Can AI assistants read jku.at?

Measured on 2026-09-19 by asking the site 5 times — once as a browser, once as each of the 4 crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Meta AI, Apple Intelligence and Doubao — and comparing what came back. The AI-training opt-out tokens that never crawl are read from robots.txt instead.

B77 / 100
2 of 4 crawlers can read this page.
More readable than 57% of the 47,935 sites measured so far. Structured data: WebSite, BreadcrumbList.

What each crawler got back

a robots.txt token, not a crawler: it controls how already-crawled pages may be used, and never makes a request of its own

What to change, in order

  1. Publish llms.txt
    llms.txt is missing, so an assistant has to discover the site by following links. llms.txt is the emerging convention for telling an assistant which pages actually matter.
  2. Mark the content with <main>
    The content-reachability check scores 16/100: with no <main> or <article> landmark, or with most of the page outside it, an assistant reads the navigation and the footer at the same cost as the text it came for.
  3. 2 crawlers are named and refused in robots.txt — a deliberate choice
    ClaudeBot, GPTBot are blocked by a rule that names them. Nothing to fix here: this page records what is true, not what should be. It is listed so the deliberate part of the block is not confused with the accidental part above.

Get told if this changes

One email only when a measured crawler flips on jku.at, served to refused or back. No schedule, no newsletter; double opt-in, one-click stop.

Method. 5 live HTTP requests (one per crawler, one as a browser) plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each, from a single vantage point. Blocking AI crawlers is a legitimate choice, not a failure: this page records what is true, not what should be. Domain comes from a shop-platform seed (Shopify/WooCommerce/Magento/BigCommerce/Shopline fingerprint or JSON-LD price), not the Tranco traffic ranking. One page per domain — the homepage — is audited.
