What is a sitemap?
A sitemap is a simple outline of a page, that makes it easier to navigate. There are two kinds of sitemaps: HTML sitemaps and human-readable sitemaps.
HTML sitemaps provide information for search engines. They help them identify keywords and index a site in order to improve their search process.
Human-readable sitemaps are aimed towards people visiting the web site. They make the orientation on the site easier and provide information about the key points that can be found on the site.
