UI/UX Design

UI is the visual design of a site; UX is how the user feels using it and how easy it is to navigate.

UI (User Interface) is the visual design of a website: colors, fonts, buttons, images, and layout. UX (User Experience) is how a user interacts with that interface: how easy it is to navigate, how quickly they find what they need.

Good UI/UX equals higher conversion. Research shows that the ROI of UX investment reaches 100:1 - $100 earned for every $1 invested in UX. Poor navigation causes 88% of users to never return after a bad experience.

UI/UX principles: Fitts' Law (important elements should be large), Hick's Law (fewer choices = faster decisions), visual hierarchy (the most important CTA leads visually), and consistency (color and font systems).

Why it matters

Even if a site looks beautiful, if it's hard to use, visitors will leave and go to a competitor. UI/UX directly affects sales.

Frequently asked questions

Are UI designer and UX designer the same thing?+

No. A UI designer focuses on the visual aspects (colors, images, layout); a UX designer researches user behavior, flow, and usability. Both participate in good projects.

How much does a UX audit cost?+

SaytPro conducts a free mini UX audit for existing sites. Detailed user research plus wireframe design is ordered separately.

Should mobile UI be the same as desktop?+

No. Mobile interfaces need to be designed separately: larger touch areas, simplified navigation, appropriate font sizes for phone screens.
