Summary
Forty million people ask ChatGPT health-related questions every day, according to OpenAI’s 2026 data. That’s roughly 12% of the global internet population turning to AI for their first medical opinion. Traffic from AI platforms grew 527% year-over-year in 2025, while Gartner predicts traditional search volume will drop another 25% by 2026. The problem for healthcare organizations is structural: AI systems cite aggregators like WebMD over specialized clinics because aggregators have content architecture optimized for machine consumption.
Your hospital might have world-class clinical expertise, but if that expertise isn’t structured for AI visibility through verified author credentials, primary-source citations, and YMYL compliance, it remains invisible to the systems patients use. The healthcare GEO framework has five layers: crawlability and indexing; content architecture for clinical authority; external authority development; YMYL compliance and safety signals; and structured data implementation. Healthcare organizations that move through all five layers typically take 6-12 months to see significant changes in AI visibility, but the returns compound as clinical authority strengthens.

How hospitals and healthtech companies win in generative search when 40 million people ask ChatGPT health questions daily
Last Tuesday, a 34-year-old woman with persistent vertigo didn’t call her neurologist. She opened ChatGPT.
This isn’t an anecdote. It’s your market baseline. In the US, 39% of Americans trust AI chatbots for healthcare decisions according to 2025 survey data, and 3 in 5 US adults have actively sought medical advice from ChatGPT or other AI systems.
Here’s what that means for your healthtech business: the moment someone types a symptom, a medication name, or a procedure into an AI system, they’re bypassing Google. They’re not clicking your website. They’re not reading your thought leadership. The AI system is synthesizing an answer from sources it trusts, and your hospital’s domain isn’t in that trust set unless you’ve deliberately built for it.
The real risk isn’t that patients won’t be able to find healthcare information. It’s that they’ll find the wrong sources, and your clinical expertise won’t be among them. When a patient trusts information that contradicts your hospital’s clinical protocols, patient safety suffers. When a patient’s first interaction with healthcare information comes from an AI system that cites a generic health platform rather than your specialized center, trust shifts to the aggregator, not to you.
That woman with vertigo? She got a decent overview from ChatGPT. But the AI didn’t cite her local neurologist. It didn’t recommend the balance disorder clinic, 15 minutes from her home. It cited WebMD and a general medical reference. She’ll probably call her primary care doctor now, adding to wait times for conditions that specialist clinics could have diagnosed faster.
This is the new search landscape. And your visibility strategy needs to change accordingly.
Why your healthtech brand is invisible to AI (and why it’s dangerous)
You publish good clinical content. Your hospital’s protocols reflect current evidence. Your doctors have authored papers. Your surgical outcomes are better than regional averages. And yet, when an AI model indexes your website, it doesn’t recognize your authority.
There are three structural reasons for this, and none of them are about content quality.
First: AI models cite aggregators, not specialists. When an AI system has been trained on millions of web documents and needs to answer a patient’s question, it defaults to sources that are proven consistent and broad. WebMD answers 200 conditions. Your hospital’s ENT department answers 8 excellently. From an AI indexing perspective, WebMD is more “authoritative” because it covers more ground, even if your department would give a better answer in your specialty.
The aggregator problem has consequences. In the 2025 Qwairy study, Perplexity cited 21.87 sources per question, compared with ChatGPT’s 7.92. That means Perplexity is pulling from broader datasets, which favors encyclopedic platforms over specialized clinics. Your specificity, which creates patient trust in the real world, actually works against you in AI training datasets.
Second: 70% of searches now end without a click. AI Overviews on Google are answering questions directly, pulling information from multiple sources, and synthesizing it. According to BrightEdge’s December 2025 data, treatment and procedure queries now have an AI Overview presence in 100% of results, up from just 45% in 2023. Symptoms and conditions queries appear in AI Overviews 93% of the time, up from 57% in 2023.
For the healthtech space, this shift is catastrophic. You’re competing for inclusion in AI Overviews, not for ranking position. The rules are entirely different. Ranking for position 1 doesn’t guarantee inclusion in the AI answer.
