Your tone of voice determines whether your target audience trusts you—and, therefore, whether they become customers. Yet when most companies think of tone of voice, they immediately think of “the right tone for each country.” But your tone doesn’t just vary by market—it also varies depending on the persona reading your text and the stage of the customer journey that person is in. In this blog, you’ll learn how to strike the right chord on all three levels, with concrete examples, ready-to-use prompts, and tips on how to use AI and smart translation software to keep your brand voice consistent everywhere.
What is tone of voice, and why does it affect your revenue?
Tone of voice is the way your brand sounds: your choice of words, how direct or formal you are, and how much evidence you provide. It’s the personality behind your copy. If it sounds like someone your target audience trusts, you’ll reduce their hesitation to buy. If it sounds even slightly off, people will tune out—no matter how accurate the text is. So tone of voice isn’t just about flowery language—it’s about trust, and trust drives conversion.
Why this matters specifically on your website
Your website is usually the first real point of contact: the place where a visitor arrives from an ad, Google, or an AI response. By that point, you’ve already invested time and money into bringing that visitor to your site. At that very moment, your tone determines whether they’ll keep reading and take action—or click away. So the wrong tone wastes exactly the traffic you’ve worked hardest to acquire, no matter how sleek your design is or how well you rank in Google and AI. And unlike with an ad or email campaign, which you can segment by target audience, different personas are reading the same pages on your site at the same time. Your tone on the website must therefore cleverly accommodate those differences.
Tone of voice varies across three levels
The same service, the same core message, but the way you convey it changes on three levels at once. If you mix these up, you’ll end up writing copy that’s “for everyone” and therefore doesn’t really resonate with anyone.
- Per persona — who is reading this, and what does that person want to hear?
- By customer journey stage — is the customer still exploring options, or is he about to make a choice?
- By market —in which country and culture is the message being conveyed?
Most companies focus only on that third layer (translation by country) and overlook the first two. That’s precisely where the greatest gains can be made, even if you operate in just one market.
Layer 1: Tone varies by persona
Within each market, very different people read your text. An owner-manager wants to hear something different than a marketing manager at a larger company, and a loyal small-business client wants a different tone than a startup that has just discovered you. The same service, a different angle for each reader. Here’s how that translation works for the five customer types we serve every day at JKC:
| Who reads your text? | What he wants to hear most of all | Which note lands | What turns him off |
|---|---|---|---|
| The Growing Entrepreneur (Owner-Manager, 10–100 employees) | Results and convenience: less hassle, more requests, a single point of contact | Straight to the point, concrete, no jargon | Vagueness, fancy words, “a pretty picture” with no substance |
| The marketing manager at a larger organization | Evidence and process that will allow her to make an impact internally (with senior management, IT, and legal) | Professional and well-reasoned, with data and a clear approach | Empty claims—something she can't pass on |
| The international growth company (operating across borders) | That you can succeed in any market and truly be present there | Ambitious and concrete, in markets and growth paths | "Home market-only" mindset, small, scattered country offices |
| The Smart Starter (Just Starting Out, Small) | Get online quickly and professionally, with no hassle and no surprises | Accessible, clear, honest (including “you don’t need this yet”) | Jargon, unclear pricing, and only calling back for large budgets |
| The long-standing SME customer (small business, has been a customer for years) | That he still counts and that it just keeps working | Warm, personal, reassuring, never patronizing | “Making things too big or too expensive,” the feeling of having become too small |
Note: It’s one brand and one promise, but with five different emphases. That doesn’t mean presenting five different faces; it means ensuring the same message resonates with whoever reads it.
Layer 2: Tone varies by customer journey stage
What’s more, that same persona is at a different stage of their customer journey each time. Someone who has just discovered you wants to hear something different from someone who is comparing providers or is about to make a choice. Your tone should shift depending on the stage:
| Stage in the customer journey | What the Reader Wants | The Impact of Your Tone |
|---|---|---|
| Orientation | Figure out if this is for him | Accessible and relatable, without jargon |
| Consideration | Compare and see the evidence | More specifically, with figures and examples |
| Decision | Confidence and a final push | Clear and confident, with a concrete next step |
Combine layers 1 and 2, and you’ll see just how intricate it becomes: a marketing manager in the exploration phase wants recognition and an overview; that same person in the decision-making phase wants evidence and certainty to justify the decision internally.
