Get ListedXML Sitemap Validator is a free Chrome extension built for technical SEO professionals, SEO agencies, developers, website owners, and digital marketing teams who need a fast way to validate and audit XML sitemaps.
An XML sitemap may be correctly formatted while still containing URLs that return 404 errors, redirects, server errors, timeouts, or other unexpected HTTP responses. XML Sitemap Validator helps you identify these issues without manually checking sitemap URLs one by one.
The extension allows you to validate XML sitemaps and inspect the URLs contained within them. It checks URL responses and helps identify common technical SEO issues that can affect sitemap quality and website maintenance.
Key features include XML sitemap validation, URL status checking, 404 detection, redirect detection, 5xx/server error detection, timeout detection, sitemap URL analysis, and CSV export for further analysis.
XML Sitemap Validator is useful for technical SEO audits, website migrations, sitemap maintenance, website health checks, and recurring SEO workflows.
SEO professionals can use it to quickly investigate whether URLs submitted through an XML sitemap are actually responding as expected. Developers and website owners can use it to identify broken or problematic URLs that may need to be removed, corrected, redirected, or investigated.
The extension is designed to provide a lightweight sitemap-focused workflow directly in Chrome. It can complement larger SEO crawling and auditing tools when you need a quick way to inspect sitemap URLs without running a complete website crawl.
Whether you are auditing a small business website or reviewing a large XML sitemap, XML Sitemap Validator provides a convenient way to validate sitemap URLs and identify potentially problematic responses.
The extension is free to use and available through the Chrome Web Store.
