One address, not two (root → www)

Two addresses, one site. pangaea.id and www.pangaea.id look identical to you — but to Google they're two sites, and they split your SEO credit in half.

So we picked one. www.pangaea.id is canonical — it's what the sitemap, the hreflang tags and every canonical link point at — and the bare pangaea.id does a 301 ("moved permanently") to it. One Cloudflare Redirect Rule, and all the credit lands on a single URL (paths and query strings carried over intact).

The exact rule — and why a 301, not a temporary 302 — is in the companion walkthrough, Root → www: the 301 redirect →.
