About this tool
A sitemap validator helps identify malformed XML and practical content problems before a sitemap is submitted to search engines. This tool recognizes URL sitemaps and sitemap indexes, checks location values and highlights duplicate or excessive entries.
Common use cases
- ✓ Validate a generated sitemap before deployment.
- ✓ Inspect a sitemap returned by a CMS or framework.
- ✓ Find duplicate or malformed location entries.
- ✓ Review whether a file is a URL sitemap or sitemap index.
How to use it
- Paste the complete sitemap XML.
- Review the detected document type and URL count.
- Resolve any XML or URL errors.
- Submit the corrected sitemap through your search engine console.
Important interpretation notes
- • A valid sitemap does not guarantee crawling or indexing.
- • List canonical, indexable production URLs rather than redirect or parameter duplicates.
- • This validator does not fetch linked child sitemaps from a sitemap index.

Frequently asked questions
What sitemap formats are supported?
The validator checks standard URL sitemaps with a urlset root and sitemap indexes with a sitemapindex root.
Does this tool submit my sitemap to Google?
No. It validates pasted XML locally and does not submit or fetch anything.
How many URLs can one sitemap contain?
A standard sitemap file should contain no more than 50,000 URL locations and be no larger than 50 MB uncompressed.
Are duplicate URLs invalid?
Duplicates are reported as a warning because they waste sitemap space and can make maintenance harder.
Does valid XML guarantee indexing?
No. A valid sitemap helps discovery but does not guarantee that search engines will crawl or index every URL.
Should sitemap URLs use HTTPS?
Use the canonical protocol and hostname that you want search engines to index, usually HTTPS for a secure production site.
