“Friendly, modern, expert.” This is how brands often describe their Tone of Voice — and this is where the problem begins. The characteristics themselves may be correct, but they provide very little guidance to someone who actually needs to write a real piece of copy. Can we joke when responding to a negative comment? Do we address customers formally or informally? Is it appropriate to use English terms? How do we communicate a mistake without sounding either like a cold corporation or an overly familiar friend?
A good Tone of Voice answers exactly these kinds of questions. It is not a decorative section of a brand book, but a system of decisions that allows different people to speak on behalf of one company in a recognizable and appropriate way. It applies not only to posts, but also to comments, Direct Messages, advertising, email, support, review responses, job listings, and even short error messages.
The term is sometimes transliterated into other languages, but throughout this article we will use the professional form Tone of Voice or the abbreviation ToV.
Tone of Voice is a system of principles that defines how a brand expresses its personality through words: what vocabulary it uses, how formally it speaks, how it explains, jokes, sells, and responds in different situations.
In other words, it is not only about the writing style of social media posts. The same voice appears on the website, in advertising, social media, emails, push notifications, chats, support, and other customer touchpoints. If a brand sounds simple and warm on Instagram but its support responses read like letters from a government institution, the problem goes beyond copywriting.
Tone of Voice helps make communication consistent, but consistency does not mean sameness. This leads to an important distinction.
Brand voice and tone are often used as synonyms, although it is useful to separate them in practical work.
Brand voice is the brand’s relatively stable personality. For example, a brand may be competent, direct, human, and calm.
Tone is how that personality sounds in a specific situation.
A new product launch may sound more energetic, a response to a complaint calmer, a technical outage notice more restrained, and a topical post more playful. The brand does not become a different company every time.
The practical formula is simple:
Voice remains recognizable. Tone adapts to the context.
For example, a brand that uses irony in regular posts does not have to joke with someone who has lost money or received poor service. Its voice can remain direct and human, while its tone naturally becomes more serious in that situation.
One of the most practical functions of ToV is to make the company’s voice independent of a specific author. Today, a post may be written by an SMM specialist, tomorrow by a copywriter, and the day after that an urgent response may be written by the business owner. Without shared rules, one brand can easily start sounding like three different companies.
A well-defined Tone of Voice should be documented, transferable, and reproducible by different people. Saying “our SMM specialist just writes really well” may be a compliment to the person, but it is a risk for the brand: if that person leaves the team, the established style may leave with them.
The second benefit is speed. A proper guideline reduces repeated discussions about whether a joke is appropriate, whether English terms are acceptable, how the audience should be addressed, which emoji can be used, and how direct a response may be. Tone of Voice is therefore not only a branding tool, but also an operational tool for the content team.
It is especially important in situations where improvisation is risky: complaints, delays, mistakes, conflicts, or reputation crises. A brand’s real voice is often revealed not in a polished advertising post, but in how the company behaves when something goes wrong.
Most brands would like to be friendly, modern, and professional. These adjectives therefore do little to differentiate a brand and, more importantly, do not provide the team with actual instructions.
Each characteristic needs to be translated into specific language behavior.
Instead of “friendly,” for example, you can define the rule as: we use simple language, address people directly, explain without sounding condescending, but do not become overly familiar.
Instead of “expert”: we explain the reasons, use specific examples, separate facts from assumptions, and do not hide a simple idea behind complex terminology.
Instead of “confident,” it is better to define the boundary immediately. “This approach will not solve the problem — here is why” sounds confident. “We know the only correct solution” is already categorical.
This is how a characteristic turns from a description into a working rule.
Starting the search for ToV with the question “Are we a fun or serious brand?” is too early. First, you need to understand the brand itself and the environment in which it communicates.
It is important not simply to identify the category — digital agency, clinic, SaaS, or retailer — but to understand the brand’s role in its relationship with the customer. Does it want to be an expert, partner, practitioner, mentor, or innovator? Or perhaps a brand that deliberately asks uncomfortable questions and challenges the usual approach?
The role affects communication. A partner explains things differently from a mentor, while a provocative brand can allow itself a different level of directness than a service whose main value is a sense of safety.
Tone of Voice cannot be defined through demographics alone. It is important to understand what people already know about the product, what language they use within the category, how much explanation they need, what irritates them, and what level of distance from the company feels comfortable.
For example, a performance marketer does not need CTR explained every time. A small business owner who is only beginning to work with advertising may benefit from a short explanation.
