In order to be able to look at the project as a whole and see how extensive it is, it is useful to create a sitemap. This tool in a hierarchical way visualizes the structure and individual sections of the designed website, which is a solid starting point for building information architecture. Sitemap preparation brings many benefits. From it, we can deduce how structured the navigation should be. It also allows us to decide where the specific content will be located. It shows the relation between individual subpages and is useful during the initial estimation of the development phase. Also, sitemap allows you to plan your SEO well, thanks to the fact that the map shows which the designed website will cover areas in terms of content. Because, in the case of SEO, it is important not to duplicate keywords; therefore, prior preparation of the map helps plan where to place them.
