“Software alone is no longer a competitive advantage;
great software is.
Great software requires great design”

Usability testing is a process in UI/UX design services in which real users interact with a product to identify issues. One of the benefits of usability testing is to increase your business metrics. This service is designed for companies seeking to improve user satisfaction. One online store used usability testing to identify checkout issues, resulting in a 20% increase in sales. The result: improved UX, higher conversion rates, and a reduction in customer support calls.
Usability testing, being one of the design phases, is one of the research methods of user experience (UX) design. This key UX research method allows evaluating (a) to which extent it is easy to use a product, (b) the specifics of user behavior with the product, and (c) customers’ emotions while using the product. The knowledge gained from usability testing plays a role in the growth of business metrics. In the article, we are going to discover what usability testing is, usability testing benefits for business, and which business metrics it influences.
In 2026, usability testing and UX audit services are vital for digital products. SaaS companies that conduct regular usability audits report faster adoption of new features and increased customer loyalty, which directly improves key business performance indicators.
What is Usability Testing?
First of all, usability testing conducted by UX designers is your secret weapon and one of a few tools (in addition to A/B tests and data analytics) that will allow your business metrics to grow, your product to be successful, and your clients to be loyal. Of course, you don’t need this secret weapon in case you have your own – 100% accuracy of your intuition.
Speaking in academic language, as we’ve mentioned in our article “UI/UX Design for Startups: Effective and Practical Tips”, Usability Testing is a primary form of qualitative user experience research, which is “based on asking a user to complete certain tasks using your product to reveal pitfalls and sticking points in your product that impair usability”.
Benefits of usability testing: usability testing can tell you (a) whether your product is easy-to-use, convenient, and pleasant to use by your target audience; and (b) what should be improved to make your product better for the end-users.
As Paul Maritz correctly noted, usability testing is “about catching customers in the act, and providing highly relevant and highly contextual information”.
It’s very important to differentiate usability testing from user interviews. They have different goals, and you get different information from them. User interview does not require a user to use your product or to look at the design, and doesn’t answer such questions as whether it is easy to use your product/design, why it is easy or difficult to use your product or design, but rather allows you to hear the thoughts of a user regarding the certain topic (colors used, for example), their perception of the topic, which is not based on their behavior or real experience.
There’re several main types of usability testing – (a) formal in-person; (b) informal remote; and (c) so-called guerilla type of usability testing. The main difference is:
- in the level of details and accuracy of the results
- as well as the time
- assets needed to conduct usability testing
The most accurate results can be received from Informal remote testings – users are not so nervous as they would be meeting you in person in the lab conditions which happens during formal in-person testings. Guerilla tests have less accurate results but they are the fastest and cheapest. The benefit of guerilla testing is that you can conduct it with anyone you can reach in a second and in any place – your wife at home, a colleague during their morning coffee, etc.
