FAQ
Does this sitemap checker fetch my sitemap URL?
No. It validates only the XML you paste into the input (no network requests).
What sitemap types are supported?
It supports <urlset> sitemaps and <sitemapindex> indexes.
What does it validate in each entry?
It checks XML parsing, required <loc>, URL format, duplicates, and common fields like <lastmod>, <changefreq>, and <priority>.
How do I handle relative URLs in <loc>?
Enter a Base URL (e.g., https://example.com/) and the tool will resolve relative <loc> values.
Is an invalid <lastmod> a hard error?
It’s flagged because search engines expect ISO 8601 formatting; fix it to avoid ambiguity.
Will it verify that URLs return 200 status codes?
No. That requires fetching URLs; this tool focuses on offline XML and field validation.
Why might Google still reject a sitemap that looks valid here?
Google can reject sitemaps for fetch/access issues, blocked URLs, unsupported content types, or server errors—use a Google-focused validator and Search Console logs.
