How would you redesign the architecture of a website with thousands of disconnected pages?

Home
 ├── Category
 │    ├── Subcategory
 │    │    └── Product
 │
 └── Resources
      ├── Topic
      └── Article

Then identify:

• primary entities;
• categories;
• supporting content;
• commercial pages;
• informational pages;
• geographic pages.

Build contextual internal links between related entities.

Do not simply add a "related pages" block everywhere. Internal linking should communicate meaningful relationships.
