How much does AI search optimisation cost with HENUSSE?
A first year has three lines: the AI Citation Diagnostic at €1,500 excl. VAT, the AEO Foundation billed once, from €5,000 to €12,000 excl. VAT as a package depending on the condition of your website, excluding additional treated pages, and the monthly programme, from €1,500 to €10,000 excl. VAT per month. The three complete budgets below range from €23,000 to €56,800 excl. VAT for the first year, at the Essential and Authority tiers, the lowest of the three being a floor. At the Sovereignty tier, the programme alone costs €120,000 excl. VAT over twelve months.
Pricing details
Three monthly programmes, prices excluding VAT: Essential at €1,500, Authority at €3,500 and Sovereignty at €10,000. The AI Citation Diagnostic costs €1,500 excl. VAT and is deducted from the programme or AEO Foundation that follows, once, within twelve months. An optional named-competitor comparison adds €400 excl. VAT per competitor, up to four. AI search optimisation is also known as AEO or GEO. The Diagnostic measures what ChatGPT, Claude and Gemini say about your company today; the AEO Foundation then brings your website up to standard; the monthly programme publishes.
All prices published on this page exclude VAT and have been in effect since 5 August 2026.

The total
What a first year costs
On an already healthy website, AEO setup only and the Essential tier cost €23,000 excl. VAT, at the published floor.
On a website that needs rebuilding, the rebuild and the Authority tier cost €56,800 excl. VAT.
On a website that needs building, the build and the Essential tier cost €29,500 excl. VAT.
Each total is calculated line by line below. These prices have been in effect since 5 August 2026.
Order matters
What you pay, in three lines
An AI search optimisation invoice has three lines, and they arrive in this order. The Diagnostic measures where you stand. The AEO Foundation brings your website up to standard, once. The monthly programme then publishes and measures over time.
01
Diagnostic
We measure what ChatGPT, Claude and Gemini say about your company today, question by question. It costs €1,500 excl. VAT and is deducted once from the invoice that follows, within twelve months.
02
AEO Foundation
We rebuild the code, structure and copy that carry your offer before adding more editorial volume. It is billed once, from €5,000 to €12,000 excl. VAT depending on your situation, and comes before the first programme month.
03
Article programme
We then build authority, question by question, on a clear and coherent website. It costs €1,500, €3,500 or €10,000 excl. VAT per month depending on the tier.
The three entry points to the AEO Foundation
| Your situation | What is included | One-off, excl. VAT |
|---|---|---|
| 1. Website build | Up to five pages in scope, including AEO rewriting from your material | €11,500 |
| 2. Existing-site rebuild | Up to eight pages in scope, including rewriting | €12,000 |
| 3. AEO setup only | On an already healthy website, without rewriting | from €5,000 |
| One additional page in scope | For both a build and a rebuild | €1,400 |
These prices exclude VAT and have been in effect since 5 August 2026. A page in scope is a page that we build from your material or rewrite, including its AEO copy and structured data: this is the unit we charge for. Two legal pages and one authority page are included and are not counted. With AEO setup only, where nothing is rewritten, the unit becomes the equipped template, together with unique pages outside any counted template.
The details of each situation, what you provide, what we build and the special cases are on the dedicated page: see the AEO Foundation price.
An authority article cannot make up for a weak website. We put the AEO Foundation right first: the code, the structure and, above all, what your website says about you. Then the articles build authority.
The Diagnostic and measurement
Know where you stand, then measure without embellishment
The AI Citation Diagnostic costs €1,500 excl. VAT and is deducted from the programme or AEO Foundation that follows, once, within twelve months. Its conclusion may be that you should not proceed. The full example of a delivered diagnostic is public, reading taken from 7 to 8 August 2026, 270 AI answers analysed, raw answers included: you know exactly what you are buying.
Citations come last. We lead with what we have built and the first signals. Every reading is dated and also counts absences. A reading is a snapshot, not an established performance.
The total, written down
Three first-year budgets, calculated in front of you
A quotation is not a pricing table; it is an addition. Here are three situations calculated line by line using the prices published on this page and the Foundation page. Yours will resemble one of them, and your quotation will name your own pages.
In all three cases, the Diagnostic is deducted once, in full, from the invoice that follows. It therefore does not add to the total when you proceed: your first-year total is the same with or without it. If its conclusion is that you should not proceed, you will have paid €1,500 excl. VAT, and nothing else.
Budget 1
Your website is healthy, but machines cannot read it yet
Your website stands on its own: it already meets SEO and AEO standards, with all four PageSpeed scores above 90.
First-year total
€23,000 excl. VAT
AI Citation Diagnostic
€1,500
AEO Foundation, setup only, at the published floor

