How to properly implement the category structure in WordPress?

Question

Search Engine Optimization

There is a large site-catalog of spare parts. At the moment, the structure in the headings is as follows:
Audi

• 100
  
• 80
  
• C4..
  

bmw

• 3
  
• ...
  

Also separately headings are spare parts:
Spare parts

• Spare part 1
  
• Spare part 2
  
• Spare part 3
  

Accordingly, you can get pages and edit information on them in the format:
site/brand
site/brand/model
site/spare part

How to set up pages like:
site/brand/spare
site site/brand/model/spare part?
Can the structure be altered somehow? We need pages that could be customized.

Answer 1

You make pages according to a pre-created structure and collected semantics. The rest of the pages you create through filters. The key is to avoid duplicates.
