5 tips for running an effective usability test

Are your users engaged in your website? The success of your website will largely depend on your answer. After all, engaged users are valuable users; they keep coming back and will recommend your site to colleagues, friends, and family. So, if you’re not sure if your users are engaged or not, consider looking into your user engagement metrics.

‍

User engagement can be measured using a number of key metrics provided by website analytics platforms. Metrics such as bounce rate, time on page, and click-through rate all provide clues to user engagement and therefore overall website user experience.

‍

This article will help you understand user engagement and why it’s important to measure. We’ll also discuss how to apply user engagement insights to improve website success. Combining a little bit of data with some user research is a powerful thing, so let’s get into it.

‍

‍

‍

Understanding User Engagement Metrics 📐

‍

User engagement metrics provide valuable insight for both new and existing websites. They should be checked regularly as a sort of ‘pulse check’ for website user experience and performance. So, what metrics should you be looking at? Website metrics can be overwhelming; there are hundreds if not thousands to analyze, so let’s focus on three:

‍

‍

Bounce rate

‍
Measures the percentage of users that visit just one page on your site before leaving. If your bounce rate is high it suggests that users aren’t finding the content relevant, engaging, or useful. It points to a poor initial reaction to your site and means that users are arriving, making a judgment about your design or content, and then leaving.

‍

‍

Time on page

‍
Calculated by the time difference between the point when a person lands on the page and when they move on to the next one. It indicates how engaging or relevant individual pages on your website are. Low time on page figures suggest that users aren’t getting what they need from a certain page, either in terms of the content, the aesthetics, or both.

‍

‍

Click-through rate

‍
Click-through rate compares the number of times someone clicks on your content, to the number of impressions you get (how many times an internal link or ad was viewed). The higher the rate, the better the engagement and performance of that element. User experience design can influence click-through rates through copywriting, button contrasts, heading structure, navigation, etc.

‍

‍

Conversion rate

‍
Conversion rates are perhaps the pinnacle of user engagement metrics. Conversion rate is the percentage of users that perform specific tasks you define. They are therefore dictated by your goals, which could include form submissions, transactions, etc. If your website has high conversion rates, you can be fairly confident that your website is matching your users’ needs, requirements, and expectations.

‍

But how do these metrics help? Well, they don’t give you an answer directly. The metrics point to potential issues with website user experience. They guide further research and subsequent updates that lead to website improvement. In the next section, we’ll discuss how these and others can support better website user experiences.

‍

‍

‍

Identifying Areas for Improvement 💡

‍

So, you’ve looked at your website’s user engagement metrics and discovered some good, and some bad. The good news is, there’s value in discovering both! The catch? You just need to find it. Remember, the metrics on their own don’t give you answers; they provide you direction.

‍

The ‘clues’ that user engagement metrics provide are the starting point for further research. Remember, we want to make data-driven decisions. We want to avoid making assumptions and jumping to conclusions about why our website is reporting certain metrics. Fortunately, there are a bunch of different ways to do this.

‍

User research data can be gathered by using both qualitative and quantitative research techniques. Insights into user behavior and needs can reveal why your website might be performing in certain ways. Research can include both qualitative and quantitative techniques.

‍

‍

Qualitative research techniques

‍

• Usability test – Test a product with people by observing them as they attempt to complete various tasks.
• User interview – Sit down with a user to learn more about their background, motivations and pain points.
• Contextual inquiry – Learn more about your users in their own environment by asking them questions before moving onto an observation activity.
• Focus group – Gather 6 to 10 people for a forum-like session to get feedback on a product.

‍

‍

Quantitate research techniques

‍

• Card sorts – Find out how people categorize and sort information on your website.
• First-click tests – See where people click first when tasked with completing an action.
• A/B tests – Compare 2 versions of a design in order to work out which is more effective.
• Clickstream analysis – Analyze aggregate data about website visits.
• Tree-testing - Test your site structure using text-only categorization and labels

‍

The type of research depends on what question you want to answer. Being specific about your question will help you identify what research technique(s) to deploy and ultimately the quality of your answer. If you’re serious about website improvement; identify problem areas with user engagement metrics, and investigate how to fix them with user research.

‍

‍

‍

Optimizing Content and Design

‍

If you have conducted user research and found weak areas on your website, there are many things to consider. Three good places to start are navigation, content, and website layout. Combined, these have a huge impact on user experience and can be leveraged to address disappointing engagement metrics.

