Taxonomy Review
A practical information architecture method for auditing an existing taxonomy and improving the parts that create confusion, inconsistency, or poor findability.
How to use taxonomy review to assess an existing structure, find where it breaks down, and improve categories, labels, and hierarchy without starting again.
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 review is a UX and IA method used to assess how well an existing content or product structure performs.
It focuses on evaluating categories, glossaryHierarchyHierarchy is the organisation of elements to show importance and guide user attention.Open glossary term, labels, and relationships to identify gaps, inconsistencies, and areas of confusion.

The goal is to make the existing 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 clearer, more consistent, and easier to navigate.
Taxonomy review is most useful when the structure already exists, but users are still struggling because that structure is no longer working clearly or consistently.
When to use it
Use this method when you already have a structure but it’s underperforming.
It is most useful when:
It is less useful when:
Taxonomy review is often used before taxonomy redesign or optimisation work.
Key takeaway
Use taxonomy review when the structure is already there, but you need to understand why it is failing before deciding how much to change.
How to run it
Set up properly
Be clear on which parts of the 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 are in scope, what glossaryDataData is raw, uninterpreted information collected and stored so it can be analysed, processed, or used to inform decisions. On its own it carries no meaning; context and interpretation are what make it useful.Open glossary term you have, and what a good outcome looks like. Reviewing everything at once produces a list nobody can act on.

It relies on indexing, metadata, and relevance algorithms to return useful results.Open glossary term glossaryDataData is raw, uninterpreted information collected and stored so it can be analysed, processed, or used to inform decisions.

Run the method
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 review is analytical and structured. Unlike designing one from scratch, you are diagnosing a glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term that is already carrying live content and live glossaryBehaviourBehaviour refers to how users interact with a system, including actions, patterns, and responses.Open glossary term.
- Audit the existing structure and categories as they are actually populated, not as the documentation describes them.
- Identify inconsistencies and overlaps: categories that duplicate each other, or that were clearly added under pressure.
- Analyse real glossaryNavigationNavigation is the system of menus, links, and cues that lets people move through a product and reach what they need. It exposes the underlying structure, and is how most users experience that structure.Open glossary term and glossarySearchSearch is the functionality that allows users to find content or information by entering queries.

Where people route around a category, it is not working.
- Review labels and terminology for drift. 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 decay through well-meant additions more often than through bad initial design.
- Highlight gaps and redundancies, and separate the two. A gap needs content; a redundancy needs a decision nobody has wanted to make.
Focus on how the 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 performs in practice. A structure can be logically immaculate and still fail every task put through it.
Capture and make sense of it
The value comes from identifying breakdowns. Look across the findings to identify:
- Categories that confuse, attract everything, or attract nothing
- Duplicated or overlapping content, and which glossaryVersionA version is a specific iteration of software or a product at a point in time.Open glossary term people use
- Gaps where real user needs have no home
- Misalignment between the structure and observed glossaryBehaviourBehaviour refers to how users interact with a system, including actions, patterns, and responses.Open glossary term
Use this to inform improvements. A review earns its cost when it produces a prioritised set of changes, not a critique of the current state.
