Sitemap input is processed locally in your browser and not uploaded.

  • This tool validates structure only and does not fetch sitemap URLs for availability checks.
  • Wrong date formats or inaccessible sitemap files still fail in crawler processing.
  • A valid sitemap index does not guarantee full indexing without crawlable pages and quality signals.

FAQ

When do I need a sitemap index?

Use it when your site has multiple sitemap files by section, language, or content type.

Is lastmod required?

No, but it can help search engines understand update recency when values are accurate.

Can I include non-HTTPS sitemap URLs?

HTTPS is strongly recommended for crawler trust and consistency.

Does this check if sitemap URLs return 200?

No. It generates XML only; availability should be tested separately.

Should sitemap URLs be absolute?

Yes. Absolute canonical sitemap URLs are expected in sitemap index files.