€18,000
These prices exclude VAT and have been in effect since 5 August 2026.
The calculation, line by line
The assumptions
- Your website stands on its own: it already meets SEO and AEO standards, with all four PageSpeed scores above 90. We verify this before confirming this budget.
- No page is rewritten. The setup covers author pages, structured data and the article publication channel. As soon as one decisive page needs rewriting, budget 2 applies: the €1,400 per-page price covers pages treated beyond a package or within a programme, never a way to stay in this budget.
- AEO setup only is counted at its published floor. The exact amount depends on the number of equipped templates and unique pages outside any series, and is written in the quotation.
- You choose the Essential tier, with one anchored article per month, in French only.

When you pay what
You pay €5,000 excl. VAT before the first month, including and deducting the Diagnostic, then €1,500 excl. VAT per month for twelve months. The payment schedule is written in the quotation.
What is not included

- Webmastering is a separate line, from €300 excl. VAT per month.
- The English version of the programme costs an additional €490 excl. VAT per month at the Essential tier.
- Off-site authority costs €2,500 excl. VAT, once.
- A comparative analysis of a named competitor costs €400 excl. VAT per competitor, up to four.
The most requested variation
With the Authority tier instead of Essential, replace €18,000 with €42,000: the first-year total becomes €47,000 excl. VAT.
Budget 2
Your website has existed for years, and it has lived
You have ten decisive pages, excluding legal pages.

The calculation, line by line
The assumptions
- You have ten decisive pages, excluding legal pages. The rebuild package covers eight, and the next two cost €1,400 excl. VAT each.
- Your positioning is settled: you know what you sell, to whom and on what terms. If that remains to be decided, add €3,000 excl. VAT.
- You provide your images.
- You choose the Authority tier, with four anchored articles per month, in French only.

What is not included
- Positioning and brand strategy cost €3,000 excl. VAT, once, if nothing has yet been settled.
- Visual identity and graphic design cost €3,000 excl. VAT. Together, they cost €5,000 excl. VAT.

The most requested variation
If the website remains in French and the programme also publishes its articles in English, the bilingual option at the Authority tier costs €1,190 excl. VAT per month, or €14,280 over twelve months: the first-year total becomes €71,080 excl. VAT. Translation of your existing website is quoted separately, page by page.
Budget 3
You do not have a website yet
You do not have a website, or you have one page that says nothing about what you do.

The calculation, line by line
The assumptions
- You do not have a website, or you have one page that says nothing about what you do.
- Your material exists: your offers are settled, and your copy and images are available. We rewrite them for AEO; we do not write the substance on your behalf.
- Your visual identity exists and we apply it to the pages. If it needs designing, add €3,000 excl. VAT.
- We work on five pages: most often Home, About, Contact and two offer pages. Two legal pages and one authority page are added without being counted.
- You choose the Essential tier, with one anchored article per month, in French only.

