Hospital marketing is the work of making sure people with a health need find your hospital, trust it enough to book, and keep coming back, within Thailand’s hospital advertising law and personal data law, which are stricter than for most businesses.
In 2026 that job is harder for three reasons: the domestic market is growing slowly, patients compare prices and doctors more before deciding, and many now ask ChatGPT, Gemini or Google AI Mode before they search the usual way. This guide is written from the perspective of HDmall, a health marketplace searched more than 5 million times a month that works with over 2,500 partner clinics and hospitals.
The market: why hospital marketing must change in 2026
An analysis by ttb analytics published in July 2026 describes a structural turning point for Thai private hospitals.
| Figure | What it means for marketing |
|---|---|
| Market of about THB 340 billion in 2026, growing only 2.4% | The market is not growing fast enough for every hospital to grow with it |
| Average growth of 2.0% a year in 2023–2025, against 11.6% in the decade before | What worked in the fast-growth years may no longer be enough |
| Domestic patient numbers up only 0.9% a year | Revenue growth comes mostly from higher prices, not new patients |
| Medical costs rising 10–11% a year against household income growth of about 3% | Patients compare prices for non-urgent care such as health checks |
| Standard health insurance from 20 March 2025 can require 30% or 50% co-payment at renewal when claims meet set criteria | Insured patients think harder before claiming, so clear prices matter more |
| Foreign patients made up 16.8% of revenue in 2025, growing 8.5% a year against 1.3% for Thai patients | International and specialist segments are the clearest growth routes |
The same analysis concludes that hospitals must move from treating illness to managing health over time, through specialist care, aesthetic medicine and prevention. In marketing terms, the job shifts from broad awareness to being chosen at the moment of comparison, and to bringing patients back.
How hospital marketing differs from clinics and other businesses
| Area | Hospitals | What to do differently |
|---|---|---|
| What you sell | Many centres and hundreds of services | Plan and measure by service line |
| Who decides | Patients, families, referring doctors, HR teams and insurers | Give each group the information it uses to decide |
| Who pays | Self-pay, private insurance, group insurance and other schemes | Say clearly which insurers you accept, and offer self-pay packages |
| Decision time | Minutes for urgent care, weeks for surgery | Journeys and messages differ by centre |
| Brand | Doctors and specialist centres carry their own reputation | Be findable by hospital name, centre name and doctor name |
| Regulation | Ads need prior approval; health data is sensitive personal data | Build approval time into plans and separate marketing consent |

The stage that has changed most is search. AI assistants do not show ten links for the patient to choose from; they summarise and recommend a few places. Hospitals without clear facts on their website, such as starting prices, doctors, clinic hours or insurers accepted, often do not appear at all, however well known they are locally.
Eight hospital marketing strategies that work in 2026
1. Plan by centre, not by hospital
Choose three to five centres with spare capacity and good margins, and plan each separately. For each, answer: who the target patient is and what they search for; which competitors they will compare you with, within the distance they will travel; where your price sits; how many more patients the centre can take each week; and what you can afford to pay for one new patient. A health check centre sells on price and convenience; an orthopaedic centre sells on doctors and outcomes. One campaign for both usually serves neither.
2. Be found on Google and in AI answers
SEO for hospitals now means making sure both Google and AI assistants find accurate facts, sometimes called AEO (answer engine optimisation).
- A page per centre and main procedure that answers patients’ real questions: starting price, what is included, preparation, recovery time and insurers accepted
- Doctor pages with specialties, clinic hours and languages spoken (statements about doctors’ qualifications also fall under the advertising law)
- Google Business Profiles that match the website exactly, with separate profiles for centres that have their own entrance, phone or hours, following Google’s guidelines
- Structured data for the hospital, doctors and FAQs
- Steady reviews, with a reply to every one
To check progress, list the 20 questions patients ask most about each centre and ask ChatGPT, Gemini and Google AI Mode every month. The share of questions where you are recommended is your share of AI answers, and it should rise every quarter. HDmall also offers a free online health check of how ready your website and Google presence are. For what changes next year, see 15 healthcare marketing trends for 2027.
