A sitemap is a file which includes the different pages of a website and the path to them through the sections of the Internet site. The web pages can be sorted visually or as simple text and this kind of a file is quite useful for 2 reasons. The first one is that it makes it much easier for the site visitors to locate a particular page they need, so they can navigate your Internet site better and more quickly, which in turn will increase their user experience and it will be more likely that they will return to the website or will recommend it to other people. The second reason is the fact that a sitemap enables search engines to index your website content better, especially if it is updated, so if users are looking for specific content, it's much more likely that they will come across your Internet site because it will be listed higher in their search engine results. If your site is not indexed efficiently, it might not show up for some searches, so even if you have what people want, they will not get to the website.