- The presentation film and its page cost €4,000 excl. VAT.
- Webmastering is a separate line, from €300 excl. VAT per month.
- Drafting your legal terms is not our role: we build the pages, and you provide or approve the legal copy.
The most requested variation
With the visual identity to design, add €3,000 excl. VAT: the first-year total becomes €32,500 excl. VAT.
What none of these three budgets includes
- Hosting and the domain name remain in your name and at your expense.
- The licences you choose remain at your expense: fonts, image libraries and extensions.
- Fees charged by paid third-party sources are paid directly by you, never advanced or rebilled by us.
All prices are stated exclusive of tax. Each provider invoices their own work directly: Théo’s invoices are issued from France and currently fall under the French VAT exemption for small businesses; if VAT becomes applicable to him, it is added to the agreed prices. Nicole’s invoices are issued from Belgium: for a VAT-registered business in France, they fall under reverse charge, as with any European supplier, without changing the price excluding tax.
The second year
The second year includes neither a Diagnostic nor a Foundation. It costs twelve months of the programme: €18,000 excl. VAT at the Essential tier, €42,000 excl. VAT at the Authority tier and €120,000 excl. VAT at the Sovereignty tier, at prices in effect since 5 August 2026.
None of these three budgets is your quotation. The quotation counts the pages in your project, names them one by one and applies the prices published here: an addition, written before anything begins.
The three programmes
The three-tier pricing table, and what each tier includes
An anchored article is an article published under your name, linked to your pages and your evidence, written to become the answer an AI can cite. A citation reading is the dated list of the questions put to the AI systems and of what they answered. Authority is the recommended tier: it combines four anchored articles per month, dated citation readings and an advisory call. An example of an anchored article, published by us, can be read in full on realfrench.co: Why Can I Read French But Not Understand It Spoken?.
These prices exclude VAT and have been in effect since 5 August 2026. Each amount covers a precise scope, written on this page, which the scoping phase then fine-tunes with you for your project.
| Scope | Essential €1,500 per month excl. VAT | Authority €3,500 per month excl. VAT Recommended tier | Sovereignty €10,000 per month excl. VAT |
|---|---|---|---|
| Anchored articles | 1 per month | 4 per month | 5 to 6 per month |
| Drafted LinkedIn post, one per article, ready to publish under your name | Not included | included | included |
| Authority pages created and maintained each year | 1 | 3 | 5 to 6 |
| Bilingual version | French + English: option +€490 per month excl. VAT | French + English: option +€1,190 per month excl. VAT (instead of €1,960 for four articles) | included (two or three languages) |
| Multilingual option | The multilingual option includes translating your content and measuring the same questions, asked in each language. | ||
| Maintenance of the technical side: the markup that explains your pages to AI systems, the structure of the website, and AI crawler access (controlled by robots.txt, complemented by llms.txt, which we maintain for tidiness: Google stated in 2025 that it does not use it, and it is not what drives visibility) | included, after the AEO Foundation | + corpus enrichment, the library of your verified sources | + a database linking your products, your people and your references to one another |
| Content updates | Not included | included | included |
| Regulatory monitoring | Not included | alert + updates to key pages | proactive + committee |
| Market exclusivity | Not included | optional: €700 excl. VAT per month, using the Sovereignty-tier definitions | yes (one Sovereignty client per market: the activity, the clientele and the territory, set cumulatively in the written quotation; languages and tracked questions define the mission’s scope) |
| Targeted social presence | Not included | Not included | yes (in the spaces where the answer takes shape, always introducing ourselves as your provider, never posing as you) |
| Commitment | 12-month minimum | 12-month minimum | 12 to 24 months |
| Citation measurement and reporting | weekly reading, quarterly report | weekly reading, monthly report | weekly reading, monthly report + committee |

