Sitemap Checker

XML sitemap validation

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 it matters

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.

Best practices

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.

Common Sitemap Mistakes

Listing URLs blocked by robots.txt or noindex
Keeping old redirected URLs in the sitemap
Including duplicate URL versions with parameters
Using inaccurate lastmod values
Forgetting to update the sitemap after major site changes
Assuming sitemap submission guarantees indexing

Frequently Asked Questions

No. A sitemap helps discovery, but Google still decides whether a page is worth indexing based on quality, accessibility, duplication, and other signals.

No. A sitemap should list final canonical URLs, not old URLs that redirect.
