Sitemap.xml Inspector
Paste a sitemap.xml URL — get URL count, section breakdown, freshness, and issues. Handles sitemap index files recursively. SSRF-guarded.
Frequently asked questions
What does this tool actually check?
Total URL count, child sitemap count (if it's an index), URLs grouped by section, the most recent and oldest lastmod dates, the count of entries missing lastmod, and obvious issues (over 50k URLs, broken fetches, wrong content-type).
Why does Google care about lastmod?
Google uses lastmod to decide what to recrawl. An accurate lastmod tells Google 'this page changed' so it recrawls and re-indexes. Missing lastmod forces Google to use other signals — slower indexing of updates.
What's the maximum size of a sitemap?
50,000 URLs per sitemap, 50 MB uncompressed. Beyond that you must use a sitemap index file pointing to multiple child sitemaps.
Does this work with sitemap index files?
Yes. The inspector recursively fetches each child sitemap listed in an index file (up to depth 3) and aggregates the totals across all of them.
Why was my private/localhost URL rejected?
We block private network hosts (localhost, 10.x, 192.168.x, etc.) as a server-side request forgery (SSRF) defense. Public URLs only.
