What Is the Sitemap Validator?

Sitemap Validator fetches and parses any XML sitemap, validates its format, reports the number of URLs, detects errors, and distinguishes between standard sitemaps and sitemap index files. Essential for SEO audits.

Key Features

XML Parsing: Validates that the sitemap is well-formed XML.
URL Counting: Reports total URLs in the sitemap.
Index Detection: Identifies sitemap index files vs standard sitemaps.
Error Reporting: Flags missing <loc> elements, malformed URLs, and parse failures.

📋 When to Use

Use to verify sitemaps after site migrations, check that all important pages are listed, debug Google Search Console sitemap errors, and ensure sitemap index files are correctly structured.

⚙️ How It Works

The tool fetches the sitemap URL via the ToolStand proxy, parses it with the browser's DOMParser, and inspects the XML structure. It reports root element type (urlset or sitemapindex), counts entries, and lists any errors found.

How to Use the Sitemap Validator

Enter the sitemap URL (e.g. https://yoursite.com/sitemap.xml).
Click Validate to fetch and parse.
Review the summary with URL count and sitemap type.
Check the URL list and any reported errors.
