What Google and AI engines see of your site
You give your address. We read your home page the way an engine reads it, and tell you what is missing.

What Google and AI engines see of your site
A search engine does not read your page the way you do. It looks for precise markers: a title, a summary sentence, a main heading, a declared identity record, a file telling robots what they may read. When a marker is missing, it does not guess — it moves on.
Language models came later. They look for extra markers that most sites never laid down, because those markers did not exist when the site was built. That is where the gap opens up, and it is what nobody has measured for you yet.
Give me your address. I read your home page the way an engine reads it, and I hand you back the list, in plain language.
One single public request to your home page, exactly like a visitor. Nothing is changed, nothing is stored, and the address appears in no log.
Resolving the domain…
The 27 checks
And the rest
These points were recorded on your page. Their detail was not sent to your browser.
What needs fixing
Each line matches a fault found on your page. How to fix it is not part of this demo.
Where to start
What was not analysed
Everything above concerns a single page, read once, with nothing executed. Here are the ten areas a full audit covers and this one did not touch.
And the full audit?
What you have just seen runs in fifteen seconds on one page. The same work across an entire site — every page, real-world speed, the structured data to write, the llms.txt to generate — is what I do for my clients, and it is not something a public page can do.
Request a full audit of my siteHow it is built
The code measures, the model translates. The 27 checks and the secondary signals are computed in PHP, on your page’s source code. Opening that source and counting by hand gives exactly the same result. The score is computed too: each check carries a weight, and the weights add up to a hundred. The language model only steps in afterwards, and for one thing only — saying in plain language what each gap produces. It can neither invent a fault, nor erase one, nor touch the score.
Your address is written nowhere. No log contains the address you typed, the domain, or the result. What is kept on the server is limited to processing time and the number of failed checks, with nothing that could lead back to you. The result lives in your tab and disappears with it.
One public request, read-only. Your home page is requested exactly as a visitor requests it, with the robot explicitly identified. Nothing is sent, nothing is changed, no private page is reached. The address is checked before the call — protocol, port, name resolution, the server’s real address — and every redirect is re-checked the same way.
What it does not do. One page, once, without executing JavaScript. A site whose content is built in the browser will look empty, and that in itself is a finding. Neither real-world speed, nor the other pages, nor the editorial content is judged here.
Who built this
My name is Nicolas Baier. I have been writing code since 2005, on my own, with no imposed framework or CMS, building the tools companies cannot buy off the shelf: business applications, internal portals, automations.
This page is not a product. It is a demo module, built to show a mechanism. Yours would be wired to your own documents, your own vocabulary and your own rules.

Frequently asked questions
What exactly does the test measure?
Twenty-seven checks across four families: what Google displays, what AI engines read, what the page is worth, what the visitor sees. Everything is measured by code; the model only turns the readings into plain language, it scores nothing itself.
Is my website address kept?
No. The server makes a single public read-only request to your home page, exactly like a visitor. Nothing is changed, and the address you type is written to no log.
Why is my score low?
The scale is dated 2026: the “what AI engines read” family is worth 40 points out of 100. A site that is fine for Google can be invisible to ChatGPT or Perplexity — which is exactly what the test brings out.
What do I do with a bad score?
The detail lists every failed check, in order of points lost. For the fix — technical, content and visibility in answer engines: SEO & AI visibility.
Does the test work on every site?
On any public home page over HTTPS or HTTP. Internal addresses, bare IPs and private hosts are refused, and the read is capped: the tool observes, it does not load your server.
Does this module speak to you?
Tell me in two lines what you would want it to do at your company. I reply within 24 hours, with no sales follow-up.
Or, more simply: fifteen minutes on the phone.
