The verdict in three sentences
In Frankfurt, a banker relocating from London, an ECB staff member or a local professional weighing veneers or aligners now often asks AI assistants like ChatGPT for a shortlist of practices, in English or in German, before reading a single review site. The practices that appear are those with clear, consistent public information: dentists' qualifications, treatment pages with honest price ranges, an up-to-date Impressum, genuine reviews and mentions outside their own website. Work on this kind of visibility typically costs EUR 1,500 to 4,500 a month on the 2026 market, and it can only be judged on a dated record of the answers given to the same questions over several months.
What Frankfurt patients ask AI assistants before booking
Questions combine a treatment, a language need and a district. Many patients are international and want care in English, which changes which practices are described.
| Question asked to an AI assistant | Language | What the patient really wants to know |
|---|---|---|
| Which dentists in Frankfurt do porcelain veneers and speak fluent English? | English | Qualifications, language, before booking a consultation |
| Was kosten Veneers in Frankfurt und welche Praxis ist auf ästhetische Zahnmedizin spezialisiert? | German | Price range and specialisation |
| Does German public health insurance cover veneers or clear aligners? | English | Whether the cost is out of pocket |
| Which practices near the Westend or Bankenviertel offer early morning appointments for aligner check-ups? | English | Convenience for a working day in the city |
| Are dental implants in Frankfurt cheaper than in Zurich or London? | English | Value compared with home country |
| Which Frankfurt practices offer financing for a full smile makeover? | English or German | Payment options for a EUR 10,000+ treatment |
| What should I ask at a cosmetic dentistry consultation in Germany? | English | Process, risks, aftercare |
A practice that has never checked these answers does not know whether it is recommended, ignored, or described with outdated information.
Why some practices appear in answers and others do not
AI assistants build answers from what is written publicly. Gaps, contradictions or information locked inside images reduce the chance of being named, or produce inaccurate descriptions.
| Factor | What AI assistants use | Frequent gap in Frankfurt practices |
|---|---|---|
| Consistent public information | Same name, address, dentists and hours across the site, Impressum and directories | Departed associate still listed, old opening hours on map listings |
| Treatment pages with facts | Indications, steps, duration, aftercare and a price range per treatment | One generic page for all aesthetic treatments |
| Qualifications stated precisely | Degrees, specialist titles actually held, memberships | Vague phrasing, titles only in German |
| Content in both languages | Native German and English pages | English pages machine-translated or missing |
| Reviews collected properly | Genuine, recent reviews in both languages | Few recent reviews, or none mentioning cosmetic treatments |
| Third-party mentions | Local press, expat guides, professional society listings | No presence outside the practice website |
| Structured data and freshness | Machine-readable practice details, dated updates | Nothing updated since the last redesign |
German rules shape what you can say. Medical advertising falls under the Heilmittelwerbegesetz (HWG) and the professional code of the regional dental chamber, which restrict some forms of advertising, testimonials and before and after imagery. The GDPR and the BDSG apply to forms and booking tools, so health data should stay out of simple contact forms, and the Impressum duty applies to the site. This is not legal advice: have your patient-facing content checked by your own adviser.
What this work covers and what it costs
In broad terms, it means recording how AI assistants describe the practice today, correcting inconsistent public information, improving factual treatment pages in German and English, earning credible outside mentions and tracking the answers over time. It overlaps with local SEO but is judged differently.
| Type of engagement | 2026 ballpark | Typical scope |
|---|---|---|
| One-off diagnostic, one language | EUR 2,000 to 4,000 | 25 to 40 questions, accuracy check, priority list |
| One-off diagnostic, German and English | EUR 3,000 to 6,000 | Same scope in both languages |
| Monthly program, single practice | EUR 1,500 to 3,000 per month | Page updates, listings, monthly answer tracking |
| Monthly program, several dentists or locations | EUR 3,000 to 4,500 per month | More pages and profiles, outside mentions |
| Add-on to an existing SEO contract | EUR 600 to 2,000 per month | Tracking and adjustments on top of SEO |
These are prudent ranges from typical agency quotes in Germany and public rate pages; the market is young and offers vary widely. Kolonell prices this work on quote, and no one can promise that an AI assistant will recommend a particular practice.
How to tell whether it is working
Keep a fixed list of questions, asked monthly in German and English, with answers saved and dated. Three numbers matter: the share of answers naming the practice, the accuracy of what is said about dentists, treatments and prices, and whether the practice is presented as a recommendation or only listed. Allow at least six months, since answers vary between sessions.

Mini case study
Illustrative example: "Westend Smile Studio", two dentists focused on veneers and aligners, many English-speaking patients. A dated record of 36 questions (18 in English, 18 in German) names the practice 3 times, an 8% share (3 ÷ 36 = 0.083), and one answer gives a wrong address.
Budget considered: a two-language diagnostic at EUR 3,500, then six months at EUR 2,500 (market assumption), a total of 3,500 + 6 × 2,500 = EUR 18,500. With an average veneer case worth EUR 8,000 (market assumption), three additional cases traced to these channels would cover the cost (3 × 8,000 = EUR 24,000; two cases would leave EUR 2,500 uncovered). The stop rule is set beforehand: no improvement in share or accuracy after six months, the program ends.
FAQ
Do AI assistants like ChatGPT treat German and English questions the same way?
Not always. A practice described well in German can be absent from English answers, which matters in a city with a large international workforce; a two-language diagnostic typically costs EUR 3,000 to 6,000 on the market.
Should we publish prices for veneers and aligners?
Price ranges (for example per veneer or per aligner treatment) help both patients and AI answers, as long as they are accurate and state what is included. Fixed promises are risky because every case is assessed in consultation.
Can reviews mention treatment results?
Genuine reviews are useful, but advertising rules in Germany limit how practices use testimonials and results. Collect reviews openly, never pay for them, and avoid reposting them as advertising without checking the rules.
How long until changes appear in AI answers?
Corrections usually take a few weeks to several months to show. A fair evaluation window is 3 to 6 months of monthly tracking on 25 to 40 questions.
What does a first diagnostic include?
Typically a set of 25 to 40 questions in one or two languages, recorded answers, an accuracy review and a list of fixes. Market prices run from about EUR 2,000 to 6,000.
