Expert writing Tips
Best practice
When offering choices, clarify whether an action is truly optional to avoid confusion or the feeling of missing out. For example, instead of saying "Registration is optional", say "Registration is optional, but it helps us plan better."
Common error
Be careful not to imply that something is unimportant simply because it is optional. Clearly state the benefits of completing the action, even if it's not required. This manages expectations and encourages participation. For example, instead of just saying "Feedback is optional", try "Providing feedback is optional but highly valued as it helps us improve our services."
