What an AI crawler gets 0 words

Nothing. The HTML this page serves carries no readable main text, so a crawler that does not run JavaScript receives an empty page.

80% of this page's content never reaches an AI crawler.

159 words of the 200 a browser renders never reach an AI crawler. The chance to get cited by AI is very low to near zero.

Both panels are the main text of the same page, counted the same way and fetched twice at the same moment: once as an AI crawler asks for it, with no JavaScript, and once in a real browser. The panel with more text than fits opens to the full text. Text only one side has is highlighted.

Longest first. A passage counts as missing when its text appears nowhere in the HTML a crawler receives, so a block that merely moved is not listed. Lines under 4 words are not judged either way, because a match on "Get Started" would be chance rather than evidence.

Why a crawler does not get this, and the fix

When an AI crawler visits your page it receives a nearly empty shell, because your words only appear after a browser runs the site's code, which crawlers do not do.

The fix Server-side render or statically generate the page so the main content ships in the initial HTML.

Full impact and the evidence from your page

Where this score comes from

Four weighted parts, and the arithmetic is on the page. Nothing here is rounded in your favour, and anything the scan could not measure says so rather than being folded in as a guess.

AI crawlers see little of what your visitors see.

A critical issue is holding this page back. The grade above does not tell the whole story: start with the critical item below.

Part Weight Measured Points
Prose Parity 50% 0% 0
Crawler access 25% 100% 25
Structure 15% 46% 6.9
Structured data 10% 10% 1
0 + 25 + 6.9 + 1 32.9 Read the methodology

Retrievability, measured at 0%, sits beside the score rather than inside it: it checks whether the rendered words can be recovered from the crawler's HTML at all, including from JSON data blocks, and it informs the findings below without adding points.

This page scores higher than 4% of the 1,175 sites we have measured. That puts it in the bottom 10 percent. See the index.

Not indexed; share this link freely. Save it as a PDF with your browser's print (Cmd or Ctrl + P) for a client-ready copy.

This homepage is 47.1 points short of the 80 that unlocks a score badge. Do this first lists the quickest fixes; scan again once they are live.

See if AI recommends you

We ask one AI engine three questions a buyer would ask about your kind of business, and show you whether amsterdamumc.nl is named, who is named instead, and the sources it cites. Free, one per email.

We use the email only to send that one link and to keep it to one free check per address.

Your next move

Do this first

7 things are holding this page back. These are the 3 worth doing first, in order.

  1. Critical Main content is invisible to AI crawlers

    Server-side render or statically generate the page so the main content ships in the initial HTML.

    AI assistants cannot see what you sell or say, so when a buyer asks about your kind of business they get told about competitors whose pages are readable and you are left out entirely.

    See the evidence for this csr_blank

    up to +50

  2. Major Structured data is injected client-side only

    Your JSON-LD appears only after JavaScript runs, so AI crawlers never see it. Emit it in the initial HTML.

    AI crawlers capture the page before that summary appears, so your core facts never reach them and you go unmentioned.

    See the evidence for this client_injected_schema

    up to +9

  3. Minor No meta description in the initial HTML

    Add a server-rendered meta description.

    AI assistants are left to guess how to describe you and may summarize you inaccurately or favor a competitor whose page states its purpose clearly.

    See the evidence for this missing_meta_description

    +2.3

4 more findings below, ranked the same way.

Estimated gain is the sub-score arithmetic applied to this page, not a prediction about citations. Clearing the first item alone would move this page from 32.9 to at most 82.9.

Bot access matrix All 15 AI crawlers we track can reach this page

Every AI crawler we track, and what your site does when it asks for this page. Turning a model training crawler away is a choice, not a fault, so those are marked apart from the blocks that cost you score.

Every AI crawler in this list can reach this page.

