    WWW vs non-WWW

    www and non-www are different hosts. Pick a preferred host, use permanent redirects, and keep canonicals/sitemaps consistent.

    Definition

    `www.example.com` and `example.com` are different hosts. If both serve the same content, you’ll create duplication and split signals. Choose one preferred host and consolidate with permanent redirects and canonicals.

    Why it matters

    • Avoid splitting authority across two hosts
    • Reduce duplicate content and indexing confusion
    • Keep sitemaps, canonicals, and hreflang consistent

    How to implement

    • Choose a preferred host (www or non-www)
    • 301/308 redirect the other host to the preferred one
    • Use the preferred host in canonicals, sitemaps, and internal links
