Free XML Sitemap Validator — Test, Check & Fix Your Sitemap
Check your XML sitemap for errors, test against schema, and find noindex URLs to ensure perfect Google indexing
Validate Your XML Sitemap
Note: This tool validates your sitemap against the official sitemap protocol and checks for common issues that might prevent search engines from properly indexing your content.
How to Validate Your Sitemap in 3 Steps
Enter your Sitemap URL
Paste the complete URL of your sitemap (e.g., example.com/sitemap.xml) into the validator tool. You can also upload an XML file or paste the code directly.
Run the Validation Check
Click "Validate Sitemap". The tool will process your sitemap against schema standards, check for 404 links, identify noindex tags, and verify limits.
Fix Errors and Submit
Review the detailed report. Once all errors are resolved and your sitemap is clean, submit it directly to Google Search Console to boost indexing.
What Does a Valid XML Sitemap Look Like?
A valid XML sitemap must follow the strict http://www.sitemaps.org/schemas/sitemap/0.9 protocol. Search engines like Google are very strict about this formatting. A single typo or invalid tag can cause the entire sitemap to be rejected.

Common Sitemap Errors and How to Fix Them
Our sitemap checker identifies critical issues that prevent Google from crawling and indexing your pages. Here are the most common errors and their solutions:
Error: Sitemap URL Not Accessible to Crawlers
If Googlebot cannot access an individual URL inside your sitemap (e.g., it returns a 404 Not Found, 403 Forbidden, or 500 Server Error), it wastes crawl budget.
How to fix: Use our tester tool to identify broken URLs. Remove any URL from your sitemap that does not return a 200 OK status code. If a page was moved, implement a 301 redirect and update the sitemap with the new final destination URL.
Error: noindex URLs Found in Sitemap
Your sitemap is a list of pages you want Google to index. If you include a URL in your sitemap that contains a <meta name="robots" content="noindex"> tag or an X-Robots-Tag HTTP header, you are sending conflicting signals to search engines. Google considers this a critical error.
How to fix: Our sitemap checker flags conflicting URLs. You must either remove the noindex tag from the page (if you want it indexed) or remove the URL entirely from your sitemap (if you want it kept hidden).
Error: Sitemap Exceeds 50,000 URL Limit
Google enforces strict size limits on XML sitemaps: a single file can contain a absolute maximum of 50,000 URLs and must be under 50MB (uncompressed). If you exceed this, Google will halt processing the file.
How to fix: Automatically compress your sitemap formats using gzip (.xml.gz). If you still exceed 50,000 URLs (or 50MB), you must break your sitemap into multiple smaller files (e.g., sitemap1.xml, sitemap2.xml) and tie them together using a Sitemap Index file. Our validator supports checking sitemap index files.
Sitemap Validation vs Google Search Console Submission
Many webmasters confuse validating a sitemap with submitting one. Both are required for optimal technical SEO, but they serve different purposes.
1. Validation (Testing)
Testing your sitemap ensures the code is structurally sound, limits aren't exceeded, and no "junk" URLs (like 404s or noindex pages) are included. This is done before Google even sees it using a tool like our free validator.
2. Submission (GSC)
Once tested and verified, you submit the sitemap URL directly to your Google Search Console account. This actively requests Googlebot to crawl the verified URLs and report back on their indexing status.
