When to Use

Reviewing copy for tone consistency.
Localizing copy for new regions or verticals.
Training new writers or agencies on brand standards.

Framework

Voice Pillars – e.g., confident, empathetic, pragmatic (with examples).
Tone Ladder – how tone shifts by channel, funnel stage, or audience.
Style Rules – grammar, punctuation, casing, formatting, banned phrases.
Accessibility – reading level, inclusive language, jargon policy.
Localization Notes – regional terminology, regulatory statements, measurement units.

Templates

Do/Don’t example library.
Localization matrix (region, language, required changes).
Voice feedback form (issue, recommendation, owner).

Tips

Revisit guidelines quarterly; align with positioning updates.
Pair with message-architecture for consistent structure.
Track exceptions (e.g., partner co-branding) to avoid conflicting signals.