‍

‍

Navigation

‍
Navigation is a crucial aspect of creating a good user experience since it fundamentally connects pages and content which allows users to find what they need. Navigation should be simple and easy to follow, with important information/actions at the top of menus. Observing the results of card sorting, tree testing, and user testing can be particularly useful in website optimization efforts. You may find that search bars, breadcrumb trails, and internal links can also help overcome navigation issues.

‍

‍

Content

‍
Are users seeing compelling or relevant content when they arrive on your site? Is your content organized in a way that encourages further exploration? Card sorting and content audits are useful in answering these questions and can help provide you with the insights required to optimize your content. You should identify what content might be redundant, out of date, or repetitive, as well as any gaps that may need filling.

‍

‍

Layout

‍
A well-designed layout can improve the overall usability of a website, making it easier for users to find what they're looking for, understand the content, and engage with it. Consider how consistent your heading structures are and be sure to use consistent styling throughout the site, such as similar font sizes and colors. Don’t be afraid to use white space; it’s great at breaking up sections and making content more readable.

‍

An additional factor related to layout is mobile optimization. Mobile-first design is necessary for apps, but it should also factor into your website design. How responsive is your website? How easy is it to navigate on mobile? Is your font size appropriate? You might find that poor mobile experience is negatively impacting user engagement metrics.

‍

‍

‍

Measuring Success 🔎

‍

User experience design is an iterative, ongoing process, so it’s important to keep a record of your website’s user experience metrics at various points of development. Fortunately, website analytics platforms will provide you with historic user data and key metrics; but be sure to keep a separate record of what improvements you make along the way. This will help you pinpoint what changes impacted different metrics.

‍

Define your goals and create a website optimization checklist that monitors key metrics on your site. For example, whenever you make an update, ensure bounce rates don’t exceed a certain number during the days following; check that your conversion rates are performing as they should be; check your time on sites hasn’t dropped. Be sure to compare metrics between desktop and mobile too.

‍

User’s needs and expectations change over time, so keep an eye on how new content is performing. For example, which new blog posts have attracted the most attention? What pages or topics have had the most page views compared to the previous period? Tracking such changes can help to inform what your users are currently engaged in, and will help guide your user experience improvements.

‍

‍

‍

Conclusion 🤗

‍

User engagement metrics allow you to put clear parameters around user experience. They allow you to measure where your website is performing well, and where your website might need improving. Their main strength is in how accessible they are; you can access key metrics on website analytics platforms in moments. However, user engagement metrics on their own may not reveal how and why certain website improvements should be made. In order to understand what’s going on, you often need to dig a little deeper.

‍

Time on page, bounce rate, click-through rate, and conversion rates are all great starting points to understand your next steps toward website improvement. Use them to define where further research may be needed. Not sure why your average pages per session is two? Try conducting first-click testing; where are they heading that seems to be a dead end? Is your bounce rate too high? Conduct a content audit to find out if your information is still relevant, or look into navigation roadblocks. Whatever the question; keep searching for the answer.

‍

User engagement metrics will keep you on your toes, but that’s a good thing. They empower you to make ongoing website improvements and ensure that users are at the heart of your website design. 

When it comes to financial services, user experience goes way beyond just making things easy to use. It’s about creating a seamless journey and establishing trust at every touchpoint. Think about it: as we rely more and more on digital banking and financial apps in our everyday lives, we need to feel absolutely confident that our personal information is safe and that the companies managing our money actually know what they're doing. Without that trust foundation, even the most competitive brands will struggle with customer adoption.

‍

Why Trust Matters More Than Ever

‍

The stakes are uniquely high in financial UX. Unlike other digital products where a poor experience might result in minor frustration, financial applications handle our life savings, investment portfolios, and sensitive personal data. A single misstep in design can trigger alarm bells for users, potentially leading to lost customers.

‍

Using UX Research to Measure and Build Trust

‍

Building high trust experiences requires deep insights into user perceptions, behaviors, and pain points. The best UX platforms can help financial companies spot trust issues and test whether their solutions actually work.

