Website usability testing: How to run it, what to measure, and best practices

A website can look polished and still create friction when real users try to sign up, make a purchase, find information, or get in touch. Website usability testing helps you see where people hesitate, get confused, or drop off, so you can fix issues before they hurt conversions.

Here’s our comprehensive guide to why and how you should run live website testing—plus our best practices for gathering actionable user feedback.

Live website usability testing helps you find and fix usability issues on your active website before they affect conversions, engagement, or customer satisfaction. It shows how well your site supports the actions that matter most to your business, from product discovery to checkout, sign-up, or lead generation.

And since the test runs on your live website, participants interact with the same content, navigation, page speed, forms, and flows your visitors already use. This gives you more practical feedback than testing in a controlled prototype alone.

This matters as more teams move toward continuous research. In our Maze Future of User Research 2026 report, teams highlight surveys (77%), usability testing (75%), and moderated interviews (71%) as core methods as they move toward more continuous, always-on research.

The biggest benefit of testing live websites for usability is the ability to react quickly, meet evolving user needs, and identify problems early on. By regularly assessing your site post-launch, you can be continuously informed by data.

Testing your live website is also beneficial to:

Live website usability testing works best when you have a clear process for what you’re testing, who you’re testing with, and how you’ll use the findings. Here’s our tried-and-tested process to follow when performing usability tests on your live website:

Start by defining clear objectives for the study. These objectives sit under your broader usability testing plan, and they describe what you want to learn about your website’s user experience in this round of testing.

First, decide what you want to test:

Next, make your objectives specific and measurable instead of vague. For example, instead of “See what people think of our website,” you might set an objective like “Identify usability issues that prevent first‑time visitors from completing the ‘add to cart’ and ‘checkout’ tasks on mobile.”

Another example is “Validate whether people in our target audience can find pricing information in under two minutes on the redesigned pricing page, using remote usability testing.”

The overall goal of every usability test is to validate how easy it is to use your website, but each study should have detailed goals that point to specific questions and metrics. These can be quantitative or qualitative in nature. For example:

As part of your usability testing plan, once you have a clear outline of your goals, you neeed to choose the right usability testing method for your needs (we go into this more in chapter five ).

For each usability test, you’ll need to make three key decisions:

If you're running your usability test in person, you need to choose a location for. the test. However, if you're running remote usability testing, you need to choose a usability testing tool that suits your research and product team needs. If you’re running remote live website tests, Maze helps you capture both quantitative metrics and qualitative feedback so you can see what users do and prioritize improvements with your team.

Ideally, you need website testing features like:

Maze’s live website testing is built for this type of research on live flows, features, and experiences. You connect your website to Maze, define the task you want people to complete, and Maze overlays a small widget on your site to guide participants through it while capturing their behavior and responses.

Depending on how you integrate Maze with your site, you can also unlock analytics like heatmaps, path visualizations, and usability scores, alongside screen recordings and qualitative feedback in one place.

To get started quickly, you can use templates such as test live website navigation or validate sign-up funnels to structure common live website tests in just a few clicks.

Recruiting test participants who are willing to test your product can be challenging. But to gather valuable insights, it’s crucial you get this step right—and if you’re testing frequently, your bank of participants will always be growing.

Here are some ways to recruit participants:

If you’re using Maze for running remote and unmoderated tests, you can add in-product prompts to recruit participants directly from your live website. These prompts appear as targeted popovers on your site and invite visitors to take part in a study while they’re already browsing.

You can also hire participants through the Maze panel with 400+ filters across 130+ countries, including B2B and B2C participants, and add custom screening questions to make sure participants meet your study criteria.

However you recruited participants, you’ll need to ensure you have a clearly-defined user persona to start running screeners. You can do that by:

It’s worth keeping track of your participants and categorizing them, so you can easily invite them to future tests.

Well-written tasks are one of the most important parts of a usability test, because they guide participants through the study and determine the quality of insights you’ll get from their behavior. Create usability test scenarios that are tightly linked to the test goals and mirror real use cases for your product.

For example, you may ask participants to:

Share as much detail as you can, but don’t solve the task for them. This means adding accurate descriptions or gift card codes, not writing: “Go to the accessories tab and click on the first product in the fourth row.”

If you’re running moderated qualitative tests, you should also ask participants about how they’d do certain tasks, and what they found frustrating or difficult. Make sure these are open-ended questions.

