Can AI assistants read computerbild.de?
Measured on 2026-09-13 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. Tranco rank #15,896.

| Crawler | HTTP | Result | robots.txt |
|---|---|---|---|
| ClaudeBot (Claude) | 200 | can read it | allowed-by-star |
| GPTBot (ChatGPT) | 200 | can read it | allowed-by-star |
| OAI-SearchBot (ChatGPT Search) | 200 | can read it | allowed-by-star |
| PerplexityBot (Perplexity) | 200 | allowed by the server, blocked in robots.txt | blocked |
| Google-Extended (Gemini, AI Overviews) a robots.txt token, not a crawler: it controls how already-crawled pages may be used, and never makes a request of its own | — | not opted out | allowed-by-star |
What to change, in order
- Publish sitemap.xml and llms.txtsitemap.xml and llms.txt are 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.
- Mark the content with <main>The content-reachability check scores 1/100: 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.
- 1 crawler is named and refused in robots.txt — a deliberate choicePerplexityBot is blocked by a rule that names it. 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.

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.
