SERPInsight

Sitemap Validator

Enter your Sitemap URL to validate XML syntax, file size, and standard compliance.

Supports standard XML sitemaps and Sitemap Indices.

What does this tool do?

The SERPInsight Sitemap Validator analyzes your XML sitemap to ensure it is compliant with search engine standards (Sitemaps Protocol). It checks for syntax errors, incorrect tags, and file limitations.

A valid sitemap is crucial because it acts as a roadmap for Googlebot. If your sitemap contains errors, search engines may stop processing it, resulting in your newest pages not being indexed.

Critical issues (like broken XML or 404s) that stop the file from working.

Frequently Asked Questions

What is the maximum limit for a sitemap?
A single sitemap file cannot exceed 50MB (uncompressed) or contain more than 50,000 URLs. If you exceed this, you must split your list into multiple sitemaps and use a Sitemap Index file.
Does this tool check if my pages are indexed?
No. This tool validates the syntax and structure of the file itself. To check if Google has actually indexed the pages listed inside, you should use Google Search Console.
What are "Sitemap Index" files?
A Sitemap Index is a "parent" XML file that links to other sitemaps. This tool supports validating Sitemap Index files as well—it will check the structure of the index itself.