Once your tasks and questions are ready, you need to configure the test that your users will see and make it available to participants. In Maze, that means choosing your study type, adding your live website URL, and adding the tasks, questions, and success criteria you defined in the previous steps.

When you launch the study, let participants work through the tasks without stepping in. Maze will automatically record their paths, clicks, and task completions and can generate heatmaps, path visualizations, and screen recordings depending on your setup.

You can also share the test link with recruited participants or place it directly on your live site using in-product prompts. From there, Maze collects their behavior and responses while they complete tasks in their environment.

As you watch live sessions or review recordings, note specific moments you’ll want to return to during analysis, such as:

Once you’ve run your tests, review the results with your original goals in mind. Start by looking for patterns across sessions, not one-off moments. A single participant getting stuck might be useful context, but repeated friction usually points to a common usability issue.

Look for signals such as:

Once you’ve identified these patterns, group your findings by theme. For example, you might see issues around navigation, checkout flow, form design, page speed, or unclear messaging. This makes it easier to separate isolated feedback from recurring problems your team should prioritize.

If you’re using Maze, every live study with at least one participant gets an automatically generated UX report, including website tests. These reports show key metrics at a glance. You see usability scores, completion rates, time on task, misclicks, and mission outcomes such as direct success, indirect success, and unfinished tasks.

For website tests specifically, you also get a mission overview with usability metrics like success rates, average duration, and a navigation view of the paths people took through your site. This includes a Sankey-style flow view that makes it easy to see how participants move toward success or drop off.

Testing your live website for usability is a best practice in itself. But if you want to do it right, here are some tips to keep in mind:

Avoid using technical language in your test scenarios—make it easy for your participants to understand and follow what you’re asking. For example, instead of saying “Create a user account using any form of external authentication (not your email),” say “Sign up using your Facebook or LinkedIn account.”

Also, ensure you’re asking for something that’s actually possible. If you’re only inviting them to sign up using Facebook, but they don’t have a Facebook account, you’re just going to frustrate participants and limit your insights.

Invite your participants to think aloud as they work through the test. Then, you can listen back to the recording and spot exactly what their thought process was to arrive at their solution. For example, you may hear a user say: “I couldn’t find the sign-up button on the home page, but I’ve noticed that sometimes there’s a link to create a new account on the log-in page. So, I’m clicking on the log-in page to see if I can find it there.”

You’ll get richer insights from this, combined with quantitative data like clicks and heatmaps, than you would from the data alone.

It’s tempting to jump in and show participants where to click when they struggle, but that hides the very problems you are trying to uncover. When you rescue someone too quickly, you also introduce cognitive bias. They look to you for hints, and their behavior reflects what they think you want, not how they would use the site alone.

Instead, remind participants that it’s okay to be confused, ask them to keep thinking out loud, and watch how they try to solve the problem on their own. Their struggle often reveals unclear labels, hidden actions, or navigation gaps you need to fix, and it helps you avoid framing or leading them toward a correct path.

Do not assume that ‘participants completed the task’ means ‘the experience was good.’ Someone can successfully check out, update their details, or reset a password and still feel stressed, confused, or annoyed along the way.

For each key task, track what participants did and how they felt about it:

Leaving usability testing until right before launch is risky and, typically, costly. When teams only test at the end of a project, they often end up fixing issues in production or rushing through redesigns under pressure.

The best time to conduct usability tests is at several points in your product lifecycle: early in discovery to validate ideas, on wireframes and prototypes to catch friction before you build, and on your live website to check that real users can complete key tasks.

You should try a mix of test types. While both quantitative and qualitative insights offer value, the most value comes from a combination of the two. One type of data provides context for the other.

For example, ask questions to humanize your quantitative data and truly understand your audience’s thinking process, or analyze test statistics to give numerical weight to qualitative feedback.

You might think that skipping usability testing is a way to save time and money. However, it’s quite the opposite.

When you push features to production, you need to be in a position to catch issues or inconsistencies early on and later down the line as problems pop up. Testing regularly with a live site is the only way to ensure your website is always performing as needed and serving a truly user-centered experience.

Maze helps teams run live website tests as part of a broader research workflow, alongside prototype testing, surveys, AI-moderated interviews, and reporting. With Maze, teams can recruit the right participants, collect qualitative and quantitative feedback, and use AI-powered analysis to identify patterns, summarize findings, and share insights with stakeholders.
