パフォーマンスへの影響

How far pages fall short of Google's "good" benchmarks: Largest Contentful Paint ≤ 2.5s and page weight ≤ 1.6 MB. Lower is better.

Avg extra LCP over 2.5s: 12.4s 122/122 pages over
Avg extra weight over 1.6 MB: 2.13 MB 110/111 pages over

Set page_loads_per_week for this target to also estimate total wasted time and data (the way daily-dap uses traffic counts).

推奨事項

見出しスコアを超えて、Lighthouse が 122 件のサンプルページで指摘した問題。カテゴリ別にグループ化され、影響するページ数で順位付けされています。推定削減量(転送バイト数または読み込み時間)は、利用可能な場合は Lighthouse 自身の推定です。アクセシビリティ監査は意図的に省略されています。アクセシビリティページの axe-core の検出と重複するためです。

エージェント対応スコアの意味

エージェント対応(AI 対応度)スコアは Google Lighthouse(13.4 以降)の新機能です。これは、人々が行政サービスを見つけて利用する方法をますます仲介するツールである AI エージェントとアシスタントにとって、ページがどれだけ機能するかを測定します。llms.txt ファイル(言語モデル向けの機械可読ガイド)、有効な構造化データ、エージェントが解析できる適切に構成されたアクセシビリティツリー、WebMCP のツール/フォームの記述などをチェックします。スコアが高いほど、AI アシスタントがそのページを理解し、市民に代わってタスクを正しく完了できる可能性が高まります。

これは実験的で進化中です。コンプライアンス要件ではなく、将来を見据えたシグナルとして扱ってください。サンプルページの中央値: 67/100.

サンプルページで見つかった不足: WebMCP tools registered (122), WebMCP form coverage (122), WebMCP schemas are valid (122), llms.txt follows recommendations (122), Cumulative Layout Shift (36), Accessibility tree is not well-formed (1).
