Quick take

If your structure exists but isn’t working, use a taxonomy review to fix it.

What it is

review is a UX and IA method used to assess how well an existing content or product structure performs.

It focuses on evaluating categories, , labels, and relationships to identify gaps, inconsistencies, and areas of confusion.

Unlike , which creates structure, a review audits what already exists and improves it.

It typically combines , analytics, and to understand where the structure is breaking down.

The goal is to make the existing 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:

Users struggle to find content or products

Search is being used as a workaround
You are preparing for a redesign or optimisation

It is less useful when:

You need to create a taxonomy from scratch
There is very little content or structure
You need deep behavioural research
Taxonomy review is often used before taxonomy redesign or optimisation work.
