UK GEO Agencies 2026: 12 Providers Compared

Content updated: 2 October 2026. Provider-source research: 10 September 2026.

This guide compares 12 UK GEO providers for 2026 using their published services, case studies, methodology and pricing. Commercial disclosure: I own Sunny Patel SEO and benefit if readers hire my practice. Its listing is an owned-service profile, shown first and labelled separately; that placement is not an independent ranking. No other provider paid for inclusion, and I have no commercial relationship with the other providers listed. The review is not an exhaustive market survey or a controlled comparison of results.

GEO (Generative Engine Optimisation) is the practice of getting a brand cited across generative AI systems: Google AI Overviews, ChatGPT, Perplexity, and Copilot. Published service descriptions and measured AI outcomes are different evidence. This guide identifies the evidence described for each provider without assuming that an unpublished result does not exist. It is the GEO sibling to my best AEO agencies review, and the next section explains how the two terms differ.

Directory inclusion: providers with a published GEO or AI-search offer, public methodology or work examples, and service information useful to UK buyers. The review records whether AI-specific evidence is published; a citation or conversion was not a requirement that every listed provider met. These are inclusion checks, not competitive scoring criteria.

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.

GEO, AEO and SEO can share technical, editorial and entity work, but an improvement in one channel does not establish a result in another. For Google AI Overviews and AI Mode, Google says existing SEO practices remain relevant: pages must be indexed and eligible for a Search snippet, and no special AI schema is required. That is eligibility guidance for Google, not a description of how every assistant selects citations. Ask a GEO provider which platforms it tests and which outcomes its work has actually produced.

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.

Similarweb reported 357% year-on-year growth in AI referral traffic to the top 1,000 websites in June 2025. That is a sampled referral trend, not proof of lost traffic caused by the absence of a brand citation. Seer separately observed lower organic CTR in its tracked AI Overview query cohort from June 2024 to September 2025; those comparisons do not isolate causation. The AI search statistics page distinguishes the populations, dates and outcomes.

External providers by published service focus

The table below groups the 11 external providers by their published services and work examples. It is a starting point for enquiries, not a performance ranking; a revenue or SEO case is not automatically an AI-citation result. My owned practice is disclosed separately below and included in the 12-provider directory overview. Confirm the proposed team, relevant evidence and current fee directly with each provider.

Quick Comparison at a Glance

Sunny Patel SEO: Owned Practice, Documented Inbound Enquiry

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

Commercial disclosure: I own this practice and receive revenue from its services. Its first position is promotional placement, not a neutral ranking or proof of superiority over other providers.

In April 2026, Express Medicals sent an inbound enquiry after discovering my practice through a Bing Copilot citation. The enquiry did not become a paid engagement. It is a documented discovery example for my AI search optimisation work, not a client-conversion result.

My semantic SEO work covers entity information, topical coverage and understandable content. GEO and AEO tasks are included in my engagements rather than sold as an upsell. The April 2026 Express Medicals record documents one inbound enquiry after a Bing Copilot citation; it does not isolate which task caused the citation or prove that SEO gains produce GEO gains. I work with SMEs, B2B, SaaS, professional services and healthcare firms, with in-person meetings across London, the Thames Valley and the South East.

Documented own case: The April 2026 Express Medicals inbound enquiry after a Bing Copilot citation, alongside my published semantic SEO methodology. This case does not establish unique capability or comparative market leadership.

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: Service Focus - Earned Citations Through Digital PR

Based in: Sheffield, with London and US offices | Service fit: Consumer brands commissioning digital PR | Budget: £3,000-6,000/mo

Rise at Seven publishes creative, data-led digital PR work aimed at earning press coverage. That service can suit a consumer brand whose brief includes original research and earned media. Press coverage and AI URL citations are different outcomes: ask for captured AI answers and a repeated measurement method before treating the PR portfolio as evidence of GEO performance.

