What you mean by site map
A sitemap is structured documentation of the links or pages that a web page contains. We keep track of all the sub-pages of the website. Usually, sitemaps are stored as an XML file as sitemap.xml, which contains metadata of the page as well. These metadata include URL, last modified timestamp, and other useful information which search engines and site crawlers can make use of. It helps them to track the website better and in turn, the website gets a higher ranking for SEO.
The sitemap can be useful for the users as well if it's documented as an HTML file, provided with hyperlinks to subpages. It can make the user aware of the hierarchical structure of the website. These HTML files however will not contain meta-information about the subpages since they are not required for the user.
Even though sitemaps do not guarantee full coverage of crawler bots, it helps the search engines to track the content better. The subpages might have dynamically generated URLs for websites that aren't static. Google introduced Google Sitemaps to tackle this situation. Though it is introduced by Google, it is not limited to Google.
