Choose the reader and the situation
A useful voice guide begins with who is reading and why. The same business may explain a product, resolve a complaint or ask for a booking. The language should fit those situations while keeping the business recognizable. “Friendly and professional” is not enough to choose between two sentences.
Collect actual approved messages and write down what makes them work. Look for sentence length, vocabulary, level of explanation, how questions are answered and how uncertainty is stated. Use your own material with permission rather than borrowing another brand’s distinctive voice wholesale.
Turn adjectives into decisions
If you choose “clear”, specify what it changes: name the product early, use familiar words and explain the next action. If you choose “warm”, explain how to acknowledge a concern without writing an exaggerated emotional promise. If you choose “calm”, remove artificial urgency and unnecessary exclamation marks.
Give each principle a before-and-after example. A writer can apply “Say the dispatch date rather than ‘arriving before you know it’” more reliably than “be reassuring”. Concrete decisions also make an AI brief easier to review.
Separate voice from the facts
A tone setting cannot authorize a price, guarantee or product specification. Keep approved facts, required terms and prohibited claims beside the voice rules. Explain how to handle a missing detail: ask the owner or mark it internally, then resolve it before publication.
Review a generated draft twice. First check whether it sounds like the approved examples. Then inspect every claim independently. A confident, on-brand sentence can still invent compatibility or timing. Style consistency and factual accuracy are different jobs.
Keep the guide short enough to reuse
Use a one-page working guide with a few principles, examples and boundaries. Add channel-specific notes only when they change a meaningful decision. Long lists of generic adjectives can make the writer less certain rather than more consistent.
Update the guide when real messages reveal a problem. Keep an approved version and note why it changed. Store the same guide with campaign briefs so that a launch page, email and social script start from the same choices.
Worked example
Illustrative wording. Replace the details and confirm every claim before using it.
Reader: independent cafe owners considering a menu photo shoot. Voice: direct, warm, practical. Do: name the agreed images, shoot length and price. Do: answer questions with the fact first. Do: explain what is still to confirm. Avoid: “skyrocket sales”, invented urgency and industry jargon. Before: Elevate your culinary storytelling with our bespoke visual solutions. After: Menu photography for independent cafes. A half-day shoot and 15 edited images for £350. Confirm travel, delivery and usage terms before booking.
