The rule
Sequence information using progressive disclosure to guide users through the process without overwhelming them.
Why it matters
Long forms and cluttered onboarding screens create friction that may cause users to abandon the product for a competitor. Presenting only the necessary information at each step reduces the user's cognitive load. Clear instructions and "helping hands" like tooltips ease insecurities during a user's first impression.
How to apply it
- Separate labels from placeholders; labels must remain visible even after the user starts typing.
- Clearly mark required fields using asterisks or the word "optional".
- Group related fields together and use progress bars to show how much of the process remains.
- Front-load the value proposition at the start of the onboarding flow.
Example
Weak
(Instruction in a placeholder) "Password (Must be 8 characters)"
Stronger
(Instruction beneath the label) "Password / 8+ characters"
Tensions and exceptions
While brevity is a goal, sometimes doubling the number of words in a form by adding assistive copy actually increases completion rates by providing the reassurance users need at friction points.
