I am working on a new site for a customer and they have already planned out a rough structure of pages for their site which involves substantial duplication of structure, but not necessarily of content.
home |--about-us |--business-area-a |--products |--case-studies |--something-else |--business-area-b |--products |--case-studies |--something-else |--products |--product-1 |--product-2
Note that some products would apply to both business areas. We will probably keep the products together under their own products node/page.
Now, from a user journey point of view I guess it makes sense to be able to select their business type (a or b) then browse appropriate products. However, I want to know if this design, where the structure of content is effectively duplicated, is a bad idea. Would it be better to just have case studies and products as level 2 pages, then tag the case studies and products pages with the relevant business area categories?
