Brand Content Guide: How to Write One That Your Team Will Actually Use

When several people write for one brand, or when the owner posts on Monday and a freelancer on Thursday, the account starts to sound like different people. One post is formal, the next is full of emojis, the third promises something the business does not do. A brand content guide fixes this: a short document that says what the brand talks about, how it sounds, what it never does and how a post gets from idea to publication. This article shows what to put into it and how to keep it alive, with examples for a small business.

1. What a brand content guide is and who needs one

A brand content guide is the working agreement about how the brand communicates in posts, captions, replies and videos. You need one if:

• more than one person writes or approves content (owner, manager, freelancer, agency);
• you publish in several networks and want one recognisable voice;
• you use AI to draft texts and want results that sound like you and not like everyone;
• you onboard new people regularly and explain the same things again each time.

Even a one-person business gains from it: writing the rules down forces you to decide what you actually stand for. If your focus is visual identity, see our social media style guide; this article concentrates on the content side.

2. The structure of a good guide

Section	What it answers	Length
1. Brand in short	Who we are, for whom, what we promise	5–8 sentences
2. Audience	Who reads, what they want and fear	2–3 portraits
3. Voice and tone	How we sound, with examples	One page
4. Content pillars	What we talk about and what we do not	3–5 pillars
5. Formats and frequency	Which formats in which network, how often	A table
6. Language rules	Words we use, avoid, spelling and punctuation	A list
7. Dos and don’ts	Promises, claims, topics, reactions to criticism	A list
8. Process	Who writes, who approves, how fast we answer	A short flow
9. Examples	Five best posts and three anti-examples	Links or copies

3. Section 1: the brand in short

Write it so that a new employee could repeat it to a customer. Four elements are enough:

• Who we are: “A family bakery in Lisbon making sourdough breads since 2019.”
• For whom: “Neighbourhood residents and offices within 15 minutes.”
• What we promise: “Fresh bread, baked at night and delivered by 8:00.”
• Why us: “Own starter, local flour, no additives.”

This is not a slogan. It is a reference point to check every post: does it support this promise?

4. Section 2: audience in portraits

Describe two or three typical readers in one paragraph each: age range if relevant, situation, what they want, what stops them, where they read you. Use real conversations from direct messages and comments. When you write a post, picture one of these people reading it. A guide with no audience produces a voice that speaks to nobody.

5. Section 3: voice and tone

Voice is the character of the brand; tone is how it adapts to the situation. Describe voice with three to four pairs of “we are X, but not Y”:

• friendly, but not buddy-buddy: we say “you”, we do not use slang;
• expert, but not lecturing: we explain simply, we do not show off terms;
• warm, but not sugary: we thank in a sentence, we do not pile emojis;
• honest, but not harsh: we say “this will not fit you” when it will not.

Then show tone by situation in a table:

Situation	Tone	Example
Announcing a new product	Excited, concrete	“Rye with walnuts is back. Baked on Fridays, 40 loaves.”
Educational post	Calm, helpful	“How to keep sourdough fresh for five days: three steps.”
Replying to a complaint	Respectful, solution-first	“We are sorry about the late delivery. We will bring a replacement today; please share the address.”
Thanking for a review	Warm, short	“Thank you, Anna! We will pass it to the baker.”
Price or policy change	Direct, no spin	“From June, delivery costs 3 euros. Here is why.”

Put five or six real “we say” and “we do not say” phrase pairs under it. These are the most used lines in the whole guide.

6. Section 4: content pillars

Pillars keep topics consistent. For each pillar write: the purpose, three example topics, the best formats and a “never” line. Example for a bakery: Craft and process (how bread is made, ingredients), Useful (storage, pairing), People (the team, customers), Offers (new items, weekend sets). Also write the “not our topics” list: politics, jokes about customers, comparisons with named competitors. For choosing and mixing pillars, read our guide to content pillars.

7. Section 5: formats and frequency

A short table is enough; update it quarterly.

