Sitemap
A sitemap is an XML file listing a site's URLs with optional last-modified dates, change frequencies and priorities.
Why it matters
It is how a crawler discovers URLs that internal linking reaches slowly, and how you communicate which pages changed.
How it is measured
Fetch /sitemap.xml and check for duplicates, off-origin URLs and a lastmod distribution that is not one clustered build timestamp.