‍

Identify Trust Issues with Tree Testing

‍

Tree testing helps financial institutions understand how easily users can find critical information and features:

‍

• Test information architecture to ensure security features and privacy information are easily discoverable
• Identify confusing terminology that may undermine user confidence
• Compare findability metrics for trust-related content across different user segments

‍

Optimize for Trustworthy First Impressions with First-Click Testing

‍

First-click testing helps identify where users naturally look for visual symbols and cues that are associated with security:

‍

• Test where users instinctively look for security indicators like references to security certifications
• Compare the effectiveness of different visual trust symbols (locks, shields, badges)
• Identify the optimal placement for security messaging across key screens

‍

Map User Journeys with Card Sorting

‍

Card sorting helps brands understand how users organize concepts. Reducing confusion, helps your financial brand appear more trustworthy, quickly:

‍

• Use open card sorts to understand how users naturally categorize security and privacy features
• Identify terminology that resonates with users' perceptions around security

‍

Qualitative Insights Through Targeted Questions

‍

Gathering qualitative data through strategically placed questions allows financial institutions to collect rich, timely insights about how much their customers trust their brand:

‍

• Ask open ended questions about trust concerns at key moments in the testing process
• Gather specific feedback on security terminology understanding and recognition
• Capture emotional responses to different trust indicators

‍

What Makes a Financial Brand Look Trustworthy?

‍

Visual Consistency and Professional Polish

‍

When someone opens your financial app or website, they're making snap judgments about whether they can trust you with their money. It happens in milliseconds, and a lot of that decision comes down to how polished and consistent everything looks.Clean, consistent design sends that signal of stability and attention to detail that people expect when money's involved.

‍

To achieve this, develop and rigorously apply a solid design system across all digital touchpoints including fonts, colors, button styles, and spacing, it all needs to be consistent across every page and interaction. Even small inconsistencies can make people subconsciously lose confidence.

‍

Making Security Visible

‍

Unlike walking into a bank where you can see the vault and security cameras, digital security happens behind the scenes. Users can't see all the protection you've built in unless you make a point of showing them.

‍

Highlighting your security measures in ways that feel reassuring rather than overwhelming gives people that same sense of "my money is safe here" that they'd get from seeing a bank's physical security.

‍

From a design perspective, apply this thinking to elements like:

‍

• Real time login notifications
• Transaction verification steps
• Clear encryption indicators
• Transparent data usage explanations
• Session timeout warnings

‍

You can test the success of these design elements through preference testing, where you can compare different approaches to security visualization to determine which elements most effectively communicate trust without creating anxiety.

‍

Making Complex Language Simple

‍

Financial terminology is naturally complex, but your interface content doesn't have to be. Clear, straightforward language builds trust so it’s important to develop a content strategy that:

‍

• Explains unavoidable complex terms contextually
• Replaces jargon with plain language
• Provides proactive guidance before errors occur
• Uses positive, confident messaging around security features

‍

You can test your language and navigation elements by using tree testing to evaluate user understanding of different terminology, measuring success rates for finding information using different labeling options.

‍

Create an Ongoing Trust Measurement Program

‍

A user research platform enables financial institutions to implement ongoing trust measurement across the product lifecycle:

‍

Establish Trust Benchmarks

‍

Use UX research tools to establish baseline metrics for measuring user trust:

‍

• Findability scores for security features
• User reported confidence ratings
• Success rates for security related tasks
• Terminology comprehension levels

‍

Validate Design Updates

‍

Before implementing changes to critical elements, use quick tests to validate designs:

‍

• Compare current vs. proposed designs with prototype testing
• Measure findability improvements with tree testing
• Evaluate usability through first-click testing

‍

Monitor Trust Metrics Over Time

‍

Create a dashboard of trust metrics that can be tracked regularly:

‍

• Task success rates for security related activities
• Time-to-completion for verification processes
• Confidence ratings at key security touchpoints

‍

Cross-Functional Collaboration to Improve Trust

‍

While UX designers can significantly impact brand credibility, remember that trust is earned across the entire customer experience:

‍

• Product teams ensure feature promises align with actual capabilities
• Security teams translate complex security measures into user-friendly experiences
• Marketing ensures brand promises align with the actual user experience
• ‍Customer service supports customers when trust issues arise

‍

Trust as a Competitive Advantage

‍

In an industry where products and services can often seem interchangeable to consumers, trust becomes a powerful differentiator. By placing trust at the center of your design philosophy and using comprehensive user research to measure and improve trust metrics, you're not just improving user experience, you're creating a foundation for lasting customer relationships in an industry where loyalty is increasingly rare.

