Agent Web Index › brt.it
Can AI assistants read brt.it?
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.
C72 / 100
3 of 6 crawlers can read this page.
More readable than 45% of the 47,934 sites measured so far.

What each crawler got back
| Crawler | HTTP | Result | robots.txt |
|---|---|---|---|
| ClaudeBot (Claude) | 403 | challenged | no-rule |
| GPTBot (ChatGPT) | 403 | challenged | no-rule |
| OAI-SearchBot (ChatGPT Search) | 200 | can read it | no-rule |
| PerplexityBot (Perplexity) | 200 | can read it | no-rule |
| 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) | 200 | can read it | no-rule |
| Amazonbot (Alexa, Rufus) | 403 | challenged | no-rule |
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 3 crawlers your own robots.txt already allows+3 crawlersClaudeBot, GPTBot, Amazonbot 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 3 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.
