Can AI assistants read oma.be?
Measured on 2026-09-19 by asking the site 7 times — once as a browser, once as each of the 6 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.

| 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 | no-rule |
| Meta-ExternalAgent (Meta AI) | 403 | challenged | no-rule |
| Amazonbot (Alexa, Rufus) | 200 | can read it | no-rule |
What to change, in order
- Let in the 1 crawler your own robots.txt already allows+1 crawlerMeta-ExternalAgent is turned away before reading the page (served a bot challenge instead of the page), while robots.txt permits it — so this block is not written in your site. No CDN signature was found in the response headers, so the refusal comes from the origin server itself or from a WAF this index does not recognise. Fixing it takes this domain from 5 to 6 of 6 crawlers.
- 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.

Method. 7 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.