Third: Medical disclaimers disappeared from AI models, but clinical scrutiny didn’t. In 2022, 26% of medical AI outputs included appropriate safety disclaimers and source attribution. By 2025, that number dropped below 1%. AI systems are making confident medical statements without hedging. But the systems that generate those statements are applying the highest scrutiny to source reliability, fact-checking, and authority verification for medical content.
You need to be indexed by AI systems as a trustworthy clinical source. That means meeting YMYL standards (Your Money, Your Life) that Google applies to healthcare, plus passing the additional vetting that AI systems layer on top.
The 3 types of AI crawlers: what healthcare brands must know
When you think about AI visibility, you’re actually managing visibility across three different crawler architectures. Each has different indexing rules, different citation preferences, and different ways of evaluating source authority.
Type 1: search engine AI Overviews (Google, Bing)
These systems crawl your website the same way Google’s traditional index does, but they apply additional filters when synthesizing medical content. Google’s AI Overview system has explicit rules about medical content. It won’t cite sources with quality issues, medical misinformation flags, or poor E-A-T signals.
The advantage: you’re already in Google’s index. The AI Overview just adds a higher bar. The disadvantage: you’re competing against every other healthcare source Google has indexed, including aggregators with broader coverage and stronger brand recognition.
Type 2: generative AI (ChatGPT, Claude, etc.)
These models were trained on data through specific cutoff dates and don’t crawl the web in real time. They can’t access your newest content. They can’t keep up with your hospital’s latest initiatives. They’re citation engines that synthesize answers and cite sources they were trained to recognize as authoritative.
ChatGPT is selective about medical sources. It tends to cite academic databases, government health resources (FDA, NIH, CDC), major medical organizations, and broadly recognized platforms. It rarely cites individual hospital websites unless that hospital has significant brand recognition or media presence.
Getting indexed here means building external authority signals beyond your website, such as published research, clinical partnerships, media mentions, and inclusion in medical databases and directories. This is a 6-18-month play, not a quick fix.
Type 3: AI search engines (Perplexity, You.com, etc.)
These systems crawl the web in real time, similar to Google, but with different ranking priorities and citation strategies. They’re aggressive about including multiple sources in their answers, which can work in your favor (more citation opportunities) or against you (your specialty gets diluted among general sources).
Perplexity’s algorithm favors recency and breadth. It wants to show users that it’s pulling from current, diverse information. This gives newer healthcare content a chance to rank, even if it hasn’t built traditional SEO authority.
All three crawler types care about source credibility, but they evaluate it differently. Your optimization strategy must address crawlability and indexing for all three, while recognizing that authority signals vary by system.
YMYL: Why AI applies highest scrutiny to health content
Google coined the acronym YMYL (Your Money, Your Life) to describe content categories where inaccuracy causes real harm. Healthcare belongs in the highest-risk tier. When you’re writing about diagnostics, treatments, medication, or patient outcomes, a mistake isn’t a ranking penalty. It’s a patient safety issue.
This matters because YMYL standards used to be about ranking factors. Now they’re becoming gating factors for AI visibility. An AI system that cites health information knows it’s potentially influencing medical decisions. That creates legal, ethical, and reputational risk for the AI company. The response has been defensive: AI systems are applying extreme scrutiny to healthcare sources.
Google’s 2024 Product Review Update and September 2025 “Perspective” update both targeted healthcare domains specifically. The September update caused an average 15% drop in search impressions for clinics with generic, non-differentiated content.
Here’s why that matters for your CMO strategy: you can’t compete on healthcare volume anymore. Publishing another guide to “10 symptoms of depression” won’t build visibility. AI systems and Google’s algorithm both recognize that as commodity content. Your clinical value needs to be demonstrable, specific, and hard to replicate.
YMYL compliance for AI visibility requires author credibility at the byline level, source attribution within content, owthregulatory and professional affiliation signals, and clear distinction between medical information and marketing.
