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? PASS 5 pt
All 8 AI user-agents receive full content.
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 a 433-character comment, too thin to read as a policy statement. NEEDS WORK +0
robots.txt carries a 433-character comment, too thin to read as a 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? PASS 2 pt
100% of sampled pages emit a valid, self-consistent canonical.
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? PASS 2 pt
84% of sampled pages carry one main element, a wrapping article or section, and a nav. 5 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
75% of sampled pages have exactly one non-empty h1 and no skipped heading levels. 3 have no h1; 6 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.

2 sameAs links: 0 tier-1 authority identifiers, 1 tier-2, 1 social.

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.
