# Best ChatGPT SEO Agencies 2027: The Top UK Agencies for ChatGPT Visibility Ranked

The best ChatGPT SEO agencies in the UK for 2027, ranked on ChatGPT focus, technical and content work, digital PR, AI visibility tracking and revenue impact.

## Key takeaways

- Marketing Signals ranks first among UK ChatGPT SEO agencies for 2027 because it runs ChatGPT and AI search optimisation alongside SEO, digital PR and PPC in one team, with reporting tied to revenue, leads and AI visibility.
- Every agency on this list offers ChatGPT, LLM or AI search visibility as a named service on its own website, and each was judged on ChatGPT focus, technical and content work, third-party mentions, measurement and links to revenue.
- OpenAI says sites that block its OAI-SearchBot crawler will not be shown in ChatGPT search answers, so crawler access is the first thing any agency should check.
- OpenAI says ChatGPT adds utm_source=chatgpt.com to referral URLs, which lets brands track ChatGPT search traffic in their analytics alongside prompt tracking.
- Published prices are rare, with Bigfoot Digital listing AI SEO plans from £500 + VAT a month and Reboot Online saying its GEO pricing starts at £2,500 a month, so compare scope rather than the headline figure.

> **A note on this list:** This ranking is Marketing Signals' own view, and Marketing Signals is one of the agencies in it. Use it as one view alongside independent reviews, case studies and conversations with each agency on your shortlist.

ChatGPT now answers buying questions with live web results. OpenAI says ChatGPT will automatically search the web when a question might benefit from information on the web, and that responses which use search contain inline citations to their sources. When a buyer asks ChatGPT which supplier to use, the brands it names and the pages it links to are the ones that get considered. ChatGPT SEO is the work of making sure your brand is one of them, through a site OpenAI's search crawler can reach, content that answers the questions buyers ask, and mentions on trusted third-party sites that back up what you say about yourself.

This guide ranks the UK agencies we think brands should shortlist for ChatGPT visibility in 2027. We only included agencies that offer ChatGPT, LLM or AI search visibility as a named service on their own website. We judged each one on how specifically it addresses ChatGPT rather than AI in general, the technical work it does on crawler access and site structure, its content and entity work, its ability to earn third-party mentions through digital PR, how it measures visibility in AI answers, and how well that work connects to organic search, leads and revenue. Every competitor was checked against its own website, and the claims we repeat are the ones each agency makes about itself.

Marketing Signals runs [ChatGPT SEO](https://marketingsignals.com/service/ai-search-optimisation/chatgpt-seo) as part of its [AI search optimisation](https://marketingsignals.com/service/ai-search-optimisation) service, which covers visibility in ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews and AI Mode. That work sits in the same team as [organic search](https://marketingsignals.com/service/organic-search), [digital PR](https://marketingsignals.com/service/digital-pr) and [pay per click](https://marketingsignals.com/service/pay-per-click), so the technical fixes, content and third-party coverage that shape how a brand shows up in ChatGPT are planned together rather than bought from separate suppliers. Its published case studies include AI search work for MoneyExpert.

The agency has traded since 2007, has its registered office in Halifax with a fully remote UK team, and works mostly with mid-market and enterprise brands in the UK and the US. Its digital PR team includes a former Reach PLC journalist, which helps brands that need credible third-party coverage to back up what their own site says. Reporting is tied to revenue, leads and AI visibility rather than rankings alone. Marketing Signals is a Google Partner and Microsoft Advertising Partner, is assessed by EcoVadis every year and is an approved supplier to enterprise procurement teams, including Sage.

Rise at Seven is a search and creative agency with offices in Manchester, London and New York. Its AI Visibility and GEO service says it creates category leaders in AI search across ChatGPT, Gemini and Perplexity. The work starts by benchmarking the prompts, AI engines, countries and competitors that matter to a brand, setting a baseline for recommendation frequency, share of voice, brand descriptions, citation sources and sentiment, then diagnosing why the gaps exist.

Where it stands out is the range of channels it uses to close those gaps. Plans can cover technical SEO, onsite content, digital PR, social search, creators, YouTube, Reddit and community, reviews, retailers and international media, and clients can have Rise at Seven deliver the plan or run it in-house. The agency says that ranking on Google does not automatically earn citations and share of voice in LLMs, and it lists consumer brands including Red Bull, JD Sports and Squarespace among its clients.

**Best for:** Consumer brands that want to lead their category in AI answers using PR, social and community activity as well as onsite work.

It also offers ChatGPT consultancy on entity, schema and metadata strategy for teams that want advice rather than delivery.

Its wider LLM SEO work adds llms.txt management, prompt-led keyword research and FAQ content written for AI, and it tracks visibility, sentiment and recommendation frequency across ChatGPT and other LLMs. All of this connects to Everysearch, Found's own approach to search across Google, AI platforms and social. Found lists ISO 27001 certification and partner status with Google, Microsoft and Meta, and runs PPC, paid social, data science and CRO in the same agency.

Its GEO service names ChatGPT, Gemini, Perplexity and Claude, and covers retrieval behaviour analysis of how AI systems reference a brand and its competitors, fan-out query analysis that tests large numbers of prompts, visibility mapping across AI systems, AI readiness audits and reporting that benchmarks AI citation share against competitors.

