GEO services for hospitals and clinics: Working within medical advertising rules

Hospitals and clinics can use GEO agency services too, earning citations in AI answers with verifiable facts instead of reviews. Article 56 of the Korean Medical Service Act prohibits advertising that risks creating a mistaken impression about treatment effects, such as patient treatment testimonials, so reviews and before-and-after comparisons are ruled out from the start as a way to earn citations. The material you can use is procedures, criteria and costs, and the paragraphs AI carries over into its answers generally contain facts like these.

This article is guidance on content operations, not legal advice. Have the legality of individual wording determined by the relevant review body and through your hospital's internal review.

1. Which media require prior review

A website that a hospital runs on a domain it purchased directly is exempt from prior review of medical advertising, while external platforms with large user bases are subject to it.

Media not subject to review simply skip the prior-review step; the same prohibitions still apply. You can check the conditions for review by medium in the Korean Medical Association Medical Advertising Review Committee's guide to review subjects.

This distinction changes how fast you can publish for GEO. Content that builds up on your own domain can go live as soon as it passes internal review, but for content on large platforms, the advertising review schedule is added directly to the publishing cycle. If you need to move your citation rate within the first three months, focusing on your own domain makes the schedule easier to manage.

2. What content do you write instead of reviews?

Instead of reviews, write factual paragraphs with the hospital as the subject. AI excerpts paragraphs that contain verifiable facts rather than personal impressions, and in medical content, the following types fit that description.

• Procedure and examination steps: Guide readers step by step through preparation, duration, and what happens on the day
• Typical recovery times: State the usual duration and explain that it varies by individual
• Cost breakdown: Set out how each item is calculated and which items are not covered by insurance
• Equipment and certification information: Include approval numbers, when the equipment was introduced, and conditions of use
• Medical staff's areas of expertise: State their subspecialties, academic society activities, and the treatments they provide

"The patient was satisfied" is a testimonial, but "The recovery period for this procedure varies by individual and is typically N to N days" is a procedural explanation. Even when covering the same information, making the hospital the one describing it produces citable paragraphs that avoid prohibited content.

In every medium, leave out claims of definite effects, comparisons of superiority with other medical institutions, and before-and-after photos that could mislead.

3. How do you build the question list?

In healthcare, measurement only works if you build prompts from questions about procedures and conditions rather than diagnoses. For questions that name a diagnosis directly, AI often avoids answering or falls back on generalities like "we recommend consulting a specialist," leaving no place in the answer for a hospital name.

Answers to the questions on the left leave almost no room for a brand, while the questions on the right leave room for documents with factual information to be cited. Fix your prompts to the type on the right, measure the baseline citation rate, and then publish one page for each question. The reason for pairing prompts and pages one-to-one is explained in Content formats and design principles that increase AI search citations.

4. The review process to set before signing a contract

In hospital GEO agency work, schedules usually slip at the review stage. The agency cannot verify medical facts on the hospital's behalf, so you need to set aside separate review time for medical staff with tight clinical schedules.

Before signing a contract, settle the following items.

• Who reviews: Designate, in writing, the person in charge for each department and the final approver
• Review schedule: If your goal is publishing once a week, set a fixed weekly review slot as well
• Advertising review: If you have content going on large platforms, arrange in advance who files the review application and the expected turnaround

If you start without settling these items, drafts just pile up and nothing gets published. Because the citation rate responds only to published pages, results are delayed by as much as review is held up.

5. When to assess results

Assess results after at least three months. The first one to two months go into establishing the baseline citation rate and stabilizing the review and publishing cycle. It typically takes 4 to 12 weeks for a published page to be reflected in AI answers.

Along with how often the hospital's name appears, use the following items to assess results.

• Citation rate on location and department questions
• Actual inquiries that came in via AI referrers
• Whether the hospital's information is cited accurately

There are cases where AI names the hospital correctly but misstates its treatments or location, so information accuracy is a checkpoint separate from exposure frequency.
