Why UX testing?
Why should you conduct user experience testing?
UX testing explores how people interact with websites, apps, digital products and services so research teams can identify where the experience works well and where users encounter friction. Participants are typically asked to complete realistic tasks while researchers observe their behaviour and gather feedback.
The method can reveal problems that are difficult to identify through analytics or stakeholder review alone. Researchers can see where users hesitate, misunderstand instructions, abandon tasks or take unexpected routes through a product or service.
UX research can be conducted remotely or in person and may involve moderated or unmoderated sessions. It is useful at different stages of development, from early concepts and prototypes to live products that need refinement.
The quality of UX testing depends on recruiting participants who genuinely represent the intended users. FieldworkHub manages participant recruitment against detailed criteria, helping clients reach relevant consumer, B2B and specialist audiences for usability and user experience research.

Types of UX research
What are the different types of UX research?
Below we describe some of the common ways of undertaking UX testing research.
Moderated usability testing
A researcher observes participants as they complete tasks on a website, app or digital product, asking questions and exploring their reactions along the way. This approach helps uncover usability problems and understand why users encounter difficulties with particular features or tasks.
Unmoderated usability testing
Participants complete predefined tasks independently, usually through a specialist research platform. Their actions and feedback are recorded for later analysis, making this approach useful for testing with larger or geographically dispersed groups of users.
Prototype testing
Participants interact with early versions of a website, app or product to assess its usability before development is complete. Prototype testing helps researchers identify confusing features, evaluate design concepts and make improvements before launch.
User interviews
One-to-one interviews explore users’ needs, experiences and expectations of a digital product or service. Researchers can investigate specific difficulties, understand motivations and gather detailed feedback to inform design and development decisions.
Accessibility testing
Participants with different disabilities or accessibility needs test websites, apps or digital products to identify barriers to effective use. Research may involve assistive technologies, such as screen readers, and helps organisations create more inclusive experiences.
Eye-tracking research
Specialist technology records where participants look when using a website, app or digital interface. This helps researchers understand visual attention, identify elements that attract or distract users and assess how effectively information is presented to, and understood by, the target audience.

1
What is the difference between qualitative and quantitative UX research?
Qualitative UX research explores in detail the behaviour of a small number of participants through methods like interviews and observations. Quantitative UX research is designed to generate numerical data, and often involves A/B testing of different versions of an app or website (or testing of a client app/website against those belonging to competitors), to determine which version performs better.
2
How does UX testing impact product design?
UX research informs design decisions by providing insights into user needs and behaviours. It helps create user-centred designs that improve usability, satisfaction and overall product success.
3
How do you present UX research findings?
Findings are presented through detailed reports, user personas, journey maps, and presentations. These materials highlight key insights, recommendations and actionable steps to improve the user experience.
4
What are personas used in UX research?
Personas are fictional characters representing different user types based on research data. They help designers understand the goals, behaviours and needs of different user segments, guiding design decisions to help ensure that the requirements of key market segments are satisfied.
