Information Architecture
Information architecture is the structural decision layer that defines where information lives, in what order, and in what relationship.
The organization of content, page types, and navigation so they make sense for both users and search engines.
Poor information architecture creates friction for users and makes it harder for search engines to interpret pages in the right context.
To make service, blog, work, and glossary content support one another, the information architecture has to be designed from the start.
