Impact sur la performance

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).

Recommandations

Problèmes signalés par Lighthouse sur les 122 page(s) échantillonnée(s), au-delà des scores principaux — regroupés par catégorie et classés selon le nombre de pages concernées.

Ce que signifie le score Agentique

Le score Agentique (prêt pour l'IA) est nouveau dans Google Lighthouse (13.4+). Il mesure dans quelle mesure une page fonctionne pour les agents et assistants IA — les outils qui interviennent de plus en plus dans la façon dont les gens trouvent et utilisent les services publics. Il vérifie des éléments comme un fichier llms.txt (un guide lisible par machine pour les modèles de langage), des données structurées valides, un arbre d'accessibilité bien formé que les agents peuvent analyser, et des descriptions d'outils/formulaires WebMCP. Un score plus élevé signifie qu'un assistant IA a plus de chances de comprendre la page et d'accomplir correctement des tâches au nom d'un citoyen.

C'est expérimental et en évolution ; considérez-le comme un signal prospectif, pas comme une exigence de conformité. Médiane sur les pages échantillonnées : 67/100.

Lacunes trouvées sur les pages échantillonnées : 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).