Delivery runs through GEO content, technical GEO, AI data cleaning and AiPR, its AI-focused digital PR, alongside link building and organic search strategy. Reboot publishes a starting price of £2,500 a month for GEO, reports results including a finance client it says saw LLM referral traffic rise by 194.72%, and has run invite-only GEO roundtables for senior marketers since January 2026.

Beyond on-page and technical SEO it includes preparing sites for AI agents and AI shopping tools, digital PR for brand mentions and automated review generation. Exposure Ninja says most clients begin to see improvements in AI citation frequency within three to six months, and it can add content marketing, CRO, email marketing and PPC.

**Services:** AI search audits and strategy, technical SEO, AI-focused content, AI agent readiness, digital PR and review generation.

Its AI SEO service, which it also calls ChatGPT SEO, LLM optimisation and GEO, optimises for ChatGPT, Perplexity, Google AI Overviews and AI Mode, Gemini and Claude by structuring content, entity signals and authority so AI tools cite the brand in their answers.

The distinctive part is compliance. AI-optimised content is reviewed against UKGC, FCA, ASA and MGA rules, which matters in sectors where an unchecked claim can cause regulatory problems. Monthly reporting covers AI brand mentions and citations, Google AI Overview inclusion and self-reported attribution from customers. The agency says structured data and entity work can show effects within weeks, with broader authority building typically taking three to six months.

The same service also covers Google Gemini, Microsoft Copilot, Perplexity and Claude.

The process runs in five stages, from an AI visibility assessment to ongoing monitoring as models update, with live reporting on AI presence plus documentation and training so in-house teams can maintain the work.

**Best for:** Local and regional businesses that want AI search and ChatGPT visibility on a published monthly price.

## What to Look for in a ChatGPT SEO Agency in 2027

**Crawler access checked first.** OpenAI says OAI-SearchBot is used to surface websites in ChatGPT search, and that sites opted out of it will not be shown in ChatGPT search answers. GPTBot, which OpenAI uses for model training, is a separate crawler. A good agency confirms your robots.txt, firewall and CDN settings let OAI-SearchBot through before it starts on content.

**ChatGPT named in the plan.** Some agencies sell a general AI visibility service. Ask how the plan treats ChatGPT specifically, which buyer prompts it will track, how often it will check them and what it will change when your brand is missing or described wrongly.

**Work beyond your own site.** Most of the agencies on this list treat third-party mentions as part of the job, through digital PR, reviews, Reddit and community activity. Ask what they will do off your site, and avoid anyone selling paid placements dressed up as editorial coverage.

**Measurement you can check.** OpenAI says ChatGPT adds utm_source=chatgpt.com to referral URLs, so ChatGPT search traffic can be tracked in your analytics. Ask for reporting that combines that referral data with prompt tracking and with leads and revenue, rather than a single visibility score.

**Honest timelines.** No agency can promise what ChatGPT will say about you, so be wary of guaranteed placements. The agencies here quote early movement within weeks for technical and structured data work and around three to six months for authority building, which is a fair expectation to set.

## Frequently Asked Questions

**What is ChatGPT SEO?** ChatGPT SEO is the work of making a brand more likely to be mentioned, cited and linked when people ask ChatGPT about the products or services it sells. It combines technical access for OpenAI's search crawler, content that answers buyer questions clearly, entity and structured data work, and earning mentions on trusted third-party sites. It overlaps heavily with good SEO and digital PR, and agencies usually sell it as part of AI search optimisation or GEO.

**How does ChatGPT decide which websites to show?** OpenAI does not publish a full ranking method. Its help pages say ChatGPT searches the web automatically when a question might benefit from it, that answers using search include inline citations, and that it may share disassociated search queries with third-party search providers such as Bing. OpenAI also says any public website can appear in ChatGPT search as long as it does not block OAI-SearchBot, and it refers to signals that a page is relevant to the user's query.

**Do I need to change my robots.txt for ChatGPT?** You should check it. OpenAI says OAI-SearchBot is used to surface websites in ChatGPT search, and that sites which opt out of it will not be shown in ChatGPT search answers, although they can still appear as navigational links. GPTBot is a separate crawler used for model training, so you can block training and still allow search. OpenAI says robots.txt changes take around 24 hours to take effect in its systems.

**How do I measure traffic from ChatGPT?** OpenAI says ChatGPT adds utm_source=chatgpt.com to referral URLs, so sites that allow OAI-SearchBot can see ChatGPT referral traffic in tools such as Google Analytics. That shows clicks, not mentions, so most agencies pair it with prompt tracking that records how often a brand is named, cited and described across a set of buyer questions. The measure that matters most is whether that visibility turns into leads and revenue.

**How long does ChatGPT SEO take to work?** It depends on your starting point and your competition. Absolute Digital Media says structured data and entity work can show effects within weeks, Ink Digital says most brands see improvements within 6 to 12 weeks, and Exposure Ninja and Absolute Digital Media both put broader gains at three to six months. Crawler fixes register fastest, as OpenAI says robots.txt changes take around 24 hours, while third-party authority takes longest to build.

**How much does a ChatGPT SEO agency cost in the UK?** Few agencies publish prices. Bigfoot Digital lists AI SEO plans at £500 + VAT a month and from £1,000 + VAT a month, and Reboot Online says its GEO pricing starts at £2,500 a month. Cost is driven by the number of prompts and markets tracked, the content and technical work needed, and whether digital PR is included. Marketing Signals runs [AI search optimisation](https://marketingsignals.com/service/ai-search-optimisation) alongside SEO and digital PR, with reporting tied to revenue, leads and AI visibility.
