The elimination of ambiguity. It enables users to see, understand, and act with confidence.
Confusion is the enemy of conversion. If a user has to pause to figure out what a button does or where to find information, trust is eroded. Clear designs reduce cognitive load, prevent errors, and make the product feel faster and more professional.
Use size, color, and spacing to guide the user's eye to the most important elements.
Avoid jargon. Use simple, direct language that users understand.
Provide immediate and clear feedback for every user action.
Use whitespace to separate elements and reduce cognitive load.
Don't overwhelm the user with too many choices at once.
Buttons should say what they do (e.g., "Delete Account" instead of "OK").
Use standard icons that users already recognize.
