Official statement

Changing URLs to force reindexing results in a complete loss of all historical information tied to the old URLs. Google no longer recognizes if there was a no-index tag, nor does it retain any data about those pages. This method is therefore risky and generally not recommended.

TL;DR

Altering a URL wipes out its associated SEO history. This is risky as it erases crucial information about your pages. Think carefully before proceeding.

❓ Frequently Asked Questions

Que se passe-t-il si je change une URL sans redirection ?
Google perd toute trace de l'historique de la page, affectant potentiellement votre classement.
Les redirections peuvent-elles conserver l'historique ?
Les redirections 301 aident à atténuer la perte, mais ne conservent pas toujours l'intégralité de l'historique SEO.
Une modification d'URL est-elle irréversible ?
Techniquement, non, vous pouvez revenir en arrière, mais la récupération complète des données est incertaine.
