Free XML sitemap validator

It lists the pages you want search engines to index, so they can find them even when internal links are weak. It doesn’t force indexing — but a clean sitemap of real, indexable pages helps Google crawl the right things.

Only canonical, indexable pages that return 200 — the URLs you want in Google. Leave out redirects, 404s, noindex pages, pages blocked by robots.txt and duplicates whose canonical points elsewhere. Those are exactly what this tool flags.

Your sitemap lists URLs that tell Google not to index them, or that no longer exist. Remove them from the sitemap (usually a CMS or plugin setting) or fix the pages, then resubmit.

50,000 URLs and 50 MB uncompressed per file. Bigger sites split into several sitemaps listed in a sitemap index. An index can’t list other indexes.

Google uses lastmod when it’s consistently accurate — so it should be the real date the content changed, not the build time. It ignores changefreq and priority entirely.

Fetching every page of a large site takes a long time, so we test a sample of up to 500 spread evenly across all your sitemaps — enough to reveal systematic problems. Every URL is still checked for format, host and robots.txt rules.
