The verdict in three sentences
For a commercial real estate advisory in Luxembourg, mandates are still won through networks and reputation, but the heads of real estate, CFOs and investors preparing a move to Kirchberg or an acquisition at Cloche d'Or now ask their first questions to AI assistants like ChatGPT, in English, French or German. Classic SEO here costs EUR 1,500 to 6,000 a month (2026 ballpark), AEO/GEO work EUR 1,200 to 5,000 a month or a one-time diagnostic, with a real premium for multilingual coverage. The right balance depends on your situation; no serious provider promises that an AI will recommend you, but every one of them should be able to measure what it says about you, on fixed dates.
What occupiers and investors in Luxembourg ask AI assistants
The market is small, international and highly concentrated. A fund manager looking for 2,000 sq m near the station, a bank considering Belval for its back office, a Belgian family office studying an office building in Howald: all of them compare quickly. Their questions to AI assistants look like this, often in English even from French speakers:
- which commercial real estate advisers represent tenants in Kirchberg, and what are prime office rents in 2026;
- how to compare Cloche d'Or, Gare and Ban de Gasperich for a 150-desk headquarters;
- which firm publishes reliable market research on offices and logistics in the Grand Duchy;
- who advises foreign investors on an office acquisition, tax aside;
- which advisers speak German and Luxembourgish for a local landlord.
Answers draw on what is published and consistent: team pages, dated research, real listings, transactions made public, mentions in the business press. A firm whose research only exists as unindexed PDFs, or whose German pages are empty, is unlikely to be cited accurately. Real estate intermediation is framed by business permit rules and anti-money laundering duties, and any collection of contact data falls under the GDPR, supervised by the CNPD: stay precise about your status. This is not legal advice.
SEO and AEO/GEO compared for a Luxembourg advisory
| Criterion | SEO (Google) | AEO/GEO (AI answers) | Luxembourg specifics |
|---|---|---|---|
| Target | Queries like offices to let Kirchberg, firm name, research | Accurate mention of the firm in answers to tenant and investor questions | Queries split across 3 or 4 languages |
| Time to effect | 4 to 8 months | Often 2 to 6 months after public content is corrected | Low volume, every page counts |
| Market budget, 2026 ballpark | EUR 1,500 to 6,000 a month | EUR 1,200 to 5,000 a month, diagnostic EUR 2,000 to 7,000 | Multilingual: more effort per tracked language |
| Metrics | Search Console clicks, viewing requests, mandate enquiries | Share of tracked questions where you are cited, accuracy of figures repeated | Measure language by language |
| Risks | Outdated listings still indexed, invisible research | Wrong rents or floor areas repeated by AI | Confusion with Belgian or French firms of similar name |
Where to invest first, by situation
| Situation | Priority | Reason |
|---|---|---|
| New firm or new Luxembourg office | SEO first, AEO baseline in parallel | Without indexable pages, no AI can describe you |
| Known brand, regular market research | AEO/GEO first | Your research is what AI answers quote: check that it is cited |
| Sensitive content (confidential deals, exclusive mandates) | Internal review before anything | Publish only what is public and approved by the client |
| Limited budget, under EUR 2,000 a month | Team pages, research in HTML, current listings; quarterly AI record | The same content serves Google and AI answers |
| Mostly German-speaking clients or Anglo-Saxon investors | Measure per language before deciding | Visibility varies widely from one language to another |
| Recent merger or name change | Fast AEO diagnostic | AI answers often repeat the old name for months |
How to measure, and what a diagnostic covers
SEO is tracked in Search Console and your CRM: impressions on the firm name and district queries, viewing requests, inbound mandate enquiries. AEO/GEO is measured with a dated record: the same list of questions, asked to AI assistants at fixed intervals, each answer archived and scored. Here is what one page of that record looks like.
| Date | Tracked question | Language | Firm cited? | Accuracy |
|---|---|---|---|---|
| 6 January 2026 | Advisers for office tenants in Kirchberg | FR | No | Not applicable |
| 6 January 2026 | Commercial real estate advisers Luxembourg office market | EN | Yes | Prime rent quoted from 2023 |
| 6 January 2026 | Gewerbeimmobilien Berater Luxemburg | DE | No | Not applicable |
| 6 April 2026 | Advisers for office tenants in Kirchberg | FR | Yes | Correct |
| 6 April 2026 | Commercial real estate advisers Luxembourg office market | EN | Yes | Correct |
A diagnostic covers how AI assistants currently describe the firm in your working languages, which competitors are cited and the sources behind their presence, errors about your team, research or listings, and the state of your pages for both search and AI answers.

Mini case study
Illustrative example, fictional firm. Moselle Workspace Advisory, twelve consultants between Gare and Kirchberg, spends EUR 4,000 a month on digital, so EUR 48,000 a year, split into EUR 2,500 for SEO and EUR 1,500 for AEO/GEO. The baseline record covers 40 questions, 10 per language in French, English, German and Luxembourgish: the firm is cited in 6 answers, or 15 %, two of them with an outdated prime rent. If digital brings 16 qualified mandate enquiries a year, the cost per enquiry is 48,000 / 16 = EUR 3,000, to compare with the fee on a single office leasing mandate.
FAQ
Do we have to choose between SEO and AEO/GEO?
Rarely, since AI answers draw heavily on content that Google indexes. In Luxembourg, many advisories put 60 to 70 % of the budget into SEO and the rest into measuring and correcting AI answers.
How much does AEO/GEO cost for a commercial real estate advisory in Luxembourg?
Typical agency quotes sit around EUR 1,200 to 5,000 a month, or EUR 2,000 to 7,000 for a one-time diagnostic, depending on the number of languages tracked. At Kolonell, the scope is priced on quote.
How long before a measurable effect?
Often 2 to 6 months after public information is corrected, as shown in the dated record. SEO usually needs 4 to 8 months on competitive queries.
Should we track all four of the country's languages?
Tracking at least English, French and German covers most tenants and investors. Luxembourgish matters mainly for local landlords and credibility, with fewer questions asked.
Can an agency make sure ChatGPT recommends us?
No, nobody controls what an AI assistant answers. The work makes your public description more accurate and consistent, and the dated record shows the trend over 3, 6 and 12 months.
