Take two posts from the same brand, two weeks apart. One is dry and funny. The other is formal, full of “we are delighted to announce”. They read like two different companies. Two different people probably wrote them, and that is exactly the problem.
A brand’s voice is not the easy part of an identity. You decide the logo once. You fix the colours in a file. The voice, on the other hand, has to be defended in every single post, because every post is a chance to lose it.
Voice isn’t the tone of one day
Let’s clear up a common confusion. Voice is the brand’s underlying personality: stable, recognisable, always the same. Tone is how that personality adapts to the moment — warmer for a thank you, flatter for a service notice.
Voice stays. Tone moves. A brand with a dry sense of humour stays dry even when it has bad news: it does it with tact, but it doesn’t turn into a different company. If the personality changes with every piece of content, you don’t have a voice. You have a series of impressions.
Pull it out of what you’ve already written
Voice doesn’t get invented in a meeting with three adjectives on a slide (“we’re young, dynamic, close to the customer” — that means nothing and could be anyone). You find it by looking at real content, the kind that already works.
Take the ten posts that feel most like you. The ones that, rereading them, make you think: there, that’s us. Then look for what they have in common.
- Are the sentences short or long? A neighbourhood bakery that writes the way it talks will have short sentences and plain words. An architecture practice maybe won’t.
- How do you address people? First name and “you”, or something more formal? And do you do it the same way every time?
- Do you use humour? How much? Is there a joke now and then, or is the register always serious?
- Which words keep coming back? Every brand has its own lexicon. Words it uses and words it would never use.
What comes out of this is something concrete. Not “we’re authentic”, but “short sentences, informal address, one joke every three posts, never technical jargon”. That’s a profile another person can follow.
The read-aloud test
There’s a quick check for whether a post is in the right voice. Read it out loud and ask yourself: would the brand actually say this?
It works because it catches autopilot. When you write in a hurry you slide into standard social-speak: the excited announcements, the trailing ellipses, the emoji filling the gap. Sentences that could sit under any logo. If the sentence would work word for word under your competitor’s logo, it isn’t your voice. It’s everyone’s voice, which is the same as nobody’s.
The real problem: more hands on the keyboard
As long as you’re the one writing, the voice holds by itself. The trouble starts when two or three people are posting, or when someone new joins. Everyone brings their own voice, in good faith. And the brand starts speaking with a different accent depending on whose turn it is.
Written guidelines help, but only up to a point: nobody reopens a ten-page document in week three. One page works better, with concrete examples. Not “use a friendly tone”, but two columns — like this / not like this — with real sentences taken from your own posts. Examples teach a voice far better than abstract rules, because they show instead of explaining.
The test is simple: hand that page to someone who has never written for you and ask them for three posts. If they sound like you, the voice is well documented. If they don’t, you’re short of examples.
Where tools help, and where they don’t
Software can learn a voice from the content you’ve already published and reproduce its rhythm and vocabulary in a draft. That’s useful: it removes the blank page and keeps the register consistent even when there are a lot of hands on the keyboard. It’s the problem we’re trying to solve with appost.io — the draft arrives already in the brand’s tone, learned from its real posts.
But voice isn’t only the style of the sentences. It’s also what you choose to say, what you don’t talk about, when to stay quiet. That part stays yours. The tool brings the draft into the right register; the judgement about what deserves to go out is a decision no automation should be making for you. That’s why here the last word always belongs to whoever knows the brand.
In practice
Finding the voice is less creative than it sounds: you look at your best posts and describe, concretely, what they have in common. Keeping it is the hard part, and it all rests on examples — one page of “like this, not like this” is worth ten pages of theory.
And when a post arrives that doesn’t sound like you, trust your ear. If you stopped to read it twice, there’s a reason.
