3. Forgetting to label your icons

Many apps use the same icons. Icons like stars, hearts and check marks. These icons can mean different things in different apps. Use labels to help users know what the icon means.

4. Misleading users with links and buttons

Make sure that buttons and links do what you promised. It should take the user somewhere or do something. A general rule is that a link needs to go somewhere. Buttons allow a user to do something. Don’t use links to add, change or delete any data on the screen.

When do you use a button? First, consider what task you want the user to do. If they need to Buy, Sign Up or Add something, use a button. You may use secondary buttons for different tasks. Your primary action should stand out. For other actions like going to a new page, you can use a link.

5. Slow load times

Slow loading pages can annoy your users. Use tools like PageSpeed Insights to tell you what is slowing your site down. Images, fonts and videos can slow your site down.

6. No way to distinguish a primary and secondary button

Sometimes you’ll have more than one action that you want the user to do. It’s important to make it easy for them to identify the primary action. Your primary button should be bolder and more prominent. Choose a strong color with bold text to help it stand out.

7. No text hierarchy

People scan your UI to figure out what to do. Text hierarchy helps them to know what to pay attention to. Use size, color and weight to show importance of text. Include spacing to separate different pieces of information.

Design mistakes can happen. You can create a better user experience by avoiding these common UX mistakes.
