What is the Sitemap Checker?
The Sitemap Checker validates an XML sitemap and reviews practical health signals such as URL count, XML format, last modified values, duplicate URLs, redirects, and broken pages. It helps you catch sitemap issues before they affect crawl discovery.
A sitemap does not guarantee indexing, but it helps search engines discover important URLs and understand when pages have changed. A messy sitemap can waste crawl attention on duplicate, redirected, or broken URLs.
Why Sitemap Health Matters
Search engines can find pages through links, but a clean sitemap gives them a reliable list of URLs you consider important.
Improves discovery
Sitemaps help search engines find important pages, especially on large or newer sites.
Reduces crawl waste
Removing broken, redirected, and duplicate URLs keeps the sitemap cleaner.
Supports freshness
Accurate lastmod values can help crawlers understand when content changed.

XML Sitemap Best Practices
Include only canonical indexable URLs
Your sitemap should list the URLs you actually want search engines to crawl and index.
Remove broken URLs
404s, server errors, and blocked pages do not belong in a production sitemap.
Avoid redirect chains
List the final destination URL, not an old URL that redirects elsewhere.
Keep lastmod honest
Only update lastmod when meaningful page content changes, not on every page view or rebuild.
Split very large sitemaps
Large websites should use sitemap indexes and separate sitemaps by content type where useful.
Declare the sitemap in robots.txt
A Sitemap directive in robots.txt gives crawlers another way to discover it.
