kayak.com
This is how AI agents (not browsers) experience kayak.com. The score weights five categories of machine-readability; the ticks on the arc are the 31 individual checks behind it.
Top fixes
No HTTP Link: response headers. Emit canonical/alternate/describedby relations so HEAD-only or stream-rendering agents get them without parsing HTML.
Fix: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.
Visible text is 1.2% of HTML weight (19241/1539725 bytes). Low. Markup may be crowding out agent-usable text.
Fix: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.
Browser pass unavailable; HTML looks like a JS-shell (e.g. #__next / #root). Likely JS-dependent.
Fix: Server-render or statically pre-render your primary content so non-JS agents receive it in the initial HTML.
1 recommended-field warning(s). First: Organization recommends "logo" (improves agent comprehension). 1 block(s) skipped — type outside the set we check.
Fix: Validate your JSON-LD with Google Rich Results test. Fix missing required properties.
Heading issues: 2 skipped level(s).
Fix: Use a single H1 and avoid skipping heading levels (H1 → H3).
<html lang="en-us"> is not a well-formed BCP 47 tag. The usual culprits: an underscore instead of a hyphen (en_US), a bare country code (UK), or a language name (english). Use language[-Script][-REGION]: en, de-DE, zh-Hans-CN.
Fix: Add `lang` to your `<html>` element (`<html lang="en">`, `<html lang="de-DE">`). If you publish translations, declare them with `<link rel="alternate" hreflang="..." href="...">` using BCP 47 tags — language[-Script][-REGION], hyphens not underscores.

This scan shows whether an agent can read the site. One free probe asks a real assistant a real buying question and records who it cited.
This graded your homepage. Your pricing, docs, and checkout live on other pages — the ones assistants actually quote when they recommend you — and a 73/100 here means agents are already missing things on the page you polish most. The $29 Deep Scan audits the whole site against all 31 checks, then emails a PDF with every failing check and its exact fix, ranked by what costs you the most visibility. One-time, delivered in minutes, no subscription.
Right now, only you know this score. Your buyers ask AI before they buy — certification is how you show them, and anyone comparing you to a competitor, that assistants can actually read, quote, and use your site.
- A public verification URL you can drop into a sales deck, a procurement questionnaire, or a partner review — anyone can check it, dated and signed.
- An embeddable badge for your site — the visible version of a property competitors can’t claim without earning the score.
- Weekly re-checks for a full year. A deploy that breaks agent access gets caught before it costs you recommendations — and before the certificate would lapse.
Sites under 70 can’t buy this at any price — that’s what makes displaying it mean something.

Get this report by email, then a heads-up when kayak.com’s agent-readiness actually changes — a check regressing, or the composite dropping.
Two things never trigger an email: a score change caused by us publishing a new rubric, because that is a different instrument rather than a change to your site, and movement explained only by timing-derived checks, which shift run to run on a site nobody touched.
Want it on your own schedule, with Slack or a webhook instead of email? Score-drift monitoring is on every paid plan.
This score says whether an AI agent could read kayak.com. AI traffic analytics says whether one actually came — and which pages turned it away.
