2 access agent(s) blocked: YouBot, Amazonbot — these keep your site out of AI answers.

修正 · WordPress: Use Yoast/Rank Math’s robots.txt editor (or a plugin) and ensure no Disallow for AI user-agents.

No HTTP Link: response headers. Emit canonical/alternate/describedby relations so HEAD-only or stream-rendering agents get them without parsing HTML.

修正: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.

Visible text is 2.9% of HTML weight (10426/354071 bytes). Low. Markup may be crowding out agent-usable text.

修正: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.

Browser pass unavailable; HTML looks like a JS-shell (e.g. #__next / #root). Likely JS-dependent.

修正 · WordPress: Most themes render server-side. Check that page builders (Elementor/Divi) aren’t deferring text to JavaScript, and disable JS lazy-loading for body copy.

<title> is 80 characters; keep it under 70 so it isn't truncated.

修正: Add a concise <title> tag. Agents often cite it verbatim.

1 recommended-field warning(s). First: Organization recommends "sameAs" (improves agent comprehension).

修正: Validate your JSON-LD with Google Rich Results test. Fix missing required properties.

This scan shows whether an agent can read the site. One free probe asks a real assistant a real buying question and records who it cited.

採点したのはトップページだけです。価格・ドキュメント・購入ページは別のページにあり、アシスタントが引用するのはまさにそれらのページです。ここで67/100ということは、最も磨いたページですらエージェントが見逃しているということ。Deep Scan（$29）はサイト全体を全31チェックで監査し、失敗したチェックとその具体的な修正を、可視性への影響が大きい順にまとめたPDFをメールで送ります。1回限り・数分で納品・サブスクリプションなし。