Pricing table details
Here are the measurement details.
Measurement details
We track 10 fixed questions at the Essential tier, 15 at the Authority tier and 30 at the Sovereignty tier. In French and English, this number doubles to 20, 30 and 60 questions.
Each question is put to the three engines, ChatGPT, Claude and Gemini, through their official tools, with three repetitions per question because their answers vary from one run to the next. The exact surface and model are named on every reading, as Why these three and not Perplexity, Mistral or Grok: the panel’s scope, with dated figures.the charter requires: this is what makes the measurement honest rather than anecdotal.
All tiers include dated citation readings, and every article is submitted to you before publication: nothing goes live without you having had the chance to say no.
The drafted LinkedIn post comes with each article because LinkedIn is among the sources answer engines display on professional questions. In our 26 August 2026 reading, LinkedIn pages appear in the results pages of our own panel. We draft the post, you publish it under your name, and we never hold your credentials.
The quantities on this line are the number of authority pages the programme creates and maintains each year. They are included in the monthly price of each tier and are in addition to the authority page included in the AEO Foundation, which is invoiced once before the programme. An authority page establishes who is speaking: the named expert, their verifiable credentials and structured markup, linked to the content they sign.
The AI Citation Diagnostic costs €1,500 excl. VAT and is deducted from the programme or AEO Foundation that follows, once, within twelve months.
The AEO Foundation, through a website build, an existing-site rebuild or AEO setup only, comes before the article programme. Its three prices appear above on this page, and three first-year budgets add them to the monthly programme. The details of each situation are on the Foundation page. Here is what the monthly programme covers, and what it does not.
Covered by the monthly programme
- We produce the articles of the tier you have chosen.
- We maintain the technical side put in place during the AEO Foundation.
Not covered by the monthly programme
- The AEO Foundation is not included in the monthly fee: it is charged once, before the first month.
- We do not carry out the initial technical setup: that work belongs to the AEO Foundation.
- We do not build the website and we do not rewrite it: those tasks belong to the AEO Foundation too.
For an online shop, write to us: the scope is defined case by case.
The minimum commitment is 12 months: enough time for the research, publication and measurement to produce evidence that can be assessed. The exact duration and exit terms are set out in the written quotation. The exit itself is not a negotiation: our stopping rule is public, and if our own readings trigger the written recommendation to stop, it opens an exit at thirty days’ notice, before the end of the term. The rule in plain words.
Our approach to pricing
The prices are published. You know them before you write to us.
What the programme includes
Work that the engines can recognise
The programme combines a model of your voice, verified sources, authority pages, links and structured data.
- ✓ a model of your voice (not generic copy)
- ✓ a corpus of citations verified against the source
- ✓ authority pages for your authors
- ✓ cross-referencing, a presence in the spaces where the answer takes shape (included at the Sovereignty tier; elsewhere an option, with off-site authority)
- ✓ rich structured data, implemented and validated
- ✓ maintenance of the existing technical setup: structure, structured data and llms.txt, within the scope of your tier
No per-article price
You buy the programme, not a quantity of copy
An article designed to become an answer that AI can cite is not a blog post: its price covers research, verification, grounding in your voice, publication, technical work and measurement.
What changes a quotation
What changes the price, and where to verify it
The price does not depend on the age of your website. It depends on the surface we work on and what we rewrite.
Five things change the Foundation: the number of pages in scope beyond the package, at €1,400 excl. VAT each; the number of equipped templates for setup only; series of similar pages, such as product sheets, which are handled as a series rather than individually; languages; and extraction from a locked platform when necessary.
For the website, the first added language costs €700 excl. VAT per page in scope. Each subsequent language costs €550 excl. VAT per page in scope. For the monthly programme, French and English cost an additional €490 excl. VAT per month at the Essential tier and €1,190 excl. VAT per month at the Authority tier. Multilingual delivery is included at the Sovereignty tier, up to two or three languages depending on the order form.
Four things change the monthly programme: the tier you choose, the bilingual version, market exclusivity and off-site authority.
Every unit that can appear on a quotation is published on the complete price list, versioned and dated, with prices in effect since 5 August 2026. Is your situation outside the standard cases? See our special cases. The details of the three Foundation situations are on the Foundation page.
The other written prices
This page calculates AI search optimisation. For training, a two-hour session costs €450 excl. VAT, a three-and-a-half-hour half-day costs €800 excl. VAT, a full day costs €1,400 excl. VAT. These prices have been in effect since 5 August 2026. Read the training details.
This option is distinct from the monthly programme and the AEO Foundation.
Off-site authority
AI search optimisation does not stop at your website. Answer engines also weigh what third-party sources say about you: the press, professional directories, reference sites in your industry and partners. This option builds that presence, with one simple rule: relevance and quality, never volume.
The price is public.
The foundation costs €2,500 excl. VAT, once. Campaigns are then quoted on request, and you pay the budgets for paid sources directly to the source. At the Sovereignty tier, off-site authority is included in the price, with an update every quarter.
How it works
