XML Sitemap Validator
A sitemap should be a clean discovery list of canonical URLs you want indexed. This validator reads normal XML, sitemap indexes, and gzip-compressed files while applying strict size and safety limits.

No signup. Be considerate when checking websites you do not own.
What this tool helps you see
- Parse sitemap indexes and URL sets
- Show duplicates, skipped values, and child sitemap results

How to use the result
- Enter the complete sitemap URL.
- Review parsing and child-sitemap messages.
- Remove redirects, errors, duplicates, and non-canonical URLs from the source file.
A checker can show evidence, but it cannot know your business intent. Confirm that every change still makes the page clearer and more useful for the person who searched.
Frequently asked questions
Does a sitemap guarantee indexing?
No. It helps discovery and communicates preferred URLs, but each page must still be useful, accessible, and eligible for indexing.
Should redirected URLs appear in a sitemap?
No. List the final canonical 200-status URL instead.
How should lastmod be used?
Update it only when the page changes meaningfully. Automatically publishing today’s date on unchanged pages makes the signal less useful.
