Your brand has a voice whether you choose it or not
Every piece of writing your business publishes has a tone. The website headline, the Instagram caption, the error message, the invoice email, the proposal. If nobody has decided what that tone should be, it ends up as a mix of whoever wrote each piece: formal in one place, chatty in another, stiff and corporate somewhere else.
Customers notice. A brand that sounds different everywhere feels less coherent and less trustworthy, even if every individual piece is well written.
Tone of voice affects trust
The Nielsen Norman Group, one of the most respected user-experience research firms, has studied this directly. They describe tone of voice along four dimensions:
- Funny or serious
- Formal or casual
- Respectful or irreverent
- Enthusiastic or matter-of-fact
Most brands sit somewhere between the extremes on each one. Defining where you sit is the first step to sounding consistent.
In a follow-up study, NN/g tested different tones on websites in industries including banking, insurance, security, and healthcare, and measured how users perceived each brand's friendliness, trustworthiness, and desirability. A few findings stand out:
- Casual, conversational, and moderately enthusiastic tones performed best overall.
- Trustworthiness mattered most. It was a much stronger predictor of how desirable people found a brand than friendliness, explaining 52% of the variation in desirability scores.
- Humour is risky. A playful, irreverent tone could make a brand feel friendlier while undermining how trustworthy and professional it seemed. When humour fails, it annoys and alienates.
For most businesses, the lesson is to sound warm and human, but never at the expense of credibility.
Voice and tone are different
It helps to separate two ideas.
Voice is your brand's personality. It stays the same everywhere. If your brand is calm, clear, and expert, it is always calm, clear, and expert.
Tone is how that voice adapts to the situation. You might be lighter in a social post, more precise in a contract, and gentler when replying to an upset customer. The person is the same; the mood fits the moment.
How to define your brand voice
1. Start from your brand strategy. Your voice should express who you are and who you serve. A builder of premium family homes, a fintech product, and a children's tutor should sound very different.
2. Choose three to four voice traits. For example: clear, warm, and quietly confident. For each, add a line on what it means and what it does not. "Confident, not arrogant." "Warm, not overly casual." The "not" is what makes a trait usable.
3. Place yourself on the four dimensions. Decide roughly where your brand sits between funny and serious, formal and casual, respectful and irreverent, enthusiastic and matter-of-fact.
4. Write a word list. Words you use, words you avoid, and how you refer to your customers and your work. Small choices, like "clients" or "customers", "we" or "the company", add up.
5. Show before-and-after examples. One rewritten paragraph teaches a writer more than a page of rules. Show a generic sentence and the same idea in your voice.
6. Describe how tone shifts. Give guidance for your main situations: website, social media, sales, customer support, and difficult messages.
Common voice mistakes
- Sounding like everyone else. "Innovative solutions", "passionate team", and "customer-centric approach" could belong to any company.
- Writing to impress instead of to be understood. Jargon and long sentences make readers work harder and trust you less.
- Forcing humour. As the research shows, a joke that misses costs credibility.
- Being inconsistent across channels. A friendly website and a stiff, legal-sounding email signal two different companies.
Voice for founder-led brands
For many businesses, the most natural brand voice is the founder's own, refined. It already carries the warmth and conviction customers respond to. The challenge is capturing it in a way other writers can follow, so that the brand still sounds like the founder when someone else is writing. That is the heart of the work we do at The Draftory: learning how someone talks and thinks, then writing so that the writer disappears.
The bottom line
How your brand sounds is as much a part of your identity as how it looks. A clear, consistent voice makes every piece of writing more recognisable and more trustworthy. Define it deliberately, write it down, and use it everywhere.
If your brand sounds like a different company on every channel, our content and marketing team can help you find one voice and keep it.
