Sitemap Health Checker
Paste a domain or sitemap URL. We find the XML, inspect sitemap indexes, sample public URLs, and flag crawler problems without attempting to crawl your entire internet estate.
At a glance
- Discover sitemap references in robots.txt and standard sitemap paths.
- Validate URL sets and sitemap indexes with strict response, redirect, and child-file limits.
- Sample URL status, redirects, host mismatches, HTTP links, and robots.txt conflicts.
What this means
A sitemap is a map, not a guarantee
A valid sitemap helps crawlers discover canonical public URLs. It does not force indexing. This checker verifies that crawlers can find and parse the map, then checks a bounded sample for redirects, failures, and robots.txt conflicts.
How does sitemap discovery work?
We check Sitemap directives in the site's public robots.txt, then try /sitemap.xml, /sitemap_index.xml, and /sitemap-index.xml. A direct XML URL is checked first.
Does this check every URL?
No. The MVP samples up to five URLs and labels that limit clearly. Sitemap files are counted within bounded child-file and response-size limits; this is a health check, not a full crawl.
Why can a valid sitemap still show warnings?
XML validity is only one layer. HTTP URLs, another host, redirects, failed pages, missing robots.txt references, or robots rules that block listed URLs can all make a technically valid sitemap less useful.
Are checked URLs stored?
No. The server fetches public files because browser CORS rules often prevent direct checks. Requests run in memory through private-network, DNS, timeout, redirect, and response-size protections.
