Can AI assistants read enhance.co.jp?
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 to change, in order
- Publish llms.txtllms.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.
- Mark the content with <main>The content-reachability check scores 3/100: 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.
- Fix the plain structure: one <h1>, a title, a description, alt textThe structure check scores 57/100. These are the cheapest signals on the page and the first ones an assistant uses to decide what the site is.

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.
