AIR-1.1 Can AI crawlers reach your site? PASS 5 pt
Why we test this

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
What's half-done

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
Why we test this

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
What's wrong

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 241-character comment, too thin to read as a policy statement. NEEDS WORK +0
What's half-done

robots.txt carries a 241-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
Why we test this

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
Why we test this

88% of sampled pages emit a valid, self-consistent canonical. 4 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? PASS 2 pt
Why we test this

79% of sampled pages carry one main element, a wrapping article or section, and a nav. 6 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?58% of sampled pages have exactly one non-empty h1 and no skipped heading levels. 5 have no h1; 2 have several; 8 skip a level. NEEDS WORK +1
What's half-done

58% of sampled pages have exactly one non-empty h1 and no skipped heading levels. 5 have no h1; 2 have several; 8 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
What's wrong

/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?31 of 43 entity nodes carry an @id (72%). The WebPage to WebSite to Organization chain is broken at WebPage->WebSite, WebSite->Organization. 2 duplicate definitions of Organization. NEEDS WORK +1
What's half-done

31 of 43 entity nodes carry an @id (72%). The WebPage to WebSite to Organization chain is broken at WebPage->WebSite, WebSite->Organization. 2 duplicate definitions of 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?11 sameAs links: 0 tier-1 authority identifiers, 3 tier-2, 8 social. NEEDS WORK +1
What's half-done

11 sameAs links: 0 tier-1 authority identifiers, 3 tier-2, 8 social.

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?2 of 7 organizational facts are present in the Organization markup: address, contactPoint. PROBLEM +1
What's wrong

2 of 7 organizational facts are present in the Organization markup: address, contactPoint.

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
Why we test this

Raw HTML contains 84% of rendered text on average across 32 URLs. The worst template is /programs/*: 0% across 1 pages.

AIR-2.2 Progressive disclosure content ships in the initial HTML0 of 32 pages ship every disclosure panel populated in the raw HTML. 2 pages load more content on scroll with no paginated fallback. PROBLEM +2
What's wrong

AIR-2.3 Real data tables with header cells53 tables: 0 complete, 0 without scope on header cells, 43 with no header cells, 10 used for layout. PROBLEM +2
What's wrong

53 tables: 0 complete, 0 without scope on header cells, 43 with no header cells, 10 used for layout.

AIR-2.4 Stable, human-readable anchor IDs on section headings3 of 1095 subheadings carry a slug-like id (0%); 244 have generated or unstable ids. NEEDS WORK +1
What's half-done

3 of 1095 subheadings carry a slug-like id (0%); 244 have generated or unstable ids.

AIR-2.5 Alt text on content images, empty alt on decorative PASS 1 pt
Why we test this

Basis
public-interest census: a declared bot with a published policy at https://readinessindex.io/bot, honoring robots.txt addressed to AIRBot, reading public pages only. No per-site permission was sought or given.

The hash is the SHA-256 of the full result.json, recorded when the scan finished rather than computed now. The raw evidence behind every line above — every response, cached — is retained and is a median 1.5 MB per site, so it is not served from here. Ask us for it if you want to check a number against the bytes it came from.

Think this is wrong? It might be. Tell us at hello@readinessindex.io and we will look, correct it if it is, and say so publicly either way.

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.
