TL;DR

Google transfers signals via a 301 redirect, but the *relevance* of the new URL remains crucial. Don't settle for just a redirect; optimize the content too.

❓ Frequently Asked Questions

Qu'est-ce qu'une redirection 301 ?
Une redirection 301 est un code HTTP indiquant un déplacement permanent d'une URL vers une nouvelle adresse.
Transfère-t-elle tous les signaux SEO ?
Non, elle transfère une grande partie des signaux, mais pas l'intégralité. La qualité on-page influence aussi la performance.

Google ne précise pas le pourcentage exact, mais une légère dilution du PageRank est possible.
