Sitemap Validator
A sitemap with broken URLs, duplicates or malformed dates wastes crawl budget and can leave pages unindexed. Paste your sitemap XML and this validator checks every entry — URL validity, duplicates, lastmod dates, priority range and changefreq values — and lists exactly what needs fixing.
Use the tool
How to use the Sitemap Validator

Frequently asked questions
Does this fetch my live sitemap URL?
No — it validates the XML you paste here, entirely in your browser. To check a live sitemap, download it (or view source on its URL) and paste the contents above.
What counts as an error?
Invalid or missing URLs, duplicate URLs, lastmod dates not in YYYY-MM-DD form, priorities outside 0.0–1.0, unknown changefreq values, and sitemaps over the 50,000-URL limit.
Does a valid sitemap guarantee indexing?
No. It helps Google discover pages, but indexing still depends on content quality, internal links and crawl budget — use this alongside the other audit tools on this site.