Published services and evidence: Creative, data-led digital PR for brands seeking earned media. Request separate AI-citation evidence; the PR offer does not establish a generative-engine outcome.

Considerations:

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

Reboot Online: Service Focus - Research-Led AI Search Experiments

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

Reboot Online publishes controlled search experiments and research-led methodology. Those publications provide work for a buyer to inspect; this directory has not established that the practice is rare or that its content causes AI citations through entity authority. Ask which experiment applies to your target platform, what was tested and whether the proposed work follows from the result.

Published services and evidence: Published search experiments and research-led methodology; ask which findings have been tested in the AI platforms relevant to your brief.

Considerations:

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

Aira: Service Focus - Brand Corroboration Through Digital PR

Based in: Northampton | Service fit: Mid-market entity authority | Budget: Mid-market retainers

Aira publishes research-backed digital PR services and methodology reports, including analysis of campaigns that underperformed. For a mid-market company, that portfolio is evidence to inspect for a PR brief. Earned links and brand mentions do not by themselves prove an assistant will cite the brand; request AI-specific observations for your target platforms and questions.

Published services and evidence: Research-backed digital PR and published campaign analysis, including reports of underperforming campaigns.

Considerations:

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

Builtvisible: Service Focus - Extractable Editorial Content

Based in: London | Service fit: Medium to large brands | Budget: Mid-large retainers

Builtvisible publishes content-led SEO, editorial production and original data journalism for medium-to-large brands, alongside technical SEO work. Those services may fit a substantial content programme. This review has not measured whether its content format earns more AI citations; ask for relevant captured answers and the proposed delivery team.

Published services and evidence: Content-led SEO, editorial production and data journalism for medium-to-large brands. This service description does not establish an AI-citation result.

Considerations:

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

Distinctly: Service Focus - B2B and SaaS AI Search

Based in: Hertfordshire | Service fit: B2B, SaaS, professional services | Budget: Mid-market retainers

Distinctly publishes B2B SEO and content services for technology and professional-services companies. That is a service-fit consideration for a research-intensive buyer journey, not proof that its topical depth is rewarded by AI systems. Ask how the agency tests relevant buyer questions and distinguishes citations from referral or lead outcomes.

Published services and evidence: B2B and professional-services SEO with a focus on content coverage. Request separate evidence for the AI platforms and questions you want to target.

Considerations:

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

Impression Digital: Service Focus - Integrated SEO, PR, and GEO

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

Impression Digital publishes SEO, PPC, digital PR, analytics and AI-search services within an integrated marketing offer. For a combined brief, ask which teams will deliver each workstream and which AI-search outcomes the provider can document.

Published services and evidence: SEO, PPC, digital PR and analytics within an integrated marketing offer.

Considerations:

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

Semetrical: Service Focus - Entity-Led GEO and AI Visibility Audits

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

Semetrical publishes a Generative Engine Optimisation service covering AI-visibility auditing, content engineering for LLM retrieval, and knowledge/entity optimisation. Its service page describes making a brand discoverable, accurately represented and measurable across generative search environments. Those are the agency's stated aims; ask for evidence of the outcomes relevant to your brief.

Published services and evidence: A published GEO service describing AI-visibility auditing, content engineering and knowledge/entity optimisation.

Considerations:

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

Screaming Frog: Service Focus - Technical AI Search Testing on a Day Rate

Based in: Henley-on-Thames, Oxfordshire | Service fit: 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.

Published services and evidence: An AI-search service describing bot analysis, prompt tracking, sentiment analysis and technical testing on a project day-rate basis.

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: Service Focus - Multi-Sector GEO with Published AI Overview Results

Based in: London | Service fit: 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).

Published services and evidence: A published Shoosmiths case reporting 15 featured snippets and 21 AI Overviews, alongside cases in education, healthcare-adjacent work and professional services. These are agency-reported outcomes.

