An HTML (Hypertext Markup Language) sitemap is a page (file) that collects and lists all the important pages of your website. It is a bulleted outline text version of the full site navigation. An HTML sitemap allows site visitors to navigate a website easily. HTML sitemaps opposite to XML sitemaps are accessible on the website, usually on a dedicated page. The HTML sitemap includes every page on the website – from the main pages to lower-level pages and a clickable list of pages.
Website visitors can use the Sitemap to find and locate a page or other type of content or topic they cannot find by searching the site or navigating through the site menus. HTML sitemaps are currently not very popular, especially on big websites with thousands of URLs. From a user perspective, it can be hard to navigate very long sitemaps that contain thousands of anchors with links. Finding something on such a page can be a big challenge.
There are two main types of sitemaps: HTML and XML. Hypertext markup language (HTML) and Extensible Markup Language (XML) are two coding languages used to create web pages.