‍

The most successful financial institutions of the future won't necessarily be those with the most features or the slickest interfaces, but those that have earned and maintained user trust through thoughtful UX design built on a foundation of deep user research and continuous improvement.

‍

‍

Usability experts play an essential role in the user interface design process by evaluating the usability of digital products from a very important perspective - the users! Usability experts utilize various techniques such as heuristic evaluation, usability testing, and user research to gather data on how users interact with digital products and services. This data helps to identify design flaws and areas for improvement, leading to the development of user-friendly and efficient products.

‍

Heuristic evaluation is a usability research technique used to evaluate the user interface design of a digital product based on a set of ‘heuristics’ or ‘usability principles’. These heuristics are derived from a set of established principles of user experience design - attributed to the landmark article “Improving a Human-Computer Dialogue” published by web usability pioneers Jakob Nielsen and Rolf Molich in 1990. The principles focus on the experiential aspects of a user interface. 

‍

In this article, we’ll discuss what heuristic evaluation is and how usability experts use the principles to create exceptional design. We’ll also discuss how usability testing works hand-in-hand with heuristic evaluation, and how minimalist design and user control impact user experience. So, let’s dive in!

‍

‍

Understanding Heuristic Evaluation

Heuristic evaluation helps usability experts to examine interface design against tried and tested rules of thumb. To conduct a heuristic evaluation, usability experts typically work through the interface of the digital product and identify any issues or areas for improvement based on these broad rules of thumb, of which there are ten. They broadly cover the key areas of design that impact user experience - not bad for an article published over 30 years ago!

‍

The ten principles are:

‍

1. Prevention error: Well-functioning error messages are good, but instead of messages, can these problems be removed in the first place? Remove the opportunity for slips and mistakes to occur.
2. Consistency and standards: Language, terms, and actions used should be consistent to not cause any confusion.
3. Control and freedom for users: Give your users the freedom and control to undo/redo actions and exit out of situations if needed.
4. System status visibility: Let your users know what’s going on with the site. Is the page they’re on currently loading, or has it finished loading?
5. Design and aesthetics: Cut out unnecessary information and clutter to enhance visibility. Keep things in a minimalist style.
6. Help and documentation: Ensure that information is easy to find for users, isn’t too large and is focused on your users’ tasks.
7. Recognition, not recall: Make sure that your users don’t have to rely on their memories. Instead, make options, actions and objects visible. Provide instructions for use too.
8. Provide a match between the system and the real world: Does the system speak the same language and use the same terms as your users? If you use a lot of jargon, make sure that all users can understand by providing an explanation or using other terms that are familiar to them. Also ensure that all your information appears in a logical and natural order.
9. Flexibility: Is your interface easy to use and it is flexible for users? Ensure your system can cater to users to all types, from experts to novices.
10. Help users to recognize, diagnose and recover from errors: Your users should not feel frustrated by any error messages they see. Instead, express errors in plain, jargon-free language they can understand. Make sure the problem is clearly stated and offer a solution for how to fix it.

‍

Heuristic evaluation is a cost-effective way to identify usability issues early in the design process (although they can be performed at any stage) leading to faster and more efficient design iterations. It also provides a structured approach to evaluating user interfaces, making it easier to identify usability issues. By providing valuable feedback on overall usability, heuristic evaluation helps to improve user satisfaction and retention.

‍

‍

‍

The Role of Usability Experts in Heuristic Evaluation

‍

‍

Usability experts play a central role in the heuristic evaluation process by providing feedback on the usability of a digital product, identifying any issues or areas for improvement, and suggesting changes to optimize user experience.

‍

One of the primary goals of usability experts during the heuristic evaluation process is to identify and prevent errors in user interface design. They achieve this by applying the principles of error prevention, such as providing clear instructions and warnings, minimizing the cognitive load on users, and reducing the chances of making errors in the first place. For example, they may suggest adding confirmation dialogs for critical actions, ensuring that error messages are clear and concise, and making the navigation intuitive and straightforward.

‍

Usability experts also use user testing to inform their heuristic evaluation. User testing involves gathering data from users interacting with the product or service and observing their behavior and feedback. This data helps to validate the design decisions made during the heuristic evaluation and identify additional usability issues that may have been missed. For example, usability experts may conduct A/B testing to compare the effectiveness of different design variations, gather feedback from user surveys, and conduct user interviews to gain insights into users' needs and preferences.

