Microcopy
Short interface text, such as button labels, field hints, error messages and confirmations, that guides users through a task.
These few words sit exactly where users decide to continue or quit, such as signup, checkout and error states, so clearer wording can lower abandonment and support tickets at a fraction of the cost of a redesign.
A trial signup form changes its button from 'Submit' to 'Start free trial', adds 'No credit card required' below it and rewrites the password error to name the missing rule; the team compares completion rates over two weeks.
Better wording cannot fix a broken flow, and clever or humorous copy wears thin with repetition or confuses users under stress. Gains from copy tests are often small and need enough traffic to measure reliably.
Microcopy includes labels, placeholder and hint text, Call to Action (CTA) buttons, error and empty-state messages, tooltips and confirmations within the User Interface (UI). Common guidance is to use plain, specific words, place errors next to the field that caused them, explain how to fix the problem without blaming the user and avoid instructions that rely on color or position. Teams keep it consistent through a content style guide and test changes with A/B tests or usability sessions.