Here is how it works.
01
We provide you with a foundation report, a map of the sources that matter in your industry and all the materials ready to use.
02
You approve the sources you want to activate.
03
We make contact and handle every detail transparently, as your AI search optimisation provider.
04
You pay only for paid sources, directly to the source.
We do not buy links in bulk. A paid mention makes sense only when the source is relevant and genuinely cited by AI systems. Any fees charged by third-party sites are paid directly by you; we never advance or rebill them. We contact sources openly as your provider, never by pretending to be you.
Why it matters
The cost of being present in the way your buyers search
This is not a three-month return on investment. It is your presence in the way your buyers search today. For the years ahead, we build; we do not promise.
01
The instant answer
AI answers from memory, based on what it has learnt. What it will retain tomorrow cannot be measured today.
02
Web search
When AI searches the web and cites sources, your content needs to be findable and citable straight away, meaning clear enough and sourced well enough for an AI to take it as its own answer.
03
Training over the years
Your content may become part of the training data for future models. No one can measure or promise this. We do not sell it or charge for it.
Questions from business leaders
Frequently asked questions about AI search pricing
How much does the first year cost in total?
Three complete budgets are written on this page, with their assumptions and calculations. On an already healthy website, with AEO setup only and the Essential tier, the first year costs €23,000 excl. VAT at the published floor. On a website with ten decisive pages that needs rebuilding, with the Authority tier, it costs €56,800 excl. VAT. On a five-page website that needs building, with the Essential tier, it costs €29,500 excl. VAT. These prices exclude VAT and have been in effect since 5 August 2026.
Is the website included in the monthly price?
No. The monthly programme produces the articles and maintains the existing technical setup. It does not build the website, rewrite it or install the technical layer at the outset: those three tasks belong to the AEO Foundation, which is billed once before the first month.
Does the Diagnostic cost extra?
It costs €1,500 excl. VAT and is deducted once, in full, from the invoice that follows, whether Foundation or programme, within twelve months. If you proceed, it therefore does not change your first-year total. If its conclusion is that you should not proceed, you will have paid €1,500 excl. VAT, and nothing else.
How much does AI search optimisation cost with HENUSSE?
The monthly programme has three fixed tiers: Essential at €1,500 per month, Authority at €3,500 per month and Sovereignty at €10,000 per month, all excluding VAT. The AI Citation Diagnostic costs €1,500 excl. VAT and is deducted from the programme or AEO Foundation that follows, once, within twelve months. The AEO Foundation is billed once before the first month, from €5,000 to €12,000 excl. VAT as a package depending on the condition of your website, excluding additional treated pages. A complete first year ranges from €23,000 to €56,800 excl. VAT across the three situations written on this page. These prices exclude VAT and have been in effect since 5 August 2026.
Why be cited for general questions, rather than only when someone is looking for a provider?
Because the purchase question comes last. Your buyers ask substantive questions first, and the engine retains those who answer them with evidence. When the question that prompts a decision arrives (which provider to choose), it draws on sources it already knows. Covering the questions in your field builds the authority that makes you eligible for the commercial answer. It is a probability built one question at a time.
Why does the commitment last 12 to 24 months?
The programme builds an editorial, technical and verifiable presence over time. The minimum commitment is 12 months for Essential and Authority, and 12 to 24 months for Sovereignty. This is not a one-off purchase of copy.
Can I buy a single article?
No. HENUSSE sells a monthly programme, never a per-article price. Research, verification, grounding in your voice, publication, technical work and measurement form a single body of work.
Does the Authority tier promise citations?
No. No tier promises a citation, ranking or result. ChatGPT, Claude and Gemini retain the decision. The Authority tier is recommended because it establishes a monthly rhythm of work and measurement, not because it promises an outcome.
How is the measurement presented?
Every reading is dated, its scope is declared and the results are shown as fractions. If the measurement returns zero, the report states zero. A reading remains a snapshot, never an established performance.
Are the prices negotiable?
No. Prices and scopes are those of the published price list: a higher quotation than someone else’s carries more units, never a different rate.
Who owns the content, and what do you keep if you leave?
Your content belongs to you. The articles, authority pages and structured data we produce are published on your site, in your name, and remain your property. If you leave, you keep everything: the site, the content and the markup. Nothing is withheld, nothing is locked, and everything is reversible.
There are only two of you. Is that a risk for me?
There are two of us, Théo and Nicole Hénusse, and that is a choice. You work directly with the people who do the work, with no intermediary, and we deliberately limit the number of engagements we take on so that each one receives our full attention. Above all, you are never trapped with us. Everything belongs to you: your site, your hosting, your domain name, your articles and their copyright, and your infrastructure. We can give you a clear schematic of your setup. We keep only our own tools, which we do not open up, but they do not lock you in. If you stop working with us, you keep everything, and another provider can take over. A large agency can keep its know-how in a black box. With us, what matters stays with you.
The starting point
Choose a tier only after reviewing the ground.
The 30-minute call starts with your market and your questions. It does not commit you to any programme.