The audience helps determine how complex the brand’s language can be, whether professional English terms sound natural, and which form of address is appropriate.
The Tone of Voice of a fashion brand, bank, clinic, and bar is not developed according to identical rules. Different categories have different boundaries for humor, slang, provocation, categorical statements, and advertising claims.
A medical brand can absolutely be warm and human, but that does not make jokes about a patient’s fear or guarantees of results appropriate. Likewise, a financial service can use simple language without sacrificing accuracy.
Tone of Voice does not override ethics, professional requirements, or compliance.
After that, you can select several core characteristics. In practice, 3–5 clear principles are more useful than fifteen adjectives that no one remembers.
For each characteristic, answer three questions:
what it means; how it sounds; how it definitely does not sound.
This is the transition from brand personality to a practical Tone of Voice.
At the beginning, a simple matrix with several scales can help: more formal or informal, serious or playful, restrained or emotional, distant or close, expert or highly accessible.
This is not a personality test or an attempt to calculate the company’s character mathematically. The matrix is there to help the team agree on boundaries. For example, a brand may be approachable but not overly familiar; witty but not sarcastic toward customers; expert but not academic.
These kinds of clarifications later prevent dozens of subjective edits.
A young audience does not automatically mean informal address. Likewise, an older or B2B audience does not force a brand to become maximally formal.
The decision depends on the category, company culture, market, and expected level of distance. Even younger people may naturally expect formal address from a doctor, bank, or legal service while being perfectly comfortable with informal communication from a fashion brand or music app.
What matters more is that the chosen principle is clear to the entire team and used consistently rather than changing according to the author’s mood.
A guideline should not simply say “we use English terms.” It should define which words sound natural to the audience, which ones should be avoided, and when a term needs explanation. The same applies to professional jargon: it can make communication more precise for an expert audience but turn a simple idea into a barrier for someone outside the professional bubble.
Slang requires even more caution. If a particular expression becomes popular on TikTok, that does not mean the brand needs to start using it immediately. A more useful question is: does this sound natural for our personality, or are we simply trying to look younger?
Emoji work in a similar way. The question is not whether they are “professional,” but which symbols, in what quantity, and in which channels fit the brand’s style. Even a company that actively uses emoji in Stories may avoid them completely in crisis communication.
Punctuation matters as well. “Hi!” and “Hello.” create different levels of distance before we even read the next sentence. CAPS, dashes, short sentence rhythm, exclamation marks, and lowercase writing also shape how the brand voice feels.
“Our brand is fun, so we joke” is a weak rule. It is much more useful to define what kind of humor feels natural and where its boundaries are.
For example, a brand may use self-irony, jokes about professional situations, and light cultural observations, but avoid making the customer, their mistake, appearance, tragedy, or a discriminatory topic the object of the joke.
Every company will have its own list. The purpose is not to ban humor, but to avoid making the team discover the boundary only after an unsuccessful post has already been published.
Consistency does not mean that Instagram, LinkedIn, email, and customer support should sound identical word for word. One voice naturally adapts to the conditions of each channel.
A post may include more context, arguments, and storytelling. Stories require shorter, faster language. Comments naturally become less formal. LinkedIn may be slightly more structured, while support should be more precise and calm.
The main question is not “Do we write exactly the same way everywhere?” but “Does the same company still feel recognizable behind all of these texts?”
This is especially important in Direct Messages and support. If someone comes with a real problem, support should not be forced to joke simply because humor is part of the SMM style.
This is where the difference between voice and tone becomes most visible. If a brand is witty in regular posts, it does not mean that a response to a serious complaint should also be witty.
The voice can remain direct, clear, and human, while the tone changes — becoming calmer, more serious, and more attentive to the situation.
A Tone of Voice guide should include at least basic crisis communication rules: who responds, when humor is turned off completely, which promises should not be made, which topics require escalation, and when a response must be approved by management or the legal team.
It is better to have these rules before a crisis occurs.
One of the most persistent misconceptions is that a B2B company should communicate as formally as possible. In reality, B2B can also be simple, human, and witty.
The difference lies elsewhere. B2B often involves a more complex product, a longer sales cycle, several decision-makers, and a greater need for evidence. Expertise, accuracy, and specificity may therefore matter more than entertainment.
The problem begins when “professionalism” turns a normal idea into a long piece of corporate copy that is difficult to understand even for a client from the relevant industry.
