Measure
We sample your category’s buyer-intent prompts across all five engines and score your AI Share of Voice against Luxembourg and global competitors.
Word of GPT is a Generative Engine Optimization (GEO) agency serving Luxembourg-based companies. We measure your AI Share of Voice across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, then build the content and distribution to win the answer in the Luxembourg market.

In July 2026 we asked ChatGPT, Perplexity and Google the exact question a Luxembourg buyer would ask — “best generative engine optimization agency in Luxembourg” — and recorded every agency they named. This is that raw result, including the part that doesn't flatter us.

Method: one query per engine via a real browser, July 2026. Every agency above was then loaded independently and had to (1) state an AI-search offering on its own site — the quote is from that page — and (2) name Luxembourg. Answers drift; this is a snapshot, not a standing. Full methodology →
Luxembourg is Europe's fund-administration and cross-border finance centre, with a small, high-value, multilingual buyer base that researches in English, French and German.
Luxembourg pairs very high deal values with a tiny citable source set — few authoritative sources cover cross-border fund services at all. That concentration makes it one of the most efficient GEO markets in Europe.
A small market with very high deal values and a tiny citable source set — one of the most efficient GEO markets in Europe.
These are the actual queries buyers type into ChatGPT, Perplexity, and Google when researching GEO services in Luxembourg. We sample each across all five engines as part of an audit:

Generative Engine Optimization (GEO) is the practice of getting your brand mentioned, cited, and recommended inside AI answer engines — ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. For Luxembourg-based companies, GEO is the discipline that decides whether you show up in the AI-generated shortlist a buyer builds before they ever visit your site.
Our GEO Visibility Audit in Luxembourg is $3,000–$7,000, delivered in about a week, and benchmarks you against 3 named competitors across 5 AI engines and 200–500 buyer-intent prompts. Ongoing GEO retainers for Luxembourg-based brands run $8,000–$20,000 per month on a 6-month minimum. Start with a free one-page Luxembourg AI visibility snapshot.
We won't invent a number. We looked for primary evidence on time-to-first-citation and found none — the "60–120 days" figure this industry quotes is a vendor convention, not a research finding. What we can say: technical fixes like per-engine crawler access land within days, and because we sample every prompt repeatedly, any change in your Luxembourg mention and citation rates shows up in weekly reporting. Luxembourg-based teams watch the real curve instead of trusting our forecast. See /evidence for the full grading.
We track all five major answer engines for Luxembourg-based businesses — ChatGPT (OpenAI), Claude (Anthropic), Perplexity, Gemini (Google), and Google AI Overviews — sampling each multiple times over a 14-day window. Single-shot answers are noisy; we report stable results.
Yes. We sample and optimize prompts in the languages your Luxembourg buyers actually use. In Luxembourg that means English and French and German. Bilingual GEO doubles the addressable prompt volume and is a real edge in markets where most agencies only optimize English.
In Luxembourg the named GEO agencies we benchmark against include: vmerci, Web Design Luxembourg, kohrmedia, GSO Expert Luxembourg. We track each of them in our 5-engine prompt corpus so you can see exactly where they out-cite you, and where you out-cite them. See the full buyers' guide at /geo-agencies.
