Answer-first summary

When people ask AI assistants where to find private cancer care in the North West, Clatterbridge Private Clinic is now among the clinics that come back. That didn’t come from a GEO project launched last year. It rests on eight years of work Castle has done with the clinic since 2018: the brand, the website, a large and growing library of medically reviewed content, articles written with the clinic’s consultants, regional press and advertising, and a consistent record of the clinic stating clearly what it treats, where, and who treats it.

Clatterbridge Private Clinic is the private patient service of The Clatterbridge Cancer Centre NHS Foundation Trust, with sites in Liverpool and Wirral. Its consultants are specialists who also treat NHS patients within the Trust, and many are active in research and clinical trials. The expertise was always there. Our job has been to make it visible, first to patients and referrers, then to Google, and more recently to the AI systems that now sit between a patient’s question and the clinic’s website.

The things that made the clinic visible in traditional search turned out to be much of what AI search draws on: specialist content written with and reviewed by consultants, joined-up coverage of specific cancers and treatments, a consistent brand, and references to the clinic on sites it doesn’t control. Since 2025 we have been adapting that work deliberately for AI search. This case study explains what that involved, what we can show so far, and what we can’t show yet.

Why this is a GEO case study

Healthcare is the sector where AI search has least room for error. A question about cancer treatment has serious consequences for the person asking it. The sources an AI system relies on to answer need to be ones it has reason to trust: identifiable specialists, clinically reviewed information, and organisations that other credible sources describe in the same way. A clinic can’t switch those things on. It either has them and has published them clearly, or it hasn’t.

This is a long-term project. Most of what makes Clatterbridge Private Clinic a plausible source for an AI answer was built for other reasons: to help patients understand their options, to give referrers confidence, and to rank in Google for specific cancers and treatments. The GEO work that followed was about making that material easier for AI systems to find, interpret and quote accurately.

We think that is the honest description of GEO in a regulated sector. The technical and structural work matters, and the sections below explain it. But it works on top of authority that already exists. It doesn’t create it.

About Clatterbridge Private Clinic

Clatterbridge Private Clinic opened in 2013 as the private patient service of The Clatterbridge Cancer Centre NHS Foundation Trust. It treats patients at sites in Liverpool and Wirral, and income from private care is reinvested in the Trust’s NHS services.

The clinic treats a wide range of cancers, from breast, prostate and lung to haematological and eye cancers. Treatments include chemotherapy, immunotherapy and targeted drug therapies, several forms of radiotherapy, and proton beam therapy for eye cancer. Its consultants also work within the NHS Trust, and many lead research and clinical trials in their fields.

Patients arrive by several routes. Some have private medical insurance. Some are self-funding, often after an NHS diagnosis. Others come through a GP or consultant referral, or through the clinic’s partnership on the Isle of Man. Each of those groups has different questions, and that shaped a good deal of the content strategy described below.

The brief

Clatterbridge Private Clinic initially came to Castle in 2018 as they wanted a full-service marketing partner to help them with all aspects of their marketing. Primarily, they were looking for a rebrand and a new website to position themselves as a trusted brand within the private medical sector. The scope has widened steadily since then to cover almost all of the clinic’s marketing, but the underlying problem hasn’t changed much.

Choosing where to have cancer treatment is about as consequential as a decision gets, and it is usually made under pressure, often within days of a diagnosis. The patient, or more often a partner or adult child doing the research, needs to understand a lot quickly. They need to know what the clinic offers, whether it treats this cancer, who they would see, how private treatment fits alongside NHS care and how it is paid for. And they need to trust the source before any of that will be believed.

The clinic also has two audiences with different needs. Patients want clear, calm explanations. Referring consultants, GPs, insurers and partner organisations want confidence in the clinical service and practical detail about pathways. Content written for one group often doesn’t work for the other.

Then there’s the name. “Clatterbridge” is used by the NHS cancer centre, by the Wirral health park where the centre began, and by a separate Clatterbridge Hospital on the same site. The link to the NHS Trust is one of the clinic’s strongest assets. It also means search engines and AI systems have to tell apart several organisations with overlapping names, and a patient looking for the private service can easily end up on an NHS page.

