Can AI assistants read impress.co.jp?

Measured on 2026-09-18 by asking the site 5 times — once as a browser, once as each of the 4 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 #6,563.

What to change, in order

  1. 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.
  2. Fix the plain structure: one <h1>, a title, a description, alt text
    The structure check scores 17/100. These are the cheapest signals on the page and the first ones an assistant uses to decide what the site is.

Method. 5 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 the Tranco research list. One page per domain — the homepage — is audited.
