A sitemap is a file that includes the different pages of an Internet site and the way to them through the sections of the Internet site. The web pages can be sorted visually or as simple text and this type of a file is quite useful for two reasons. The first is that it makes it a lot easier for the website visitors to discover a specific page they need, so that they can navigate your website better and faster, which in turn will improve their user experience and it will be more likely that they will revisit the website or will recommend it to other people. Another reason is the fact that a sitemap enables search engines to index your content better, particularly when it's updated, so when users are looking for certain content, it is more likely that they will come across your site as it will be listed higher in their search results. In case your site is not indexed efficiently, 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.