A brand does not need to invent a personality that has never existed before at any cost. The fact that dozens of companies describe themselves as friendly, expert, or modern is not a problem in itself.
Uniqueness comes from a combination of details: vocabulary, rhythm, humor, examples, level of directness, topics, brand position, and boundaries.
The task is therefore not to find a “unique adjective,” but to consistently express the brand’s own personality across hundreds of real interactions.
Suppose a service will be unavailable for 30 minutes because of scheduled maintenance.
More formal:
On October 14, from 02:00 to 02:30, the service will be temporarily unavailable due to scheduled maintenance.
Friendlier:
We’ll take a 30-minute maintenance break tonight to help keep the service running more reliably.
More playful:
Night-time check-up: at 02:00, the service will take a short break and should be back in around 30 minutes.
The information remains the same. The distance, rhythm, and emotional tone change. Examples like these teach the team much more effectively than an abstract statement such as “we are modern and open.”
A good guideline does not need to be the longest document in the company. Its purpose is to provide enough specificity for a copywriter, SMM specialist, or support team member to make decisions without constantly guessing.
A practical document should include:
Brand personality. What role does the brand play in its relationship with the customer, and what is its core personality?
Audience. Their level of knowledge, expectations, language, and comfortable level of distance.
Several voice principles. Not a long catalogue of characteristics, but a small set of clear rules.
An explanation of each principle. What does “direct,” for example, mean specifically for this brand, and where does directness become rudeness?
Do / Don’t. Real examples of preferred and undesirable wording.
Vocabulary. Preferred words, constructions to avoid, English terms, and terminology.
Forms of address. Formal or informal address, level of closeness, and ways of addressing people.
Punctuation and emoji. Only the rules that genuinely help preserve the style.
Humor. What kind is appropriate and where it is definitely not.
Channel adaptation. How the voice is expressed on Instagram, LinkedIn, email, support, and other important channels.
Difficult situations. Negative feedback, mistakes, delays, crises, and escalation.
Real examples. Before/after fragments and several typical scenarios.
The best test of such a document is simple: after reading it, a person should understand whether a particular sentence sounds like this brand.
Compare these two responses.
Do:
“We checked the issue. It is on our side, and we are fixing it.”
Don’t:
“We’re sorry you feel that way.”
In the first case, the brand directly acknowledges the situation and takes responsibility. In the second, it formally expresses sympathy but effectively reframes the problem as the customer’s subjective perception.
An example like this explains in a few seconds what the brand means by directness and a human approach. That is why Do / Don’t should be one of the central parts of a guideline.
ToV answers the question of how to speak, but it does not determine what to talk about. Topics, content categories, content objectives, and the role of different formats belong to content strategy and the content plan.
A new Tone of Voice will therefore not save SMM if the company does not understand which topics the audience needs or what function its content should perform.
At the same time, even a strong content strategy can easily fall apart without a shared voice: every content category may begin to sound like a different brand.
UGC should not turn into a corporate press release, otherwise it loses its main advantage — naturalness. But that does not mean there should be no rules at all. A brand can define acceptable claims, correct product naming, topics to avoid, and boundaries for humor, especially when working with paid UGC creators.
Tone of Voice becomes even more important in Community Management. Comments, Direct Messages, discussions, reactions to UGC, and responses to negative feedback are often written quickly, without several rounds of editing. If the brand voice has not been defined, this is usually where communication becomes inconsistent first.
AI reproduces a style well only when it receives specific rules. A prompt such as “write a friendly post in our Tone of Voice” says almost nothing about what the brand actually considers friendly.
It is much more useful to provide the model with the brand personality, vocabulary, preferred sentence length and rhythm, Do / Don’t examples, examples of actual copy, wording to avoid, humor rules, and taboo topics. In practice, a proper Tone of Voice guideline can become a permanent part of the instructions used for AI-assisted writing.
However, AI does not remove the need for editing. Even a well-defined voice does not guarantee that a model will correctly assess the emotional context of a complaint, legal risk, or whether a joke is appropriate. Final responsibility remains with the team.
The test “we like how our posts sound now” is too subjective. It is more useful to evaluate what has changed in the communication system itself.
First, consistency: does the brand remain recognizable in texts written by different authors and across different channels? Second, recognition: is a distinctive style developing that can be differentiated from neutral corporate writing? Third, efficiency: has it become easier for the team to write, edit, and approve materials?
Audience response can also be considered, but carefully. If engagement increased after changing the Tone of Voice, that does not prove causality: topics, formats, distribution, or posting frequency may also have changed at the same time.
