Keeping One Brand Voice When Multiple People Are Writing Your Content

06 September 2026·5 min read

Quick answer: One brand voice across multiple writers isn't about everyone writing identically — it's about everyone working from the same short reference sheet of words to use, words to avoid, and a couple of sample sentences that sound "right." Give your team a one-page voice guide and a five-point review checklist, and posts stop reading like three different businesses took turns. ✨

You can usually tell the exact week a second person started posting to a business's Instagram. The tone shifts — one post is chatty and full of exclamation marks, the next is stiff and corporate, and a customer scrolling through both wonders if they've followed two different accounts. This isn't a writing-talent problem. It's a reference problem — nobody wrote down what "sounding like us" actually means. 💖

What most businesses get wrong

The usual approach is verbal: the owner tells a new hire to "just keep it casual and friendly," or "make it sound like us," and leaves it there. That instruction means something different to every person who hears it. One person's "casual" is lowercase and full of slang; another's "casual" is still opening every caption with "Hi there,". Without a written reference — actual example words and sentences — everyone is guessing at a moving target, and the guesses drift further apart the longer multiple people write without checking in.

ONE-PAGE VOICE & TONE REFERENCE (copy and fill in)

We sound like: [3 adjectives, e.g. "warm, direct, a little cheeky"]
We never sound like: [2-3 things to avoid, e.g. "corporate, apologetic, overly formal"]

WORDS WE USE → WORDS WE AVOID
"Grab" → "Purchase"
"Sorted" → "Finalised"
"You'll love" → "We are pleased to offer"
"Quick heads up" → "Please be advised"
"Because..." → "Due to the fact that..."

SAMPLE SENTENCE (right): "New stock just landed and it's going fast — grab yours before the weekend."
SAMPLE SENTENCE (wrong): "We are excited to announce the arrival of new stock, available for purchase while supplies last."

BEFORE YOU POST, CHECK:
1. Would our founder actually say this sentence out loud to a customer?
2. Does it use any word from the "avoid" list?
3. Is there at least one contraction (don't, it's, you'll) if the rest of our voice uses them?
4. Does the sign-off/CTA match how we usually close a post?
5. Read it out loud once — does it sound like a person or a press release?

Growing retail business, two staff posting to Instagram: One team member writes punchy, exclamation-heavy captions; the other writes longer, descriptive ones. After building a one-page reference together — including sample sentences pulled from their best-performing past posts — engagement on captions becomes noticeably more consistent within a month.

Business owner training a new marketing hire: Instead of a week of "that's not quite our voice" edits, the owner hands over the one-page reference plus five real past posts marked "yes, this" and two marked "no, not this." The new hire's first drafts land close to on-brand from week one.

How to build and actually use it

1. Pull five of your best past posts. Not the ones you think should represent the brand — the ones that performed well and felt right when you read them back. Patterns in these are your real voice.

2. Write down three adjectives, then test them. "Friendly, honest, a bit playful" is only useful if you can point to a sentence and say "that's playful, that's not." Attach an example to each.

3. Build the do/don't word list from real mistakes. Look at posts that didn't sound like you and pull out the specific words that felt off — corporate filler like "in today's fast-paced world" is a common culprit.

4. Put the checklist where people actually post from. Pin it in the scheduling tool or shared drive — not buried in a document nobody reopens after week one.

5. Review as a pair, briefly, for the first month. Have whoever's more confident in the voice glance at a new writer's first few posts before they go live — five minutes, not a full edit.

💡 Consistency beats cleverness. A slightly plainer voice used the same way every time builds more recognition than brilliant, unpredictable copy that changes with whoever's typing.

Mistakes to avoid

Describing the voice only in adjectives, with no examples. "Friendly and professional" means something different to everyone — always pair adjectives with an actual sample sentence.
Making the reference too long to use in practice. If it's more than a page, nobody will check it before hitting post.
Only writing down what to avoid, never what to use. A list of banned words with no approved alternatives leaves writers stuck rewording the same sentence.
Skipping the review step once the guide exists. A written guide reduces drift, but a quick second read for the first month is what catches it early.
Treating the guide as permanent. As the brand's audience or offering shifts, revisit the reference every six months rather than assuming it's set in stone.

Frequently asked questions

How long should a brand voice guide actually be?

One page. If it needs a table of contents, it's too long for a small team to reference in the two minutes before posting.

What if the two people writing content genuinely have different natural styles?

That's normal, and the goal isn't to erase personality — it's to agree on the boundaries so both styles still fit inside one recognisable voice.

Do we need a professional copywriter to write the voice guide?

No — the best source material is your own best-performing past posts. A copywriter can help articulate patterns you've already got, but you don't need one to start.

Will a voice guide fix inconsistent content on its own?

Honestly, not entirely — it's a strong reference, not a guarantee. Someone still needs to glance over new content occasionally, especially in a new writer's first month. Treat it as a big reduction in drift, not a fix-and-forget solution.
