Validate XML sitemaps with sitemap index support. Check for errors, detect duplicates, verify Google compliance, and export results as CSV.
An XML sitemap is a file that lists all the important URLs on your website, helping search engines discover, crawl, and index your pages efficiently. Think of it as a roadmap for Google, Bing, and other crawlers.
Helps search engines find pages that might not be discovered through internal linking alone.
The lastmod date tells crawlers when content was last updated, prioritizing fresh content.
Large sites use sitemap indexes to organize URLs into logical groups (blog, products, pages).
Use this validator to check items 2-6 automatically. For items 7-8, check your robots.txt and monitor Google Search Console.
XML sitemaps help search engines discover and crawl your pages efficiently. A valid sitemap follows specific rules:
Invalid XMLMissing closing tags, incorrect nesting, or unescaped characters (&, <, >).
Wrong dateUsing formats like "01/15/2024" instead of "2024-01-15".
Relative URLsUsing "/page" instead of "https://example.com/page".
Too largeOver 50,000 URLs or 50MB file size. Use sitemap index for large sites.
Stop maintaining sitemaps manually. Use a module to generate them automatically from your routes.
A sitemap validator is a tool that checks your XML sitemap for errors, validates URL format, and ensures compliance with the sitemaps.org protocol. It helps ensure search engines can properly crawl and index your website.
Enter your sitemap URL (e.g., example.com/sitemap.xml) above and click Validate. This sitemap checker will fetch your sitemap, parse all URLs, and validate against Google's sitemap requirements including lastmod dates, changefreq, and priority values.
Changefreq (change frequency) is an optional XML sitemap tag that tells search engines how often a page is likely to change. Values include always, hourly, daily, weekly, monthly, yearly, and never. Note: Google largely ignores this tag and relies on actual crawl data instead.
A sitemap index is a file that references multiple sitemaps. It's used when your site has more than 50,000 URLs or your sitemap exceeds 50MB. Each sitemap in the index can contain up to 50,000 URLs.
Use this sitemap tester to validate your sitemap structure, then submit it to Google Search Console. Google will show any crawl errors. Ensure your sitemap uses absolute URLs, valid lastmod dates (YYYY-MM-DD), and doesn't exceed size limits.