That is why the sign of a good ToV is not one marketing metric, but a combination of consistency, reproducibility, and contextual appropriateness.
Tone of Voice should not change every month, but it is not a “set it once and forget it” document either. A review may be needed after repositioning, entering a new market, changing the audience or product, merging brands, or simply accumulating enough practical experience to reveal weaknesses in the old rules.
At the same time, a single social media trend is not a sufficient reason to change the voice. If a new expression becomes popular on TikTok, that does not mean the brand should immediately start using it.
A more useful question is: is this a natural development of our personality, or are we trying to dress the brand in someone else’s style?
Problems most often begin with an overly abstract guideline. The brand defines itself with three adjectives but does not explain how they should influence actual wording. The opposite extreme is copying the style of a well-known company simply because the team likes it, without considering the brand’s own positioning and audience.
It is equally risky when the voice effectively belongs to one SMM specialist rather than the brand; all channels are forced to sound identical; there are no separate rules for support and negative feedback; humor is used even in inappropriate situations; and slang is added only to make the brand appear younger.
The opposite problem is also common: “expertise” turns into complex language that demonstrates the brand’s knowledge instead of helping the reader understand the topic.
Finally, even a good document is useless if it is created once, saved to Google Drive, and never used again. ToV should be part of onboarding, production, editing, Community Management, and AI-assisted writing.
The process can be reduced to several sequential steps: first define the positioning and the brand’s role, then describe the audience and the category context. Next, choose several voice characteristics and translate each one into specific language rules.
After that, add Do / Don’t examples, vocabulary, forms of address, humor boundaries, and difficult situations, and only then adapt the rules to different channels. The finished guideline should be tested on real posts, comments, support messages, and crisis scenarios — this is where it quickly becomes clear where the theory still lacks specificity.
The final step is to teach the team how to use the document and gradually expand it with real examples. Tone of Voice becomes stronger not when the guideline becomes longer, but when fewer communication decisions have to be made by guesswork.
A good Tone of Voice is not a description of a brand’s personality, but a system of decisions. It allows different people across different channels to speak on behalf of one company while keeping the voice recognizable and the tone appropriate to each situation.
That is why a strong guideline answers more than the question “What are we like?” It explains how the brand sells, jokes, explains complex topics, admits mistakes, responds to criticism, and changes its tone when the situation requires it.
If, after reading the document, a copywriter still has to guess “How would our brand say this?”, the guideline is not yet fulfilling its main function.
Tone of Voice is a set of rules that defines how a brand speaks and writes: what vocabulary it uses, how formally it communicates, how it explains, jokes, sells, and responds to different situations.
Literally, it means “tone of voice.” In marketing, the term usually refers to the tone or communication style of a brand.
Brand voice is the brand’s relatively stable personality. Tone is how that personality is expressed in a specific situation. Voice remains recognizable, while tone may become more serious, warmer, or more energetic depending on the context.
It helps maintain consistent communication, create and approve content more quickly, transfer work between different authors, and reduce improvisation in difficult situations.
There is no fixed catalogue of types. A brand may be more formal or conversational, serious or playful, emotional or restrained. It is more important to define specific rules than to choose a label.
Start with positioning, audience, and category context. Then select several voice characteristics and translate each one into specific language behavior and Do / Don’t rules.
Document the brand personality, audience, voice characteristics, vocabulary, forms of address, humor, emoji, punctuation, rules for different channels and difficult situations, and real examples.
There is no strict rule. In practice, a small number of well-defined principles is more useful than a long list of abstract characteristics.
Voice is usually relatively stable, while tone adapts to the situation. The guideline itself can also be reviewed when the brand, product, audience, or market changes significantly.
No. Communication can adapt to the characteristics of each channel. The important thing is that the same recognizable brand personality remains behind the different forms of presentation.
Yes, if it feels natural for the brand and its audience. Slang should not be added simply because a particular word happens to be trending.
It depends on the brand and the channel. A guideline can define which emoji are acceptable, how many to use, and situations where they are inappropriate.
Give AI more than the abstract instruction “write in a friendly way.” Provide the brand personality, vocabulary, sentence rhythm, Do / Don’t rules, examples, words to avoid, humor rules, and taboo topics.
Check whether the brand sounds recognizable across different channels and in texts written by different people, whether the team finds it easier to create and approve materials, and whether the guideline genuinely helps make decisions rather than remaining a formal document.
