A sitemap is a file where web pages are listed. The sitemap helps visitors find what they are looking for and Search Engine web crawlers like Googlebot to more intelligently crawl your site.

Also, the sitemap can provide valuable metadata associated with the pages listed in that sitemap: Metadata is information about a webpage, such as when the page was last updated, how often the page is changed, and the importance of the page relative to other URLs in the site.
