Sitemap Validator

What is an XML Sitemap?

An XML sitemap is essentially a roadmap of your website that leads search engines to all your important pages. It tells crawlers where to find content, how often it's updated, and which pages are priorities. Without a correctly formatted sitemap, search engines might miss deep-linked pages or fail to recognize fresh updates, directly impacting your site's SEO performance.

Why use a Validator?

Even a small syntax error—like a missing closing tag or an ampersand that hasn't been escaped—can cause a search engine to reject your entire sitemap. Our validator checks for these common pitfalls, ensuring your file adheres to the official sitemaps.org protocol. It goes beyond simple syntax, looking for issues like invalid date formats in the <lastmod> tag and missing required <loc> fields.

How to Use This Tool

• From URL: Simply enter the full URL of your remote sitemap (e.g., https://example.com/sitemap.xml). Our server will safely fetch it to bypass CORS restrictions.
• Paste XML: If you are building a sitemap locally, just copy and paste the raw XML code directly into the validator.
• Upload: Have a file on your machine? Drag and drop your .xml file for an instant audit.

Visualization & Editing

Once parsed, you can switch to the Tree View to see your URLs in a clean, searchable list showing priority levels and change frequencies. Use the Code View to inspect the actual XML structure. If your code is messy or minified, use our built-in formatter to add proper indentation, making it easier to read and debug.
