Website Usability Testing: all you need to know


Owning an attractive website is very important. Recent studies have shown that Aesthetics brings credibility to the website, meaning providing user experience is key. To achieve this, you need to conduct website usability testing.

This article will explain what usability testing is and how it works.

What is usability testing?

Usability Testing is a series of actions to test how easy the website is to use from the perspective of the end user.

This test involves a representative group that will provide feedback on site quality. The more problems you find, the more improvement you need.

Not only that, most people come to the site because of specific needs. For example, book a ticket or find a piece of information. They often spend very limited time doing that. If your website does not meet those needs easily and quickly, they will move on to another site.

When focusing on delivering the best user experience, usability testing should cover the entire development process of creating websites. To do this, usability testing should take place:

  • Before making any design decisions
  • When you need to understand the customer during the development process
  • When there are conflicting opinions about the design
  • When you need to evaluate everything after launch

In short, you perform usability testing during the "brainstorm" stages, prototyping and evaluation.

During each testing phase, participants will work with experts. They are called Researcher UX and Designer UX - who will be responsible for the whole usability testing process.

Depending on the type of test, there may be unregulated testing. (We will talk a little more about usability testing later)

In general, usability testing is designed to require participants to perform certain tasks and note down findings.

For example, you can ask a participant to book the cheapest one-way flight from JFK International Airport in New York to Heathrow International Airport in London on a specific date. Then see how the process goes smoothly.

There are basic parameters used to perform usability testing. The researchers not only easily collect the results but also improve the accuracy of the results.

User friendly

If your website is well designed, there will be many participants completing the assigned task without any difficulty.


The less time it takes to complete a task, the better your design.


Very clearly, web developers will fix errors before completing the project. In addition, during testing, participants will help you spot grammar or design errors quickly.


If participants complete tasks but make complaints, you must improve your level of satisfaction.

What are the common types of usability testing?

There are many types of usability testing, but we would like to mention the three most relevant ones.

Usability Testing In-Person or In-House

This type of usability test is performed on-site, controlled and observed by researchers.

Although the participant may be your employee, hired to perform the test, it is better if you use the new person to get unbiased results.

There are several common techniques for this type of usability test:

  • Eye tracking - shows where participants are looking on a page
  • Card sorting - Good for constructing structure and navigation or labeling
  • A / B testing - Good to compare the two designs

Remote Usability Testing has no control

This type of usability test is not directly and is not controlled by the researchers to handle the problem.

Using this method, you can use your own tools online and reach the many participants you need from around the world. Not only can you get results faster, but this test will also be most convenient for participants.

There are many online services that will help you conduct such tests. With eye tracking, you can try Gazepoint or RealEye to collect data on what people see via webcam.

For card sorting test type, Optimal Workshop can help you learn how participants organize content. And with A / B testing, you can try it out Convert and VWO to handle testing.

Usability Testing remote controlled

This type of usability testing is a combination of direct and unregulated remote testing.

The benefit of conducting this type of test is that you can get high quality results quickly. Meanwhile keep the participants feel comfortable.

If you do not have the best tool for remote testing, you may encounter ambiguous results. On the other hand, direct testing may take longer to achieve more results.

For this type of usability test, you can try Loopback or more advanced Userlytics.

These three types of usability testing methods have their own advantages and disadvantages, so you should choose the best one for your website.

Now, let's continue learning how to do usability testing.

6 steps to conduct Website Usability Testing

Have 6 step To perform the site usability test:

Step 1 - Determine what parameters need to be measured

At the outset, you need to clearly define what you want to achieve when testing, and what your website goals are.

For example, you just want to know how users will successfully book tickets? Or do you want to learn if the new design improves the user experience?

We always advise people to test only one thing at a time. But it is more important to define the target so that you can measure the test well.

Step 2 - Determine the best method

As we mentioned before, the method you use to test usability is very important.

If you want to run a series of tests involving the same person, you can run the test directly on the spot. But, if you want quick, yet high-quality results with participants from around the world, you can use a controlled remote usability test.

The loopback is great for checking website usability

For example: with Loopback, you can create links for participants to access. You can then ask them to install the application and start testing. You can let testers do what they want, but you still have control over the parts that need to be tested or control the action taken.

Step 3 - Create a scenario for the task and set the success rate

The scenario for this task is similar to what we mentioned earlier about booking the cheapest one-way flight on a given day.

When you set the scenario, you need to determine your success rate.

If you want to find finding the right booking page as an index, you need to determine if all four of the boxes must always be true or still accept errors in one of those boxes.

In addition, you can take the time limit for completion as an indicator of success.

Step 4 - Find participants

The usability testing you perform must be efficient and productive. That is why finding the right participants is a very important factor.

Usually, common, normal, five participants is the ideal number for each test session. Because of easy management, no cost compared to third parties. However, depending on the stage of development and testing methods will determine the number of participants.

For the initial development stage, you can use Hallway method. This method is to randomly select people to test their website. With this method, you may not need to research the ideal user first.

On the other hand, at a later stage of development, if you select participants who are close to your user persona, you can produce more accurate results. User persona is a model that reflects users actually including their characteristics, needs and goals.

Step 5 - Conduct testing

Although you can use random participants, you should not use as many arbitrary techniques for a test session.

When conducting tests, the tasks and order should be consistent - even for uncontrolled remote testers. It is also helpful to send clear and concise instructions to participants.

You can tell the test time, how they comment on the findings, and the goal of the test.

Step 6 - Analyze and report results

Depending on the type of test, you can summarize the findings and organize the report according to your goals. You can analyze the results by method analysis calculated or correlated.

If you do website usability testing yourself, you can create one Map of customer directions. This is important to get valuable information. It helps you look at it from a user perspective.

Another method is to use spreadsheets to categorize things like pros and cons, big and small problems, normal and important issues, etc. This will help you easily plan any improvements to the site.

If you use a third party service, you can choose the type of results you will receive.


Website usability testing is very important for your company. It can help to best design and focus on the user experience.

There are three types of usability website tests that you can choose, based on your needs and goals. Detail test usability in-person or in-house, usability test No remote control and Remote usability testing is under control.

After selecting the method, you can perform the usability test with 6 steps after:

  1. Determine what to measure
  2. Determine the best method
  3. Create scripts for tasks and set success rates
  4. Find participants
  5. Carry out the test
  6. Analyze and report results

Now, there is no longer any reason to make a website for a bad user experience. Let's perform website usability testing right away!
