It directly affects how users understand and navigate a product.Open glossary term is one of the most common causes of confusion.
The goal is to ensure that terminology is clear, intuitive, and aligned with how users think.

It is less useful when:
Label testing is often used alongside card sorting, tree testing, and findability testing.
Key takeaway
Use label testing when the main problem is not where things are placed, but whether the words used to describe them make sense to users.
How to run it
Set up properly
Be clear on which labels you are testing, what you expect people to understand by them, and what counts as a correct interpretation. Testing labels without a defined meaning produces opinions rather than findings.
Present labels in a realistic glossaryContextContext is the set of surrounding conditions that shape how someone behaves and decides, including their goal, their environment, their time pressure, and what happened immediately before.

Avoid leading or explaining. The moment you clarify what a label means, you have taught the participant the thing you were trying to measure.
Capture and make sense of it
The value comes from understanding interpretation. Look across glossaryResponseA response is the data or result returned by a server after receiving a request.Open glossary term to identify:
- Labels consistently understood as something other than intended
- Ambiguity, where different people read the same word differently
- Gaps between your terminology and the words people volunteered

Use this to refine wording and structure. Where a label keeps failing, the problem is often the category behind it rather than the word in front.
