Free Sitemap Tester

Our sitemap tester probes a sitemap end to end the way Googlebot would. Enter the sitemap URL and we issue two parallel fetches (a regular browser user-agent and the Googlebot user-agent) plus a robots.txt fetch, then report a structured pass / warn / fail per delivery check: HTTP status code, redirect chain length, response time, Content-Type header, gzip or Brotli compression, file size against Google's 50 MB cap, XML declaration, parse success, Googlebot vs browser response divergence (CDN cloaking), robots.txt allowance for Googlebot, and whether your robots.txt declares the sitemap.

This tool is different from the Sitemap Validator. The Validator parses the XML inside the file and reports schema errors. The Tester focuses on the DELIVERY layer: did the server respond correctly, can Googlebot reach it, is it behind authentication, does a CDN return a different body to bots. Both answer "is my sitemap broken?" from different angles.

For SEOs

Our tool surfaces the bot-only failures that hide from a normal browser, so you can:

• Catch a WAF that returns 403 only to Googlebot
• Notice a redirect chain that points search engines at a 404
• Confirm robots.txt allows the sitemap path before submitting to Search Console

For Developers

Our tool runs the checks a deploy gate should run, so you can:

• Verify a staging-to-production migration kept the sitemap reachable
• Confirm Cloudflare or your CDN is not stripping the Sitemap: directive from robots.txt
• Smoke-test a new sitemap URL before adding it to your robots.txt

Why Use Our Sitemap Tester

• Googlebot cross-check: We fetch the sitemap with the Googlebot user-agent and compare the first few KB of the response to the regular fetch. A diff surfaces CDN cloaking that is invisible from a normal browser.
• robots.txt awareness: We check whether robots.txt disallows Googlebot from the sitemap path AND whether a Sitemap: directive points at this URL, the two robots.txt facts that actually matter for sitemap discovery.
• Honest pass / warn / fail: Each check has a clear verdict and a concrete fix hint when something is wrong. No fabricated overall score.
