An XML sitemap is not a viewable page on a website but a file that contains links to all of the pages on the site. It also includes important information about each page, including the priority of the page and how frequently it is updated. These files can help a search engine’s bots crawl a site more effectively. Each link on a sitemap is like a request for a search engine’s bot to crawl the linked page. Webmasters can submit their XML sitemaps directly to major search engines like Google and Bing.
