Observe Users with Think-Aloud Method
While there are numerous sophisticated tools and metrics available, my preferred method for testing website usability essentially comes down to something fundamental: observing people as they use it. Within this observational approach, one specific technique I rely on heavily is task-based usability testing with a “think aloud” method. This involves recruiting a few individuals who represent our target audience, giving them realistic tasks to complete on the website or prototype (such as “Find the price of X product” or “Sign up for the newsletter”), and asking them to continuously narrate their thoughts, feelings, and expectations as they proceed. We’re not just timing them; we’re listening to their internal monologue as they attempt to achieve a goal.
The value of this method is immense. Simply watching someone click around tells you what they did, but asking them to think aloud reveals why they did it, what they were expecting, and where they became confused. It uncovers friction points we never anticipated because we’re too familiar with the design. Is the button label ambiguous? Are they looking for information in the wrong place? Does the flow make logical sense to someone seeing it for the first time? This technique provides incredibly rich, qualitative insights into user behavior and mental models, directly pinpointing where the design is failing and, importantly, why, giving us clear direction for improvement. There’s truly no substitute for obtaining these direct insights from the people we’re designing for.

Test Across Various Screen Sizes
I always test on as many screen sizes as I can find, including various tablet sizes and landscape orientation on mobile devices.
Each of these breakpoints requires careful attention to ensure your users can clearly see text, buttons, images, and more. Website design with no mistakes greatly improves trust in the business and promotes conversion.

Family and Friends Five-Second Challenge
Look… I could sit here and waffle on about heatmaps and user flow analysis like I’m auditioning for a TED Talk… but honestly? My favourite way to test a website’s usability is much simpler (and way more entertaining).
I send the site to family and friends who have absolutely no idea what the business does. No context. No brief. Then I set them a few basic tasks… find this, book that, figure out what on earth this company actually sells.
The first test is my favorite. The good old 5-second “What’s this about then?” challenge. I flash the homepage on a Zoom call for five seconds… then ask them to describe the site back to me. If they stare blankly or guess something wildly wrong… well… there’s your answer.
I did this recently with Talawa Theatre Company while testing their new site (still a work-in-progress). I got feedback from family members across different ages and tech abilities… mostly here in London, where I’m based, but also from a few further afield. The results? Brutally honest… slightly hilarious… and majorly useful.
Sometimes the best UX insight doesn’t come from analytics dashboards. It comes from your Nan asking why there’s no button that says “Buy Tickets Here.”

A/B Testing with Heatmap Analysis
One of my go-to methods for testing website usability is A/B testing combined with heatmap analysis (e.g., Hotjar), as it provides clear visual insights into user behaviors across two design variations. This approach helps identify which layout drives better engagement and guides evidence-based design improvements.

Task-Based Testing Reveals User Friction
My go-to method for testing the usability of a website design is conducting task-based user testing with real users, even in small numbers. One specific technique I use is the “five-user test,” where I give participants a set of realistic tasks—like finding a product, filling out a form, or locating contact information—and observe how easily they can complete them without guidance.
This method is valuable because it reveals usability issues that internal teams often miss. Watching someone hesitate, click in the wrong place, or express confusion tells you far more than analytics or assumptions ever could. Even with just five users, patterns emerge quickly. You start to see where friction exists in the design—unclear buttons, confusing navigation, or overlooked calls to action.
It’s not about volume; it’s about quality of insight. Task-based testing grounds the feedback in actual behavior, not just opinions. It keeps the design focused on what matters most—whether users can accomplish what they came to do, easily and confidently.

Moderated Sessions Uncover Design Flaws
My go-to method for testing the usability of a website design is conducting moderated user testing sessions via Zoom or in person. In these sessions, I give participants a list of 3-5 core tasks that reflect real use cases—such as finding a product, filling out a form, or completing a checkout. For example, if we’re testing an e-commerce site, I might ask them to locate a specific item, filter by size, add it to the cart, and complete the checkout process. I remain silent during the task but encourage participants to think aloud so I can understand their decision-making process and note where they stumble or express confusion.
This method is especially valuable because it allows us to test not just functionality, but also how intuitive the design feels from a user’s perspective. On one occasion, we assumed a sticky menu made navigation easier, but users repeatedly overlooked it because it blended too much with the background. That small insight led us to adjust the visual hierarchy, which noticeably improved engagement and time on site. It’s these raw, unscripted moments during user testing that often lead to the most impactful design changes.

Real Scenarios Expose UX Gaps
My go-to method is task-based testing using real user scenarios. Instead of asking users for general feedback, I give them specific tasks like “Find and download the brochure” or “Book a demo.” Then I observe how easily they can complete it without guidance.
I usually conduct these tests using screen recording tools combined with a quick follow-up survey to understand what confused them, what felt smooth, and where they hesitated. It helps uncover friction points that might be invisible to designers or developers who are too close to the project.
This method is valuable because it focuses on function over form. A design can look great, but if users can’t complete basic actions quickly, it fails in real-world use. Task-based testing reveals those gaps early and gives us the clarity we need to improve UX in a focused, data-driven way.

Five-Second Test Captures First Impressions
One usability testing technique I rely on is the “Five-Second Test” with follow-up questions. I show users a webpage for just five seconds, then ask what they think the page is about or what action they’d take next. It’s quick, but incredibly revealing.
This method captures first impressions – those snap judgments people make before they click anything. It helps me see if the design is clear, if the message stands out, and whether users immediately understand what the page wants them to do. Adding a few follow-up questions helps me understand why they saw things that way, which reveals gaps in clarity or visual hierarchy.
It’s a simple but powerful way to make sure a design is speaking to users right away. If a message doesn’t land in those first five seconds, there’s a good chance it’s getting lost altogether.

Real-Time Monitoring Drives Rapid Optimization
I’ve built websites for various clients, ranging from state governments to Fortune 500 companies. My preferred usability technique is real-time performance monitoring combined with rapid optimization sprints during the launch week.
Here’s my exact approach: During the Visit Arizona launch, our team simultaneously monitored live traffic patterns, bounce rates, and page load speeds across different device types. Within 24 hours, we noticed that mobile users were frequently accessing location pages but quickly bouncing off. Instead of waiting for post-launch analysis, we immediately investigated the mobile experience and discovered that media-heavy elements were significantly impacting load times.
We optimized these elements on the fly and reduced load times by 40% within the first week. This process wasn’t just about fixing problems—it revealed user behavior we hadn’t anticipated. People were using the site in ways completely different from what our pre-launch testing had suggested, especially on mobile devices.
The key is having your team ready to act on real user data immediately, not weeks later. Most agencies deliver and disappear, but the first 30 days of real traffic provide more insight into usability than any testing environment ever will.

Navigate Your Site as a User
It sounds simple, and it is – go on your website as a user. When you only navigate your website from the back end, you aren’t getting the full picture. So, open a new tab and enter your website as a user. Spend time navigating around, trying to follow normal flows of thought of how other people might be navigating around. Then, do all of this on your phone so that you can assess the usability of your website in its mobile orientation – people often don’t prioritize mobile enough!
