Can AI assistants read most-famous-paintings.com?
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.

Cloudflare answers for this domain. Where a crawler above is refused while robots.txt allows it, the rule is applied by that edge, not written by the site — see how often each edge does this.
What to change, in order
- Let in the 5 crawlers your own robots.txt already allows+5 crawlersClaudeBot, GPTBot, OAI-SearchBot, PerplexityBot, Meta-ExternalAgent are turned away before reading the page (served a bot challenge instead of the page), while robots.txt permits them — so this block is not written in your site. Cloudflare answers for this domain. Cloudflare applies AI-crawler blocking at the edge, independently of robots.txt (Security → Bots, plus the managed robots.txt feature). https://developers.cloudflare.com/bots/concepts/bot/ Fixing it takes this domain from 0 to 5 of 6 crawlers.
- 1 crawler is named and refused in robots.txt — a deliberate choiceAmazonbot 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. 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.
