How to Use This Utility

  1. Paste raw XML sitemap content or load the pre-built sample template.
  2. Click Validate to parse root declarations (<urlset> or <sitemapindex>).
  3. Inspect detected URL counts, duplicate links, and lastmod ISO 8601 timestamp compliance.
  4. Resolve highlighted syntax or namespace errors before submitting to Google Search Console.

Methodology & Formula

A single XML sitemap file must not exceed 50,000 URLs or 50MB uncompressed size. Large sites must organize multiple sitemap files using a parent <sitemapindex> container.

Worked Example

Validates that every <loc> element contains a fully qualified HTTPS URL and that dates match the W3C datetime format (e.g. 2026-10-26T00:00:00Z).

Frequently Asked Questions

Do search engines pay attention to changefreq and priority tags in XML sitemaps?

Google search engineers have confirmed that Googlebot largely ignores changefreq and priority values, prioritizing the lastmod timestamp and actual content crawl history instead.

Why is lastmod considered the most critical sitemap tag?

Accurate lastmod timestamps inform Googlebot when content has actually been updated, preserving crawl budget by skipping unchanged pages.

Can I include non-canonical URLs in my sitemap?

No. XML sitemaps should exclusively contain 200 OK indexable canonical URLs. Redirects (301/302), broken links (404), and noindexed URLs should be purged.