Case study: How Digbi Health achieved 500% organic traffic growth
Digbi Health is a digital nutrition company focused on personalized nutrition recommendations and health tracking. They started with a challenging positioning: competing in a space crowded with general health platforms, nutrition apps, and direct-to-consumer supplement companies. Their clinical differentiator was real, they worked with registered dietitians and published research, but that authority wasn’t visible to either Google or AI systems.
When upGrowth began working with Digbi Health, the first audit revealed a critical gap: their content was clinically sound but architecturally invisible to AI crawlers.
The optimization involved three core changes.
First: content restructuring for crawler clarity. Digbi rewrote their nutrition guides to lead with clinical evidence, authored by specific RDs with credentials, citing specific research. They separated their “clinical education” section (credential-based, evidence-driven) from their “product recommendation” section (marketing-appropriate, clearly labeled).
Second: author authority development. Digbi’s registered dietitians went from anonymous contributors to authored voices. Each guide carried the byline “By Katherine Morris, MS, RD, LDN, registered dietitian, 8 years clinical nutrition experience.” They created author pages with verifiable credentials.
Third: structured data and regulatory signals. Digbi implemented structured data that helped Google and AI systems parse author credentials, clinical sources, and content type. They added signals that connected their recommendations to established clinical organizations without making false claims.
The result: 500% organic traffic growth in three months.
That number deserves context. The growth came from two sources: first, significant traffic increases from AI Overviews and AI search engines citing their clinical guides (estimated 35% of the growth). Second, improved ranking for treatment and condition-related queries where AI visibility is highest (estimated 65% of the growth).
More importantly: the traffic quality changed. Their content was now attracting patients searching for specific clinical information, not just general health interest. Their bounce rate dropped because the traffic was intent-matched. Their conversion to consulting services improved because patients arriving from AI-driven traffic came with specific clinical questions.
The Healthcare GEO framework: From invisible to trusted authority
Generative Engine Optimization is distinct from SEO, and healthcare requires the most careful distinction. SEO optimizes for human-readable ranking factors. GEO optimizes for machine-readable authority factors that AI systems use when synthesizing answers.
The framework has five layers, applied in sequence.
Layer 1: Crawlability and indexing
This is table stakes, not strategy. Your clinical content needs to be crawlable by Google, Bing, Perplexity, and other major AI systems. Most hospital websites fail this layer because their content management systems were built for human navigation, not crawler navigation.
Audit your site for these specific failures: clinical guides locked behind paywalls or login requirements, video-only content without transcripts, important clinical information on redirect chains, and duplicate content across multiple URLs.
Layer 2: Content architecture for clinical authority
This is where most healthcare sites fail. Your clinical content needs to signal expertise to machines, not just to humans. That means separating clinical education from marketing, providing author credentials at scale, and including primary sources and citations.
Layer 3: External authority development
Your website authority can’t exceed your broader clinical reputation. If your hospital has strong E-A-T signals outside your website (clinicians publishing research, participation in clinical networks, media mentions, professional society memberships), those signals boost your website’s authority with AI systems.
This layer is slow. It’s a 6-18 month play. But it compounds. One published research paper creates multiple authority signals that appear in PubMed, get cited by other researchers, appear in media summaries, and become byline elements for the authoring clinician.
Layer 4: YMYL compliance and safety signals
This is distinct from content quality. YMYL compliance means signaling to AI systems that you take patient safety seriously through medical disclaimers and hedging language, conflict of interest transparency, and clinical controversy handling.
Layer 5: Structured data and machine-readable authority
This is the technical layer that ties everything together. You’re providing AI systems with structured data about author credentials, clinical guidelines, content type, and source reliability. Schema markup tells AI systems: this is a medical article, authored by a verified clinician, sourced from these clinical databases, published on this date, suitable for this type of query.
This framework isn’t quick. A healthcare organization moving through all five layers typically takes 6-12 months to see significant AI visibility changes. But the returns compound as your clinical authority strengthens in the eyes of AI systems.
