Making your company readable by AI. Outside, and in. AI search optimisation (GEO/AEO) · The decision stage
Are you cited by AI systems? The answer, in black and white.
Your buyers ask ChatGPT, Claude or Gemini their questions. The AI Citation Diagnostic shows you, question by question, whether these engines cite your company. You receive a dated report, a summary written by a human and a clear verdict: proceed, make corrections first, wait, or buy nothing.
It is a paid service because the answer is honest: if your company is already cited frequently, the report will say so, and the verdict may be to buy nothing from us.

What the Diagnostic contains
Evidence, an assessment and a decision.
01
Your buyers’ real questions
The Diagnostic starts from the questions your buyers actually ask: we write them with you, then fix and date them before the first test. They do not change once measurement starts, in accordance with the Honest Measurement Charter.
02
Dated answers from the engines
The reading covers 30 buyer questions, frozen before the first measurement, each put 3 times to ChatGPT, Claude and Gemini: 270 answers read one by one. You see clearly how many questions your company is cited for and which sources the engines used. When you do not appear, that is recorded as such: we do not disguise zero results. The full answers are retained.
The multi-surface reading answers another method question: is a brand cited in the same way across answer surfaces? It publishes the protocol, the results and their limits.
03
Your website assessment
The website assessment establishes what your website currently allows the engines to understand about your company, and what they lack in order to cite you. Here too, anything missing is recorded as such.
04
The decision note
The decision note brings together a signed summary and one of four verdicts: proceed, make corrections first, wait, or buy nothing. It is a clear document that you can share with your business partners as it stands.
A Diagnostic does not end with a list of fifty recommendations. It ends with three actions, ranked by expected effect, each stating what it costs, what it may change and how we will know whether it worked. The rest goes into an appendix for those who want every detail. A list of fifty points is a way of prioritising nothing.
See before you buy: the full audit and the off-site audit are client deliverables published in full. This is the same type of document you will receive, with your data. realfrench.co is a genuine client business: the school belongs to the Henusse family, and HENUSSE serves it. We say this so you can judge the evidence knowing the connection.
What comes next
Monthly programmes are decided after measurement.
If the verdict is to proceed, the next stage is built in two parts: first bring your website up to standard, then publish content every month that the engines can cite, while regularly measuring the results. Each programme is set out in a signed written quotation, with the scope and amount detailed before any decision. Nothing is commissioned on this page.
Direct questions, straight answers
Questions about the Diagnostic.
Do you promise that my company will be cited by answer engines?
No. No one controls what ChatGPT, Claude or Gemini decide to cite. We commit to the work, method and measurement, never to a citation. We also refuse success fees: they would encourage us to choose questions that suit us rather than the ones your buyers ask.
Do you need access to our systems?
Not for the Diagnostic: we look at what is public, exactly as the engines do. If work follows, it may require temporary administrator access, removed on delivery. Publication then uses a plugin that you install and can remove. If you also entrust us with the role of webmaster, a separate and optional service, only the access credentials named in the dedicated annex are retained.
Do you train artificial intelligence systems to cite us?
No. We make your website clear and readable for the engines that come to it for answers, when you allow them to. Over 12 to 24 months, some content may also feed future models. That is possible, but no one can measure or promise it, so we do not sell it or charge for it.
How much does AI search optimisation cost with HENUSSE?
All our prices are public. 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 monthly programme prices are public: Essential at €1,500, Authority at €3,500 and Sovereignty at €10,000 per month, all excl. VAT. The AEO Foundation, whether a website build, existing-site rebuild or AEO setup only, has its own page and public prices. Each engagement is then covered by a signed written quotation and purchase order, with its scope set out in writing before any decision.
Which answer engines do you measure?
ChatGPT, Claude and Gemini. For each question, you see which engine was queried, on which day, and how many times your company was cited out of the number of attempts, in plain terms. We claim nothing beyond what we have actually measured.
Can the Diagnostic conclude that we should not proceed?
Yes. It is one of the four verdicts, and we give it when it is the right decision for you. The fee is not a disguised deposit: it is the price of an honest answer, even when that answer is to buy nothing from us.
