Google recognizes lazy loading images using data-src, provided the final render displays the image element correctly. To ensure indexing, add structured image data or use an image sitemap.
❓ Frequently Asked Questions
Pourquoi utiliser data-src pour le lazy loading ?
Data-src réduit le chargement initial des pages en différant le rendu des images non visibles. Cela optimise la performance utilisateur.
Comment s'assurer que mes images sont bien indexées ?
Utilisez un sitemap d'images, des données structurées, et testez le rendu réel de vos pages pour garantir leur visibilité.
Les données structurées sont-elles obligatoires pour indexer des images en lazy loading ?
Non, mais elles facilitent grandement la compréhension par Google des éléments visuels de votre site.