Your 30-day action plan for healthcare AI visibility
You can’t transform your visibility in 30 days. But you can start building the foundation that will compound over the next 6-12 months.
Days 1-3: baseline audit. Audit your top 20 condition and treatment keywords for AI Overview presence. Check Google, Perplexity, ChatGPT, and Claude. For each query, note: does my hospital appear? If yes, in what position? If no, which competitors are cited?
Days 4-6: content audit. Identify your top 10 clinical guides. For each one, answer: is this authored by a specific clinician or anonymously? Does it cite primary sources or rely on vague attribution? Is it separated from marketing content? Does it have medical disclaimers?
Days 7-10: author strategy. Identify 3-5 clinicians who’ll author your top clinical guides going forward. Work with them to create author pages with verified credentials, publication history, board certifications, and professional affiliations.
Days 11-15: GEO service setup. If you’re in the healthcare space and your competitive position is slipping, you need dedicated GEO strategy, not traditional SEO maintenance. Decide: will you build this capability internally or work with a specialist?
Days 16-20: content restructuring plan. For your top 5 clinical guides, create a content restructuring plan. Separate educational content from promotional content. Identify needed clinical citations and primary sources. Map author assignments.
Days 21-25: quick wins. Implement three quick technical fixes: ensure your clinical guides are crawlable and not behind paywalls, add author bylines with credentials to your top 10 clinical pieces, and implement basic medical article schema markup.
Days 26-30: team alignment and roadmap. Get stakeholder alignment on your GEO strategy. Create a 6-month roadmap with specific milestones focused on content architecture, author development, external authority building, and AI monitoring.
Your clinical expertise deserves to be visible
The healthcare organization that executes this roadmap in 6 months typically sees 30-50% improvement in AI citation frequency within their key specialties. The improvement compounds because each clinical guide that gets cited by AI systems builds credibility for the next guide.
upGrowth has worked with 150+ healthcare clients solving this exact problem, from digital nutrition companies to specialty clinics facing AI visibility gaps. Our healthcare marketing services are built specifically for the compliance and authority requirements healthcare content demands. We help hospitals and healthtech companies build the content infrastructure that makes clinical expertise visible to the AI systems patients are already using.
If you want to understand where your clinical content stands today and what it would take to dominate your specialty in AI citations, the first step is a structured diagnostic that maps your current AI visibility against your competitors.
1. If I’m ranked position 1 in Google, shouldn’t I already be in AI Overviews?
Not necessarily. AI Overview inclusion depends on AI-specific trust factors that differ from ranking factors. You might rank position 1 for a treatment query, but if your content has weak author credentials or low clinical citation density, it won’t be selected for the AI Overview even though it ranks. Position matters, but it’s not determinative.
2. How long before we see results from GEO optimization?
First signals appear in 4-8 weeks for crawlability improvements and schema markup implementation. Meaningful AI citation frequency growth takes 3-6 months with strong execution. Significant traffic impact takes 6-12 months as external authority signals accumulate and your clinical guides get cited across multiple AI systems. It’s slower than traditional SEO ranking changes because it depends on building credible author profiles and external authority, not just on-page optimization.
3. Do I need to hire clinical writers or can my marketing team write clinical content?
Your marketing team can oversee structure and strategy. Your clinicians need to author the actual clinical content. AI systems are increasingly verifying that clinical claims come from verified healthcare professionals. Generic hospital content teams lack the credentials AI systems check. The byline needs to be the clinician, not the hospital.
4. Our hospital is NABH-accredited. How do we signal that to AI systems?
Add NABH accreditation to your organization schema markup. Structure your data to include accreditations, certifications, and regulatory approvals. Make sure your Organization schema includes accreditationStatus, accreditor references, and certification dates. This tells AI systems your clinical credentials are verified by external standards bodies.
