How do you test information architecture?

Card sorting to learn how users group concepts, then tree testing to verify they can find things in the proposed structure — both run on the structure alone, before any visual design exists.

Is information architecture just navigation?

Navigation is the visible tip. IA also covers labels, groupings, hierarchy, and the relationships between content — decisions that shape search, onboarding, and even how the product is talked about.

Information Architecture

The structural design of a product's content and navigation — how information is organized, labeled, and grouped so people can find it.

Process & Methods

Information architecture (IA) is the organizing logic beneath a product: the categories, the navigation, the labels, and the relationships between pages. Good IA matches the user's mental model, so people find what they need without thinking about the structure at all.

IA is expressed in artifacts like sitemaps and navigation schemes, and it is validated with methods like card sorting and tree testing. When IA is wrong, no amount of visual polish saves it — users simply cannot find things, and search becomes a crutch for a broken structure.

In practice

A SaaS product's settings sprawl across five menus; support keeps answering “where do I change billing?” An IA pass runs a card sort with twelve customers — users group things by task (“money stuff,” “my team,” “notifications”), not by the org chart the current nav mirrors. Restructured around those groupings and validated with a tree test, the new nav cuts settings-related tickets and, tellingly, in-app search usage — people stop needing the escape hatch.
