Quick take

If your content is messy or hard to navigate, fix the structure with taxonomy design.

What it is

design is the of organising content, products, or information into a clear, logical structure.

It defines how things are grouped, labelled, and related to each other across a .

This includes categories, subcategories, tags, filters, and naming conventions.

Unlike card sorting or testing methods, design is about creating the structure itself, often informed by and .

The goal is to create a that is easy to navigate, scalable, and aligned with how users think.

Taxonomy design is most useful when the problem is not just confusing labels or broken paths, but the lack of a coherent structure underneath the whole system.

When to use it

Use this method when structure and organisation are critical.

It is most useful when:

It is less useful when:

Content is small or simple
You have not yet understood user behaviour
You need to validate rather than create structure
Taxonomy design is often informed by card sorting, tree testing, and analytics.

Key takeaway
