Validate XML sitemaps, robots.txt directives, and indexing rules in one click.

Paste a sitemap to validate it — parsing happens entirely in your browser.

What "valid" actually means

A valid XML sitemap is one that Google can parse without errors. That means a correct root element (urlset for URL sitemaps or sitemapindex for index files), a proper namespace, no syntax errors, and URLs that are absolute (not relative). The 50,000-URL and 50 MB limits are hard limits — exceed them and Google silently drops the file.

Common sitemap mistakes

  1. Relative URLs (/about instead of https://…/about).
  2. Including 404s or redirected URLs.
  3. Mixing https and http in one sitemap.
  4. Stale or future lastmod dates that don't match the page content.
  5. Forgetting to reference the sitemap in robots.txt.

How the robots.txt tester decides

Enter any bot (name or full UA string) and any path and the tester replicates Google's interpretation: the groups whose token matches your bot — exactly, or as the longest case-insensitive prefix — win (falling back to *), their rules are merged, and thelongest matching path pattern decides the outcome — with Allow winning ties. Patterns support * wildcards and the $ end anchor. An emptyDisallow: means "allow everything", which is not the same asDisallow: /.