Geography mattered too. The clinic wanted to reach suitable patients well beyond Merseyside, in a market where national private hospital groups have much larger footprints.

And cancer treatment changes quickly. New drugs are licensed, trials open and close, and guidance is revised. Whatever the clinic publishes has to be clinically accurate when it goes live and stay accurate afterwards. That rules out most of the high-volume content tactics used in less sensitive sectors.

The foundations

Brand and website

Castle designed the Clatterbridge Private Clinic logo, branding and delivered a new, fully-optimised site. The aim was a brand that looked like what the clinic is: a specialist clinical service connected to a major NHS cancer centre. It also had to hold together everywhere it would appear, from the website and a printed treatment brochure to an airport gate screen and the side of a bus on the Isle of Man.

We then designed and built the website, and we have written and developed it ever since. It is organised around the questions patients bring. Which cancer do I have? What treatments are available? Who would treat me? How do I pay, and how do I get in touch?

Cancer types, treatments and consultants each have their own pages, and those pages link to one another. A consultant’s profile sets out their specialities and special interests and connects back to the conditions they treat. Most profiles also carry the consultant’s GMC number. As the clinic has added treatments, consultants and services, the site has grown with it, and new pages slot into that structure.

The site was built to be accessible for all, including those with disabilities, in line with WCAG 2.1 AA. That matters for an audience that includes older patients and people reading while they are unwell.

This structure was designed for patients and for conventional SEO. It has turned out to be just as useful for AI search, because it spells out what the clinic is, where it is, what it treats and who provides the treatment. A system needs to understand those relationships before it will put an organisation forward for a specific question.

Technical groundwork

Alongside the build, our web team put the standard technical foundations in place: a logical architecture, clean URLs, a maintained XML sitemap, sensible indexation controls and page speed work. None of it makes for exciting reading. It is why a new treatment page or consultant article can be found and indexed quickly, and why the site was in a fit state for AI crawlers to read when that started to matter.

Building authority through specialist content

Castle writes almost everything the clinic publishes. That includes service and treatment pages, guides to specific cancers, awareness pieces and blogs, news about new treatments and trials, and a growing body of consultant-led articles. Clinical content is written from credible medical sources, with NHS and other official guidance as the reference point. An appropriate medical professional then reviews and approves it before it goes live.

That review step adds time to every piece. In cancer care it isn’t optional, and over eight years it has built a library that patients, referrers and search systems can rely on.

Consultants in their own words

The most distinctive part of the programme is how closely the consultants are involved. We interview them, ghostwrite articles from their expertise and publish their commentary on developments in their own fields. So far, we have written, interviewed or produced content for over 10 of their consultants.

Dr Carles Escriu’s article on when lung cancer can be cured, published in January 2026, shows what that produces. It is written in his voice and draws directly on his own work. He contributed to the 2017 European (ESMO) clinical guidelines on early and locally advanced lung cancer, co-authored the international NeoADAURA study on targeted treatment before surgery, and has published real-world results from Liverpool alongside other European centres. The article references all of it in full.

For the reader, it explains in plain terms how giving treatment before surgery has changed the outlook for some early-stage lung cancers. It is candid about where survival data is still awaited. And it explains why Dr Escriu and a thoracic surgeon colleague set up joint consultations for private patients with early-stage disease.

No generic health publisher could write that article, because the information comes from the person who did the research. That is information gain in the literal sense. It also shows expertise and provenance about as clearly as a web page can: a named specialist, verifiable credentials, published research, and an obvious link between the person writing, the clinic’s service and the patients it is for.

Cancer Talks

Castle also produces, records and edits Cancer Talks, one of the consultants, Dr Manal Alameddine, podcast which is produced in partnership with the Clatterbridge Private Clinic. She is a consultant clinical oncologist who specialises in prostate and lung cancers. New episodes are still being made with 5 episodes currently produced and filmed, 3 are live on YouTube and the site currently, with 2 waiting to be published.

