That suits a brand that wants generative-engine work coordinated alongside a bigger organic or paid programme, and can absorb the higher retainer that comes with it.

Neither model is inherently better. Ask any provider, specialist or agency, for a documented AI citation before signing; capacity and price differ, but the evidence bar for genuine GEO capability should not.

How to Choose a GEO Agency

Most providers advertising "GEO" cannot demonstrate a single citation. These markers separate genuine generative-engine capability from a repositioned services page:

1. A documented citation or conversion. A screenshot of the brand named in an AI Overview, ChatGPT, Perplexity, or Copilot, ideally with a lead attached.
2. Entity authority capability. Understanding of how LLMs identify and trust entities. See what is entity SEO.
3. Structured-data fluency. The markup that helps AI crawlers extract a page accurately.
4. A measurement method. How they track citations and generative-engine visibility over time, not just rankings.
5. Published methodology, not slogans. Evidence of how they work, weighted above testimonials.

If your brand is missing from generative answers, start with why your brand is not appearing in ChatGPT, then build the foundation with how to build topical authority. The discipline that applies to any SEO hire is set out in how to choose an SEO consultant.

Questions to Ask Any GEO Provider

1. "Show me a brand you have made appear in a generative answer." A screenshot from an AI Overview, ChatGPT, Perplexity, or Copilot. No example means no proof.
2. "How do you build and measure entity authority?" A real answer references corroboration, structured data, and citation tracking, not just "we optimise for AI".
3. "Is GEO a separate add-on or built into the strategy?" Genuine GEO comes from the same content and entity foundations as good SEO; a premium standalone "AI" line item with no results is a red flag.
4. "What changed in your method over the last six months?" Generative search moves fast. A provider who cannot answer is not keeping up.
5. "What do I own if we stop after three months?" You should keep all strategy, audits, and content.

How we ranked these GEO agencies

This list was built from four checks, in order of weight:

1. A genuine GEO or AI search service page, naming Generative Engine Optimisation, AI search, or the specific generative engines (AI Overviews, ChatGPT, Perplexity, Copilot) explicitly, rather than an "AI" mention buried in a broader SEO page.
2. Published case studies or client evidence, checked directly on the agency's own site, favouring any result tied specifically to an AI Overview, citation, or generative-engine outcome over a generic traffic or ranking number.
3. My own AI-citation evidence, where I have it: the Express Medicals conversion via Bing Copilot is the only documented AI-search lead conversion among the providers listed.
4. Pricing transparency, noting plainly where a figure is published and where it is not, rather than presenting an estimate as fact.

Every service page and case study cited on this page was checked directly during this update. Several sites claiming "GEO agency" services for individual UK towns, including some appearing prominently in search results for Edinburgh, Exeter, and Leicester, were checked and excluded because they could not be verified as a real local team or office at the time of writing.
