A sitemap (sometimes site map) is a list of the accessible pages on your website. Sitemaps typically exist in one of two different formats: XML and HTML. Generally, XML sitemaps are used to help search engines crawl a website, whereas HTML sitemaps are used to help visitors to a site see how the site is organized.
An XML sitemap is used to tell search engines what pages are on your site, how they are organized, which pages are most important, and how often each page is updated.
You can find the XML sitemap for your website by visiting www.yoursite.com/sitemap.xml (or yoursite.jimdo.com/sitemap.xml). Submitting this sitemap to search engines is an important step in optimizing your site for search.
By default, pages that are hidden in your Navigation will not show up in the XML sitemap. If you would like to include hidden pages, click Settings > SEO > XML Sitemap, check the box, and click Save.
An HTML sitemap helps visitors to a website learn about the site's structure, i.e. where various pages are located on the site. Jimdo automatically creates an HTML sitemap for you that can be found at www.yoursite.com/sitemap (or yoursite.jimdo.com/sitemap). You can also choose to link to the HTML sitemap in the footer of your website.
If someone tries to visit a page on your site that does not exist (for instance, by entering yoursite.com/asdfjkl in the address bar) they will be shown your site's HTML sitemap so that they can easily find the page they were looking for.
