Sitemap Validator

Validate XML sitemaps — checks urlset/sitemapindex root, loc entries, XML declaration, and URL count. Supports standard sitemap protocol formatting. Code never leaves your device — formatting and validation run locally in your browser.

How to Use the Sitemap Validator

1. Enter the sitemap URL or XML

A live /sitemap.xml address or pasted sitemap markup.

2. Read URL-level errors

Malformed loc entries, non-200 targets, and protocol violations listed per URL.

3. Resubmit to Search Console

Fix flagged URLs, then resubmit the sitemap so Google recrawls clean.
