How to create a style guide your team will actually use

Most content problems aren’t creativity problems. They’re consistency problems.

The blog reads like three different people wrote it because three different people did.

The email uses “enquiry” while the website spells it “inquiry”. One page calls it a free trial, another says free plan.

Nobody is wrong, exactly. They just weren’t working from the same sheet.

A style guide fixes that. And yet, a surprising number of businesses still don’t have one.

Why you need a style guide

A style guide isn’t a bureaucratic box-tick. It’s the document that lets you stop having the same conversation twelve times.

It frees your writers to write instead of second-guess and it frees you to stop editing for preference and start editing for quality.

Here’s what happens without one:

• You grow, you add a second writer, a third, maybe an agency.
• Everyone brings their own habits, instincts and deeply held opinions about whether Oxford commas are civilised or not.
• What arrives in your content calendar starts to feel patchy.
• Readers notice, even if they can’t name why.
• The brand feels inconsistent because it is inconsistent.

A style guide creates a shared reference point that isn’t “ask the most senior person in the room”.

It also pays off internally. Training a new writer takes half the time when there’s a document that answers the questions they’d otherwise ping you about at 4pm on a Friday.

What a style guide should include

The mistake most people make is trying to document everything at once. You end up with a 47-page PDF that nobody opens.

A useful style guide is thorough in the places that matter and light everywhere else.

Here’s what it actually needs.

Brand voice and tone

This is the hardest section to write and the most important to get right. Voice is who you are, tone is how you adapt that depending on context.

Take a B2B software company as an example. Their voice might be: confident, clear and human. No jargon. No filler.

They talk to their customers like colleagues who are smart but busy. But their tone shifts, precise and calm in help docs, encouraging and warm in onboarding emails, direct and benefit-led in ads.

Same company, same personality, different register.

A useful way to make this tangible is to give writers a short “we are/we aren’t” reference:

• We are direct, knowledgeable, conversational.
• We aren’t corporate, preachy, or trying too hard to be funny.

Then back it up with real examples. Pull a paragraph from existing content that nails the voice and one that doesn’t and show writers the difference.

Examples teach faster than a description ever will.

Your audience

Who you’re writing for shapes every decision that follows.

Describe your reader in real terms, what they know, what they care about, what they’re trying to do.

“Our audience is small business owners” is a starting point, but it isn’t much of one.

“Our audience is founders and operations leads at businesses with five to fifty employees, who are comfortable with technology but not developers and who are making purchasing decisions under time pressure” is actually useful.

The more specific this gets, the more useful it becomes when a writer is deciding whether to explain what an API is or just use the term and move on.

Terminology and vocabulary

List the words you use and the ones you don’t.

If your product is a “workspace” not a “dashboard”, write it down.

If your pricing tiers are called Starter, Pro and Business, write those down too, with the capitals intact.

Equally useful is a short list of phrases to avoid. Many brands have words that feel off-brand even if they’re technically fine.

One client I worked with had a blanket rule against “groundbreaking” and “innovative”. Their content was immediately better for it.

Grammar and punctuation preferences

Oxford comma, yes or no? En dash or hyphen for ranges? Sentence case or title case for headings?

These feel like small decisions until you’re editing someone else’s work and realise you’ve got a genuinely different instinct from them.

A practical example, “We help startups, scale-ups, and enterprises” (Oxford comma) vs. “We help startups, scale-ups and enterprises” (without).

Both are grammatically fine. Choosing one and sticking to it is what matters.

Hint, the one without the Oxford comma is the only correct answer.

Same applies to apostrophes in product names.

Is it “Users Guide” or “User’s Guide”? Does the company name take a possessive? Write it down once and stop relitigating it in every edit.

Capitalisation rules

Product names, job titles, department names all develop a gravitational pull toward unnecessary capitals. Decide your rules early.

A common working rule is to capitalise job titles when they’re used as a direct title before a name (“Chief Executive Sarah Chen”), but not when they’re used descriptively mid-sentence (“Sarah Chen is the chief executive”).

Product names are always capitalised, generic descriptions of features aren’t. Your “Dashboard” is a proper noun. “The reporting dashboard” in a general sentence probably isn’t.

Whatever you decide, show the rule in action with a before and after.

“The Marketing Team reviewed the Campaign” becomes “the marketing team reviewed the campaign”.

Obvious in hindsight. Not obvious when your writers have been doing it differently for six months.

Numbers and formatting

Spelling out one to nine, use digits from 10 onwards is a common convention, but whatever you choose, choose something.

I tend to use digits for most numbers as they catch the eye, but it’s entirely up to you how you do it.

A useful worked example for a content team, “We helped three businesses double their revenue” vs. “We helped 3 businesses double their revenue”.

Same goes for dates. Do you write 1 March 2025, March 1 2025, or 01/03/25?

For a UK audience, the last one is a date. For a US audience, it’s potentially March 1st. If you publish internationally, this one genuinely matters.

Link and CTA conventions

Do links open in new tabs? Are CTAs written as commands or invitations?

Compare: “Download the guide” vs. “Find out more” vs. “Click here”.

The first is direct and specific. The second is vague but common. The third is a relic of 2004 web copy that should be retired immediately.

If your brand is action-oriented and clear, “Download the guide” is the right call.

Document it and your writers won’t spend ten minutes second-guessing every button.

SEO and formatting defaults

One H1 per page. Meta descriptions always. Image alt text required. Whether to hyphenate long-tail in running copy. How you handle internal links, anchor text that describes the destination, not “click here” or “read more”.

If you’re publishing content regularly, your style guide and your SEO expectations should live in the same document.

A writer who knows both will produce content that needs far less revision before it goes live.

How to put yours together

I’ve created style guides for businesses across fintech, legal, travel, SaaS and plenty of other sectors, and the process is less mysterious than it sounds.

Start with an audit. Pull ten to fifteen pieces of existing content and look for the inconsistencies.

Those are your gaps. Where you find disagreement, that’s where the guide needs to make a call.

Then write it in plain language, using the voice it describes. A style guide written in corporate boilerplate teaches your writers nothing about how you want to sound.

Keep it living. Set a review schedule, even if it’s just once a year.

Language shifts, products get renamed, audiences change. A style guide that hasn’t been touched in three years starts to work against you.

And for the love of clarity, version-control it. Nothing creates confusion faster than two people working from different copies of the same document.

The part most people skip

Creating a style guide is good. Enforcing it is better.

That’s not a jab at anyone. It’s just the part that actually matters. A document nobody reads is a very thorough waste of everyone’s time.

Share it during onboarding. Link to it in your briefing templates. Reference it in feedback. Make it part of the editorial process rather than a thing that exists in a folder marked “Reference”.

The style guide isn’t the finish line. It’s the foundation.

This is exactly the kind of problem I like untangling.
