Top UX Trends for 2025 A Glimpse into the future

A/B testing is a method of comparing two different versions of a webpage or an advertisement by randomly showcasing them before audiences. The one with more engagement is chosen over the other.
A/B testing helps UI/UX designers gather statistical data based on user choice. UI/UX design becomes more engaging rather than designing based on the opinions of the designer.
As the testing process involves user inputs, it can provide a better user experience. 

Let’s focus on some of the top-tier A/B testing tools for UI/UX designers.

Create a UI design system for your website with our easy-to-use guide

A Complete Guide to Creating a UI Design System for Your Website in 8 Simple Steps

Projected to exceed 3.693 billion USD by 2028, the global market for UI design is fast growing. The main reason is that website design is the main impression for 94% of users. A good UI design increases conversion rates by 200%. 

Thus, having a UI design that suits your brand image, and is functional and navigable is the need of the hour for brands.

What is a UI Design System?

With a focus on aesthetics, UI focuses on creating an interface design (across devices) that users find interactive and easy-to-use. When designed and implemented well, UI improves the usability of your website and drives user engagement, making your website more productive.

Whether you want to make your website fun, interactive, or informative, the right UI design will help you achieve your website goals.

Definition of a UI Design System

Using a collection of standards, patterns, and interactive design, a UI design system aims to provide users a consistent experience across digital products and platforms. When it comes to designing a website, the UI design system standardizes the way the multiple pages have been designed. This reduces the time taken to recreate each page.

Why Do Websites Need a UI Design System?

In websites, visual consistency is a key and helps maintain uniformity. An intelligent UI design system ensures that:

  • Your website is scalable.
  • It is easy to implement changes and make updates.
  • Collaborative work is easier between the developing team and the designers.
  • You can control quality over the website.

Benefits of a UI Design System

Across all software systems, the use of UI design system has gained popularity due to the following reasons:

  • Makes a website unique and can act as a USP.
  • Make your website reflect the brand image.
  • Creates a better user experience.
  • Reduces the risk of losing knowledge when losing a team member.
  • Improves the speed and responsiveness of your website.
  • Draws more users to the website.
  • Facilitates easy navigation across web pages.
  • Makes it easier to convert customers and boost sales.

Preparing to Build Your UI Design System

Whether you want to revamp your website or deploy a new one, the best way forward is to pick a design that resonates with your brand. This carries over from the interface that you have to the tone that you use. 61.5% of designers state that clients will leave a site due to poor structure and navigation.

Thus, you need to decide whether to keep your current layout, start from scratch, or merge some existing elements with a new design. Audit your current website, and identify elements that can be useful and those that need to be scrapped. 

To add, a key component to having the UI design is identifying your target audience. A website catering to the professional sphere will be vastly different from that catering to Gen Z consumers. Pick a design that works well for your target audience. Once this is done, you are ready to get started.

8 Simple Steps to Create a UI Design System

Though UI design has a broad scope and can involve a lot, you can take a piecemeal approach with the following steps:

Step 1: Define Your Design Principles

The more haphazard the design, the higher the bounce rate* for a website. Lay out a guide that outlines every aspect from scope to design to usability. This will help create uniformity between the multiple pages. Further, this should be device compatible since 50% of users visit the mobile website of a brand instead of downloading an app.

* Bounce rate: The percentage of unengaged sessions. The user stays on the website for less than 10 seconds, does not view any other page in the website, and there are no key events. 

Step 2: Create a Visual Style Guide

Pick a typography that makes your content stand out and easy to read. Further, using the brand colors on the website creates a link between the brand and the website. To add, the content (images, texts, links, etc.) should be spaced properly to create an appealing style.

The best way to do this is to create a visual guide before the developers start working on the website’s design.

Step 3: Build a Component Library

Take all the functional/decorative items such as input fields, menus, buttons, and images. Sort through them to identify what is usable and what is not.

Once you have what is useful, create a repository from which you can pick components as required.

Step 4: Document Interaction Patterns

Test how interactive your design is. This includes the hover effects, button animations, sliding images, pop ups, menus, drop downs, etc. Check their functionality and response time. Faster websites have 11% higher conversion rates and increased engagement by 20%.

Step 5: Set Up Accessibility Standards

To increase the target audience base and ensure that people have an easier time navigating your website, it needs to meet the accessibility standards. This ensures that people, whether differently abled or otherwise, can use the website. This means being perceivable, operable, understandable, and robust. 

Make sure that the website sticks to the WCAG 2.0 guidelines and can be scaled up as and when required. 

Step 6: Choose the Right Tools

Figma, Sketch, Adobe XD, and InVision are some of the top tools that can help test your website at the design and prototype stage. Pick the tool that suits you best to run all the checks before roll-out. 

Step 7: Test Your Design System

A firm belief of 83% of users is that websites should provide a seamless experience no matter the device. No matter the target audience, websites need to be usable, consistent across the pages, and accessible via different devices. During the testing stage, you need to keep this in mind. 


Some of the most important checks for a website before roll-out are usability, readability, layout consistency, performance, security, and device compatibility. Check all aspects of the website, from response time to formatting before the website is deployed.

Step 8: Maintain and Update Regularly

Website development is not a one-and-done job. Create a route via which the website can be updated regularly to keep up with the security protocols that are deployed as well as other changes that are implemented across the internet. Further, this ensures that the website remains compatible with the different browser versions.

The 7 Key Qualities That Make a UI Design Successful

The global market for UI design stood at 2.43 billion USD in 2024, estimated to rise to 7.43 billion USD by 2032, a predicted CAGR of 15.01%. For 94% of users, the impression a website makes on them is design-related.

Thus, to make a website successful, the UI Design implemented needs to match up to the standards of the audience.

