The site map is a list of website pages accessible to crawlers or users, presented in a simple and understandable manner. The site map is also important for website promotion, allowing the promoter to replicate instructions on the site’s different content pages, as well as edit the internal links.
Today, it’s common to present the site map in Extensible Markup Language (XML) code, and after creating it, the website promoter will notify search engines about the new website or content so that it can be quickly re-scanned, updating the search engines about the modified website’s hierarchy. There are also separate XML maps for the website’s videos.