The podcast lets a specialist explain her field in her own voice, at length and in conversation. It brings together specialists, healthcare professionals and patients for open, honest conversations about cancer. From the latest treatment advances to real patient experiences and the questions people are often afraid to ask, each episode is designed to make oncology clearer, more human and easier to navigate for everyone. For patients and families, that is often the most reassuring way to get a sense of a consultant before booking an appointment. For search, it attaches the clinic’s expertise to a named specialist in another format.

It also reaches beyond the clinic’s own website. Episodes appear on YouTube as well as on the site, with the potential for them to be added to Spotify, Apple and other podcast platforms. That puts the clinic’s name, Dr Alameddine’s name and the subjects she covers on platforms that search engines and AI systems index separately from the clinic’s domain. Full transcripts published alongside each episode also make the content of every conversation retrievable as text, not only as a recording.

A note on E-E-A-T

We try to be careful with this language. Google doesn’t give a page an expertise score, and E-E-A-T is a framework its quality raters use, not a ranking factor you can dial up.

What search and AI systems do appear to prefer for health topics is content with identifiable authorship, claims that can be traced to reliable sources, and information that agrees with other trustworthy sources. Consultant-led, medically reviewed content meets that standard. It would be worth producing even if search engines didn’t exist, which is probably the best test of whether it’s the right kind of content.

The content we have produced has generated several enquiries for the clinic and secured patients, as it has convinced them to be treated at the private clinic. Most recently, an article we wrote about Dr Ghosal and the Clatterbridge Private Clinic treating the first ever patient with an innovative immunotherapy designed for patients with small-cell lung cancer, generated several enquiries to the clinic from patients looking to get access to this treatment too. The article explained how Clatterbridge Private Clinic was among the first few centres in the UK to offer this promising new therapy to patients, which drove interest and enquiries.

A growing share of health questions are now answered inside an AI Overview, a ChatGPT response or a Perplexity summary before anyone clicks a link. For a clinic whose patients research carefully before making contact, that moves the first impression somewhere new. The answer a patient reads may name two or three clinics, summarise what each offers and suggest what to ask next. A clinic missing from that answer may never be considered.

What we can see so far

We have seen Clatterbridge Private Clinic returned in AI answers when people ask about private cancer care in the North West. The prompts are the kind a patient or family member would type, such as which private cancer clinics there are in the North West, where to get private cancer treatment Liverpool and specific questions such as what private clinic specialise in treatment prostate cancer in Liverpool.

What this shows is that the clinic is in the consideration set for those questions, which is the part that matters commercially.

Making the clinic unambiguous

An AI system will only recommend an organisation it is confident it has identified correctly, and here that is harder than usual. Depending on the source, the same service appears as Clatterbridge Private Clinic, as The Clatterbridge Clinic LLP that operates it, or under the name of the NHS hospital building it sits within. The wider Clatterbridge name also covers an NHS trust, a health park and a separate hospital.

Our approach has been strict consistency wherever the clinic controls the words. The full name is used the same way across the website, social profiles, press material and advertising. Pages state plainly that the clinic is part of The Clatterbridge Cancer Centre NHS Foundation Trust, where it operates and what it treats. Consultant profiles, treatment pages and articles reinforce one another, so that Dr Escriu’s article, his profile and the lung cancer pages all describe the same specialist doing the same work at the same clinic.

Crawler access and structured data

Crawler access comes first because it is binary. If an AI system’s crawler can’t read a page, that page can’t be retrieved or cited. Allowing access doesn’t earn a citation. It only removes a reason there couldn’t be one.

Structured data states explicitly what a page already says in words. This is a clinic, and this is its parent organisation. This is a consultant, with these specialities. This article was written by this doctor and reviewed on this date. We treat it as a way of reducing the chance of the clinic being misread, which matters more than usual given the overlapping names. It isn’t a citation mechanism, and no markup guarantees a place in an AI answer.

Depth across cancers and treatments

When an AI system answers a question about, say, immunotherapy for lung cancer, it looks for sources that cover the subject properly. Eight years of publishing has given the clinic’s site coverage of the cancers it treats, the treatments used for them and the consultants who provide them. Service pages are supported by articles, news and trial updates.

The value lies in the connections as much as the volume. An isolated blog post about a new drug says little about the organisation that published it. Linked to the relevant treatment page, the cancer it treats and the consultant who gives it, the same post tells a system something specific about what this clinic does and who does it.

