SEO on-page
Liens cassés
Pourquoi c’est important
Links that lead to errors frustrate visitors, waste crawl activity and leak the value that links pass between pages.
Comment corriger
- Update or remove links that return 404 or 5xx errors.
- Add 301 redirects for pages that moved.
- Re-check links regularly, especially after deleting pages.
