How to Measure Success of Your UI/UX Design Efforts

A UI/UX design part of the project is no small feat — it takes time, effort, and skills. And the job doesn’t end with creating a design concept itself; you need to measure its impact and success.

Without clear metrics, promoting your product and understanding what to improve can be difficult. Is my UX good? How will users perceive my UI? What shall I improve? To answer these questions, a set of valuable UI/UX metrics comes in handy.

Speaking of numbers, 94% of users mistrust a website because of its design. This highlights the importance of a well-designed and tested UI and UX to create a positive brand that users trust. 

Now, without further ado, let’s talk about how to measure success in UI/UX design.

The Importance of UI/UX

UI (user interface) and UX (user experience) design are the Tony Stark of software development — it powers everything. Not only is it responsible for the visual component of a digital product, but it affects users’ satisfaction, playing a crucial role in the success of your business. 

A well-planned UI/UX will help your website or app stand out, improve conversions, and drive customer loyalty while increasing brand awareness. It’s the key to your software success. But how to measure it?

How to Measure Success in UI/UX Design

User interface metrics and user experience metrics are the key indicators of a website or an app’s performance. 

To measure them, businesses can use various tools and techniques, such as user feedback, surveys, A/B testing, or analytics tools like Google Analytics, User Zoom, Qualtrics, or Hotjar. 

By constantly tracking and measuring ROI, KPIs, and other UI and UX metrics, you can gain insights into how users behave and respond to your software. From there, you can identify areas for improvement, optimizing your design for maximum impact.

Let’s overview the most important UI/UX design metrics you should pay attention to.

Essential UI metrics to evaluate your product’s appearance

To evaluate your UI design efforts, you can use a variety of metrics and KPIs that focus on different aspects of the visual design and aesthetics of your product.  Particularly:

  1. Visual appeal

The visual appeal of software is quite subjective; however, it can still help you understand the attractiveness of your UI design through surveys or user feedback.

  1. Consistency

Another one of the most critical UI KPIs is design consistency. All your fonts, colors, layouts, and other elements should be consistent throughout the project to ensure the brand identity is sustained.

  1. Clarity

Ensure that your product’s user interface clearly and effectively communicates the information without misleading or confusing users and that they can easily understand how to interact with the website or application. This can be tracked via surveys, usability testing, or user feedback. 

  1. Bounce rate

The bounce rate measures the percentage of users who leave your website or app without taking any action or interacting with any additional pages. A high bounce rate can help evaluate UI design and indicate whether it is too complex or not engaging enough.

Essential UX metrics to evaluate your product’s usability

User experience measurement is the number-one step to improving the effectiveness of your software. To evaluate your UX design efforts, consider tracking the following metrics:

  1. Responsiveness

Responsiveness refers to the speed and fluidity with which your app or website responds to user interactions and input. Regardless of the device, your software should be adapted to every user.

  1. User flow

The user flow is a visualization of how users navigate your website or app — for example, the actions they perform or how they move from one page to another. This can help you to identify areas of your UX design that may be causing confusion and make improvements to optimize user navigation.

  1. Task success rate

The task success rate helps measure UX in task completion, such as completing a registration form, signing up, or adding an item to a shopping cart. It is shown as the percentage of users who successfully completed a task without errors or customer support. This metric is calculated as the number of correctly completed tasks to the total number of attempts.

  1. Time on task

Time on task is another vital UX KPIs metric that refers to the time it takes for users to complete a task successfully. As a rule of thumb, the shorter the duration, the better the UX. This metric is calculated as the average time taken to complete one task to the total time to complete all tasks.

  1. Search vs. navigation

In case a user cannot find the necessary element via organic navigation, a search function is the next logical step to undertake. For UX, the less the search bar is used, the better. This metric is usually calculated as the number of completed tasks via navigation or search to the total number of completed tasks.

  1. User error rate

The user error rate KPI identifies the number of errors a user makes while completing a task, such as clicking on something that isn’t clickable, opening the wrong page, etc. This metric shows how user-friendly your website is for the average person and helps you to ensure the software you’ve created isn’t confused or misleading.

It can be calculated as either the number of errors to the total number of task attempts or the total number of errors for all users to the total number of error opportunities for all users.

  1. System usability scale

The system usability scale, or SUS, can help measure the usability of products or services. It is a test that allows participants to rate the software’s usability and learnability. The SUS is scored from 0–100, with 68 considered an above-average score.

  1. Net promoter score 

The net promoter score, or NPS, is a metric that identifies the likelihood that customers will recommend the software product to others. 

It can be calculated by asking users: “How likely are you to recommend this software to a friend or colleague on a scale of 0 to 10?” Based on ratings, the users are classified as promoters (ranks 9 or 10), passives (ranks 7 or 8), or detractors (ranks 6 or lower). Subtracting the percentage of detractors from the percentage of promoters yields the NPS.

  1. Customer satisfaction score

The customer satisfaction score, or CSAT, is one of the most important UX KPIs. It measures user satisfaction by asking them, “How satisfied are you with the software on a scale of 1 to 5?” 

Checking a CSAT regularly helps you to track user satisfaction and learn how to change or improve your product, feature, or website.

  1. Conversion rate

The conversion rate (the number of users who performed the action to the number of those who have the opportunity) can also be used to evaluate UX and ROI. If the number of conversions grew after some visual changes, then you can be sure that this has made an impact on your revenue.

  1. Drop-off rate

The drop-off rate, or customer churn rate, shows how many people left the conversion funnel without performing a specific action. It can be calculated by tracking bounces over pages and identifying the funnel steps that caused this drop-off. Measuring the UX drop-off rate can help you understand your customer pain points.

  1. Retention rate

The retention rate analyzes the percentage of loyal customers and helps businesses to understand their position in the market compared to the competitors. It can be calculated by dividing your active users at the end of a certain period by the total number of active users you had at the beginning of that time. 

The average retention rate should be in the 92-97% range. If you get a lower result, consider identifying some loopholes in your user experience design.
