Read your website, then read your last few social posts, then open your most recent client email. Do they sound like they were written by the same person? For a lot of service businesses, the honest answer is “not really.” The website sounds formal and polished. The social posts sound casual and a little rushed. The emails sound like whoever happened to write them that day.
None of that is unusual, and none of it means you’re doing anything wrong. It usually happens because your brand voice lives entirely in your head. You know what you sound like when you’re at your best, but nobody has ever written it down. So every time someone else writes for you, whether that’s a team member, a contractor, or an AI tool, they have to guess.
Defining your brand voice fixes that. It turns something that feels like instinct into a short, practical guide that anyone can follow. The result is marketing that sounds consistent, recognizable, and genuinely like you, no matter who’s typing.
What Brand Voice Is (and Isn’t)
Your brand voice is the consistent personality that comes through in your words. It’s not what you say, which is your message. It’s how you say it.
| Brand Element | What It Covers | Example |
| Message | What you say | “We help service businesses get found online.” |
| Voice | Your consistent personality | Warm, direct, practical |
| Tone | How your voice adjusts to the situation | More reassuring in a sensitive email, more energetic in a launch post |
| Visual identity | How you look | Colors, fonts, logo, imagery |
Voice stays steady, while tone shifts with the situation. Think of how you speak with a close friend. Your personality doesn’t change whether you’re celebrating good news or offering comfort after a hard day, but your tone certainly does. Your brand works the same way.
If you’re still working out the bigger picture of your brand, You Already Have a Brand. The Question Is Whether You Chose It. is a good place to start.
Insider Tip from Andrea: A brand voice isn’t something you invent. It’s something you uncover. The best brand voices are simply the clearest, most consistent version of how you already talk when you’re helping a client you care about.
Why a Defined Voice Matters More Than Ever
When you were the only person writing your marketing, your voice stayed fairly consistent on its own. As soon as anyone else gets involved, that consistency starts to slip.
A defined brand voice helps when:
- You hire help, whether that’s a team member, virtual assistant, or contractor
- You use AI tools to draft content and need the results to sound like you
- You’re writing across many channels, from your website to email to social media
- You’re growing, and more people are representing your business
- You want to be recognizable, so your content feels familiar before people see your name
AI tools in particular can produce a lot of words quickly, but without clear guidance they tend to default to a generic, overly polished style that sounds like everyone else. A written voice guide gives those tools, and the people using them, something specific to aim for. For more on keeping your personal touch while using these tools, see our post on using AI in marketing as a tool, not a shortcut.
Step 1: Gather Examples of You at Your Best
Start by collecting writing that already sounds like you. These examples show what your natural voice looks like before you try to define it.
Good sources include:
- Emails where you explained something clearly to a client
- Social posts or articles that got strong, positive responses
- Testimonials, especially phrases clients used to describe working with you
- Transcripts or recordings of talks, podcast interviews, or discovery calls
- Messages you were proud of, even if they were never public
Then gather a few examples that don’t sound like you. Contrasting the two often makes your voice easier to see.
Step 2: Describe Your Voice in Three to Five Traits
Read through your examples and look for patterns. What words would you use to describe how they sound? Narrow your list down to three to five core traits.
Did You Know? Researchers at the Nielsen Norman Group identified four dimensions that shape how a brand’s tone of voice is perceived: funny versus serious, formal versus casual, respectful versus irreverent, and enthusiastic versus matter-of-fact. Placing your brand somewhere along each of these scales is a simple, practical way to start describing how you want to sound.
Try placing your brand on each scale:
| One End of the Scale | The Other End | Questions to Ask |
| Serious | Funny | Do we use humor, and if so, how often? |
| Formal | Casual | Do we sound like a polished report or a friendly conversation? |
| Respectful | Irreverent | Do we challenge conventions playfully or stay measured? |
| Matter-of-fact | Enthusiastic | Do we keep things calm or bring visible energy? |
Most service brands land somewhere in the middle of several of these, and that’s perfectly fine. The goal isn’t to choose extremes. It’s to be clear enough that someone else could write in a way that feels right.
Step 3: Define What Each Trait Means in Practice
A list of adjectives like “friendly, professional, and helpful” isn’t very useful on its own, because almost every business would choose those words. The real value comes from explaining what each trait looks like in actual writing.
