Creating Categories Hierarchy

Clever thing about WordPress by creating a hierarchy of Categories and assigning them to Posts you build the website’s sitemap automatically.
So you need to be a bit thoughtful about their arrangement.
Remembering that search engines do not want to be chasing moving targets every few years.
Taking the NGS website sitemap as a starting point and adding the GBE Marketing ambitions the website hierarchy has had to evolve.
But the 1800 pages from NGS website need a GBE home so the sitemap is not radically different but evolving from one or 2 roots in place of many.
The thing that does not happen is dropdown menus are not created and developed for you.
Once the hierarchy is complete and Posts have been assigned Categories I will generate the sitemap and turn it into navigationspages.
Posts can be in many categories so can appear in many places in the site map, so cross referencing between Posts with similar topics is less important
But the site can become crowded and could feel a bit repetitive.
