YMYL (Your Money Your Life) is the term for all industries Google treats as particularly sensitive, ones that affect health, life, and finances. The algorithms’ expectations for content quality and reliability on these topics are the highest of any sector.

The turning point for the medical industry was the August 2018 Core Update, known in the industry as the “Medical Update,” which forced medical website owners to rethink how they create content on the substantive level. The algorithm gained elements analyzing E-A-T (Expertise, Authoritativeness, Trustworthiness), and in December 2022 Google extended its guidelines with an additional E (Experience).

Building Authority Around Content Authors (Expertise & Authoritativeness)

Every piece of medical content should be verified by an expert, and proof of that verification should be clearly displayed on the page. Below each article, include an author bio containing:

• full name,
• photo,
• link to their profile page on the site,
• education,
• a short description of their specialization and experience.

If the content author is not a medical expert (a copywriter, for example), add a note confirming medical review by a physician. The message can look like this:

Beyond on-site work, it is also worth building the authors’ digital footprint externally (Author Entities). If a doctor or medical expert comments for another medical portal, speaks at a conference, or publishes original research, make sure those publications include the doctor’s full name along with the medical company or facility where they practice.

Frequent mentions and topical associations from credible medical sources help algorithms understand what a given doctor does and strengthen their authority.

Citing Reliable Medical Sources (Trustworthiness)

Medical content should reference established, internationally recognized institutions and research. Citing hard data, statistics, and test results from medical centers builds trust in the brand and the article, which directly supports the T in E-E-A-T (Trustworthiness). Which sources are worth citing?

• Mayo Clinic, the prestigious American nonprofit medical center,
• CDC (Centers for Disease Control and Prevention), the US government’s public health agency,
• WHO, the World Health Organization,
• PubMed, the database of scientific literature in medicine.

On the Polish market, one of the most trusted medical sources is the Medycyna Praktyczna portal, alongside official government institutions such as GIS (the Chief Sanitary Inspectorate), the National Institute of Public Health, and the Agency for Health Technology Assessment, which regularly publishes research reports.

Business and Legal Transparency (Trustworthiness)

Transparent pricing and medical procedures. Clinic websites should clearly state the prices of medical services, treatments, and diagnostic tests, with no hidden extra costs. Patients should also be openly informed about contraindications, potential side effects, and what a procedure involves. Hiding real prices or failing to disclose known risks significantly lowers the algorithms’ trust in sites that do it.

Company details. The website footer should include information confirming the facility’s credibility. What belongs there?

• the full legal name of the entity,
• tax identification number (in Poland: NIP),
• statistical number (REGON),
• commercial register number (KRS, for companies),
• the entry number in the Register of Entities Performing Medical Activity,
• for individual doctors, their medical license number (in Poland: PWZ),
• full address,
• contact details.

Documenting the Real Experience of Staff and Patients (Experience)

The first letter of E-E-A-T stands for experience, and it also needs to be demonstrated and emphasized on the site. How?

• By sharing successes and publishing reports from original research – If a clinic uses innovative treatment methods, can point to high effectiveness of specific therapies, or has performed a complex operation, publish that on the site as news or blog articles.
• By publishing original multimedia – Your own photos of the facility, medical equipment, and staff stand out clearly against the stock imagery many companies still rely on. Video is worth adding too, in the form of expert commentary or interviews, which further underlines the company’s experience and expertise.

Managing External Reputation in the Medical Industry: Link Building and e-PR (Trustworthiness, Authoritativeness)

In the YMYL sector, an e-PR strategy and deliberate link building are essential tools for managing a company’s online image, and at the same time an effective way to build trust and authority.

In link building, drop mass-produced, cheap publications in favor of fewer but high-quality domains with a clear topical connection to the medical industry, publishing verified, high-quality content.

e-PR, in turn, is key to building the image of an expert and industry leader. It is worth running an online press office publishing media information, announcements, press releases, and optimized company descriptions. Monitoring mentions of the brand and its specialists across the web matters too, along with steadily acquiring new, valuable signals from high-authority sites.