Writing for retrieval

AI systems generally retrieve passages, not whole pages. A paragraph lifted from the middle of a long treatment guide arrives on its own, without the heading above it or the paragraph before it. So when we write or revise priority pages, we:

  • answer the main question in the opening lines;
  • use headings that match how patients phrase the question;
  • name the treatment, the cancer and the clinic within each section, instead of leaning on “as mentioned above” or “the clinic”;
  • add FAQs where they reflect questions patients really ask.

None of this means reducing clinical content to short answers. Someone researching treatment for a serious cancer needs depth, and a system choosing between sources can tell which ones have it. The aim is a page that answers clearly at the top and then justifies the answer properly underneath.

The questions patients actually ask

People rarely type “private lung cancer treatment Liverpool” into an AI assistant. They ask something closer to what they’d ask a friend who works in healthcare. Where can I get private immunotherapy in the North West? Can I pay privately for cancer treatment if I’ve already been diagnosed on the NHS? Which private clinics near Liverpool treat prostate cancer? Then come the follow-ups about cost, waiting times, insurance and travel.

Those questions carry worries a keyword list never shows. Someone asking about paying privately after an NHS diagnosis is usually concerned about waiting, about a drug that isn’t yet available on the NHS, or about whether going private means giving up their NHS care. Content that addresses the real concern, not only the literal question, is more useful to the patient and more likely to be drawn on by a system trying to answer the whole conversation.

This is where the length of the relationship pays off. After eight years we know which questions the clinic’s patient liaison team hears and which ones consultants are asked in clinic, and in what words.

Keeping clinical information current

Cancer treatment moves quickly, and out-of-date medical information is a risk to patients before it is a ranking problem. At the end of April 2026, Dr Niladri Ghosal treated the clinic’s first patient with Tarlatamab, an immunotherapy for small-cell lung cancer approved by the MHRA but not yet available on the NHS. We produced and published a consultant-attributed article explaining the treatment, with quotes from the consultant and the patient, which was on the clinic’s site on 8 May.

That speed matters for patients searching for a newly licensed drug by name, and for AI systems answering questions about where it is available. It depends on the relationship: we hear about developments early, the consultants are used to working with us and the review process is well practised.

Keeping information current also means maintaining what is already published, which means regular reviews of the site content and blogs, and updating or removing outdated information.

PR and third-party references

AI systems don’t learn about an organisation only from its own website. They also draw on what other sites say about it. In healthcare, a clinic calling itself expert counts for less than several credible sources describing it the same way. Over the years, Castle’s PR, events and partnership work has put the clinic and its consultants in front of audiences it couldn’t reach through its own channels.

The lung cancer campaign

The most recent campaign drew on Dr Escriu’s work on curative treatment for early-stage lung cancer and Dr Ghosal’s first Tarlatamab patient. We turned them into a feature on the clinic’s approach to lung cancer and ran it as a sponsored editorial package across seven regional news sites: the Warrington Guardian, Wirral Globe, Lancashire Telegraph, Bolton News, Westmorland Gazette, Rhyl Journal and The Leader. Each online article links through to the clinic’s website. The package also included two full pages in the print edition of every title, so the feature reached print readers as well as online ones.

We chose the titles for their geography. Between them they cover Wirral, Warrington and Cheshire, East Lancashire, Bolton, South Cumbria and North Wales. All are within reasonable travelling distance of Liverpool and Wirral, and each has a meaningful population of people with private medical insurance or the means to consider self-funding, as determined by the clinic’s own research.

The clinic reported a strong response, and the consultant was approached for interviews afterwards and the article was cited across several other websites.

What it does and doesn’t do for AI search

We should be straightforward about what this was. It was paid-for editorial, labelled as sponsored by the publisher, not news coverage. We don’t present it as independent validation, and we’d be wary of anyone who described a sponsored article that way for GEO purposes.

It earns its place in this story for other reasons. It reached the audiences the clinic wanted, in print and online, with a clinical story told in the consultants’ own words. It led to earned media interest in the consultant. And the story travelled further than the placements themselves. The news platform Ground News aggregated it, and McCollum Consultants, a medico-legal expert-witness firm, later referred to the coverage in an article about how quickly lung cancer treatment is changing. Nobody placed or paid for either of those.

