Sitemap Validator
Paste XML sitemap content to validate structure and check for common issues.
- Check URL sitemap and sitemap index files
- Find missing or malformed URLs
- Identify duplicate entries
- Local processing only
This validation runs locally in your browser. Your sitemap content is never sent to any server.
What is an XML sitemap?
An XML sitemap is a file that lists the important URLs for a website, helping search engines discover and crawl content more efficiently. There are two main types of sitemaps:
URL Sitemaps vs Sitemap Indexes
URL Sitemaps use the <urlset> root element and list individual page URLs.
Each URL entry should contain at least a <loc> element with the URL location.
Sitemap Indexes use the <sitemapindex> root element and list other sitemap files.
They are used when you have more than 50,000 URLs or want to organize sitemaps by content type.
Required and optional elements
Every entry in a sitemap requires a <loc> element with a valid absolute URL.
Additional optional elements include <lastmod> (last modification date),
<changefreq> (change frequency), and <priority> (relative priority).
How the validator helps
The Sitemap Validator checks your XML content for structural validity and common issues. It identifies missing locations, duplicate entries, malformed URLs, and other common sitemap problems. This helps ensure search engines can properly parse and use your sitemap.
Limitations
This validator checks the XML structure and common issues locally in your browser. It does not fetch URLs to verify they return 200 status codes or check whether pages are properly indexable. Protocol validation and actual search engine indexing are separate concerns.
FAQ
Does this tool upload my sitemap content?
No. All processing happens in your browser. Your content remains private and secure.
What sitemap formats are supported?
The validator supports standard URL sitemaps (<urlset>) and sitemap indexes (<sitemapindex>).
It handles the standard sitemap namespace: xmlns="http://www.sitemaps.org/schemas/sitemap/0.9".
Can the validator check if URLs are accessible?
No, the validator only checks the XML structure and common issues. It does not fetch or verify the accessibility of listed URLs. For URL status checking, you would need a separate crawling tool.
