How to use the Sitemap Validator?

A broken sitemap can prevent search engines from discovering your content. Use this tool to ensure your XML file is error-free before uploading it to your server.

Get Source: Open your sitemap.xml file in a text editor or browser and copy the entire code.
Paste: Paste the code into the input field above.
Validate: Click "Validate Sitemap". Our tool checks the XML tags, the required schema namespace, and the URL structure.
Fix: If errors are found (e.g., mismatched tags or missing locators), fix them in your sitemap generator and re-test.

Key Features

Syntax Auditing

Detects unclosed tags, illegal characters, and formatting errors that crash search engine crawlers.

URL Extraction

Automatically parses and lists every URL contained in the sitemap for easy manual review.

Privacy Secure

Your sitemap data is analyzed locally. We never store your website's URL architecture on our database.

Frequently Asked Questions

What is a sitemap namespace?

A namespace (usually xmlns="http://www.sitemaps.org/schemas/sitemap/0.9") is a standard attribute that tells search engines exactly which version of the sitemap protocol you are using. Without it, the sitemap may be ignored.

Why does Google say my sitemap is invalid?

Common reasons include: encoding issues (not UTF-8), URLs that include special characters not escaped (like & instead of &), or the file size exceeding 50MB.

How many URLs can a sitemap have?

A single sitemap file can contain a maximum of 50,000 URLs. If you have more, you should use a "Sitemap Index" file to group multiple sitemaps together.
