What is a XML Sitemap Tester & Validator?
Submit a sitemap URL or paste XML directly. The tester lists each loc entry and checks whether URLs return 200, redirect, or error — helping you fix indexing issues before Google crawls broken links.
Upload, paste, or link a sitemap.xml to validate structure and sample-crawl URLs for 404s, redirects, and robots conflicts — then export actionable SEO findings.

How it works
The sitemap is fetched and parsed for loc tags. Each URL is requested to record status code, final URL after redirects, and timing so you can spot 404s or chains.

Usage scenarios
- GSC “Crawled – not indexed” triage: After a migration, test the live sitemap to find 404s and redirect chains that waste crawl budget before you click Validate Fix in Search Console.
- Sitemapindex rollup check: Paste a sitemapindex that fans out into post-/product sitemaps; confirm nested files resolve and combined URL counts stay under practical limits.
- robots.txt conflict hunt: Catch URLs listed in the sitemap but Disallow’d in robots.txt — classic reasons Google discovers a URL yet refuses to index it.
- Pre-launch QA for 50k URL cap: Large catalogs near 50,000 URLs / 50MB get warnings here so you can split sitemaps before Google truncates silently.
Input / Output Examples

Flagged as redirect hygiene issue — update sitemap to the final canonical URL
Frequently Asked Questions
Why test a sitemap if Google already has Search Console?+
GSC reports outcomes; this tester helps you find concrete URL failures (404, redirect chains, robots blocks) in one pass before you burn crawl/validation cycles.
Does analysis upload my sitemap to FYN forever?+
Parsing is client-first; URL checks use short-lived requests needed to read status codes. Do not paste sitemaps that expose confidential staging hosts you are not allowed to probe.
What health score should I aim for?+
Aim for the high 90s: mostly 200s, minimal redirects inside the sitemap, zero robots-blocked URLs, and no soft-404 patterns. Fix critical broken URLs first.
How are soft 404s detected?+
Some pages return HTTP 200 with “not found” style body copy. The tester flags likely soft 404s so you can remove them from the sitemap or fix the page.
Can I test password-protected staging sitemaps?+
If the sitemap URL requires auth the public fetch will fail. Export XML locally and upload/paste the file instead.
