The verdict in three sentences
For an M&A boutique in Luxembourg, Google SEO captures owners already searching for sell-side advice, while visibility in AI assistants like ChatGPT (AEO/GEO) matters when a founder, a family or a fund asks which Luxembourg M&A boutiques know their sector. Both rest on the same material: factual pages, real and announceable deals, named partners, published consistently in French, English and often German. On a limited budget, start with a shared diagnostic, then allocate according to what it reveals rather than to the trend of the moment.
Two levers, two clocks
The table compares both approaches for a Luxembourg boutique of 3 to 15 people. Amounts are a 2026 ballpark drawn from typical quotes by agencies in the Grand Duchy and the Greater Region.
| Criterion | SEO (Google) | AEO/GEO (AI assistants like ChatGPT) |
|---|---|---|
| What it targets | Queries such as sell my company advisor Luxembourg | Questions such as which M&A boutique to sell a financial services firm in Luxembourg? |
| Time to effect | 4 to 12 months depending on competition and languages | 2 to 6 months to correct errors, longer to be cited |
| Market budget | EUR 1,500 to 5,000 a month, audit EUR 2,500 to 8,000 | Diagnostic EUR 3,000 to 10,000, monitoring EUR 800 to 2,500 a month |
| Metrics | Impressions, clicks, qualified inquiries | Share of answers citing the boutique, accuracy, sources cited |
| Main risk | Generic content that never ranks | Contradictory information repeated by the AI |
| Effect of multilingualism | Each language is a separate query market | The AI cross-checks versions: an inconsistency shows |
One common point deserves emphasis: in both cases, tombstones are what persuade. Publish only real deals, already announced or whose announcement the parties have approved, with no deal value unless it is public. A boutique gains nothing by inventing a track record.
Which priority for your situation?
| Situation | Suggested priority | Why |
|---|---|---|
| Boutique founded less than 2 years ago | Shared foundations, then local SEO | Few third-party mentions; clear pages and named partners come first |
| Established brand, many announced deals | AEO/GEO first | The material exists; it needs to be consistent and readable by AI |
| Strong sector focus (funds, insurance, industry) | Both, with shared sector pages | AI and Google questions overlap on the sector |
| Regulated activity or content needing sign-off | Careful SEO, AEO limited to verified facts | Every sentence must pass compliance review |
| Budget under EUR 20,000 a year | Diagnostic, then a single lever | Spreading EUR 1,500 a month over two channels dilutes the effect |
| Cross-border clients (Lorraine, Saarland, Wallonia) | Multilingual SEO | Owners search in their own language, often German |
Depending on the activities carried out, a regulated status may apply to certain forms of financial advice; check this with your counsel before writing your service pages. This is not legal advice. On the website side, the GDPR applies and the CNPD is the competent Luxembourg authority: contact forms, newsletters and analytics tools must comply.
How each channel is measured
For SEO, Google Search Console gives impressions and clicks by page and by country; add the number of qualified inquiries (company size, deal type, horizon). For AEO/GEO, the measure is a dated record: the same 30 to 50 questions, asked every month on a fixed date in each relevant language, answers archived word for word. It shows the share of answers citing the boutique and the accuracy of what is said (sectors, partners, deals). No honest provider guarantees a Google position or an AI recommendation.
What a diagnostic covers
A serious diagnostic covers the technical state of the site, consistency of information across the site, professional profiles and directories, Google queries by language, a first record of AI answers and a costed recommendation on quote. It does not hand over a recipe: it tells you where to put the money.

Illustrative example: Moselle Ridge Partners, a fictional 4-partner boutique in Luxembourg, advises on sales of family businesses and fund services companies. Available annual budget: EUR 36,000. Option A, all SEO: EUR 6,000 audit then 12 months at EUR 2,500, so EUR 30,000, total EUR 36,000. Option B, split: shared diagnostic EUR 6,000, SEO at EUR 1,500 a month for 12 months (EUR 18,000) and AI monitoring at EUR 1,000 a month (EUR 12,000), total EUR 36,000. The diagnostic shows 5 answers out of 40 cite the boutique with a former partner: it picks option B, because fixing that error is quick and reaches owners already considering a sale.
FAQ
Does an M&A boutique really need both levers?
Not necessarily from the start. Below EUR 20,000 a year, a diagnostic followed by 12 months of focus on a single channel is often more effective.
Which languages should we publish in for Luxembourg?
French and English are almost always needed, German often for cross-border clients. Each added language raises writing costs, as a ballpark by 20 to 40% per version.
Can we show our deals without transaction values?
Yes, that is common: sector, deal type, year and the boutique's role are enough. Only public deals or deals whose announcement is approved should appear.
How long before a measurable result?
Allow 4 to 12 months for SEO depending on competition, and 2 to 6 months to see errors corrected in AI answers. A 12-month record lets you compare both channels.
Can a provider guarantee ChatGPT will cite us?
No. It can improve the consistency and accuracy of available information and measure, across 30 to 50 fixed questions, how the share of mentions evolves.