5. Should we stop doing traditional SEO and focus only on GEO?
No. They’re complementary. Traditional SEO still drives traffic. It’s just declining as a percentage of total healthcare discovery. Crawlability (SEO foundation) enables GEO. Ranking position still helps with AI Overview inclusion. Rough allocation: 40% traditional SEO maintenance, 40% GEO-specific work (content architecture, author development, authority building), 20% monitoring and experimentation across both.
6. Can we use AI to write our clinical content faster?
Not for clinical authority purposes. AI-generated clinical content is a red flag for the very AI systems you’re trying to impress. Use AI tools for research synthesis, outlining, and editing, but human clinicians need to author the final medical claims. AI systems can detect whether content was generated by machines. It impacts their trust scoring negatively.
For Curious Minds
The aggregator problem describes how AI models prioritize broad, encyclopedic sources over specialized, expert ones. This happens because AI training favors platforms like WebMD that cover thousands of topics, viewing their breadth as a sign of authority, even if your hospital's content on a specific condition is clinically superior. The direct consequence is that your specialized knowledge gets overlooked. This issue is magnified by models like Perplexity, which cites 21.87 sources per query, pulling from a wide net that naturally favors aggregators. To counter this, you must adopt a strategy of structured data and explicit entity recognition. Your goal is to make your specialized authority machine-readable, ensuring your expertise is not lost in the AI's preference for generalization. Find out how to restructure your content in the full article.
AI systems have become the new front door for health inquiries, intercepting patients before they ever reach a search engine or a provider's website. With 3 in 5 US adults having used AI for medical advice, patients now receive synthesized answers from sources the AI trusts, which may not include your hospital's specific clinical protocols. This creates a serious risk of patients receiving generalized or even contradictory information that conflicts with your evidence-based care guidelines, potentially delaying proper diagnosis or leading to unsafe self-care decisions. When an AI response omits your specialized clinic, as seen with the vertigo patient example, it directly impacts patient outcomes and trust. Understanding this new, AI-mediated patient journey is the first step to re-establishing your clinical authority.
The key difference lies in their sourcing breadth and citation habits, which directly impacts your content strategy. Perplexity, for example, is far more likely to draw from a wide range of sources, citing an average of 21.87 per query according to the Qwairy study. This favors content that is widely distributed and recognized across multiple domains. In contrast, ChatGPT cites fewer sources (7.92), suggesting it relies on a more consolidated set of highly authoritative domains. Your strategy must be twofold: aim for broad syndication to appear in Perplexity's wider net, while also focusing on deep, structured authority signals to earn a spot in ChatGPT’s more selective trust set. The choice of where to focus depends on your resources and goals, a topic explored further in the complete guide.
The data reveals a near-total takeover of the search results page by AI. According to BrightEdge, the presence of AI Overviews for treatment and procedure queries surged from 45% in 2023 to 100% by December 2025. This means for every single one of these searches, Google provides a synthesized answer at the top, effectively making traditional rank-one positions less valuable. This shift transforms the goal from just ranking high to being a cited source within the AI Overview itself. Since 70% of searches now end without a click, failure to be included in that summary answer renders your content invisible to the vast majority of patients seeking information. Your entire SEO focus must pivot from ranking to AI inclusion.
This example highlights the dangerous disconnect between patient need and AI-provided solutions. The AI gave a generic answer citing WebMD but failed to identify the local, specialized balance disorder clinic just 15 minutes away, which would have been the most clinically appropriate next step. This demonstrates how AI systems, by default, cannot yet map specific patient symptoms to specialized, geographically relevant care providers. Your clinic's expertise becomes invisible. The patient is instead funneled back into the general primary care system, increasing wait times and delaying specialized diagnosis. This proves that your digital strategy must now focus on explicitly signaling your specialty and location in a machine-readable format so AI can make these critical connections.
This statistic signals a profound transfer of trust from traditional institutions to algorithmic systems. Patients are increasingly viewing AI chatbots as a legitimate and accessible first point of contact for medical information, bypassing their doctors or hospital websites. The primary implication is that clinical authority is no longer solely determined by your reputation or published research, but by your visibility within AI training sets. If your organization's expertise is not represented in the answers provided by systems like ChatGPT, patients will place their trust in the sources that are. This erosion of direct institutional trust requires a proactive strategy to inject your validated clinical content directly into these AI ecosystems. Learn more about reclaiming that trust in the full analysis.
