Signals, not a judgement: missing details are common on small, honest sites.

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.
We look for what AI site builders such as Lovable, Bolt and v0 leave in a page. Code written with an AI assistant such as Cursor, Claude Code or ChatGPT leaves nothing to find, so we can’t tell whether AI helped.
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 60 of 100.
It keeps 28 of 51 AI crawlers out, for training and for answers: 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 +12Sitemap +10
Optional: for sites with an API or a sign-in.
Below the median of the 2,439 most visited sites we read, which 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.petitesannonces.ch 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.
Sitemap
Now None found.
Publish an XML sitemap and list it in robots.txt.
Why it matters: A sitemap lists every page, so crawlers find the ones no link leads to.
Add an XML sitemap at https://www.petitesannonces.ch/sitemap.xml that lists the site’s public pages, in the sitemaps.org format, and add the line "Sitemap: https://www.petitesannonces.ch/sitemap.xml" to https://www.petitesannonces.ch/robots.txt. Generate it from the site’s routes, so new pages are added to it.
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.petitesannonces.ch 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.
llms.txt
Now None found.
Publish a short Markdown summary of the site at /llms.txt.
Why it matters: A short summary for AI models, at an address they can find. A proposal: few AI companies say they read it yet.
Create https://www.petitesannonces.ch/llms.txt as llmstxt.org describes it: a Markdown file with an H1 naming the site, a one-paragraph summary in a blockquote, and short sections listing its most useful pages as links, each with a line on what it holds. Serve it as text/plain or text/markdown.
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.petitesannonces.ch 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.petitesannonces.ch 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.

It gives no Content Signals and no “noai” tag.
Like 25% of the 973 popular sites whose robots.txt we’ve read since 29 Oct 2026, it keeps at least one AI training crawler out. Of the 1,193 popular sites we’ve checked since 29 Oct 2026, 9% have a page drawn by scripts, 4% send a Markdown copy, 10% have an llms.txt and 4% offer a file for AI agents. 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.
