Content Style Guide: How to Create One That Your Team Actually Uses
A style guide that lives in a PDF nobody reads is useless. Here's how to create a content style guide that's practical, enforceable, and actually improves consistency across your team.
Every content team has a style guide problem. Either they don't have one (and consistency is accidental), they have one that nobody follows (a 40-page PDF collecting dust), or they have one that's so detailed it takes longer to reference than to just write.
A useful style guide is short, searchable, and enforceable. It answers the questions writers actually ask — "Do we use the Oxford comma?" "Is it 'login' or 'log in'?" "How do we refer to the product?" — without burying those answers in a document nobody has time to read.
What a Content Style Guide Includes
Essential Sections (Start Here)
| Section | What It Covers | Example |
|---|---|---|
| Voice attributes | 3-4 adjectives that describe how your brand sounds | Direct, knowledgeable, approachable |
| Word list | Approved/rejected terms, product names, industry terminology | "Log in" (verb) vs "Login" (noun/adjective) |
| Grammar preferences | Your stance on debated grammar rules | Oxford comma: yes. Sentence fragments: acceptable in headlines. |
| Formatting rules | Numbers, dates, capitalisation, headings | Numbers: spell out one-nine, use numerals for 10+. Dates: 15 March 2026. |
| Content type specs | Requirements per content type | Blog posts: 1,500-3,000 words, H2 every 300 words, meta description required. |
Optional Sections (Add as Needed)
| Section | When to Add |
|---|---|
| Tone variations | When your brand needs to sound different across contexts (marketing vs support vs legal) |
| Accessibility standards | When you have regulatory requirements or a commitment to inclusive content |
| SEO guidelines | When writers are responsible for keyword integration |
| Visual content standards | When writers create or specify images, charts, or video |
| Localisation notes | When content is adapted for multiple regions or languages |
Voice Attributes
Your brand voice is defined by 3-4 attributes. Each attribute needs a definition and Do/Don't examples — not just the adjective.
Voice Attribute Template
Attribute: Direct
| Example | |
|---|---|
| Definition | We say what we mean without hedging, qualifiers, or unnecessary preamble. |
| Do | "Content review takes 2 minutes." |
| Don't | "It should be noted that the content review process typically requires approximately two minutes." |
| Do | "This doesn't work for regulated content." |
| Don't | "It's worth considering that this approach may not be the most suitable for content in regulated industries." |
Attribute: Knowledgeable
| Example | |
|---|---|
| Definition | We demonstrate expertise through specificity, not jargon. We cite data, give concrete examples, and show we understand the reader's reality. |
| Do | "Teams publishing 50+ pieces per month typically see 3x the quality variance of smaller teams." |
| Don't | "Leveraging synergistic content paradigms to optimise holistic quality outcomes." |
Attribute: Approachable
| Example | |
|---|---|
| Definition | We write like a knowledgeable colleague, not a textbook. Conversational where appropriate, never condescending. |
| Do | "Here's what that looks like in practice." |
| Don't | "As the astute reader will no doubt appreciate, the practical implications are as follows." |
Word List
The word list is the most-referenced section of any style guide. Make it searchable.
Format
| Term | Usage | Notes |
|---|---|---|
| TeamBench | Always capitalised, one word | Never "Team Bench" or "teambench" or "Teambench" |
| AI | No periods, no spaces | Not "A.I." or "ai" |
| Lowercase, no hyphen | Not "e-mail" or "Email" (unless starting a sentence) | |
| log in (verb) | Two words when used as a verb | "Log in to your account" |
| login (noun/adj) | One word when used as a noun or adjective | "The login page" / "Enter your login" |
| set up (verb) | Two words as a verb | "Set up your reviewer" |
| setup (noun/adj) | One word as a noun or adjective | "The setup process" |
| real time (noun) | Two words | "Reviewed in real time" |
| real-time (adj) | Hyphenated before a noun | "Real-time scoring" |
| per cent vs percent | Choose one and stick with it | Australian/British English: "per cent". American English: "percent" |
Banned Terms
| Banned | Use Instead | Why |
|---|---|---|
| "Revolutionise" | "Improve," "transform," "change" | Overused, hyperbolic |
| "Best-in-class" | Describe the specific advantage | Meaningless without context |
| "Leverage" (as verb) | "Use," "apply," "take advantage of" | Corporate jargon |
| "Utilise" | "Use" | Unnecessary complexity |
| "Cutting-edge" | Describe the specific innovation | Cliché |
| "Synergy" | Describe the specific benefit | Corporate jargon |
Grammar Preferences
Document your position on every grammar debate your team encounters:
| Decision | Our Rule | Rationale |
|---|---|---|
| Oxford comma | Yes | Prevents ambiguity |
| Sentence fragments | Acceptable in marketing copy and blog posts. Not in formal documents. | Adds rhythm and emphasis |
