Our Sitemap Checker validates your sitemap's structure and flags common issues, so you can confirm search engines are actually able to read it correctly.

Who Uses a Sitemap Checker?
Anyone managing a site's SEO health needs to know their sitemap is actually functioning the way search engines expect, not just that the file exists.
SEOs : auditing technical SEO health before a site launch or migration
Developers : confirming an auto-generated sitemap built correctly
Site owners : verifying their sitemap after a CMS or platform migration
Agencies : running technical audits for client websites
Webmasters : troubleshooting why certain pages aren't getting indexed
How Sitemap Checking Helps Your Website
A sitemap that search engines can't properly parse means some or all of your pages may be getting overlooked entirely, regardless of how good the content on them is.
- Ensure Full Site Discovery
- If your sitemap has structural errors, search engines may skip it entirely, meaning newer or less-linked pages might never get discovered through normal crawling. A clean sitemap is the fastest path to full site discovery.
- Confirm Listed URLs Are Actually Live
- A sitemap listing pages that return errors wastes crawl budget and signals poor site maintenance. Cross-check key URLs with our HTTP Status Checker to confirm everything in your sitemap actually resolves with a 200 status.
- Pair With Your Robots.txt File
- Your sitemap and robots.txt file should work together, not contradict each other. Use our Robots.txt Checker to confirm you're not accidentally blocking crawlers from pages you've listed in your sitemap.
- Catch Issues After a Migration
- Sitemap errors are especially common after a domain change, CMS migration, or URL structure change. Running a check immediately after any major site change catches problems before they affect indexing.
Frequently Asked Questions
1. What counts as a sitemap error?
Common issues include invalid XML syntax, missing required tags like <loc>, URLs that don't match your site's actual domain, an inaccessible sitemap URL, or a sitemap exceeding the 50,000 URL / 50MB size limit set by sitemap protocol standards.
2. Do I need a sitemap for search engines to crawl my site?
No, search engines can discover pages through links alone. But a sitemap makes discovery faster and more complete, especially for larger sites or pages with few internal links pointing to them.
3. How often should I check my sitemap?
It's worth checking after any major site change — a migration, CMS switch, or bulk URL update — and periodically as part of routine technical SEO maintenance, even if nothing has obviously changed.
4. Can I check a sitemap index file that references multiple sitemaps?
Yes, sitemap index files are supported. The tool will check the structure of the index file itself; individual sitemaps referenced within it should be checked separately.
5. Does this tool store the sitemap URLs I check?
No. Your sitemap URL and the check results are shown in your session only — nothing is saved or logged on our servers.
