Good user interface design can greatly enhance your website, allowing it to make a good first impression while encouraging users to take action.
However, design isn't everything. You should remember who you're designing for by using a customer journey builder to ensure you understand how users will interact with your app, website, or another digital product. Then, you can use UX/UI design principles to cater to the needs and preferences of your target audience.
Using Fitts' law means considering that the larger an object is and the closer it is to the user's starting point, the easier it is to reach. Keeping this in mind when designing e-commerce websites, web designers can focus on the interactive elements that drive conversions.
Increased user engagement
Good user interfaces can encourage user engagement. When a site is intuitive and pleasing to use, users are more likely to spend time using it and explore its full range of capabilities.
Increased sales and conversions
Good UX/UI design can increase conversion rates and boost sales, especially because it focuses on interactive elements like links and buttons. By streamlining the path to purchase and making the process intuitive, more users are likely to complete their purchases, contributing to increased revenue.
Improved brand perception
Your website is often the first impression customers have of your business. The quality of your web design can reflect on your brand as a whole. High-quality design enhances user perception of your business, making it seem more professional and trustworthy.
Investing in good UX/UI design can save businesses money in the long run by reducing the need for extensive revisions, testing, and redesigns down the line. A good user experience on a website, app, or product can also decrease customer support costs by minimizing confusion and error.
Quality UX design also includes designing for accessibility, ensuring that people with varying abilities can use your products. This not only widens your potential user base but also promotes inclusivity.
Other key UX/UI design principles
While Fitts' law is a crucial UX/UI design principle, it's not the only one businesses should consider if they want to have a high-converting website. Other design principles include:
Hick's law states that the more choices and complexity of those choices, the longer it takes for a user to make a decision. This is one reason why landing pages designed for sales have a single call-to-action (CTA). By limiting the number of choices to one, you can drastically shorten the time it takes for a user to take action.
Miller's law is based on cognitive psychology and states that the average number of objects a person can remember is seven. For web designers, this implies that lists, menus, and other options should be limited to around seven items or less. Too many options can be overwhelming for users, making it challenging to navigate the interface and retain information.
Law of proximity
The law of proximity states that objects near each other are perceived as related. The closer an object is to another, the more closely related they appear to users, which can help web designers organize information on all their web pages while guiding the user's eye.
