www / non-www

Why it matters

If both www and non-www versions load, search engines see duplicate sites and links are split between them.

How to fix it

1. Choose one version (with or without www).
2. 301-redirect the other version to it and use the chosen one in canonical tags and sitemaps.

Check it with

• 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.

Scoring: a passed check earns its full weight, a warning half and an error none. How the SEO score works
