Can AI assistants read doug.mobi?

Measured on 2026-09-20 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.

What each crawler got back

What to change, in order

1. Let in the 1 crawler your own robots.txt already allows+1 crawler
   Bytespider 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 6 to 7 of 8 crawlers.
2. Declare the facts in JSON-LD
   There 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.
3. Publish llms.txt
   llms.txt is 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.
4. Mark the content with <main>
   The content-reachability check scores 30/100: with no <main> or <article> landmark, or with most of the page outside it, an assistant reads the navigation and the footer at the same cost as the text it came for.
5. 1 crawler is named and refused in robots.txt — a deliberate choice
   GPTBot 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.