Local SEO for a medical company should be built on:

• Google Business Profile – One of the most important touchpoints between a patient and a medical facility. Poor listing management, negative reviews, and missing key information can effectively discourage a user from visiting a given medical center. Ranking the profile itself matters just as much: if the company does not appear in the top map results, users will not notice it at all.
• Review management – Actively collect patient reviews and respond professionally to every one, positive and negative alike. The most commonly checked review sources are Google listings and (on the Polish market) the Znany Lekarz portal, so those two deserve particular attention.
• NAP Consistency – Consistency of NAP data (Name, Address, Phone) is critical in local SEO. All company details should be identical everywhere the listing appears. After an address change or rebranding, remember to update every existing NAP profile.

Why does the local aspect matter so much? Informational queries, centered mostly on blog articles, support brand recognition, but for the medical industry the money keywords, the ones that actually convert, are local phrases.

According to OpenAI’s January 2026 report “AI as a Healthcare Ally,” a full 5% of all queries sent to ChatGPT are medical in nature. Of its more than 800 million regular users, roughly one in four sends at least one health-related message every week, and over 40 million people do so daily. That shows the scale of the opportunity AI tools create for companies in the medical sector.

Researchers at Johns Hopkins University presented interesting results as well. In the study Are older adults using ChatGPT for medical advice?, they asked people aged 50+ whether and how often they use ChatGPT for medical guidance. After adding up the answers “often,” “sometimes,” and “once or twice,” it turned out that as many as 63% of respondents use ChatGPT to obtain medical information.

For medical organizations, the signal is clear: traditional SEO alone is no longer enough. A brand absent from AI-generated answers is losing real market share to competitors who adapted their information architecture to AI algorithms faster, building an advantage that will be hard to close.

For a medical brand to be reliably cited as a credible source in LLMs (ChatGPT, Gemini, Perplexity) and Google AI Overviews, an AISO strategy should rest on:

• The e-PR and link building activities described above. Mentions across the web strengthen brand authority inside AI tools.
• Maximizing information density. LLMs favor concrete content with no filler, packed with data, statistics, and genuinely useful information.
• A BLUF (Bottom Line Up Front) structure in content sections. Placing the key information, even in condensed form, at the very beginning of a text significantly increases the chance of being cited.
• Content lifecycle management. In the medical industry, freshness carries enormous weight, because outdated information can affect a patient’s health. An AISO strategy requires regular, cyclical content verification and updates every 3 to 4 months.

The Synergy of AI Visibility and Local SEO

Building a medical company’s visibility in AI, combined with local SEO, is a perfect match for the patient’s decision path. A user asks ChatGPT about knee pain. The LLM recommends seeing an orthopedist. The user continues the conversation and immediately asks for the best orthopedist in Krakow. They get a list of recommended facilities and names, then move to Google to check reviews and book a visit. If the Google Business Profile is strong and well optimized, the patient completes the process and books the appointment.

AISO thus becomes the top of the funnel (TOFU), and the Google Business Profile the bottom (BOFU).

Structured data is a key element of technical architecture that helps algorithms and bots interpret page content. It allows precise mapping of substantively important elements, such as descriptions of medical conditions or procedures. The choice of Schema markup types should depend on the page type and its purpose:

Implementing structured data also matters from the AISO perspective, that is, ranking in AI tools. It helps LLMs understand the page better, which increases Share of Voice and the site’s overall AI visibility.

Building lasting medical authority in 2026 requires the synergy of several strategies: SEO, AISO, e-PR, and local SEO. Ignoring any of these elements is a silent business risk that translates directly into revenue lost to competitors. If you are planning a visibility strategy for a medical brand, keep these elements in mind:

• Authority of doctors and medical facilities (E-E-A-T): every medical article must be signed and verified by a specific specialist, and the text should reference research and trusted medical sites.
• Content structured for AI (BLUF): place key information and definitions within the first 50 words of the text to increase the chance of the brand being cited by LLMs.
• e-PR activities: lasting visibility is built through presence on reputable health portals, not through mass acquisition of cheap links.
• Structured data (Schema): implementing medical schema eliminates algorithmic misinterpretation and precisely maps the clinic’s profile.
• Local conversion (Local SEO): consistent listing data and rankings for intent-driven city phrases close the sales funnel at the doctor-selection stage.
• Content updates: medical knowledge bases need refreshing every 3 to 4 months, because AI algorithms prefer high-freshness information.
