要改善

これは(ブラウザではなく)AIエージェントから見たdev.toの姿です。スコアは機械可読性の5カテゴリを重み付けし、弧の目盛りはその背後にある31件の個別チェックです。

✉ このレポートをメールで受け取り、変化を通知 ↓

チェックの技術的な詳細は英語で表示されます — スキャナーの出力をそのまま示しているためです。

優先すべき修正

「emerging」タグの付いたチェックは、まだウェブの大半が採用していない2026年のエージェントプロトコル標準です — 早期採用は欠点ではなく強みです。

failSitemap present発見可能性

No reachable sitemap.xml. Publish one and reference it in robots.txt.

修正 · Webflow: Publish /sitemap.xml and reference it from robots.txt with a Sitemap: line.

failJSON-LD present構造化データ

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

修正 · Webflow: Add JSON-LD in Page Settings → Custom Code (inside <head>) for the page’s type.

failText-to-markup ratio可読性

Visible text is 3.3% of HTML weight (8600/260416 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%.

warnLink response headers発見可能性

A Link: header is present but carries none of canonical/alternate/describedby — the relations agents consume.

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

warnHeading hierarchy可読性

Heading issues: 1 skipped level(s).

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

failContent-Signal directivesemerging発見可能性

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.

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。

このスコアを追跡

このレポートをメールで受け取り、dev.toの対応状況が実際に変化したとき — チェックの悪化や総合スコアの低下 — に通知を受け取れます。

メールが送られないケースが2つあります: 当社が新しいルーブリックを公開したことによるスコア変化(測定器が変わっただけで、サイトの変化ではありません)と、実行のたびに揺れる時間依存チェックだけで説明できる変動です。

自分のスケジュールで、メールの代わりにSlackやWebhookで受け取りたい場合は スコアドリフト監視 をどうぞ — すべての有料プランに含まれています。

このスコアはAIエージェントがdev.toを読み取れるを示します。 AIトラフィック分析 は、実際に来たかどうか — そしてどのページが追い返したか — を示します。