The goal is to make your specialized authority legible to machines. Instead of focusing on keywords for ranking, you must prioritize signals that demonstrate expertise for AI inclusion. Here is a starting plan:
Structure Your Data: Implement detailed schema markup for medical procedures, conditions, and physicians. Clearly define your specialty, treatment outcomes, and location so AI models can easily parse who you are, what you do, and who you serve.
Create Definitive Source Content: Develop comprehensive, evidence-based guides on your core specialties. These should be formatted as canonical sources that directly answer patient questions, making them ideal citation material for an AI.
Build a Knowledge Graph: Internally link your content to establish clear relationships between your doctors, the conditions they treat, the procedures they perform, and the outcomes they achieve. This helps AI understand your domain of expertise.
This foundational work is critical for survival in a search landscape where 70% of searches end without a click.
This zero-click reality requires a fundamental shift from driving traffic to building presence. Your new primary goal is not to get a click, but to be the trusted, cited source within the AI-generated answer itself, because that is your new "first impression." This means you must invest in strategies that build brand recall and authority at the point of the AI summary. Long-term adjustments should include: focusing content on being citable and quotable, measuring success by "share of voice" in AI answers rather than website visits, and creating direct-to-patient channels to own the relationship after the initial AI-mediated query. Your brand must exist within the AI ecosystem, not just hope for a click from it.
The disappearance of disclaimers creates a dangerous illusion of certainty for patients. When an AI provides a medical answer without caveats, users are more likely to perceive it as a definitive clinical recommendation, elevating the risk of misinformation and potential harm if the source material is weak. This makes it strategically imperative for your hospital to be the cited authority. If your content is the source, you ensure the information aligns with your clinical protocols and safety standards. This is no longer a marketing goal, it is a risk management imperative. Ensuring your hospital is the trusted entity behind the AI's answer is the only way to maintain clinical governance over the information patients receive in this new environment.
Your content is invisible because AI models are not trained to evaluate clinical quality, they are trained to recognize patterns of authority at scale. The primary structural issue is that AI defaults to broad aggregators like WebMD because their vast volume of content on thousands of topics creates a stronger "authority" signal in the training data than your hospital's deep expertise on a few dozen conditions. The AI misinterprets breadth for authority. The solution is not to create more content, but to make your existing expertise more machine-readable through structured data, clear entity definition, and a robust internal linking framework that explicitly demonstrates your specialized knowledge graph. You must teach the AI why your focused expertise is more valuable than a generalist's overview.
The most significant error is treating it as a marketing or SEO problem instead of a critical patient safety and trust issue. When your clinical protocols are not reflected in AI-generated answers, a dangerous gap emerges between the advice patients receive and the care you provide. Forward-thinking systems address this directly by proactively working to inject their validated clinical information into these AI ecosystems. They avoid this pitfall by:
Auditing their content for machine-readability.
Creating definitive, citable guides for their core specialties.
Using structured data to explicitly label their expertise, physicians, and outcomes.
They understand that in a world where 39% of Americans trust AI for health advice, ensuring the AI's answer is your answer is a core function of modern healthcare delivery.
You must pivot your content creation from a narrative-driven to a data-driven process designed for machine consumption. This involves treating every piece of content as a potential data source for an AI, not just a blog post for a human reader. A successful process includes:
Answer-First Formatting: Structure content to directly answer a specific question in the first paragraph, making it easy for an AI to lift as a featured snippet.
Entity-Centric Writing: Explicitly define and link key entities to authoritative sources and internal knowledge hubs.
Data-Backed Claims: Embed specific data points and statistics, like the BrightEdge finding that AI Overviews appear in 100% of treatment queries, to signal authority and verifiability.
This structured approach is essential for becoming a trusted source in the zero-click search era.
