Si le chargement de votre contenu principal dépend à 100 % de JS, l'indexation par Google peut prendre des semaines, ou tout simplement l'abandonner si le temps de rendu est excessif. C’est pourquoi le HTML statique (SSR/SSG) est crucial.</p> </article><article class="rounded-2xl border border-gray-200 p-5"> <h3 class="text-lg font-bold text-black"> Quand dois-je utiliser les balises « canoniques » par rapport aux redirections 301 ? </h3> <p class="mt-2 text-gray-700 leading-relaxed">Le système `canonical` est utilisé lorsque les deux pages doivent exister fonctionnellement pour l'utilisateur (ex. un ecommerce qui permet de trier par prix, ce processus génère une URL paramètre `?sort=price`). L'URL avec le paramètre inclut une balise canonical pointant vers la principale. Une redirection 301 est utilisée lorsque les anciennes pages meurent de manière permanente et que leur trafic doit être redirigé.</p> </article><article class="rounded-2xl border border-gray-200 p-5"> <h3 class="text-lg font-bold text-black"> Les balises 'hreflang' sont-elles vraiment importantes sur les sites multilingues ? </h3> <p class="mt-2 text-gray-700 leading-relaxed">Absolument critique, sinon vous encourrez des pénalités massives pour le contenu en double. Si vous avez /es/ and /en/, le `hreflang` connecte les deux entités, en disant à Google : « il s'agit de la version espagnole pour les utilisateurs en Espagne, et il s'agit de la version anglaise ». Ils doivent se faire référence mutuellement en utilisant des URL absolues.</p> </article><article class="rounded-2xl border border-gray-200 p-5"> <h3 class="text-lg font-bold text-black"> Un mauvais Core Web Vital peut-il faire couler mon classement ? </h3> <p class="mt-2 text-gray-700 leading-relaxed">L'algorithme de Google inclut explicitement les statistiques relatives à l'expérience sur la page (LCP, INP, CLS) en tant que facteur de classement. Dans une niche compétitive où le contenu est de la même qualité, le site Web qui se charge le plus rapidement et bloque le fil principal le moins atteindra systématiquement les positions phares.</p> </article> </div> </section> <section class="mt-12 w-full max-w-4xl mx-auto"> <h2 class="text-3xl md:text-4xl font-bold tracking-tight text-black mb-6 text-center">
