SEO technique
www / sans www
Pourquoi c’est important
If both www and non-www versions load, search engines see duplicate sites and links are split between them.
Comment corriger
- Choose one version (with or without www).
- 301-redirect the other version to it and use the chosen one in canonical tags and sitemaps.
Vérifier avec
- Redirect Generator (.htaccess & Nginx) – Create 301 redirect rules for Apache .htaccess and Nginx, including HTTPS and www.
- Redirect Checker – Trace every hop of a redirect chain with status codes and timings.
