Brand voice is the personality your business expresses in every piece of written and spoken communication. It's the difference between two companies that sell the same product but sound completely different — one formal and professional, another warm and conversational. Brand voice is defined by several dimensions: **Personality traits**: What are 3–4 adjectives that describe your brand's character? (E.g., 'expert, direct, human, curious') **Tone spectrum**: Is your default tone formal or informal? Serious or light? Authoritative or collaborative? Note that tone can shift for context — you might be more serious in a complaint response than in a social media post — but voice remains consistent. **Vocabulary choices**: What words do you use deliberately? What words do you avoid? A law firm might avoid casual slang. A youth clothing brand might embrace it. **Sentence structure**: Short, punchy sentences signal confidence and modernity. Long, nuanced sentences can signal thoroughness and expertise. Neither is right or wrong — they're choices. **What you don't say**: Brand voice is as much about restraint as expression. A premium brand never talks about discounts using urgent sale language. A human brand never uses corporate jargon. For SMBs, an inconsistent brand voice is common — especially when multiple people write content. A brand voice guideline document prevents this: it should include example phrases you would and wouldn't use, and show the same message written in-voice and out-of-voice. Actionable tip: Write down the voice of your 3 favourite brands — not in your industry, but brands you personally admire. Note what specific word choices and sentence structures create that feel. This exercise clarifies what kind of voice resonates with you before you articulate your own.
