Frequently asked questions
Does it support sitemap index files?
Yes. If the root is <sitemapindex> it validates the index and lists every nested sitemap URL it references.
What does it check on each URL?
That every <url> has a required <loc>, and that any <priority> (0.0–1.0), <changefreq> (always…never) and <lastmod> (W3C datetime) values are valid.
Is there a size limit?
Sitemaps are read up to 5MB, which comfortably covers the 50,000-URL protocol limit for a single file.
