Can AI assistants read cmd.su?
Measured on 2026-09-19 by asking the site 9 times — once as a browser, once as each of the 8 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 #6,265.

What to change, in order
- Declare the facts in JSON-LDThere is no JSON-LD on the page, so every fact — who you are, what you sell, the price — has to be guessed out of the prose and the layout. A schema.org block is the difference between being quoted correctly and being paraphrased.
- 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. 9 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.
