17. MINIMIZE FORM

ERRORS WITH

LABELING AND

REAL-TIME VALIDATION

Label your forms clearly, and make sure the labels are

visible when users are actually entering information - one

participant mistakenly entered his street address into the

email address eld, because only “address” was visible.

Likewise, putting labels inside elds caused problems

if they disappeared when information was entered,

leaving participants without guidance. Once information

is entered, validate it for errors in real time prior to

submission to prevent users from having to resubmit.

Key Takeaway

Use clearly visible labels to let users know what you

need, and validate for errors in real time to let them

know if there’s a problem before they submit a form.