Network	Role	Main formats	Frequency
Instagram	Discovery, visual proof	Reels, carousels, Stories	3–4 posts and daily Stories
Telegram channel	Regular customers, offers	Posts with photos, polls	3–5 posts a week
LinkedIn	Partners, B2B trust	Short expert posts	1–2 a week

A deeper list of formats is in content formats for a content plan.

8. Section 6: language rules

Practical rules save the most editing time. Include:

• Name and spelling: how the brand and products are written, capitalisation, transliteration.
• Words we use and avoid: “order” instead of “purchase”; avoid “unique”, “best on the market” and other empty claims.
• Emoji: allowed or not, how many, which ones.
• Hashtags: a standard set and a limit per post.
• Numbers and currency: formats for prices, dates and units.
• Length: typical caption lengths per network.
• Calls to action: a list of approved ones (“Write to us”, “Book via the link”).

9. Section 7: dos and don’ts

This is the legal and reputation part. Typical items:

• do not promise what we cannot do (delivery times, results, medical or financial outcomes);
• do not publish photos of customers or children without permission;
• show real results only; if an image is generated or edited, say so where needed (see AI content labeling rules);
• respond to criticism within a set time, publicly and politely, and take details to private messages;
• do not argue and do not delete honest negative comments unless they break the rules (abuse, spam);
• do not comment on politics, religion or competitors from the brand account.

10. Section 8: the process

Describe the route of a post in five lines: idea, draft, check, approval, scheduling. Name who does each step and the deadlines, for example: drafts by Wednesday, approval by Thursday noon, scheduling on Friday. Add a short checklist before publishing:

1. Does it fit a pillar and the goal of the week?
2. Are facts, prices, dates and links correct?
3. Is the first line interesting, and is there one clear call to action?
4. Does it sound like us, by the voice section?
5. Are rights to images, music and quotes in order?
6. Is it adapted for the network where it is going?

For teams with a manager or clients who approve posts, see the social media approval workflow.

11. Examples: the part everyone reads

Add five posts that represent the brand at its best, with one line each on why they are good, and two or three anti-examples (“too salesy”, “too long”, “off tone”) with a corrected version. Examples teach faster than any description. Update them every quarter with fresh posts.

12. How to roll out the guide and keep it alive

• Write the first version in an afternoon; do not wait for perfection.
• Test it: ask a colleague or a freelancer to write three captions using only the guide, and see where it did not help.
• Keep it in one shared place and link it in the team chat.
• Review it once a quarter: remove rules nobody follows, add the new ones that came up in disputes.
• Version it: date and a short change note.

13. Common mistakes

• Writing 30 pages nobody reads.
• Describing values (“honesty, quality, care”) without behaviour and examples.
• Copying another brand’s voice.
• No “do not” list.
• A guide for the networks you used two years ago.
• Not applying it to AI drafts, which then sound generic.

14. How AI SMM helps

The AI content studio works from your brand’s information: you describe the business, the audience and the voice once, and drafts and images follow them, which is exactly where a written guide pays off. Your “we say / we do not say” lines and your pillars are the best input you can give it; see how to train AI on your brand voice for the steps. In the planner the team sees the calendar with all networks, so the “formats and frequency” table turns into scheduled posts, and the approval step before publishing keeps the checklist honest. Replies to comments and messages in networks that have an inbox come in one shared inbox, where the tone rules for complaints are put to use every day.

FAQ

How long should a brand content guide be?

Two to six pages are enough for a small business. If it is longer, add a one-page summary at the top.

What is the difference between a content guide and a style guide?

A content guide covers what and how we say; a visual style guide covers how we look: logo, colors, fonts, photo style. Many teams combine them into one document with two parts.

Can a one-person business skip it?

You can write a shorter version: voice, pillars and a “never” list on one page. It saves time when you start using templates, AI drafts or a freelancer.

How do I get people to follow it?

Make it short and example-driven, use it in actual review comments (“see section 3”) and update it when people point at a rule that does not work.