‍

Conducting user testing with users that represent, as closely as possible, actual end users, ensures that the product is optimized for its target audience. Check out our tool Reframer, which helps usability experts collaborate and record research observations in one central database.

‍

‍

‍

Minimalist Design and User Control in Heuristic Evaluation

‍

‍

Minimalist design and user control are two key principles that usability experts focus on during the heuristic evaluation process. A minimalist design is one that is clean, simple, and focuses on the essentials, while user control refers to the extent to which users can control their interactions with the product or service.

‍

Minimalist design is important because it allows users to focus on the content and tasks at hand without being distracted by unnecessary elements or clutter. Usability experts evaluate the level of minimalist design in a user interface by assessing the visual hierarchy, the use of white space, the clarity of the content, and the consistency of the design elements. Information architecture (the system and structure you use to organize and label content) has a massive impact here, along with the content itself being concise and meaningful.

‍

Incorporating minimalist design principles into heuristic evaluation can improve the overall user experience by simplifying the design, reducing cognitive load, and making it easier for users to find what they need. Usability experts may incorporate minimalist design by simplifying the navigation and site structure, reducing the number of design elements, and removing any unnecessary content (check out our tool Treejack to conduct site structure, navigation, and categorization research). Consistent color schemes and typography can also help to create a cohesive and unified design.

‍

User control is also critical in a user interface design because it gives users the power to decide how they interact with the product or service. Usability experts evaluate the level of user control by looking at the design of the navigation, the placement of buttons and prompts, the feedback given to users, and the ability to undo actions. Again, usability testing plays an important role in heuristic evaluation by allowing researchers to see how users respond to the level of control provided, and gather feedback on any potential hiccups or roadblocks.

‍

‍

‍

Usability Testing and Heuristic Evaluation

‍

‍

Usability testing and heuristic evaluation are both important components of the user-centered design process, and they complement each other in different ways.

‍

Usability testing involves gathering feedback from users as they interact with a digital product. This feedback can provide valuable insights into how users perceive and use the user interface design, identify any usability issues, and help validate design decisions. Usability testing can be conducted in different forms, such as moderated or unmoderated, remote or in-person, and task-based or exploratory. Check out our usability testing 101 article to learn more.

‍

On the other hand, heuristic evaluation is a method in which usability experts evaluate a product against a set of usability principles. While heuristic evaluation is a useful method to quickly identify usability issues and areas for improvement, it does not involve direct feedback from users.

‍

Usability testing can be used to validate heuristic evaluation findings by providing evidence of how users interact with the product or service. For example, if a usability expert identifies a potential usability issue related to the navigation of a website during heuristic evaluation, usability testing can be used to see if users actually have difficulty finding what they need on the website. In this way, usability testing provides a reality check to the heuristic evaluation and helps ensure that the findings are grounded in actual user behavior.

‍

Usability testing and heuristic evaluation work together in the design process by informing and validating each other. For example, a designer may conduct heuristic evaluation to identify potential usability issues and then use the insights gained to design a new iteration of the product or service. The designer can then use usability testing to validate that the new design has successfully addressed the identified usability issues and improved the user experience. This iterative process of designing, testing, and refining based on feedback from both heuristic evaluation and usability testing leads to a user-centered design that is more likely to meet user needs and expectations.

‍

‍

‍

Conclusion

‍

‍

Heuristic evaluation is a powerful usability research technique that usability experts use to evaluate digital product interfaces based on a set of established principles of user experience design. After all these years, the ten principles of heuristic evaluation still cover the key areas of design that impact user experience, making it easier to identify usability issues early in the design process, leading to faster and more efficient design iterations. Usability experts play a critical role in the heuristic evaluation process by identifying design flaws and areas for improvement, using user testing to validate design decisions, and ensuring that the product is optimized for its intended users.

‍

Minimalist design and user control are two key principles that usability experts focus on during the heuristic evaluation process. A minimalist design is clean, simple, and focuses on the essentials, while user control gives users the freedom and control to undo/redo actions and exit out of situations if needed. By following these principles, usability experts can create an exceptional design that enhances visibility, reduces cognitive load, and provides a positive user experience. 

‍

Ultimately, heuristic evaluation is a cost-effective way to identify usability issues at any point in the design process, leading to faster and more efficient design iterations, and improving user satisfaction and retention. How many of the ten heuristic design principles does your digital product satisfy?
