When a patient asks ChatGPT, “Which dermatologist should I see in Geneva for eczema?”, they no longer compare ten Google results. Instead, they receive a concise answer with two or three names. Patient acquisition in the age of AI refers to all the mechanisms through which an answer engine (ChatGPT, Perplexity, Google AI Overviews) selects and recommends a healthcare provider before the patient even visits a website.
Getting mentioned is only the first step. You also need to turn that interest into appointments. In this article, discover how a platform like OneDoc can help you increase your visibility and book more appointments.

How does AI decide who to recommend?
An answer engine doesn’t “search” in the traditional sense. It selects from content it can read, verify, and cross-reference. A practice that’s invisible online simply doesn’t exist in its answer.
In practice, when a patient asks a question, the model doesn’t rely on its training data (which is too old and not local enough). Instead, it performs a live search (ChatGPT via Bing, Perplexity through its own index, AI Overviews via Google), retrieves a handful of pages, and generates a summary while citing the sources it considers the most reliable and easiest to understand. That’s where the real challenge lies: your pages need to be among those retrieved, and they need to be structured so the model can extract a clear, unambiguous answer. To achieve this, you need to implement Generative Engine Optimization (GEO): improving your visibility in the answers generated by conversational AI.
The four building blocks of AI visibility—and how OneDoc helps you stand out
| Building block | What AI checks | What OneDoc provides |
|---|---|---|
| Retrievable page | The page exists, loads quickly, and isn’t blocked from indexing | A hosted, indexable practitioner profile included in a clean, up-to-date sitemap that loads quickly |
| Structured FAQs (GEO) | Clear question-and-answer pairs that can be extracted as they are | Structured FAQ blocks with FAQ schema on practitioner profiles and listing pages, written in the language patients use |
| Verifiable data | Consistent name, specialty, address, languages, and office hours across multiple sources (NAP) | Accurate and consistent information on your OneDoc profile |
| Actionability | An easily accessible appointment booking link | 24/7 online appointment booking that’s immediately clickable—a strong signal that you’re active and patients can book an appointment right away |
LLMs extract passages, not pages
A well-formatted block containing a question (for example: How long does a first dermatology consultation take?) followed by a direct, complete, and self-contained answer can be retrieved as is.
Where traditional SEO could get by with a keyword-rich paragraph, GEO—which OneDoc continuously strengthens through structured FAQs—ensures that common patient questions receive clear, context-independent answers that LLMs like ChatGPT can extract and use directly.
Being found isn't enough: convert the right patient
Appearing in an AI-generated answer only has value if the patient who clicks is someone you can actually treat. When schedules are already full, the relevance of your profile often matters more than the number of visitors. This is where many practices lose the patient intent they worked so hard to attract.
From recommendation to appointment: how to avoid losing patients along the way
The time between an AI recommendation and a bookable action is the biggest drop-off point in the patient journey. The moment AI mentions your name, the patient’s intent to book an appointment is at its highest. If they then have to look up your phone number, wait for your office to open, or click through several pages, a significant share of that intent disappears.
24/7 online appointment booking eliminates this delay. Patients who find you can book immediately, without interrupting their journey—even in the evening or on weekends, which are precisely the times they are most likely to use AI. It’s the natural extension of the recommendation: from mention to appointment, without friction.
Qualify for relevance: the right patient in the right time slot
This is the point that’s often underestimated. Online appointment booking doesn’t just capture patient intent—it already qualifies it. By selecting the reason for the visit, the appointment type, and an available time slot themselves, patients perform an initial screening without making a single phone call or adding any workload to your front desk.
To reduce this workload even further, Emma, OneDoc’s AI phone assistant, answers incoming calls, qualifies the patient’s intent (reason for the visit, specialty, urgency, needs), and directs them to the appropriate availability instead of letting calls go unanswered.
OneDoc tools to optimize your AI visibility
What AI won't do
Optimizing your presence for AI tools improves your discoverability. However, it doesn’t replace the quality of your patient relationships or the consistency of the care you provide.
- AI doesn’t replace your clinical reputation. A well-structured profile attracts attention, but the quality of your care is what keeps patients coming back.
- AI won’t fix a negative review. If it finds one, it may actually make it more visible. That’s why it’s important to respond to all patient reviews.
- AI can only make you visible if you lay the groundwork. Without an up-to-date page, consistent information across sources, and a way for patients to book online, AI won’t mention you. Local competition and your reputation also play a role. That’s exactly where a GEO strategy makes the difference.
In this context, OneDoc brings together all the technical elements required to be cited (readability, structure, consistency, and freshness) while also supporting your GEO content strategy.
OneDoc at every stage of the patient journey
OneDoc supports both stages of the AI-driven patient journey—from discoverability to conversion—without adding any technical burden to your practice:
- For visibility: an indexable practitioner profile, structured FAQs that answer patients’ real questions, and consistent information across OneDoc, your Google Business Profile, and your website. These are exactly the elements ChatGPT, Perplexity, and Google’s AI Overviews check before recommending you.
- For conversion: 24/7 online appointment booking captures patient intent at the moment it’s strongest and helps increase the number of appointments booked with your practice.
And for handling incoming calls: Emma answers the phone, qualifies patient intent, and keeps your schedule relevant without increasing your front desk’s workload.
Frequently asked questions
As a physician, how can I appear in ChatGPT or Perplexity responses?
By making your information readable and verifiable for AI: an indexable online profile, structured answers to patients’ frequently asked questions (FAQ schema), and consistent information across your website, appointment booking profile, and Google Business Profile. AI models only recommend sources they can read, cross-reference, and consider trustworthy.
What's the difference between traditional SEO and GEO?
SEO aims to rank highly in the list of links returned by Google for a search query, whereas GEO aims to be cited directly in a single AI-generated answer. In other words, SEO rewards pages rich in keywords, while GEO rewards clear, self-contained passages that AI models can extract directly—typically structured question-and-answer content.
Is being visible enough to fill my appointment schedule?
No. Visibility generates interest, but you still need to convert that interest into appointments. Offering 24/7 online appointment booking captures patient intent the moment it arises.