| Starting sentences with "And" or "But" | Acceptable | Natural and direct |
| Contractions | Yes in blog posts, emails, social. No in whitepapers, compliance docs. | Matches conversational tone |
| Passive voice | Avoid unless the actor is unknown or irrelevant | Active voice is more direct |
| Numbers | Spell out one through nine, numerals for 10+ | AP style convention |
| Headings | Sentence case (not Title Case) | Cleaner, more modern |
Formatting Rules
| Element | Rule | Example |
|---|---|---|
| Dates | Day Month Year, no ordinals | 15 March 2026 (not March 15th, 2026) |
| Times | 12-hour with am/pm, no periods | 3pm AEDT (not 3:00 P.M.) |
| Currency | Symbol before number, no space | $49/month (not $ 49 / month) |
| Percentages | Numeral + per cent (or percent) | 47 per cent (not forty-seven percent or 47%) |
| Lists | Bullet for unordered, numbered for sequential | — |
| Headings | H1 for page title, H2 for sections, H3 for sub-sections | Never skip levels |
| Bold | For emphasis on key terms | Not for entire sentences |
| Italics | For publication names, foreign terms | Not for emphasis |

| Meta description | Required, 150-160 characters |
| CTA | Required, one per post |
| Images | Minimum 1, all with alt text |
Email Campaigns

Keeping the Style Guide Alive
A style guide that isn't maintained becomes inaccurate. A style guide that isn't used becomes irrelevant.
Maintenance
| Action | Frequency |
|---|---|
| Review and update | Quarterly |
| Add new terms | As they arise (don't wait for the quarterly review) |
| Remove outdated terms | When products or terminology change |
| Audit compliance | Monthly — spot-check published content against the guide |
Adoption
| Strategy | Why It Works |
|---|---|
| Make it searchable | Writers need to find answers in seconds, not minutes |
| Keep it under 10 pages | Nobody reads a 40-page guide |
| Include lots of examples | Do/Don't examples are 10x more useful than rules alone |
| Onboard new writers with it | First thing they receive, first thing they're tested on |
| Enforce it automatically | Upload as a Knowledge Base and configure a reviewer to check against it |
Enforcement
The style guide without enforcement is a suggestion document. Three enforcement approaches:
1. Peer review: Writers check each other's work against the style guide. Pros: Builds shared understanding. Cons: Inconsistent, time-consuming.
2. Editorial review: An editor checks every piece against the guide. Pros: Thorough. Cons: Editor becomes a bottleneck; knowledge lives in one person.
3. Automated review: Upload the style guide as a knowledge base and configure an AI reviewer to check every piece against it. Pros: Consistent, scalable, catches every violation. Cons: Requires setup; can't handle nuance.
Best approach: Automated review for consistent elements (terminology, formatting, grammar) + human review for nuanced elements (tone appropriateness, cultural sensitivity).
Frequently Asked Questions
Should we follow AP style, Chicago, or create our own?
Start with an established style (AP for marketing/journalism, Chicago for publishing/academic) and customise. Document only the places where you DIFFER from your base style. This keeps your guide short — you only need to cover your exceptions, not every grammar rule.
How do I get buy-in from writers who resist style guides?
Frame it as support, not constraint. A style guide answers the questions they already have ("Is it 'log in' or 'login'?"), reduces revision rounds (less subjective editor feedback), and makes their job easier (no more guessing what the brand voice should sound like).
Should the style guide be a living document or a formal publication?
Living document. If updating the guide requires a formal approval process, it won't get updated. Use a wiki, Notion page, or shared doc that anyone on the team can suggest changes to (with an editor as gatekeeper).
How detailed should the word list be?
Start with 20-30 terms that cause the most confusion or inconsistency. Add terms as issues arise. A word list of 200+ terms is too long to reference — prioritise the terms that cause the most errors.
What if different clients need different style guides (for agencies)?
Create a master style guide for your agency (your default voice and rules), then client-specific supplements that override the defaults where needed. Upload each client's supplement as a separate knowledge base for their reviewer.
Key Takeaways
- A useful style guide is short, searchable, and enforceable — not a 40-page PDF nobody reads.
- Five essential sections: voice attributes, word list, grammar preferences, formatting rules, content type specs.
- Voice attributes need Do/Don't examples — adjectives alone aren't actionable.
- The word list is the most-referenced section — make it searchable and keep it current.
- Enforce automatically — upload the guide as a knowledge base and configure a reviewer to check against it.
- Review quarterly, add terms as they arise — a stale guide is worse than no guide.
- Under 10 pages — if it's longer, writers won't use it.
