Tone of voice

Tone of voice is the recognisable way a brand communicates: its words, style, attitude. Kept consistent across all content, it makes a business memorable and distinguishable. It can be warm and friendly, professional, or witty: what matters is that it stays consistent and fits the audience.

Tone of voice is how your business talks: the words you choose, the rhythm of your sentences, how formal you are, what you allow yourself to say and what you don't. It isn't the logo and it isn't the message, because that's the 'what'. Tone is the 'how'. If a customer read three of your captions without seeing the profile name, they should still recognise you. When that happens, you have a tone of voice. When it doesn't, you're just posting text.

For a small business, voice helps make the difference. A neighbourhood hairdresser can't win on price against a chain, but can win on familiarity: readers feel there's a person behind it, not a marketing department. A defined tone also saves you time, because you stop starting from scratch with every post and just ask yourself one question: would I actually say this sentence to a customer sitting in the chair?

In practice tone rests on a handful of repeated choices. Formal or informal address. Short sentences or long ones. Jokes or staying reserved. Calling things what customers call them: 'blow-dry' instead of 'styling session', 'eyebrows' instead of 'brow architecture'. Emoji or none. They're small decisions, but made once and kept, they become a signature. Made at random each time, they become noise nobody connects to you.

The fastest way to find it isn't a branding exercise: it's listening to yourself. Record a voice memo explaining to a customer why you recommend a certain treatment, then transcribe it. Your tone is already in there, with your recurring words, your way of reassuring, your jokes. The work isn't inventing a new voice, it's cleaning up the one you already have and making it repeatable even when you're not the one writing.

Tone, then, also decides what you don't post. A pizzeria that's chosen to be direct and homely will never write 'culinary excellence of the territory', because it clashes with everything else. Having a defined voice gives you an instant filter: if a sentence doesn't sound like you, cut it.

How to put it into practice

Write your voice sheet

On a sheet, note: formal or informal, three words you always use, three you'll never use, emoji yes or no, typical sentence length. Keep it in front of you while writing and revise it after a month of testing.

Start from a voice memo

Record yourself explaining a service out loud to a customer, transcribe it, and underline the sentences that sound like you. Use those as the base for your first three captions, without translating them into marketing-speak.

Try the covered-name test

Take five of your captions, cover the profile name, and have a regular customer read them. If they can't tell they're yours, you're still missing some word or writing habit typical of how you actually talk.

Put it all in writing before delegating

Before handing posts over to an assistant or a tool like Carosell, give them your voice sheet: three examples of your sentences and the words to avoid. That way whoever writes for you starts from your voice, not from scratch.

Common mistakes

  • Writing like a press release ('our salon is pleased to announce') when in the shop you talk to customers simply and directly.

  • Changing voice with every post: witty one day, motivational the next, then technical. Followers can't tell who you are and stop recognising you.

  • Copying the tone of an American account with millions of followers: what works for an influencer doesn't work for the pizzeria on your street.

Frequently asked questions

Should I address customers formally or informally?+

Look at how you talk to them in person. If you're informal in the shop, being informal online is consistent. If you work with a more formal, appointment-based clientele, formal isn't old-fashioned. There's really one rule: pick one and don't switch halfway.

Can I use a different tone on Instagram and TikTok?+

Yes, but it should be the same person at two speeds: faster and more informal on TikTok, more polished on Instagram. But if you're witty on one channel and sound like a law office on the other, people who follow you on both struggle to recognise you.

If I have AI write my posts, does the tone stay mine?+

Only if you give it to the AI. An AI doesn't know how you talk: it needs to be trained with examples of your sentences, words to use and words to avoid. Give it three captions written in your own hand, ask it to stick to that register, and always reread before posting.