The GEO relevance needs stating carefully. When credible sites describe an organisation consistently, with the same name, the same locations, the same NHS connection and the same named specialists, it becomes easier for a system to recognise that organisation and associate it with particular expertise. That doesn’t cause a citation, and no single article changes an AI answer. What we can say is that the picture of the clinic outside its own website is now more consistent, more specific and more closely tied to lung cancer expertise than it was before the campaign.

Reaching patients beyond Liverpool

The clinic’s patients come from well beyond Merseyside. A consistent thread through the work has been identifying where likely patients live and then staying visible there for long enough to matter.

Across the North West

The regional PR sits alongside out-of-home and broadcast campaigns Castle has produced and managed over the years. These include airport advertising and gate screens, train station sites, bus sides and rears, posters, radio and print.

Their job is familiarity. Nobody books a cancer consultation from a bus advert. But a patient or family member who later hears the clinic’s name from a consultant, a newspaper or an AI assistant is more likely to recognise it and take it seriously. Keeping the brand identical across all of those places is what allows that recognition to build.

The Isle of Man

The Isle of Man work shows the approach most clearly.

Clatterbridge Private Clinic partners with a clinic on the island to provide private cancer services to Isle of Man patients. Some care happens on the island, and patients travel to Liverpool for other parts of their treatment. The journey is short by plane or ferry, and the clinic’s team provides a concierge-style service that helps with travel and hotels. Members of the team also go over to the island for open evenings and meetings with patients and partners.

The marketing had to reflect that whole journey. A campaign telling island residents about a clinic in Liverpool would have left most of their questions unanswered. So Castle has run sustained advertising on the island for more than a year, on buses and at airport gates, alongside collateral for the open evenings and the partner clinic. The gate screens reach island residents while they are making the same journey the service involves.

The clinic reports that the number of patients coming from the Isle of Man has grown substantially over the past two years. That growth belongs to the partnership as a whole: the clinical relationship, the team’s visits and the practical support. The advertising’s role has been to keep the clinic visible and familiar on the island for long enough for the partnership to take hold.

One programme, many channels

The search work sits inside a much broader account, and the scale is worth a brief summary.

Castle designs and publishes the clinic’s organic social content every month, mainly on LinkedIn, Facebook and X. The posts cover awareness campaigns, cancer research, new treatments and trials, clinic and consultant news, events, and the articles we publish on the site. Their main purpose is distribution. They take the consultants’ expertise and the clinic’s clinical news to patients, referrers and the wider professional community, and LinkedIn in particular reaches the consultants, GPs and partners the clinic relies on for referrals.

On paid media, we have run Google Ads to reach people actively searching for private cancer treatment, LinkedIn advertising aimed at professional and referral audiences, and native advertising for wider awareness. Paid media has always been one tool among several, used where it’s the quickest route to a particular audience.

We also help plan and promote the clinic’s open evenings. At these, consultants, referrers, partners and other stakeholders tour the facilities and hear from consultants and the General Manager. We support consultant speaking events and events the clinic hosts or sponsors too.

Then there’s the physical material: brochures and leaflets on specific cancers and treatments, posters, roller banners and branded items for events. It all carries the same brand and is held to the same standard of clinical accuracy as the website.

After eight years, Castle works much like an extension of the clinic’s own marketing team. That is what allows a consultant’s research to become a website article, a social post, a regional feature and an open-evening talk within the same few weeks, all saying the same thing.

Results

These are marketing outcomes. Nothing in this case study is a claim about clinical outcomes, which belong to the clinic and its consultants.

What we can say now

  • Castle and the clinic have worked together continuously since 2018, across 15 disciplines.
  • The clinic appears in AI-generated answers to questions about private cancer care in the North West.
  • The lung cancer feature ran across seven regional news sites and in print in all seven titles. The clinic reported a strong response, a consultant received interview requests, and at least two independent sites picked up the story unprompted.
  • The number of patients coming from the Isle of Man has grown substantially over two years, as reported by the clinic.