A Brief Intro to UI Design

User experience can make or break a website. If your website is designed well, visitors will use it without complaint. However, as important aesthetics are, functionality is what truly interests users.

Herein comes UI Design. A whole process designed to make a software both useful and visually appealing, applying UI Design principles to your website gives it an edge over others.

During its lifetime, UI design goes through the following cycle:

  • Analysis of the existing website.
  • Conception and design.
  • Development and testing.
  • Evaluation of the website with the help of user feedback.
  • Iterative action to fine-tune the website.

The Whys and Hows of UI Design

For 94% of users, navigation is one of the biggest factors influencing them to use a website. Further, as per Forbes, effective UI design can lead to a 200% boost in client conversion. 

Applying UI Design principles to a website results in the following:

  • Makes the website efficient and user-friendly.
  • Guides users toward particular pages.
  • Decreases the cognitive load on the users.
  • Creates the brand perception that you want.

When creating a UI Design for any website, it is important to keep the following in mind:

  • Know your audience.
  • Remove what is unnecessary.
  • Make website navigation easy.
  • Carefully plan the content you want to upload.
  • Test the website properly to remove glitches and bugs before making it live.
  • Update as and when required.

7 Traits that Make a UI Design Fruitful

While the basics are known to all designers, certain design aspects can make your website stand out among the others. Though UI Design is implemented by all websites to some extent, having the below makes applying UI Design worth the effort:

 

1. Make the Website’s Design Intuitive and Responsive

Some of us are just more technologically challenged than others and this is true when it comes to the users of any website. However, websites are designed for all and not just a select few. Having an intuitive design ensures that the visitors to your website do not feel lost and are able to seek out the web page they need.

Further, many access websites through mobiles while others use a computer. 39% leave a website if the images take too long to load. The UI design needs to be compatible and responsive irrespective of devices. This helps users navigate the site easily and in turn makes the website rank higher on search indexes.

2. Introduce Familiarity to the Interface

Being intuitive is not all that a website needs to be. If people are completely unfamiliar with the icons, indexes, and even the layout of a website, an intuitive website will not result in much. If users are unable to find the right webpage or product, they will leave the site, increasing your bounce rate.

Having an element of familiarity in the design makes the website easy to understand and navigate. In turn, this reduces cognitive strain on the users.

3. Maintain a Clear and Consistent Outline and Content

A uniform design makes the user’s experience on any website pleasant. The interface needs to have a clear and consistent design across pages, making it easy to navigate. Further, it makes the multiple design aspects work together like a single unit. 38% stop interacting with a website if the content is not appealing. It also makes the different pages predictable to users once they are familiar with the website, giving a boost to user comfort.

To add, clarity in the design makes the website well organized. Using a legible font and the same font across pages, icons that can be easily identified and located, and a design that does not overwhelm the users will result in a more concise and functional website. Implement this to save time, increase engagement, boost credibility, and enhance your brand image.

4. Less can be More if Done Right

Too many pictures, pop-ups, or text, can overwhelm a person when they look at a website. When a website is overcrowded with CTAs or text, it comes across as too commercial and pushy, immediately losing visitors.

Opting for a minimalist UI Design will help clean up your website of unnecessary content and thus reduce clutter. This will also result in a streamlined website that has clear CTAs and redirect links to relevant pages.

If you look at the top brands, you will find that the homepage has only a few lines of relevant text and images along with a well-organized CTA. This reflects a minimalist outlook resulting in a clean, sleek design.

5. Guide Users with Visual Hierarchy

When designing a website, you can choose to push a certain product or service. However, this is best done with subtlety, guiding them toward the product as they navigate the website.

Here, visual hierarchy comes into play and the UI design can be used effectively. Some aspects of this include making some elements larger than others to draw attention (such as CTAs), using bright colors as well as muted tones, and adjusting the spacing and layout.

86% would rather look at the product pages than the homepage. Guide your users across the page by putting the more important elements on top and making them stand out. Try clean lines and defined elements to make your website look appealing and organized.

6. Make the UI Design Accessible and Inclusive

Websites, though they are targeted towards a certain part of the population, need to be inclusive of all. This includes people who have different levels of technological ability and those who are differently abled. Not everyone can be expected to navigate the website with the same amount of ease.

Impacting 8-10% of the adult male population, color blindness can be a hindrance when accessing a website. Furthermore, 253 million people suffer from some level of blindness.

Contrast between headers, tabs, and icons, using alt image text, interactive links, and keyboard tabs (for handheld devices), can be a good option to make your website more accessible. Use a font as well as a color scheme that is visible, interpretable, and appealing. You can also try using prompts beside the entry fields to make them easier for people.

Following the Web Content Accessibility Guidelines help ensure that the website you design is accessible to a broad group of people.

7. Be Ready for an Iterative Process

UI Design is not a one-and-done activity. While you need to test the website extensively before making it live, user feedback also needs to be collected once it is live. This helps developers and designers reevaluate the design implemented.

Making small tweaks such as a few changes to the checkout page or the service pages, or a few changes in the layout of the menu tabs can make a big difference. This can be done over time from the various inputs that you get from the users.

Some Pro Tips for UI Design

To make a website that is perfect for your target audience, you can try the below:

  • View the website from the perspective of the users.
  • Make using the website so effortless that the UI does not seem like a separate entity.
  • Streamline the workflow when you get started on the design.
  • Test the site repeatedly before deploying.

Though it seems repetitive, these are tried and tested methods adopted by the experts for the best results.

Improving UI Design for a better user experience

While a number of factors work in tandem to ensure that a website is aesthetically pleasing and easy to navigate, UI Design is a core aspect. A successful UI design is targeted towards the audience, intuitive, accessible, and concise.

For a seamless experience that ensures visitor retention, use UI Design to create a user-centric website.
