No JSON-LD blocks found. Add a <script type="application/ld+json"> with a schema.org type for this page.

修正 · Next.js: Emit JSON-LD from a Server Component or the Metadata API: a <script type="application/ld+json"> with Organization / Article / Product for the page.

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 1.6% of HTML weight (8168/505215 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 · Next.js: Render primary content on the server: use Server Components (App Router) or getServerSideProps/SSG (Pages Router). Avoid fetching above-the-fold content in a client useEffect, since agents don’t run it.

Heading issues: 1 skipped level(s).

修正: Use a single H1 and avoid skipping heading levels (H1 → H3).

No Content-Signal directives. Add e.g. `Content-Signal: ai-train=no, ai-summarize=yes` to declare granular AI usage policy beyond binary allow/disallow.

修正: Add `Content-Signal:` directives to your robots.txt. This is the emerging standard (Cloudflare-driven) for declaring fine-grained AI usage policy beyond a binary allow/disallow.

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68/100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。
