In short
Microcopy is the short text inside an interface, such as button labels, error messages and hints, that guides people through a product.
What is microcopy?
Microcopy covers all the small bits of text in an interface: button labels, form placeholders, error messages, tooltips, confirmations and empty states. Each one is often just a few words. Together, they decide whether a product feels clear and trustworthy.
Unlike marketing copy, its job isn't to persuade. It's to give direction at the right moment. Good microcopy answers questions before people have to ask them: What happens if I click this? What went wrong? What do I do now?
Why microcopy matters
Vague text creates doubt, and doubt costs clicks. A button that just says "Next" doesn't tell anyone whether they're about to pay. An error like "Invalid input" leaves people guessing. At critical points such as sign-up, checkout or cancellation, a handful of words often has more impact than a full redesign. Clear microcopy also cuts support requests, because it answers questions inside the product.
How to use microcopy in practice
- Name the action: "Place order and pay" beats "Continue".
- Make errors fixable: Say what's wrong and how to fix it.
- Address worries early: Notes like "No credit card required" belong right next to the button.
- Stay consistent: Use the same word for the same thing everywhere, and keep a short glossary.
- Test with real people: In usability tests, watch where participants hesitate or ask questions.
Example
An online store for bike accessories shows only "Error in form" when someone enters a wrong postcode. In testing, people spend minutes hunting for the problem. The new message appears right at the field: "Postcodes have five digits. Please check your entry." The confusion disappears without any change to the layout.
