Can AI assistants read opendatacommons.org?

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.

What each crawler got back

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

1. 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.
2. Publish sitemap.xml and llms.txt
   sitemap.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.
3. Fix the plain structure: one <h1>, a title, a description, alt text
   The structure check scores 58/100. These are the cheapest signals on the page and the first ones an assistant uses to decide what the site is.
