Extreme TLDR:
Improve microcopy by ensuring it’s role-playable, clear, and concise. Use friendly dialogues, be transparent on sensitive topics, and reflect actions in button labels. Provide clear reasons for actions, avoid explaining UI interactions, and limit each message to one idea. Use relatable examples, avoid negatives, and eliminate jargon. Ensure titles and buttons are understandable without body text, and always lead with important info. Use specific terms consistently and keep error messages straightforward. Aim for a smooth user experience and collaborate with designers for effective microcopy creation.
