Lessons

3 lessons, in order.

0/3
  1. Lesson 1: Label the field before asking for data

    Use a persistent visible label for the input purpose and add a description only when the shopper needs context, constraints, or consequences.

  2. Lesson 2: Write CTA copy from the action

    Name the action and consequence so the shopper knows what the button will do.

  3. Lesson 3: Write errors as recovery instructions

    State what went wrong and the next valid action in calm, specific language without blaming the shopper.

Microcopy carries interface meaning. Labels identify what information is needed, CTA copy states the consequence of an action, and errors explain how to recover. The business outcome is fewer ambiguous states, not a collection of clever phrases.

These decisions belong together because the same words must agree before, during, and after an action. A field label sets an expectation, the CTA commits the input, and the response confirms success or identifies the exact correction. W3C accessibility guidance says purpose should be evident and visible labels should align with corresponding names in code, including for voice input.1

Write from the interface state

Begin with the real data requirement and system behavior. Name the field in the shopper's vocabulary. State constraints before they cause errors. Write the CTA from the immediate action and consequence. Write errors from the problem and the next valid step.

Brand voice can shape tone, but it cannot obscure function. The higher the commitment, such as placing an order or subscribing, the more literal the control should become.

Module diagnostic

Trace one task and capture:

  • label and description;
  • example or format hint;
  • primary CTA and accessible name;
  • loading or pending state;
  • success confirmation;
  • validation and system errors;
  • recovery action.

Read the sequence without the visual design. If the next action or consequence becomes unclear, the microcopy is relying on layout to carry missing meaning.

Assignment

Rewrite one task chain as a state table: trigger, user action, system result, visible words, accessible name, and recovery. Then test whether an unfamiliar person can predict the CTA result and recover from a realistic error without explanation.
