SITEMAPS & CRAWLING
Sitemap Index Analyzer
Large sites split their URLs across many sitemaps listed in one index. A single dead or malformed child file can hide thousands of URLs from search engines without anyone noticing. This analyzer opens the index, then each sitemap in it.

HOW IT WORKS
How to use the Sitemap Index Analyzer
The URL of a sitemap index file.
Enter the sitemap index URL (often /sitemap_index.xml or /wp-sitemap.xml).
Look for sitemaps that fail or report problems.
Fix or remove those entries, then resubmit the index in Search Console.
WHAT IT CHECKS
What it looks at, and how to read it.
A table of the child sitemaps with status, type, URL count, newest lastmod and problems, plus checks on the index itself.
What it checks
- Child sitemaps that cannot be read
- Indexes listing other indexes (not allowed)
- Child sitemaps on another host
- Bad URLs, duplicates and lastmod problems in each child
How to read the results
- Empty child sitemaps are harmless but often mean a content type is listed that should not be.
- A newest lastmod far in the past on an active section suggests the generator is not updating dates.
GOOD TO KNOW
Common mistakes, an example and the limits.
Common mistakes
- Submitting each child sitemap separately and forgetting to remove dead ones.
- Pointing the index at http:// child URLs on an https site.
A worked example
A WordPress index lists a users sitemap with author archives the site has set to noindex; removing it from the sitemap keeps it consistent.
Limitations
- Reads the first 10 sitemaps the index lists.
- Counts and dates come from each file as served now; a CDN may serve an older copy than your server has.
