Sitemap URL Checker Guide

Reference for reviewing sitemap URL lists before submission, including canonical hosts, redirects, duplicates, noindex pages, and stale routes.

Quick answer

Use the Sitemap URL Checker to review a pasted URL list or sitemap-derived URL set before submitting it to search tools. Look for duplicate URLs, old redirect paths, staging hosts, internal routes, and pages that should not be indexed.

What to check

  • Canonical production host
  • No duplicated URLs
  • No old redirect slugs
  • No dashboard, admin, checkout, or draft routes
  • No obvious noindex pages
  • Important new pages are present

Data handling and processing behavior

Processing is handled in the browser for this tool based on the current public implementation. Avoid entering private sitemap URLs unless you have reviewed the implementation and your own data handling requirements.

Step-by-step use

  1. Paste the sitemap URL list or exported URLs
  2. Review duplicate and malformed entries
  3. Check that all URLs use the canonical host
  4. Remove redirect sources and private routes
  5. Recheck after deployment before submitting

Common errors

Old slugs remain listed. Redirects are useful for users, but canonical sitemap entries should use final URLs.

Mixed hostnames. Do not mix www and non-www unless that is intentional and canonicalized correctly.

Private pages appear. Admin, dashboard, checkout, and auth pages should not be in the public sitemap.

Limits

This tool helps inspect URL hygiene. It does not replace a full crawler, Search Console coverage data, server logs, or live HTTP status checks.
