The verdict in three sentences
Geneva and international buyers of high-end new builds now put their first questions to AI assistants like ChatGPT before calling a broker, and the answer names a handful of developers, rarely more than three or four. A developer shows up when public information about it is consistent, factual and verifiable across several sources, not simply when its website looks good. This work is measured with a dated record of the answers to the same questions, month after month, and costs 3,000 to 9,000 CHF a month on the market (2026 ballpark).
What buyers ask AI assistants in Geneva
The typical profile has not changed: a Geneva family moving up, a senior staffer at an international organisation, an entrepreneur relocating from Paris, London or the Gulf. What has changed is the first move. Instead of typing "developer Geneva" into a search engine, many write a full question, in French or English.
| Question asked to an AI assistant | What the buyer really wants | What the answer needs to find |
|---|---|---|
| "Which developers are building luxury apartments in Geneva in 2026?" | A short, credible list | Named current projects, districts, public timeline |
| "Reliable developer on the left bank, delivers on time?" | Delivery track record | Real past projects, delivery dates |
| "New apartment with lake view in Cologny or Vésenaz, who is developing?" | Exact location, scheme | Indexable project page, location, unit types |
| "Can a foreigner buy a new build in Geneva?" | Purchase framework | General explainer page, referral to a notary |
| "Off-plan versus completed property in Switzerland, what is the difference?" | Off-plan risks | Sourced explainer content, steps, general safeguards |
| "Geneva developer with contemporary architecture and an energy label?" | Architectural signature | Named architects, labels actually obtained |
| "Contact for a developer of new villas in Anières?" | A person to talk to | Clear contact details, stated response time |
None of these questions is about website design. They are about facts: who, where, when, with what track record. An AI assistant can only cite what it finds and cross-checks.
Why some developers appear in answers and others do not
Developers that get cited share an orderly public footprint. Their name, schemes and completed projects are described the same way on their site, in the French-speaking Swiss property press, on broker platforms and in public registers. Project pages are machine readable: real text rather than a PDF brochure, structured data, visible address and timeline.
Conversely, a developer stays invisible when its schemes only exist in brochures sent to brokers, when its visuals do not state that they are artist's impressions and not contractual, or when three sources give three different completion dates. Faced with conflicting information, an AI assistant often says nothing, or worse, summarises it wrongly.
Two sector constraints apply. Off-plan marketing must stay fair to the buyer: floor areas, finishes and timeline must not suggest more than what is contractual. And enquiry forms collect personal data covered by the revFADP, in force since 1 September 2023 under the supervision of the FDPIC, and by the GDPR if you target EU residents. This is not legal advice.
What this work covers and what it costs on the market
In broad terms, AI visibility work (often called AEO or GEO) covers: making public information about the developer and its schemes consistent, clear factual pages for each project and each completion, structured data, presence in serious third-party sources, freshness of information and tracking over time. It builds on classic SEO without replacing it.
| Market service | 2026 range (CHF, excl. VAT) | For whom | Note |
|---|---|---|---|
| One-off AI visibility diagnostic | 3,000 to 8,000 | Any developer wanting a baseline | Initial record of answers to 20 to 40 questions |
| Light monthly retainer | 3,000 to 5,000 a month | Developer with 1 or 2 active schemes | Tracking, corrections, factual content |
| Extended monthly retainer | 5,000 to 9,000 a month | Multi-scheme developer, FR and EN | Third-party sources, several languages |
| Property PR agency | 4,000 to 10,000 a month | Scheme launch | Useful but not measured on AI answers |
| Rebuild of project pages | 6,000 to 25,000 | Site built on PDFs | Often the most cost-effective first step |
2026 ballpark based on typical agency quotes in French-speaking Switzerland; the market is young and spreads are wide. At Kolonell, this work is priced on quote after a diagnostic. For reference, Kolonell built the website of Orven Properties, a real estate company in Dubai; we publish no figures about it.
How to measure it, and what to ask a provider
The only honest measure is a dated record: the same list of questions, asked at regular intervals, in French and English, with every answer archived. You track the share of answers that mention the developer, the accuracy of what is said (schemes, districts, dates) and the sources cited. Enquiries that mention an AI assistant as their starting point complete the picture.

Questions to ask any provider: which questions do you track and who chose them? How often is the record taken, and can I see the raw answers? What do you do when an AI assistant states something wrong about a scheme? And be wary of anyone who promises your name will be recommended: nobody controls what an AI assistant answers.
Mini case study
Illustrative example. Marc Dufour, sales director of "Lémanis Development", a developer of high-end residences on the left bank, orders a diagnostic at 5,000 CHF and then a 4,000 CHF a month retainer for 9 months. Total cost: 5,000 + 9 × 4,000 = 41,000 CHF. On a scheme of 14 apartments averaging 3.5 million CHF, avoiding a 2% brokerage fee on a single direct sale saves 70,000 CHF, 1.7 times the cost. The assumption still has to be tested: the record will show whether the developer appears more often, it does not guarantee the sale.
FAQ
Do luxury property buyers in Geneva really use AI assistants?
Increasingly for the scouting phase, especially international buyers who do not know local developers. On a record of 30 questions, you quickly see which names come up and which are missing.
How much does an AI visibility diagnostic cost?
In French-speaking Switzerland, 3,000 to 8,000 CHF for a one-off diagnostic, 2026 ballpark. At Kolonell, the diagnostic is priced on quote depending on the number of schemes and languages.
Should we stop classic SEO?
No: AI assistants partly rely on the same pages as search engines. A well structured project site serves both, and often accounts for 60 to 70% of the initial effort.
Are artist's impressions a problem?
They must be clearly presented as non-contractual. An AI assistant that describes a rendering as a completed building creates a reputational risk for the developer.
How soon does it have an effect?
Usually allow 3 to 6 months before a visible change in answers, depending on how often sources are updated. No serious provider promises a timeline or a recommendation.