3. Publish package prices and be where patients compare
Services patients decide on themselves and compare heavily, such as health checks, vaccines, maternity and planned surgery, should have clear package prices that state what is included and the conditions. Clear prices speed up decisions and cut repetitive chat questions. Beyond your own site, packages should sit where patients already compare. Health marketplaces such as HDmall gather people who intend to buy; one partner’s marketing team told us more than 60% of the customers HDmall sent them were new patients with no hospital number yet.
Planned surgery such as LASIK, cataract, hernia or fibroid surgery is high-value with a long decision path. Patients want help comparing hospitals, checking insurance, finding instalment plans and being looked after on the day. Doing all of that in-house takes a team; the alternative is a surgery concierge such as HDcare, which finds patients, screens cases that are ready to proceed and refers them to the hospital.
Promotions need care: "free", "special" or "discount" without stated conditions and dates is one of the most common reasons ads are rejected.
4. Reply fast and carry the chat through to a booking
A 2011 Harvard Business Review study of 2.24 million inbound leads found businesses took 42 hours on average to respond and 23% never did. It was B2B in the United States, so treat it as a principle rather than a benchmark, but the mechanism is the same: people looking for care contact several places at once, and whoever replies first starts the conversation.
- Bring every channel into one inbox and aim to reply within 5 minutes during opening hours
- Route each chat to the right centre from the first message
- Hand clinical questions to a nurse or doctor immediately, with clear rules on what a person must answer
- After hours, answer automatically with real facts such as prices and availability, and say when the team will follow up
- Track median first response time and the share of chats that end in a booking, by centre
5. Let doctors and education build trust
Health content is what Google calls YMYL (your money or your life), judged on experience, expertise, authoritativeness and trust. Hospitals have the advantage of specialists who can answer questions properly: have doctors write or review articles with their name and review date, make short videos answering common questions, and focus on education rather than outcomes, because content that invites people to use a service or mentions a doctor’s expertise counts as advertising and needs approval.
6. Measure ads all the way to patients who attend
Clicks and chats are easy to see but do not show whether ads pay. The figure that decides is cost per new patient who attends, which means connecting ad, chat, booking and hospital number. Report by centre, because acceptable costs differ. The major ad platforms restrict targeting on health data, so the message and landing page must match the patient’s question. Every creative needs approval before publication, so prepare creatives in batches and leave time for approval.
7. Keep existing patients with CRM and proper PDPA practice
When new patients are harder to find, existing patients are the most valuable source of revenue. Recall programmes with a medical reason work best: annual health checks, the next vaccine dose, post-surgery follow-up and chronic disease care. Health data is sensitive personal data under Thailand’s Personal Data Protection Act, so ask for marketing consent separately from treatment consent, do not upload patient lists to ad platforms without a lawful basis, and work with your data protection officer from the start.
8. Open focused segments: employers, insurers and international patients
- Employers and HR teams buy health checks and services in volume; they want clear quotes, group booking and aggregate reporting
- Insurers and brokers send patients to network hospitals; they want prices, waiting times and direct billing
- International patients are the fastest-growing group; ttb analytics recommends competing on specialist expertise rather than price, for example fertility, gender-affirming surgery and rehabilitation for older people. See our guide to marketing to international patients
Thailand’s hospital advertising law in brief
Section 38 of the Sanatorium Act B.E. 2541 (1998), as amended in 2016, controls advertising of a private healthcare facility’s name, location, services and practitioners’ qualifications or expertise.
- Every ad needs approval before publication. Facilities in Bangkok apply to the Department of Health Service Support (DHSS, กรม สบส.); facilities elsewhere apply to their provincial public health office.
- No false, exaggerated or misleading content, even in an approved ad. Re-check whenever content changes.
- Penalties include daily fines and prison. Advertising without approval carries a fine of up to THB 20,000 plus up to THB 10,000 a day until it stops; prohibited content can carry a prison term.