Layer 3: Tone of voice by market
Only once you have a clear understanding of your persona and stage does the language barrier come into play. A literal translation conveys the words but not the culture, and expectations vary greatly from market to market. This is especially important when expanding internationally: 76% of online shoppers prefer to shop in their own language (CSA Research).
| Market | What Works | What Turns Them Off |
|---|---|---|
| The Netherlands | Down-to-earth, direct, “you” | Exaggerated sales pitch |
| Germany | Thorough, formal, evidence, and figures | Too casual or too friendly |
| United Kingdom | Polite, with a touch of understatement | Intrusiveness |
| United States | Confident, results-oriented, clear CTA | Ambiguity and Modesty |
The same message therefore requires a different tone, structure, and amount of evidence for each market. But without the first two layers, even a perfectly translated text remains too general.
Tone of Voice in Practice: One Promise, Multiple Tones
Take one core promise—“a website that ranks well”—and see how it evolves when you combine the three layers:
- Growing entrepreneur, NL, focus: “A website that gets found and brings in customers. That’s how we do it—no fuss.”
- Marketing Manager, DE, comments: “Websites based on a proven approach and measurable results. Take a look at the numbers and the process.”
- Regular SME client, NL, objectives: “Keep your site up to date and easy to find, with a dedicated point of contact. We’ll take care of it.”
- International growth company, US, decision: “Ready for a website that drives real growth in every market? Let’s get started today.”
Same promise, four times right. That’s the difference between translating and connecting.
This is how we do it: one brand, two styles
At JKC, we deliberately write in a down-to-earth and direct style for the Dutch market, using “je” and “jij,” and we never start a sentence with “We.” For the U.S. market, we flip the switch: more confidence, more evidence and results, and a stronger call to action. Same services, same brand, different tone for each market. That’s not putting on a different face—it’s making sure the same message resonates wherever it lands.
Start with your reader: the questions you ask yourself
Before you write a single word, identify who you’re writing for and where that person stands. If you haven’t clearly defined your target audience yet, start by doing so. Be sure to answer these questions:
- Which persona am I addressing, and what does that person really want (results, proof, certainty, convenience)?
- At what stage of the customer journey is the customer: exploring, comparing, or choosing?
- For which country and which sector am I writing?
- How formally does this target audience address one another (using "je" or "u," first name or last name)?
- Are they expecting evidence and statistics, or mainly clarity and speed?
- What words do they actually use, and what jargon do they avoid?
- What factors influence their decisions: price, risk, quality, or speed?
Prompts You Can Use Right Away
AI excels at tailoring your tone to each person, stage, and market—provided you guide it properly. You can literally copy these prompts and fill in the blanks between the square brackets:
- Mapping the Market: “I write for [country] in the [sector] industry. Describe the tone-of-voice expectations: form of address (informal/formal), level of formality, how much evidence and data readers expect, and three pitfalls that cause this market to lose interest.”
- Adjust the tone for each persona: “My reader is [persona in one sentence: role, type of company, what they want]. Rewrite the paragraph below so that it speaks directly to this person: choose the right tone, the right evidence, and the words they actually use. Text: [paste text].”
- Variations by customer journey stage: “Provide three variations of this core promise: one for the awareness stage (accessible, relatable), one for the consideration stage (concrete, backed by evidence), and one for the decision stage (reassuring, with a clear next step). Promise: [insert promise].”
- Creating a tone-of-voice document: “I’m writing for this market and industry; this is my target audience. Based on the answers below, create a tone-of-voice document that includes keywords, forms of address, dos and don’ts, prohibited words, and example sentences for each stage of the customer journey. Answers: [paste answers].”
- Checking a text: “Evaluate this text against this tone-of-voice document. Where does it deviate, and how can I improve it sentence by sentence? Text: [paste text]. Document: [paste document].”
The Master Prompt: Your Tone-of-Voice Playbook in One Go
Would you rather have a complete playbook all at once instead of individual prompts? Copy the prompt below into your AI tool (ChatGPT, Claude, or another one), fill in the square brackets, and you’ll get a tone-of-voice document that you can apply and test right away.
