- Paste your sitemap XML.
- Read the URL count and any issues.
- Fix the flagged problems.
FAQ
How do I validate an XML sitemap for free?
Paste it and this page detects whether it is a URL set or a sitemap index, counts the locations, and flags problems such as relative URLs or missing entries — on your device with no upload.
What problems does it catch?
Missing root elements, <loc> values that are not absolute http(s) URLs, entries with no location, and sitemaps over the 50,000-URL limit that should be split.
Is my sitemap uploaded anywhere?
No. Validation runs entirely in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.
Does it check that the URLs actually load?
No — it validates structure and URL format only. It does not fetch the URLs, which keeps it network-zero.
Limits
Checks structure and URL format; it does not verify each URL responds or crawl linked sitemaps.
