We are going to cover what website usability testing is, when do you need it, what is the process of preparing the study and some of the best practices to keep in mind.

What is website usability testing?

Website usability testing is a method of evaluating the usability of your website, that is if users can achieve their goals, do so efficiently and to their satisfaction. Modern usability testing also includes some degree of evaluating the user experience as a whole. There are various usability testing methods you can choose to perform such study.

The purpose of testing the usability of a website is to identify usability and UX issues on your website by observing how users interact with it. Using online tools for website usability testing is highly popular, because it is effective, simple to set up, and can be completed in a rather short amount of time when using a good usability testing tool like UXtweak.

When do you need website usability testing?

It’s better to perform several rounds of usability testing during your website design and development process. This strategy will assist you in identifying usability issues early on, allowing you to devote more time to resolving them. 

You can start with testing your high-fidelity prototype before you hand it out to the development team. The next rounds can be performed  before the launch of the website. We also recommend including the “preventative” usability tests in your website maintenance routine. This way you will be able to uncover the rising usability issues early on and always stay up to date. 

Other great opportunities are before and after a redesign, or on additions of new pages or features.

Best practices for website usability testing

1. Pilot the study before the launch

In order to save yourself the time and money on fixing future issues, double check if your study is working as intended by running a “pilot” version of it. Ask a colleague or a friend of yours to complete the test before it goes live. Alternatively, use UXtweak’s Preview feature to see how your study will look like from the tester’s point of view. 

Make sure the tasks lack bias, the wording is clear and everything works smoothly. Running a pilot of the study will also help you estimate the average time needed to complete the test.

2. Prioritize the issues

You’ll probably obtain a solid number of insights from your usability test, but not all of them will be equally severe. Prioritize the most important issues and start your improvement journey from there. Ranking usability problems as low, medium or high severity will help you find out which ones need to be solved right now and which ones can wait. 

For example, users not being able to log in to your app is a high severity problem whereas the text or a logo that are too small can be classified as low or medium severity.

3. Ask good questions

In order to get useful insights, it’s important to know the correct way to formulate your usability testing questions. Make sure they lack bias and assumptions, so that the respondents are not influenced with your wording in any way.
