How to Use Sitemap Validator — XML Sitemap Checker
How to Use Sitemap Validator
Step 1: Paste Your Sitemap XML
Copy the contents of your sitemap.xml file and paste it into the input field. You can also use one of the built-in examples to explore the tool.
Step 2: Click Validate Sitemap
Press the Validate Sitemap button to run validation. The tool checks:
- XML well-formedness
- Root element (
<urlset>or<sitemapindex>) - Namespace declaration (xmlns)
- Required fields per entry (
<loc>for each<url>or<sitemap>) <changefreq>values against the allowed set<priority>values in the 0.0–1.0 range- URL count against the 50,000-per-file spec limit
Step 3: Review Results
Field Checks — confirms which fields are present or missing.
Errors — issues that make the sitemap invalid (missing <loc>, invalid priority, etc.).
Warnings — non-blocking recommendations (missing <lastmod>, etc.).
URL / Sitemap Entries Preview — shows the first 10 entries with their field values and any per-entry issues.
Sitemap Types
- URL Sitemap —
<urlset>root; lists individual page URLs - Sitemap Index —
<sitemapindex>root; lists child sitemap files
Tips
- Always include
<lastmod>— it helps search engines prioritise crawling - Keep individual sitemaps under 50,000 URLs and under 50 MB uncompressed
- Use a sitemap index to split large sites across multiple files
- Submit your sitemap URL to Google Search Console and Bing Webmaster Tools