Enforcement has tightened. From October 2025 to March 2026, DHSS’s legal division checked 4,521 hospital and clinic ad posts and found 2,433 likely to break the law, from 89 facilities, and asked platforms to take posts down. In April 2026 DHSS brought in digital platforms including Facebook, TikTok and HDmall to align on enforcement.
| Risk | Often rejected | Safer approach |
|---|---|---|
| Claims of superiority | "best", "number one", "world-class", "one-stop" | Verifiable facts: beds, year opened, accreditation with the body named, as approved |
| Guaranteed results | "cured for good", "100% safe", "instant results" | Explain the procedure, recovery and real risks |
| Before-and-after images | Comparisons outside professional standards | Only as professional guidelines allow and as approved |
| Promotions without conditions | "free", "special", "discount" with no dates | State the price, inclusions, conditions, start and end dates |
| Drug, device or cosmetic brands | Brand names of medicines or devices in facility ads | Use the service or procedure name instead |
| Patient and influencer reviews | Reviews the hospital pays for or republishes | Treat them as ads and get approval first |
This section summarises the rules for marketing planning and is not legal advice. If in doubt, ask DHSS or your provincial public health office before publishing.
KPIs hospital leaders should track
| KPI | What it measures | Why it matters |
|---|---|---|
| Cost per new patient who attends | Centre marketing spend divided by new patients who actually came | The one figure that says whether marketing pays |
| Share of new hospital numbers | New patients against all patients of the centre | Whether you are growing the base or recycling it |
| First response time | Median, in and out of hours | The fastest place to lose patients |
| Chat-to-booking rate | Chats ending in a booking | Quality of the chat team and the information given |
| Show rate | Patients who attend against bookings | No-shows are a cost already paid |
| 12-month revenue per new patient | All first-year revenue from a new patient | Sets how much you can pay for one |
| Return rate | Patients back within 12 months | The result of CRM and patient experience |
| Share of AI answers | Key questions where AI recommends you | A leading indicator of being found |
| Review score and volume | By centre, on Google and other platforms | Patients compare on it; AI weighs it |
How to set a hospital marketing budget
There is no percentage of revenue that fits every hospital. Work backwards from each centre’s target: set the target from spare capacity, work out gross profit per new patient over 12 months, decide what share of that you will spend to acquire a patient, and multiply. Try your own numbers below; the starting figures are a made-up health check centre.
Marketing budget calculator by service line
- Gross profit per new patient over 12 months
- THB
- Maximum cost per new patient
- THB
- Monthly marketing budget for this service
- THB
The starting figures are a made-up example, not market averages. Treat the budget as a ceiling: if your actual cost per new patient is higher, fix the channel or the booking rate before spending more.
Once you are spending, compare actual cost per new patient with the ceiling every month. Centres below the ceiling with spare capacity are where to add budget first.
A 90-day plan
- Weeks 1–2, audit: pick three centres, ask AI each centre’s 20 key questions, measure 30 days of chat response times and gather the approval numbers of current ads
- Weeks 3–6, foundations: build centre pages with prices and doctors, align Google Business Profiles with the site, bring chats into one inbox and set up measurement through to bookings
- Weeks 7–10, scale: list packages on marketplaces, launch approved ad sets and start doctor-led content
- Weeks 11–13, review: cut what costs more than the ceiling, add budget where it works and start recall for existing patients

Frequently asked questions
Where should a private hospital start with marketing?
Pick three to five centres with spare capacity and good margins, then measure three things before spending more: how often AI and Google recommend you, how fast you reply to chats, and the cost per new patient who attends for each centre. Those three figures show what to fix first.
Do hospital ads in Thailand need approval?
Yes. Under section 38 of the Sanatorium Act, advertising a facility’s name, location, services or a doctor’s qualifications or expertise needs approval before publication. Bangkok facilities apply to DHSS; others to their provincial public health office. Advertising without approval can be fined up to THB 20,000 plus up to THB 10,000 a day until it stops.
How much should a hospital spend on marketing?
There is no standard percentage. Work by centre: multiply the new patients the centre can take by the maximum you can pay for one, which comes from gross profit per new patient over 12 months and the share of it you are willing to spend. The calculator in this guide does the sum.
How do ChatGPT and Google AI Mode affect hospital marketing?
AI assistants summarise and recommend a few places instead of listing links. Hospitals with clear facts on their website, such as starting prices, doctors, clinic hours, insurers accepted and steady reviews, are more likely to be recommended. Ask AI your key questions every month to see where you stand.
How is marketing a public hospital different?
The Sanatorium Act mainly covers private facilities; public hospitals follow their parent agency’s rules and usually aim at public health communication and access rather than new patients. Clear information, fast replies and continuing care apply to both.
