Why XML Sitemap Health Matters
Google discovers 26% more pages when a valid sitemap is present. A broken or outdated sitemap can delay indexing of new content for weeks — directly impacting your organic traffic.
Index Coverage
Ensure every critical page is included and discoverable. A well-maintained sitemap tells search engines exactly what to crawl and when.
Structure
Validate hierarchy and priority for crawlers. Sitemap indexes, correct <priority> values, and fresh <lastmod> dates all influence crawl scheduling.
- Broken sitemap links cause pages to be missed during indexing
- Missing <lastmod> dates slow recrawl of updated content
- Duplicate URLs confuse crawlers and dilute crawl budget

Frequently Asked Questions
What is an XML sitemap?
An XML sitemap is a file that lists all important URLs on your website, helping search engines discover and crawl your content efficiently.
How does the sitemap validator work?
Enter your domain and we auto-discover your sitemap (from robots.txt or the default /sitemap.xml path). We parse every URL entry, check for valid XML, spot-check for broken links, and generate a health score.
What health score should I aim for?
80%+ is excellent. Below 50% indicates critical issues like broken links, missing URLs, or invalid XML that could hurt your indexing.
Does this check sitemap indexes?
Yes. If your site uses a sitemap index (multiple sitemaps), we detect it and show all child sitemap references.
How often should I check my sitemap?
After any site update, migration, or CMS change. For active sites, a monthly check catches drift before it impacts rankings.