For each trait, write down:
- What it means: A short explanation in your own words
- What it sounds like: An example sentence
- What it’s not: The common mistake to avoid
| Trait | This Means | This Is Not |
| Warm | We write like we’re talking to someone we genuinely want to help | Overly sweet, gushing, or full of exclamation points |
| Direct | We get to the point and say what we mean | Blunt, cold, or dismissive |
| Practical | We give people something they can use right away | Abstract theory with no clear next step |
| Confident | We share clear recommendations based on experience | Arrogant, pushy, or full of hype |
The “this is not” column is often the most helpful part of the guide, because it shows exactly where each trait can go too far.
Step 4: Choose Your Words
Small word choices shape how your brand sounds more than most people realize. Create two short lists to guide anyone writing for you.
Words and phrases you use:
- Phrases that reflect how you naturally talk about your work
- The specific terms you prefer for your services and clients
- Expressions your clients have used to describe you
Words and phrases you avoid:
- Industry terms your clients wouldn’t understand
- Overused marketing phrases that sound generic
- Language that doesn’t fit your values or tone
For example, you might always say “clients” instead of “customers,” or avoid phrases like “game-changing” and “next-level” because they feel like hype. These details may seem minor, but together they make your writing feel distinctly yours.
Step 5: Show Before-and-After Examples
Examples teach faster than rules. Include a few short rewrites in your voice guide that show the difference between generic writing and writing in your voice.
| Generic | In Your Voice |
| “We offer comprehensive marketing solutions tailored to your needs.” | “We help you figure out which marketing actually matters for your business, then we do it with you.” |
| “Contact us today to learn more!” | “Want to talk it through? Book a free call and we’ll look at it together.” |
| “Our team is passionate about delivering exceptional results.” | “We care about whether this works for you, not just whether it looks good.” |
Choose examples from the places you write most often, such as your website, emails, and social posts.
Step 6: Note How Your Tone Shifts
Your voice stays consistent, but your tone adjusts depending on the situation. Add a short section to your guide showing how to adapt.
| Situation | Tone Adjustment |
| Website copy | Clear, confident, and welcoming |
| Social media | A little more relaxed and conversational |
| Client emails | Personal, reassuring, and focused on next steps |
| Difficult conversations | Calm, empathetic, and especially clear |
| Announcements and launches | Energetic, while staying genuine |
Step 7: Put It All in One Short Guide
Bring everything together in a simple document of one to three pages. It doesn’t need to be designed or polished. It needs to be easy to find and easy to use.
Your brand voice guide should include:
- A one-sentence summary of how your brand sounds
- Your three to five voice traits, with “this means” and “this is not” examples
- Words and phrases to use and avoid
- A few before-and-after examples
- Notes on how tone shifts by situation
Share it with anyone who writes for your business, and include it when you give instructions to AI tools. If you work with an outside team, a voice guide also makes it easier for them to deliver content that needs fewer revisions. Our post on what done-for-you content actually means explains why that kind of guidance matters.
Test Your Guide Before You Rely on It
Before you hand your voice guide to a team member or an AI tool, test it. The easiest way is to ask someone else to write a short piece using only the guide, then compare the result to your own writing.
Questions to ask when you review the test:
- Does it sound like you, or like a generic version of you?
- Which traits came through clearly, and which got lost?
- Did the writer use any words from your “avoid” list?
- Would a long-time client recognize it as your business?
Wherever the test falls short, add a clearer explanation or another example to your guide. A few rounds of testing usually turn a decent guide into a genuinely useful one.
What Not to Do
These common mistakes make brand voice guides less useful.
- Don’t choose traits you wish you had. Your voice should reflect how you actually communicate.
- Don’t rely on adjectives alone. Examples matter far more than descriptions.
- Don’t make it too long. A guide nobody reads won’t help anyone.
- Don’t copy another brand’s voice. It makes you harder to tell apart.
- Don’t set it and forget it. Revisit your guide once a year or whenever your business changes.

How to Know Your Brand Voice Is Working
Look for these signs once your guide is in use.
- Consistency across channels. Your website, emails, and posts sound like the same business.
- Fewer revisions when others write for you.
- Clients describe you in similar words, often echoing your voice traits.
- Better AI drafts that need less rewriting.
- Recognition. People start telling you your content sounds unmistakably like you.
Where to Start
Gather five pieces of writing you’re proud of and read them side by side. Write down three words that describe how they sound, then add one sentence explaining what each word means for your business. That’s the foundation of your brand voice guide, and you can build the rest from there.