You’re an experienced brand strategist and copywriter. Help me create a tone-of-voice playbook for my website. My company: [name + a one-sentence description of what you do] My markets: [e.g., the Netherlands, Germany] My key personas: [2–4 personas, each in one sentence: role, type of company, what they want] What sets me apart: [1–2 points] Example of my current text: [paste 1 paragraph] Deliver: 1. My brand voice in 3 keywords, with a brief explanation. 2. A table for each persona: what they want to hear, what tone resonates, which words to use/avoid, and what turns them off. 3. For each customer journey phase (awareness, consideration, decision), an example sentence for my most important persona. 4. For each market, the key considerations (form of address, formality, amount of evidence) + 3 pitfalls. 5. A list of “forbidden words” and dos & don’ts. 6. Finally, rewrite my sample text for [choose 1 persona] in the [choose 1 phase] phase, and explain in 2 sentences what you changed and why. First, ask up to 3 clarifying questions if anything is missing.
That last rule is important: by having the AI first ask what is unclear, you avoid a generic response. Save the result as a document (for example, an .md file) and use it as a benchmark for every new or translated page.
Would you rather not have to manually copy these prompts every time, but instead have your AI review your texts directly on your WordPress site and save them as drafts? You can do this by linking the AI to your site. You can read about how this works in “WordPress Management in 2026: Put AI to Work,” and learn about our perspective on the role of AI in our vision for AI.
From Answers to a Position Paper Using AI
Compile your answers into a short document, such as a Markdown file (.md), that outlines your tone for each persona, phase, and market. A strong document includes at least the following: the persona and market, the desired tone in three words, the form of address, dos and don’ts, forbidden words, and example sentences for each stage of the customer journey. This ensures that everyone creating content—whether human or AI—maintains the same tone, and you won’t have to explain it all over again every time.
Translation without context is just copying. With a tone-of-voice document, you translate the intended meaning, not just the words.
Translate Automatically Without Losing Your Tone
Manually applying your tone guide to every translated page is a lot of work. Translation software can help with that. Weglot, for example, automatically translates your WordPress site while taking your tone of voice into account: you provide the built-in AI with context for each language regarding how you want to sound, and you can always manually override automatic translations where needed. This way, you combine the speed of automatic translation with control over your brand voice.

Frequently Asked Questions About Tone of Voice
What exactly is "tone of voice"?
Tone of voice is the way your brand sounds: your choice of words, how direct or formal you are, your rhythm, and how much evidence you provide. It’s the personality behind your copy, regardless of what you say. That personality helps determine whether your target audience trusts you, and trust determines whether someone becomes a customer. The wrong tone will turn people off, no matter how accurate the content is.
Should I adjust my tone for each persona?
Yes, and that’s the level where most companies fall short. You maintain a single brand voice, but tailor the emphasis to each reader. An owner-manager wants results and simplicity without jargon; a marketing manager wants evidence and processes she can use to impress her team; a first-time customer wants accessibility and clear pricing; a loyal small-business customer wants warmth and reassurance. Same message, different emphasis and different words, tailored to what that person really wants to hear.
Why isn't translation enough for an international website?
A translation conveys the words, but not the culture or the expectations of a market. What sounds down-to-earth and pleasant in the Netherlands may come across as too friendly in Germany, while Americans, on the other hand, expect more confidence and a clear call to action. Moreover, even a perfect translation remains generic if you don’t tailor the tone to the persona and the stage of the customer journey. Translation is therefore the starting point, not the end goal: you’re translating the intent, not just the words.
How do I create a tone-of-voice document?
First, answer the questions about your persona, the customer journey stage, and the market. Use the prompts above to have AI convert those answers into a document that captures your brand voice in three keywords, the form of address, dos and don’ts, prohibited words, and example sentences for each customer journey stage. Save it as a short file (for example, an .md file) and then use it as a benchmark: paste a page and your document together into an AI tool and have it check the text. This ensures that everyone creating content—whether human or AI—maintains the same tone.
What is Weglot, and why do you call it that?
Weglot is translation software for WordPress that automatically translates your site while maintaining your tone of voice: you provide the built-in AI with context for each language on how you want to sound, and you can manually override any automatic translation where it needs refinement. This way, you combine the speed of automatic translation with control over your brand voice.
