How to Brief a Writer (or an AI) So the Post Sounds Like Your Business
Adjectives in a brief produce nobody's voice — hand over positions, refusals and real numbers instead, then run the competitor swap test on every draft.
By FluxWriter
A writer brief is the cheapest control you have over whether a post sounds like your business or like every competitor on the same keyword list. Most owners hand over a topic, a word count and the word "professional", then spend an hour editing a stranger's voice out of the draft. This covers the five inputs a brief needs, why adjectives never work, and a ten-minute test for whether the draft sounds like you.
Why "Friendly but Professional" Produces Nobody's Voice
The standard tone line in a brief is some version of friendly, professional and approachable. Every one of your competitors wrote the same three words. A writer or an AI model given that instruction does the only sensible thing and aims for the middle — and the middle is where every generic post already lives.
Adjectives describe how a reader should feel. They give the writer nothing to decide with. "Confident" does not tell anyone whether to quote a price or admit that a job under a certain size is not worth taking.
That's the actual problem. Voice is not a texture applied at the end. It is the sum of the positions a business is willing to take in writing, and a brief that contains no positions produces a post that takes none.
The cost shows up in the edit. Adjective briefs typically buy you 45–90 minutes of rewriting sentences that are technically fine and completely interchangeable. Position briefs buy you 10–20 minutes of fact-checking. Same writer and fee, a different hour.
What a Voice Actually Is
Strip the mystique out and a business voice is made of three things a stranger cannot guess.
Positions are the opinions you already give on sales calls. A roofer who tells every customer that a 20-year shingle is a false economy on a coastal house has a position. Written down, it separates that roofer from the other 30 in the county whose blogs say roofs are "important to maintain".
Refusals are the jobs, customers or claims you turn away. A bookkeeper who will not take clients with more than three months of uncategorised transactions has a refusal, and it says more about how the business operates than 500 words about values.
Specifics are the numbers only you have. Your real prices, your actual turnaround, the fact that 4 of every 10 quote requests come from a referral. Generic content has to hedge because it does not know. You do not have to.
Read the next draft with those three in mind and count. Zero usually means the writer was never given any, and the fix is upstream of the writer.
The Five Inputs Every Brief Needs
A useful brief is mostly raw material, not instruction. The writer's job is assembly. Yours is to hand over the parts nobody else can supply, and each one takes less time to gather than it sounds:
| Input | What to hand over | Time to gather |
|---|---|---|
| Customer questions | 5 real questions, in the customer's exact words | 10 minutes from your inbox |
| Your positions | 3 things you believe most competitors get wrong | 15 minutes |
| Your numbers | Prices, ranges, timelines, minimums | 10 minutes |
| Word rules | 5–10 words you never say, 5–10 you always use | 10 minutes, once |
| One sample of you | A quote email or proposal you actually sent | 5 minutes |
The second row changes the draft most. Questions tell the writer what to cover — positions tell them what to say, and that gap separates a brochure from a post a customer forwards to a partner.
The last row matters more than owners expect. One real email you wrote, with the hedges and the blunt bits left in, teaches sentence length and formality faster than any description of them. Pick the one that closed a deal.
Word rules are the smallest input and the first thing a reader notices — a dentist whose post says "clients" instead of "patients" sounds wrong to their own front desk by paragraph two.
The Competitor Swap Test
The fastest check takes about ten minutes and requires no taste. Read the draft and replace your business name with your nearest competitor's. Then ask whether they could publish it unchanged.
If the answer is yes for the whole post, the brief failed. Mark every sentence a competitor could not honestly publish — a price they do not charge, a refusal they do not make. Count them. A 1,400-word post should carry at least 8–12 of them, roughly one per section, and the strongest carry one per paragraph. Under 8 goes back for another pass. Under 5 is inventory, not marketing.
"Quality workmanship at a fair price" survives the swap on any roofer's site. "No 20-year shingle within two miles of the coast, and the estimate says why" survives it nowhere but yours.
Run the test on your existing posts first. On most small-business blogs the large majority survive the swap untouched — which is the honest reason the blog earns traffic but never a phone call. Traffic notices topics. Customers notice positions.
The test also catches the opposite failure. A claim you would not repeat to a customer's face has to go, however well it reads, because a bland sentence only loses a reader and a promise you cannot keep loses a refund and a one-star review.
Briefing an AI Versus Briefing a Person
The five inputs are identical. What changes is how they are delivered, and where each kind of writer fails without them.
A freelance writer needs the "why" once and the numbers every time. Explain the positions in a 30-minute call at the start, and a good writer will carry them across 20 posts. Skip the numbers on post 12, though, and they will hedge or guess — and a guessed price is the single most expensive error a post can contain.
An AI model needs everything in the brief, every time. There is no memory of last month's call unless the tool you use stores a standing profile. Paste the positions, the numbers, the word rules and the sample into each request. Left without them, a model reaches for the statistical average of every post on the topic — precisely the voice you are paying to avoid.
Two failure modes are specific to AI. The first is invented numbers. State plainly that any figure not supplied in the brief must be left as a bracketed placeholder for you to fill. The second is manufactured balance — a model will present both sides of a question you have already decided. Give it the position, and tell it the post takes a side.
Human writers have their own version. Told "casual", a person over-corrects into jokes you would never make in front of a customer. Told "authoritative", they reach for a textbook. The sample email fixes both — it shows where you actually sit on that scale.
Where the Time Goes and What It Buys
Briefing feels like an overhead until you price the alternative. The standing part of the brief — positions, refusals, word rules, one sample — takes most owners 60–90 minutes to build the first time. It does not need rebuilding. The per-post part, five customer questions plus any topic-specific numbers, runs 10–15 minutes after that.
Set that against the edit. A thin-brief draft costs 45–90 minutes of your time to fix and often still reads like everyone else. A full-brief draft costs 10–20 minutes to check. Across 24 posts a year, that gap is somewhere between 10 and 30 hours of your own time, before counting the posts that finally earn a call instead of a visit.
That is the whole decision — and the rewriting never compounds, while the brief does.
Assign the standing brief to yourself. Delegate the per-post part to whoever answers your customer email — they already hold the questions.
FAQ
Can I just send my writer three competitor posts I like as the example?
No, and this is the most common way to end up sounding like someone else on purpose. Competitor posts teach the writer a competitor's positions and vocabulary. Use them only to mark what you would have said differently — those margin notes are the brief. Send one piece of your own writing as the actual sample.
My writer says taking positions will put customers off. Are they right?
Only about the customers you were going to turn away anyway. A position that loses a bargain-hunter you would never take on costs nothing and saves a call. The test is whether you would say it to a prospect on a site visit. If yes, publish it. If not, it is a pose, not a position.
What if I don't have strong opinions about my industry?
You do, and they surface on sales calls rather than in writing. Listen to yourself explain why a customer should not buy the cheapest option, or why a job takes 3 weeks and not 1. Every "because" in that explanation is a position. Write down 3 and the brief is most of the way there.
The Practical Takeaway
Build the standing brief once this week: 3 positions competitors get wrong, 2–3 things you refuse to do, your real prices and timelines, 5–10 banned words, and one email you actually sent to a customer. For each post, add 5 customer questions in their own words and any topic-specific numbers — 10–15 minutes. Run the competitor swap test on every draft and send back anything with fewer than 8 sentences only you could publish. Start with the next post in your queue, not the whole library.
If you are producing posts from that kind of brief on a regular schedule, tools like FluxWriter can help keep the standing profile applied across every draft instead of pasting it in each time — but every position and every number in it still has to come from you, and no tool can supply an opinion you have not formed.
