Taxonomy Design
A practical information architecture method for creating clear, scalable structures that organise content in ways users can actually navigate.
How to use taxonomy design to create categories, relationships, and naming systems that make content easier to organise, scale, and find.
What it is
glossaryTaxonomyTaxonomy is the system used to classify and organise content into structured categories. It defines how content is grouped, named, and related within a product or system.Open glossary term design is the glossaryProcessA process is a defined sequence of steps used to achieve a specific outcome.Open glossary term of organising content, products, or information into a clear, logical structure.

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

The goal is to create a glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term 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:
Taxonomy design is often informed by card sorting, tree testing, and analytics.
Key takeaway
Use taxonomy design when you need to create a durable structure that can support navigation, labelling, search, and growth across the whole system.
How to run it
Set up properly
Be clear on what needs organising, what people are trying to do with it, and what glossaryConstraintsConstraints are limitations or restrictions that impact how a product or solution can be designed or built.Open glossary term you are working inside: existing glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term, editorial capacity, legacy URLs.

- Audit what exists before you categorise anything. You cannot design a structure for content you have not counted.

- Whether the glossaryHierarchyHierarchy is the organisation of elements to show importance and guide user attention.Open glossary term is shallow enough to navigate confidently
- Whether labels are clear, consistent and free of internal language
- Whether the glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term absorbs new content without a special case
