A sitemap is a file which includes the different pages of a site and the way to them through the sections of the Internet site. The webpages can be organized visually or as simple text and this type of a file is really useful for two reasons. The first is that it makes it much easier for the website visitors to discover a particular page they need, so they can navigate your site better and much faster, that in turn will increase their user experience and it'll 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 makes it possible for search engines to index your content better, especially if it is updated, so if users are looking for certain content, it is more likely that they'll come across your website because it will be listed higher in their search engine results. In case your website is not indexed well, it may not show up for some searches, so even if you have what people require, they will simply not get to your Internet site.
