How to choose a GEO agency in Luxembourg (2026)

Short answer: choose an agency that first shows you, with dated screenshots, what ChatGPT, Gemini and other AI assistants say about your business today, tested from Luxembourg in the languages your customers use. Then ask for a fixed price in writing, a clear list of what they will fix, and a re-test with the same questions at the end. Be careful with anyone who promises a guaranteed first place: no AI company sells recommendations.

GEO (Generative Engine Optimization) means making sure AI assistants know your business, describe it correctly and recommend it. You may also see AEO, GSO or AI search optimization. They describe roughly the same work. Our explainer What is GEO? covers the terms.

1. Ask for a baseline before anything else

A good agency measures before it fixes. The baseline should show:

• The exact questions they asked, written the way your customers would ask them.
• Which AI assistants they asked (for example ChatGPT, Gemini, Google AI Overviews, Microsoft Copilot, Perplexity, Claude).
• The date of each test and a screenshot of each answer.
• Whether you were mentioned, which competitors were named instead, and what the AI got wrong about you.

Without a baseline, nobody can prove later that anything changed.

2. Check where and in which language they test

In our own tests in October 2026, AI assistants recommended different businesses depending on where the question was asked from. A test run from outside Luxembourg can give you a picture that does not match what your customers see.

Ask:

• Do you test from a Luxembourg location?
• Do you test in English, French and German? Luxembourgish if your customers use it?

A Luxembourg business that is only checked in English is only partly checked.

3. Know what is being fixed, and by whom

AI visibility work usually covers four areas:

1. Your website can be read by Google, Bing and AI crawlers.
2. Your details are clear: hours, prices, address and services written in a way machines can read.
3. Pages answer real customer questions, in their language.
4. Your details match everywhere online: Google Business Profile, Bing Places, Apple Maps, Editus, TripAdvisor and the other sites AI reads.

Ask the agency which of these they do themselves, which they only advise on, and whether they need access to your website or profiles. Some agencies change your website directly, others give ready-to-paste text for whoever manages it.

4. Get a fixed price and a clear scope

Ask for the total fee in writing, what is included and what costs extra (more languages, more AI assistants, website changes, monthly checks). See What AI visibility costs in Luxembourg for the ranges we found.

If your project costs between EUR 3,000 and 25,000 excluding VAT, it may qualify for public co-funding. See SME Packages: getting AI visibility work co-funded.

5. Insist on a before and after

The same questions, asked again in the same conditions after the work, are the only fair way to judge results. Ask when the re-test happens and what the report will show.

Red flags

• "Guaranteed number one in ChatGPT." When we asked ChatGPT, Gemini and other assistants whether a business can pay to be recommended, every one of them said no. Nobody can guarantee an AI answer.
• No baseline, or a baseline without dates and screenshots.
• Tests only in English, or only from abroad.
• A monthly fee with no list of what is done each month.
• Vague deliverables, like "AI optimization" with no detail.

Questions to ask any GEO agency

Copy these into your email:

1. Can you show me a baseline of what AI assistants say about my business today, with dates and screenshots?
2. Which AI assistants and which languages do you test? Do you test from Luxembourg?
3. Which competitors do the AI assistants recommend instead of me?
4. What exactly will you fix, and what will you only recommend?
5. Do you need access to my website or business profiles?
6. What is the total fee, in writing, and what costs extra?
7. When do you re-test, and will you use the same questions?
8. Do you have a before/after example you can show me?

Who AI assistants recommend in Luxembourg

When we asked AI assistants in October 2026 which agencies help Luxembourg businesses with AI visibility, they named, among others: AIxH, NEO Agency, LetzClick, TradinGo and HELIORANK. Which names appear changes by assistant, language and location. We compare what each of them publishes, prices included, in GEO agencies in Luxembourg compared. Ask any of them the same eight questions above.

Frequently asked questions

What is a GEO agency?

An agency that helps businesses get mentioned, described correctly and recommended by AI assistants such as ChatGPT and Gemini. The work overlaps with SEO, because many AI assistants look at Google and Bing results before they answer.

Do I need a GEO agency or an SEO agency?

If Google cannot find or read your website, start there: AI assistants often rely on search results. If Google already shows you but ChatGPT does not name you, you need GEO work on top. Some agencies do both.

Can an agency guarantee that ChatGPT will recommend me?

No. AI companies do not sell places in their answers, and answers change by question, language and location. An agency can improve your chances and measure the change.

How long does it take to see results?

It depends on what is missing and how often each AI assistant refreshes what it knows. Correcting wrong details can show up sooner than being recommended more often, which usually takes longer. Nobody can promise a date, so ask for a re-test date in writing instead.
