Planning the website involves creating a wireframe and sitemap. This is an important step because it is kind of like the skeleton of your site. This process can take about 2-6 weeks to complete. The sitemap allows the developer to get an outline of what the site will look like, what pages there will be and how they will interact with each other. This not only helps with planning but is also beneficial to the user experience.
A user should be able to easily navigate a site, and this begins with the development of the sitemap. Before you begin to plan content, a sitemap lets you design what the structure will look like. Once the sitemap is completed, the other part of this step is to create a wireframe or mock-up. These are just visual representations of what the site will look like. This does not include the layout details. That comes next.
