UI – User Interface
The visual design of the site — colors, typography, icons, layout, spacing. Good UI guides the eye, creates visual hierarchy, and builds trust. Poor UI confuses and repels.
In practice
UI is the 'visual language' that speaks to a visitor before they read a word. Colors: blue signals trust, orange signals urgency. Whitespace signals luxury. A cluttered design signals low price. A luxury store with a 'cluttered' design sends the wrong message.
Common misconception
'UI is just decoration — it doesn't affect sales.' Stanford research found 75% of users judge a company's credibility by its site design. Poor UI means low trust means low CR. Sometimes improving UI (images, layout, whitespace) increases CR more than a price change does.
How to fix it
UI falling short? (1) Use a color contrast checker — is text readable? (2) font size: minimum 16px for body text, (3) whitespace: is the page too crowded? (4) consistency: are buttons, colors, and fonts uniform across the site? (5) image quality: high-resolution photos with professional lighting.
Example
A jewelry store had an outdated UI, gray-background photos, and a hard-to-read font. A redesign with white-background photos, a clean font, and more whitespace raised CR from 0.9% to 2.1% with no change in price or traffic — UI alone.
Priority
Run a UI audit: look at the store on someone else's screen. What's the first impression? Does it look professional? Are the images high quality? For new stores: invest in professional photography before any advertising — high ROI.
