Sitemap
Definition
A sitemap is a file—usually XML—that lists important URLs on a site to help crawlers discover pages efficiently.
Full definition
Sitemaps complement internal links; they do not guarantee indexing. They often include lastmod hints and live at /sitemap.xml or are referenced from robots.txt.
For AI and search crawl hygiene, keep sitemaps accurate and exclude non-indexable junk. See robots.txt.
