Can AI assistants read sae.edu?
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.
F43 / 100
1 of 6 crawlers can read this page.
More readable than 5% of the 47,315 sites measured so far.

| 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 |
| Meta-ExternalAgent (Meta AI) | 403 | challenged | allowed-by-star |
| Amazonbot (Alexa, Rufus) | 403 | challenged | allowed-by-star |
What to change, in order
- Let in the 5 crawlers your own robots.txt already allows+5 crawlersClaudeBot, GPTBot, PerplexityBot, Meta-ExternalAgent, 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. 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 1 to 6 of 6 crawlers.
- Put the text in the HTML, not only in JavaScriptThe HTML that arrives is nearly empty and the content is painted by JavaScript. None of these crawlers run it, so even the ones that are served read a blank page. Server-rendering or prerendering the main content is what changes their result.
- 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.
