Cramming Too Much on One Screen

When too much content is squeezed onto one page, users lose focus and leave quickly. A cluttered layout makes it hard to identify the main purpose of the page.

What to do:

• Keep one clear objective per screen
• Use enough white space to create balance
• Maintain visual hierarchy for easy scanning

A clean layout helps users move naturally through your website and improves engagement.

Skipping Mobile Optimization

More than 62.54% of web traffic now comes from mobile users (Statista). If your website isn’t optimized for mobile, you’re missing a large audience.

To improve mobile experience:

• Use a responsive design from the start
• Test on multiple devices, not just simulators
• Simplify menus and layouts for smaller screens

When your design fits every device, users stay longer and interact more easily.

Building a Navigation Maze

Navigation is one of the first things users notice. Complicated menus or unclear paths make visitors frustrated and more likely to exit.

Tips for better navigation:

• Keep top-level items to five or fewer
• Use clear and consistent labels
• Add a search bar for quick access

A straightforward structure helps users find what they want without confusion.

Letting Load Times Drag

Pages that take more than three seconds to load risk losing over half their visitors. Speed directly impacts engagement and conversions.

To make your site faster:

• Compress large images and files
• Use lazy loading for off-screen elements
• Remove unnecessary scripts

Faster websites feel smoother and keep users engaged throughout their journey.

Forgetting User Input

Designing without real user feedback leads to products that don’t meet expectations. Ignoring user input also means wasting effort on features no one values.

To prevent this, we should:

• Conduct quick surveys and usability tests
• Monitor heatmaps to understand user behavior
• Continuously refine designs based on results

Small adjustments guided by feedback often lead to lasting improvements.

No Visual Feedback on Actions

If users click something and see no response, they might think it’s broken. Visual feedback assures them that their action worked.

Add these small but effective cues:

• Color changes on buttons when clicked
• Loading indicators for ongoing actions
• Confirmation messages after submission

These visual hints improve confidence and create a sense of smooth interaction.

Mismatching Platform Norms

Users expect apps and websites to behave in familiar ways based on their devices. Ignoring platform norms can make your design feel inconsistent.

To keep it aligned:

• Follow the official design systems of each platform
• Maintain familiar gestures and layouts
• Test across Android, iOS, and web interfaces

A consistent experience across platforms builds comfort and trust.

Weak Typography Choices

Typography affects readability and perception. Fonts that are too small, too fancy, or mismatched reduce clarity and interest.

Good typography practice includes:

• Using no more than two or three font families
• Keeping text size at least 16px
• Maintaining proper contrast for easy reading

Readable text helps users stay longer and absorb information better.

Burying Calls to Action

If your call-to-action (CTA) button blends into the background, users might miss it. CTAs are what drive conversions, so they need clear attention.

Make CTAs effective by:

• Using contrasting colors for visibility
• Placing them where users naturally look
• Keeping the message short and action-focused

Well-placed CTAs guide visitors toward taking the next step easily.

Overlooking Accessibility

Accessibility isn’t optional. When features like alt text or color contrast are ignored, many users including those with disabilities get excluded.

To make your design accessible:

• Add ARIA labels and alternative text
• Follow WCAG standards for color contrast
• Test with accessibility tools regularly

An inclusive website helps you reach everyone and builds goodwill naturally.

Why Getting UI/UX Right Matters?

A well-thought-out user experience can make a big difference in how people connect with your brand. Good design doesn’t just look nice, it helps users feel comfortable, confident, and in control.

When the interface is intuitive, people stay longer, engage more, and are more likely to return. In simple terms, getting UI/UX right means creating experiences that work beautifully for users and bring real value to your business.