  • 15 / 15 named crawler tokens allowed in robots.txt
  • 12 / 12 live probes got the page (HTTP 2xx)
  • 3 rule-only or not probed, so no server response to read

Reaching a page is not the same as reading it. The crawlers marked allowed here are let in and receive the same HTML a browser gets, but on this page that HTML is a near-empty shell until JavaScript runs. What they can actually read is scored separately: see Main content is invisible to AI crawlers below.

  • Reaches your page

    Your robots.txt allows this crawler and your server returned it the same page it returns to a browser. This measures access, not content: whether that HTML is readable without JavaScript is a separate check, scored as retrievability when the page can be graded.

  • Allowed

    Your robots.txt allows this token. It is a robots.txt token only: it sends no user agent of its own, so there is no server response to test and none is implied.

AI-readiness checklist 3 of 7 basics in place

The page basics an assistant needs, checked against what an AI crawler receives rather than the rendered page. These feed the Structure part of the score above.

  • Title tag The page has a title, which is the first thing an assistant names it by. Pass
  • Meta description No meta description. It is the summary an assistant may quote; add one under 155 characters. Needs work
  • One H1 heading Not exactly one H1. A crawler reads the page subject from its single H1; use one. Needs work
  • Canonical URL No canonical link. It tells a crawler which URL is the real one; add rel=canonical. Needs work
  • Heading coverage Headings cover the content, so a crawler can index it by section. Pass
  • No wall of text No single block is too long to parse cleanly. Pass
  • llms.txt No llms.txt. It is informational only, a nice-to-have rather than a ranking factor. Needs work
  • Structured data Found MedicalOrganization, Hospital, WebPage, but only after JavaScript ran, which a crawler may not see. Pass

What is holding you back, worst first

Ranked by severity, worst first. Start at the top: fix the critical items and the rest compounds.

Critical

Main content is invisible to AI crawlers

csr_blank up to +50

AI assistants cannot see what you sell or say, so when a buyer asks about your kind of business they get told about competitors whose pages are readable and you are left out entirely.

What this means for you

When an AI crawler visits your page it receives a nearly empty shell, because your words only appear after a browser runs the site's code, which crawlers do not do.

The fix, technically

Server-side render or statically generate the page so the main content ships in the initial HTML.

Evidence from your pageOnly 0% of the rendered main content exists in the initial HTML (200 rendered tokens vs 0 raw tokens).

Fix the rendering gap. We move the content AI engines miss into the initial HTML: server rendering, static generation, or hydration restructuring, measured before and after with this scanner.

Get a rendering audit
Major

Structured data is injected client-side only

client_injected_schema up to +9

AI crawlers capture the page before that summary appears, so your core facts never reach them and you go unmentioned.

What this means for you

The labeled summary of your key business facts is added only after your page finishes loading in a visitor's browser.

The fix, technically

Your JSON-LD appears only after JavaScript runs, so AI crawlers never see it. Emit it in the initial HTML.

Evidence from your pageJSON-LD appears in the rendered DOM but not in the initial HTML.

Ship structured data that parses. We add server-rendered JSON-LD with the required properties for your content types, validated by the same checker that graded this page.

Get schema implemented
Minor

No meta description in the initial HTML

missing_meta_description +2.3

AI assistants are left to guess how to describe you and may summarize you inaccurately or favor a competitor whose page states its purpose clearly.

What this means for you

Your page carries no short summary sentence describing what it is about.

The fix, technically

Add a server-rendered meta description.

Evidence from your pageNo meta description in the initial HTML.

Make the page extraction friendly. Titles, headings, and block structure decide how retrieval systems chunk and quote you. We restructure pages so the right passages surface.

Get a structure pass
Minor

Page does not have exactly one H1

h1_count +2.3

AI crawlers can misread the page's main subject, weakening how confidently they match it to the questions buyers actually ask.

What this means for you

Your page is missing a single clear main heading that says what it is about, or it has several competing ones.

The fix, technically

Use a single H1 stating what the page is about.

Evidence from your pageFound 0 H1 elements in the initial HTML.

