AIR-1.1 Can AI crawlers reach your site? PASS 5 pt
All 10 AI agents may fetch content paths.
Your robots.txt file tells crawlers what they may read. A line left behind by a previous site or a copied template can quietly shut out the assistants people now use to find you.
AIR-1.2 Does your CDN let AI crawlers through?1 of 8 AI user-agents are rejected or challenged at the edge. NEEDS WORK +2
1 of 8 AI user-agents are rejected or challenged at the edge.
Even when robots.txt says yes, a firewall or bot-protection rule can turn assistants away before they reach your pages. We sent a request as each one and recorded what came back.
AIR-1.3 Is your page readable without a security challenge? PASS 1 pt
No interactive challenges on 32 sampled read-only pages.
A CAPTCHA or bot check on an ordinary page stops an assistant at the door. These belong on forms and logins, not on pages anyone can read.
AIR-1.4 Have you stated what AI may do with your content?No Content-Signal line in robots.txt. Missing: search, ai-input, ai-train. PROBLEM +3
No Content-Signal line in robots.txt. Missing: search, ai-input, ai-train.
There is now a machine-readable way to say whether AI may search, quote or train on your material. Having a position — any position — is the point.
AIR-1.5 Can a person read your AI policy?robots.txt carries no human-readable policy statement. PROBLEM +1
robots.txt carries no human-readable policy statement.
A few plain sentences in robots.txt saying what you permit. Journalists and lawyers read this file, and right now most sites say nothing.
AIR-1.6 Are you allowing assistants to quote you? PASS 1 pt
No noarchive, nosnippet or max-snippet:0 directives found.
Some sites carry old settings that tell search engines not to show excerpts. Those same settings stop an assistant quoting your page in an answer.
AIR-1.7 Does this page declare its real address?3% of sampled pages emit a valid, self-consistent canonical. 31 have problems. PROBLEM +1
3% of sampled pages emit a valid, self-consistent canonical. 31 have problems.
A canonical link tells a machine which URL is the true one. Without it the same content can be treated as several competing pages.
AIR-1.8 Is your page structured so a machine can follow it?3% of sampled pages carry one main element, a wrapping article or section, and a nav. 16 exceed 12 divs per semantic element. PROBLEM +1
3% of sampled pages carry one main element, a wrapping article or section, and a nav. 16 exceed 12 divs per semantic element.
Meaningful sections rather than an undifferentiated wall of containers. It is the difference between a document and a soup of boxes.
AIR-1.9 Do your headings tell a clear story? PASS 2 pt
97% of sampled pages have exactly one non-empty h1 and no skipped heading levels. 1 skip a level.
One main heading, then sub-headings in order. Assistants use headings to work out what a page is about and which part answers a question.
AIR-1.10 Do you publish a guide for AI assistants?/llms.txt returns HTTP 404. PROBLEM +2
/llms.txt returns HTTP 404.
A file at /llms.txt listing your most important pages. It is early and cheap, and it forces a useful conversation about what actually matters on your site.
AIR-1.11 Can a machine tell what your organization is?30 of 52 entity nodes carry an @id (58%). The WebPage to WebSite to Organization chain is broken at WebSite->Organization. NEEDS WORK +1
30 of 52 entity nodes carry an @id (58%). The WebPage to WebSite to Organization chain is broken at WebSite->Organization.
Structured data that links together — your organization, your site, this page — rather than a scattering of disconnected labels.
AIR-1.12 Can a machine be certain it is you?No sameAs links were found on Organization or Person nodes. PROBLEM +2
No sameAs links were found on Organization or Person nodes.
Links from your markup to authoritative records like Wikidata or ROR. Without one, an assistant is guessing which organization of your name it has found.
AIR-1.13 Can a machine find out who you are?0 of 7 organizational facts are present in the Organization markup: none. PROBLEM +2
0 of 7 organizational facts are present in the Organization markup: none.
Founding date, leadership, address, contact details, legal identifiers. Thin About pages are the most common weakness we see.
AIR-2.1 Primary content is present without JavaScript PASS 5 pt
Raw HTML contains 82% of rendered text on average across 31 URLs. The worst template is /culture: 1% across 1 pages. 1 URLs were excluded from the mean.
AIR-2.2 Progressive disclosure content ships in the initial HTML0 of 32 pages ship every disclosure panel populated in the raw HTML. 30 pages load more content on scroll with no paginated fallback. PROBLEM +2
0 of 32 pages ship every disclosure panel populated in the raw HTML. 30 pages load more content on scroll with no paginated fallback.
AIR-2.4 Stable, human-readable anchor IDs on section headings0 of 177 subheadings carry a slug-like id (0%); 0 have generated or unstable ids. PROBLEM +2
0 of 177 subheadings carry a slug-like id (0%); 0 have generated or unstable ids.
AIR-2.5 Alt text on content images, empty alt on decorative PASS 1 pt
372 of 381 images carry appropriate alt text: 0 have no alt attribute, 0 use the filename.
AIR-2.6 Key facts exist as HTML text, not only in images or PDFs32 of 32 sampled pages are thin relative to their images or lead with a document download. PROBLEM +1
32 of 32 sampled pages are thin relative to their images or lead with a document download.
AIR-3.1 JSON-LD is generated from mapped fields, not hardcoded3 of 3 templates repeat identical schema literals across pages whose visible content differs. PROBLEM +2
3 of 3 templates repeat identical schema literals across pages whose visible content differs.
AIR-3.2 BreadcrumbList on every page below the homepage66% of pages below the homepage carry a BreadcrumbList with at least two steps. NEEDS WORK +1
66% of pages below the homepage carry a BreadcrumbList with at least two steps.
AIR-3.5 isAccessibleForFree, about, and mentions with entity references0 of 9 substantive pages declare isAccessibleForFree; 0 reference subject entities by identifier. PROBLEM +1
0 of 9 substantive pages declare isAccessibleForFree; 0 reference subject entities by identifier.
AIR-3.7 SearchAction on the WebSite nodeThe SearchAction template returns 53 characters of results for a test term. NEEDS WORK +0
The SearchAction template returns 53 characters of results for a test term.
AIR-3.8 Schema validation of the structured data on the page PASS 2 pt
199 nodes across 32 pages parse, carry what their types require, and hold well-formed values.
AIR-4.4 Correct X-Robots-Tag on non-HTML resources0 of 14 non-HTML resources carry an X-Robots-Tag. PROBLEM +1
AIR-4.5 Missing pages return 404 or 4100 of 5 deliberately invalid URLs returned HTTP 200; 8 sampled pages are thin enough to be not-found templates. NEEDS WORK +0
0 of 5 deliberately invalid URLs returned HTTP 200; 8 sampled pages are thin enough to be not-found templates.

Is your site ready for AI?
Scan a page, get a number you can verify. Free.
About these numbers. Points are whole numbers everywhere on this page. The arithmetic behind them is not — a test scores its weight times its band divided by four, so a row can earn 1.5 points and print as 2. Scores are computed from the exact figures and rounded once, at the end, never from the rounded rows. That means adding the points column up will not give you the score exactly. The rule is published in the standard.