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: Service Focus - SME and E-commerce GEO

Based in: Altrincham, Manchester | Service fit: 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.

Published services and evidence: An e-commerce case-study portfolio for online retailers assessing a wider SEO or PPC programme. This is not a measured comparison of AI performance.

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: Service Focus - B2B and SaaS GEO

Based in: Nottingham, with a London office | Service fit: 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), providing published examples for a B2B buyer to inspect; it does not establish comparative GEO performance.

Published services and evidence: An AI Search service and a published Infodesk SaaS case reporting lead growth after a wider rebrand and marketing programme. The case does not isolate a GEO contribution.

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

For a London GEO-agency shortlist, this comparison lists Semetrical, Reboot Online, Builtvisible and Passion Digital with London offices; Rise at Seven lists Sheffield and London, and Impression Digital and Hallam list Nottingham and London. Sunny Patel SEO is based in Reading and offers London meetings, so it is a nearby consultant option rather than a London office. These are location facts from the September 2026 source review, not evidence of better results. Confirm the assigned team and meeting arrangements before hiring; the providers below also describe remote UK delivery.

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.

Published sector examples

Healthcare and medical

My owned practice, Sunny Patel SEO, received an April 2026 inbound enquiry from Express Medicals after a Bing Copilot citation of this site; it did not become a paid engagement. Passion Digital separately publishes healthcare-adjacent work, including a cosmetic surgery clinic case reporting a 545% increase in organic traffic and a website project for NHS Kingston Hospital Charity. Those agency-reported cases are not a controlled comparison of AI-search performance.

Education

Passion Digital publishes education case studies for King's College London, EIT Campus and Cambridge Dictionary, plus a Science Museum project. Those examples provide a starting point for an education-sector enquiry; this review does not establish that other providers lack comparable experience.

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 publishes e-commerce case studies with revenue and ROAS figures. Consider that portfolio if your GEO requirement sits within a wider e-commerce SEO or PPC programme; those outcomes are not an AI-specific comparison with the other providers.

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.

Compare GEO proposals by the work included, implementation responsibility, reporting and total commitment. A separate GEO fee is not evidence of poor quality, and inclusion in an SEO retainer does not prove AI-search results. Ask what the additional work delivers and how the provider will measure the outcome.

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

To compare GEO providers, request a repeatable record for the platforms and buyer questions that matter to your business. A dated screenshot can show one appearance; it cannot establish persistent visibility or prove the provider caused it. Record the prompt, platform/mode, market and date, then distinguish a linked URL citation, brand mention, referral session and qualified enquiry. This guide has not run that controlled comparison across the agencies listed.

1. Evidence for the promised outcome. For citation work, ask for the cited URL and captured answer. For lead generation, ask how a recorded enquiry was attributed and qualified. A brand name in an answer is a mention unless a supporting URL is linked.
2. Entity authority capability. Understanding of how LLMs identify and trust entities. See what is entity SEO.
3. Technical and content eligibility. Ask how the provider checks crawl access, indexation, snippet controls and factual content. Structured data should match the visible page; Google does not require special AI markup.
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. "What work does the GEO fee cover?" Compare the scope, implementation and measurement whether GEO is a separate project or part of an SEO retainer. Ask for evidence matching the promised outcome.
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 this comparison was assembled

The September 2026 research reviewed four types of published information. No standardised performance score or controlled provider comparison was run:

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 enquiry evidence, disclosed separately: the April 2026 Express Medicals inbound enquiry after a Bing Copilot citation. The enquiry did not become a paid engagement. It supports the discovery example in the owned-service profile, not a claim that competitors lack enquiries.
4. Pricing transparency, noting plainly where a figure is published and where it is not, rather than presenting an estimate as fact.

The original September research checked the cited service pages and case studies directly; they were not all rechecked for this October disclosure correction. 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.

Provider-source review: 10 September 2026. Disclosure and comparison limits corrected: 2 October 2026.