Minor

No canonical URL in the initial HTML

missing_canonical +2.3

When the same content sits at more than one address, AI assistants may credit a duplicate instead of your real page, splitting or losing the visibility you have earned.

What this means for you

Your page does not tell AI crawlers which web address is the official one for this content.

The fix, technically

Add an absolute self-referencing canonical link.

Evidence from your pageNo canonical link in the initial HTML.

Minor

No llms.txt

no_llms_txt +1.2

A handful of assistants will read this file if it exists, so adding it gives you a small extra chance of being understood correctly at no cost, though most tools ignore it today.

What this means for you

Your site does not include the optional plain-text guide that some AI assistants look for to understand what your business is about.

The fix, technically

Informational only. Independent 2026 data (Ahrefs, SE Ranking, Google documentation) shows no measurable citation effect from llms.txt. It is checked because it costs nothing and some assistants read it, but it moves neither crawling nor ranking.

Evidence from your pageNo llms.txt at the site root.

Minor

URL redirects off the original domain

offsite_redirect

The scores here describe that other site, so your own page is not the one AI is reading about you.

What this means for you

The web address you entered sends visitors to a different website.

The fix, technically

The scanned URL redirects to a different domain; scores describe the final target.

Evidence from your pageamsterdamumc.nl redirected to www.amsterdamumc.nl (1 hop(s)).

Crawler-view structured data

Entity confidence

We parsed the JSON-LD in the HTML a no-JavaScript crawler receives and checked five properties of the identity it declares. This measures your markup, not any AI system's behavior: nobody outside those systems can observe what they do with a given property, so nothing here is a prediction. Scored separately from your 32.9/100 score.

0/100 Not declared No identity node in the HTML a crawler receives. 0 of 5 signals present
  • Identity declaredAn identity node exists in the rendered DOM but not in the HTML a crawler receives, so a crawler that does not run JavaScript gets nothing here. Emit the same JSON-LD in the initial HTML.
  • External identifiers (sameAs)Measured on the identity node, and no identity node was found. Declare one first, then add sameAs URLs to it.
  • Stable identifier (@id)Measured on the identity node, and no identity node was found. Declare one first, then give it an absolute @id.
  • Logo declaredMeasured on the identity node, and no identity node was found. Declare one first, then add logo as a full https URL.
  • Category declaredMeasured on the identity node, and no identity node was found. Declare one first, then state a category as a specific type, a standard industry code, or a resolvable additionalType URL.

Starting point for your identity block

Built from this scan: the URL we resolved, plus one property for each signal above that we did not find. Every REPLACE_ value is a placeholder, so edit them before you ship this. We do not guess names, logos, profile links or categories, so nothing here is invented. Your identity node exists in the rendered DOM but not in the HTML a crawler receives, so this belongs in the initial HTML your server sends, not in a script that writes it later. 

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "@id": "https://www.amsterdamumc.nl/#organization",
  "name": "REPLACE_WITH_YOUR_ORGANIZATION_NAME",
  "url": "https://www.amsterdamumc.nl/",
  "logo": "REPLACE_WITH_AN_ABSOLUTE_HTTPS_URL_TO_YOUR_LOGO",
  "sameAs": [
    "REPLACE_WITH_A_URL_THAT_IDENTIFIES_THE_SAME_ENTITY"
  ],
  "additionalType": "REPLACE_WITH_A_CATEGORY_URL_OR_DELETE_THIS_LINE"
}
</script>

What each signal measures, the weights, and the sample behind them: the methodology page.

llms.txt This site serves none

This site serves no llms.txt. Informational only. Independent 2026 data (Ahrefs, SE Ranking, Google documentation) shows no measurable citation effect from llms.txt. It is checked because it costs nothing and some assistants read it, but it moves neither crawling nor ranking.

Keywords and prompts

Derive the questions people ask AI assistants where this page could be the answer, scored by how much of each the page actually covers, then test whether a named model brings the brand up at all. The scan you are reading is free and anonymous; this check asks a real model live, so it asks for an email.
