The verdict in three sentences
For an international tax and fiduciary firm in Amsterdam, SEO still captures most of the measurable demand: executives who type precise queries such as 'transfer pricing Amsterdam' or 'trust office Netherlands substance'. AEO/GEO, meaning being cited accurately when a founder asks AI assistants like ChatGPT which firms handle a Dutch holding restructuring, now shapes the shortlist before anyone visits your site. For most established firms the sound decision is to keep SEO as the base and fund a smaller AI visibility audit, measured with a dated record of AI answers to the same questions.
Who searches, who asks AI, and what they want to know
Clients of an Amsterdam tax and fiduciary practice are not browsing. They arrive with a dated problem: a holding relocation, a transfer pricing review, a CRS or FATCA filing, an estate spanning three jurisdictions. Their journey now mixes Google and AI assistants, with different phrasing on each channel.
| Client profile | Typical Google query | Typical question to an AI assistant | What they check next |
|---|---|---|---|
| Founder relocating a holding | 'relocate holding Netherlands tax adviser' | 'Which Amsterdam firms help move a holding and what does substance mean?' | Partners, jurisdictions covered |
| Family with assets in several countries | 'trust administration Amsterdam' | 'Is a Dutch trust office licensed, and by whom?' | Licence, discretion |
| Group CFO | 'transfer pricing documentation Netherlands' | 'What should a transfer pricing file for a Dutch BV include in 2026?' | Sector experience |
| Fund manager | 'fund administration Amsterdam CRS FATCA' | 'Who handles CRS and FATCA reporting for a Dutch fund vehicle?' | Reporting capability |
| Expat executive | 'expat tax adviser Amsterdam' | 'What does the Dutch expat tax regime change for me?' | Fees, language |
| Investment deal team | 'tax due diligence Amsterdam' | 'Which advisers run tax due diligence on a Dutch target?' | Team, public references |
Two things follow. Google queries are short and technical: one well built service page per issue (substance, transfer pricing, trust administration, CRS/FATCA reporting) often ranks on modest but highly qualified volumes. Questions put to AI assistants are long and comparative: they ask for firm names, selection criteria, sometimes a view on regulation. Your firm appears or not depending on what the web says about you consistently: your site, professional directories, articles signed by your partners, mentions in the specialist press.
SEO or AEO/GEO: the comparison for an Amsterdam tax firm
| Criterion | SEO | AEO/GEO (AI visibility) |
|---|---|---|
| What it targets | Google positions for precise service queries | Being cited and described correctly in answers from AI assistants like ChatGPT |
| Time to first effect | 3 to 6 months on niche pages, 6 to 12 months on contested queries | A few weeks to a few months, with answers that shift week to week |
| Market budget (2026 ballpark) | EUR 1,500 to 5,000 a month with a specialist B2B provider | One-off audit EUR 2,500 to 7,000, follow-up EUR 800 to 2,500 a month |
| Main metrics | Impressions, clicks, positions in Search Console, qualified enquiries | Citation rate on a question panel, accuracy of the description, sources cited |
| Risks | Generic content that attracts off-target private individuals | Wrong description of your licences or jurisdictions, which you cannot edit directly |
| What matters most | Pages per issue, partner profiles, insight articles | Consistent public information, authority of third-party sources, clear pages |
These ranges reflect typical agency quotes and public rate pages seen on the Dutch and wider European market. They move with the number of languages (Dutch and English at minimum, often more for an international client base) and with the state of your current site. No serious provider promises a ranking on Google or a recommendation by an AI: they promise work, a calendar and measurement.
Where to put the money, by situation
| Firm situation | Budget priority | Why | Watch out for |
|---|---|---|---|
| New firm, few indexed pages | SEO first, about 80% of budget | Without clear pages, AI assistants have nothing reliable to cite | Publishing ten generic articles in one month |
| Established brand, known partners | 60/40 split between SEO and AEO | Your name already circulates; check how AI describes it | Partner profiles up to date on every source |
| Regulated activity (trust office, financial firm) | Early AEO audit, then SEO | An AI that gets your licence wrong is a reputation risk | Compliance review before publishing |
| Limited budget, under EUR 2,000 a month | Focused SEO on 3 to 5 service pages | Return is more measurable in the short term | One AI audit a year is enough |
| Opening a new jurisdiction | Both, in parallel | New Google queries and comparative AI questions | Announce only what is actually operational |
| Strong English content, nothing in Dutch | Multilingual SEO | Part of local executives search in Dutch | Translation reviewed by a tax professional |
A word on regulation, kept general. In the Netherlands trust offices operate under a licence from De Nederlandsche Bank (DNB), the AFM supervises financial market participants, and the Autoriteit Persoonsgegevens enforces the AVG, the Dutch name for the GDPR. Your site, contact forms and insight content should stay consistent with that framework: no promised tax outcome, nothing that reads like avoidance, minimal data collection and a secure contact channel. This is not legal advice.
How to measure, and what a diagnostic covers
SEO is measured with tools your partners can open themselves: Search Console for impressions and clicks per page, site analytics for journeys, and above all your CRM for qualified enquiries per service. A monthly report that does not connect service pages to inbound enquiries is an activity report, not a measure of results.
AEO is measured differently. You fix a panel of 20 to 40 questions that represent your clients, in Dutch, English and your clients' other languages, then record on fixed dates how AI assistants answer those same questions: is your firm cited, in what position, with what description, based on which sources. Repeated every quarter, that dated record shows a trend, while a single screenshot proves nothing.

A serious diagnostic covers, in broad terms, the state of your service pages, the consistency of public information about the firm (licences, partners, jurisdictions), presence in the third-party sources AI assistants rely on, a first record of answers on your question panel, and a costed recommendation on how to split budget between the two levers.
Mini case study
Illustrative example: Keizer Fiduciary Partners, six partners on the Zuidas, has an annual visibility budget of EUR 48,000. The firm spends EUR 3,000 a month on SEO, so EUR 36,000, for six service pages in Dutch and English. It funds an initial AEO audit at EUR 4,500 and three quarterly records at EUR 2,500 each, so EUR 7,500, for an AEO total of EUR 12,000. Total: 36,000 + 12,000 = EUR 48,000. If an administration mandate brings in EUR 25,000 in annual fees on average, two new mandates, EUR 50,000, cover the year's spend. The example assumes no result: it sets the break-even point before you sign.
FAQ
Should we stop SEO to fund AI visibility?
Not for most firms. AI assistants rely partly on well indexed, well structured pages, and Google still drives a large share of measurable enquiries. A split around 70/30 or 60/40 in favour of SEO is common for an established brand.
How much does an AI visibility audit cost in Amsterdam in 2026?
Typical quotes sit between EUR 2,500 and 7,000 for a one-off audit, depending on the number of languages and questions tested. Quarterly follow-up often adds EUR 800 to 2,500 a month on the market.
How soon will we see an effect?
Allow 3 to 6 months for niche service pages on Google, longer on contested queries. AI answers can move within weeks but stay unstable, which is why a dated record over at least two quarters matters.
Can an AI assistant misdescribe our licence or jurisdictions?
Yes, and it is a real risk for a regulated firm. You cannot correct an AI directly: you make public information consistent on your site and third-party sources, then check the change at the next record.
What should we ask a provider?
Ask how they measure (Search Console, CRM, dated question panel), who reviews tax content, and how often you receive the records. Be wary of any offer that announces a ranking or a recommendation by an AI.
