Microcopy is the tiny bits of text in a website or app: the label on a button, the hint under a form field, an error message, a tooltip, the line on an empty cart. Each piece is only a few words, but together they decide whether people move through your site confidently or stop and wonder what to do.
Where microcopy lives on a typical site
- Buttons and links: "Book a cleaning", "See all menus", "Download price list".
- Form labels and placeholders: what to type and in what format.
- Helper text: answering the worry before it stops someone, such as why you need a phone number.
- Errors and validation: what went wrong and how to fix it.
- Empty and loading states: what to do when there is nothing to show yet.
- Confirmations: what happened and what comes next.
Why a few words change behaviour
People hesitate at moments of uncertainty: "Will this charge my card now?", "Will they spam me?", "Did my message actually send?" Microcopy answers those questions at the exact spot they arise. A line such as "No payment until you approve the quote" placed under a request button removes the specific doubt that would otherwise end the visit. That is why microcopy sits at the sharp end of UX writing: it is the part people read with their finger already on the button.
A real-world pattern: password rules
A common failure is a sign-up form that rejects a password with "Password does not meet requirements" after submission. Better microcopy lists the rules beside the field before typing (for example "At least 8 characters"), ticks each one as it is met, and never makes the person guess. The rules are identical; only the wording and timing changed, and the frustration disappears.
When to spend time on it
For most small sites, review microcopy in three places: the main call-to-action buttons, every form, and the page shown after a form is sent. If your contact form produces leads that never call back, or your shop has abandoned checkouts, read every word on those screens as a stranger would. Changing text is free and takes minutes.
Microcopy mistakes
- Placeholder instead of label. Grey placeholder text disappears as soon as someone types, so they forget what the field was for.
- Generic errors. "Something went wrong" with no next step leaves people stuck.
- Jokes in the wrong place. A playful tone on a failed payment message feels dismissive.
- Silent success. A form that clears itself with no confirmation makes people send it again, or assume it failed.
