Business tools can stay listed after a site stops using them.
3 of 7 trust signals found on the home page.
Signals, not a judgement: missing details are common on small, honest sites.
A second opinion on its security setup: Mozilla’s HTTP Observatory grades the site when you open it. Ten checks before you buy · A signal looks wrong? Report it

What its robots.txt and robots tags ask of AI crawlers. Each crawler chooses whether to follow it.
Read from what the page says about itself; we haven’t checked whether it’s true.
No AI builder traces found.
Coding tools such as Cursor leave no traces, so this doesn’t mean a person made it.
AI traces: None found
AI site builders leave traces in the sites they make. We look for the traces of 53 of them and show every match with the line it came from, so you can check it yourself.
We test this on 2,275 sites whose makers we know, and publish what we get wrong.
How we test it · Every builder we know · How to tell if a site was built with AI
AI can find it and read it: it scores 74 of 100.
It lets every AI crawler in: the site’s choice, never scored.
AI readiness
Its words are in the HTML, with a title and a description.
To reach AI-friendly:Structured data +12
Optional: for sites with an API or a sign-in.
Higher than 52% of the 2,439 most visited sites we read, whose median is 72.
Structured data
Now None found.
Add schema.org structured data, as JSON-LD, to the home page’s HTML.
Why it matters: Structured data tells AI tools and search engines what the site is: a company, a shop, a product.
Add schema.org structured data to the home page of https://www.2ememain.be as JSON-LD, in a <script type="application/ld+json"> tag in its HTML: an Organization with its name, url, logo and sameAs links to its official profiles, and a WebSite with its name and url. Add the type that fits what the site offers too, such as Product, Article or LocalBusiness. Use only facts that are true of the site.
Files for AI agents
Now None of the 8 we look for.
If agents could use the site, publish what they need where they look.
Why it matters: Agents act for people: they look for these files to know what a site lets them do. Worth it only if agents can use the site.
If AI agents could use https://www.2ememain.be for its visitors (to search it, book, buy or sign in), publish what they need at the standard addresses, and only what the site really offers: an MCP server card at /.well-known/mcp/server-card.json if it runs an MCP server, an API catalog at /.well-known/api-catalog (RFC 9727) listing its public APIs, and OAuth protected resource metadata at /.well-known/oauth-protected-resource (RFC 9728) if agents sign in.
Links for AI tools
Now None in the home page’s headers.
Point AI tools to the site’s files in the home page’s Link header.
Why it matters: A Link header points AI tools to a site’s files from any page, without guessing addresses.
Make the home page of https://www.2ememain.be send a Link header (RFC 8288) that points AI tools to the site’s files, for example: Link: </sitemap.xml>; rel="sitemap", </llms.txt>; rel="describedby"; type="text/plain". List only files the site serves.
Markdown copy
Now Not offered: it sends the page’s HTML.
Answer requests for Markdown with a Markdown version of the page.
Why it matters: A Markdown copy gives AI tools the page’s words without the HTML around them.
When a request to https://www.2ememain.be asks for Markdown (its Accept header includes text/markdown), answer with a Markdown version of the page’s main content and the header Content-Type: text/markdown. Requests for HTML keep getting HTML; add Vary: Accept so caches keep the two apart.

Keeping AI out is the site’s choice, so it never lowers the score.
Its robots.txt names none of the 24 crawlers of the 10 AI companies we know, so it lets every one in.
None of the 27 other AI crawlers we know is kept out.
It gives no Content Signals and no “noai” tag.
Like 68% of the 1,691 popular sites whose robots.txt we read in October 2026, it keeps no AI training crawler out. How many websites block AI crawlers?
We read the site once, as our named bot: its robots.txt, read as crawlers read it, its home page and the files AI tools ask sites for. What we couldn’t read says so. robots.txt asks and doesn’t enforce: a firewall can treat AI crawlers differently from us.
89 of 100: strong trust signals.
How established and checkable it is; AI traces carry no weight.
A high score isn’t a promise that a business is honest. How the score works.
