The verdict in three sentences
For an executive search firm in Zurich, SEO remains the channel that brings candidates and a share of mandates, while AEO/GEO (visibility in the answers of AI assistants like ChatGPT) increasingly shapes the shortlist that board chairs and HR heads draw up before the first call. An established firm with a known name should usually start with AEO, because AI assistants already describe its business, sometimes wrongly; a newer firm must first build solid pages that both Google and AI assistants can cite. Either way, the decision rests on dated measurement: qualified leads for SEO, a record of AI answers to the same questions for AEO.
Two audiences, two ways of searching
The client of a Zurich headhunter is a board chair, a CEO or an HR head at an industrial group, a private bank or a scale-up. They rarely type "headhunter Zurich" into Google and increasingly ask an AI assistant: "which executive search firms in Zurich know life sciences and work in German and English?". They then judge practice areas, partner seniority, method and confidentiality.
The candidate still uses Google in the classic way: "Executive Search Zürich Finance Mandate", "submit CV executive search Zurich". They want to know which mandates are open and how their file will be handled. On data, the revised Federal Act on Data Protection (revFADP, in force since 1 September 2023), supervised by the FDPIC, requires clear information on the purpose and retention period of CVs; the GDPR may also apply when the firm targets EU residents. This is not legal advice.
SEO and AEO/GEO compared for a Zurich firm
| Criterion | SEO (Google) | AEO/GEO (AI assistants like ChatGPT) |
|---|---|---|
| Main audience | Candidates, some clients actively searching | Boards, CEOs, HR heads at shortlist stage |
| What is targeted | Practice pages, mandates, partner profiles in DE/EN | Accurate description of the firm in answers, third-party citations |
| Time to effect | 4 to 9 months depending on competition | 3 to 6 months to see answers move, with no certainty |
| Market budget (2026 ballpark) | CHF 2,000 to 6,000 a month, audit CHF 4,000 to 12,000 | CHF 2,500 to 7,000 a month, diagnostic CHF 3,000 to 9,000 |
| Metrics | Impressions, clicks, CVs received, mandate enquiries | Share of answers citing the firm, accuracy, sources cited |
| Main risk | Candidate traffic without client mandates | Young market, providers who overpromise |
These ranges reflect typical quotes from Swiss and European agencies; AEO being an emerging market, gaps between providers are wide. No serious provider promises a ranking on Google or a recommendation by an AI assistant.
Where to invest depending on your situation
| Firm's situation | Suggested priority | Why |
|---|---|---|
| New firm, two or three partners | SEO first, light AEO base | AI assistants have almost nothing to cite: factual pages come first |
| Established brand, international footprint | AEO first | AI assistants already talk about the firm, the issue is accuracy and completeness |
| Narrow practice (boards, CFOs, pharma) | Both, content by practice | Questions are precise and the pages serve both channels |
| Sensitive content (pay, confidential mandates) | Cautious AEO, partner review | An AI assistant can repeat information out of context |
| Limited budget, under CHF 3,000 a month | AEO diagnostic then targeted SEO | Knowing what AI assistants say avoids investing blind |
| Offices in Geneva and Zurich | Bilingual FR/DE SEO, AEO in English | Candidates search locally, boards often ask in English |
The common ground: factual pages per practice and per partner, with no invented placements or client names, serve both Google and AI assistants. What differs is how you measure.
How results are measured, and what a diagnostic covers
For SEO, measurement runs through Google Search Console (impressions and clicks by page and language) and above all through business results: mandate enquiries received, qualified CVs for open mandates. A report that shows only positions with no link to leads does not support a decision.
For AEO, the only honest measure is a dated record of answers: the same list of 20 to 40 questions put to AI assistants like ChatGPT at regular intervals, in German, English and sometimes French. You note whether the firm is cited, what is said (practices, partners, offices), errors and the sources mentioned. The record is compared month to month; it does not explain why an assistant changes its answer, but it shows the trend.
A serious diagnostic covers, in broad terms: the state of the firm's public pages, consistency of information across directories and press, a first record of AI answers, a Search Console review and a costed recommendation on the SEO/AEO split. It does not hand over a recipe; it informs an investment decision.

Mini case study
Illustrative example: Stauffer & Keller Partners, a four-partner Zurich firm focused on CFO and board searches. Annual visibility budget: CHF 48,000. The initial record shows the firm in 3 answers out of 30 questions put to AI assistants, with one practice described wrongly. Chosen split: 60% AEO (CHF 28,800), 40% SEO (CHF 19,200). If SEO brings 2 extra mandate enquiries a year, with average fees of 33% of a CHF 270,000 package, about CHF 89,100 per mandate, a single signed search covers almost twice the annual budget. The AEO goal is measured separately: moving from 3 to 9 answers that cite the firm correctly on the same 30 questions within twelve months, with no guarantee.
FAQ
Should we stop SEO to fund AEO?
In most cases, no. Candidates keep searching on Google, and pages built for SEO also serve as sources for AI assistants; a 60/40 split one way or the other is more common than a full switch.
How long before AI answers change?
Allow 3 to 6 months to see movement in a dated record, with no certainty. AI assistants update at different paces and no provider controls their answers.
Can we mention completed placements on the website?
Only with written consent from the client and the candidate, and in factual terms. Many Zurich firms prefer to describe types of mandates (for example CFO of a listed company with 2,000 staff) without naming anyone.
What is the minimum budget to start?
A standalone diagnostic sits around CHF 3,000 to 9,000 (2026 ballpark). Below CHF 2,000 a month, it is better to concentrate on a single channel.
Do we need content in German, English and French?
In Zurich, German and English are the minimum; French becomes useful if the firm has an office or clients in Romandy. Each added language increases the number of pages to maintain by about a third.
