# Keep sitemap URLs on the correct domain

Google ignores sitemap entries from domains it cannot verify as yours — cross-domain URLs are simply skipped, meaning those pages lose the crawl-discovery benefit of the sitemap.

## Quick Reference

- Every `<loc>` URL must use the same domain and protocol (`https://www.example.com`) as the sitemap file itself
- Cross-domain URLs in a sitemap are ignored by Google
- Mixing `http://` and `https://` URLs in one sitemap creates conflicting signals
- Mixing `www` and non-`www` variants indicates a canonicalization issue to fix first

## Check

Parse all `<loc>` values in the sitemap and extract the protocol and hostname. Flag any URL whose protocol or hostname differs from the sitemap's own URL. Common mismatches: http vs https, www vs non-www, old domain vs new domain.
