I have, over nine years of consulting work with mid-market marketing functions, read something like 210 brand-voice documents. Each one has been written by a smart and thoughtful marketing team, working with a smart and thoughtful brand consultancy, to describe the specific voice a specific brand wants to be known by. Each one has been, individually, competent. Read in aggregate, they are describing, with slight variations, the same voice.
This is not, in the strict sense, a criticism of any individual brand-voice document. Each one, taken alone, is defensible. The aggregate pattern, however, is a strategic problem — a specific one — and the pattern is worth naming because it produces marketing functions across the industry that sound identically like each other while believing themselves to sound distinctively like themselves.
The uniform voice
The specific voice that most brand-voice documents describe, on close aggregate reading, has a specific set of characteristics. It is warm. It is honest. It is human. It is confident but not arrogant. It is knowledgeable but not condescending. It is friendly but not overly familiar. It uses everyday language and avoids jargon. It has a sense of humour but does not force it. It talks to the customer rather than at them. It is inclusive.
You have read this description before, in some order, across dozens of brand-voice documents. So has everyone else in the industry. It has become the default brand voice, produced almost automatically whenever a marketing team commissions the voice work.
Every brand cannot, by definition, have this voice. The voice, as described, is not distinctive; it is a description of a specific set of communicative virtues that any competent brand ought to aspire to. To say that a brand's voice is "warm and honest and human" is to say roughly nothing about how the brand distinctively sounds. It is a description of a floor rather than a ceiling — the base level of communicative decency any brand should meet before starting to think about its actual voice.
How the uniformity gets produced
The specific mechanism producing the uniform voice is worth understanding, because understanding it points at how to escape it.
The first driver is that the brand-voice documents are, in most cases, produced by consultancies whose methodology has been optimised across many client engagements. The methodology's optimisation, over years of iteration, has converged on a specific vocabulary and a specific set of framing devices that produce documents clients accept without excessive revision. The consultancies, in their own commercial interest, produce documents that pass client review reliably. Passing client review reliably means using vocabulary and framing that no client will find objectionable. What no client will find objectionable is, almost by definition, what nobody in the industry can distinctively claim.
The second driver is that the brand-voice work is, in most cases, done in isolation from the specific content the voice will be used to produce. The consultancy sits in workshops with the marketing team, discusses the brand's values and character, and produces a document. The document then arrives at a marketing team that has to produce specific pieces of content — a specific email, a specific landing page, a specific social post — against the document's guidance. In this process, the specific abstractions the document contains are translated, by many different writers across many different pieces of content, into whatever those writers were going to write anyway, plus a light adjustment toward the document's language. The document, in effect, does not actually change how the marketing function writes.
The third driver, and the most consequential, is that most brand-voice documents describe the voice the brand aspires to have rather than the specific voice the brand actually can have. The aspiration is, in almost every case, a version of the uniform voice — because the uniform voice describes a set of virtues everyone aspires to. The specific voice the brand can actually have — given its specific product, specific customer base, specific team, specific founder personality, and specific historical positioning — is much narrower and, in almost every case, meaningfully different from the aspirational voice the document describes.
Why this is a strategic problem
The uniform brand voice produces, on aggregate across the industry, a specific commercial disadvantage that is hard to see in any individual brand but is visible when you compare brand recognition across categories.
The specific mechanism is that brand voice is one of the primary vehicles through which brands become recognisable to audiences over multi-year windows. A brand with a distinctive voice becomes, over time, identifiable in the wild — audiences can tell that a specific piece of communication is from a specific brand even without seeing the logo. A brand with the uniform voice is, structurally, unable to achieve this recognisability. It reads as competent and thoughtful and warm, but so does every other brand, and the audience cannot distinguish them by voice alone.
The commercial cost of unrecognisability is substantial and mostly invisible. Brands whose voice is distinctive accumulate audience recognition faster than brands whose voice is uniform. Brands with strong voice recognition can, on brand-tracking data, sustain premium pricing more effectively, retain customers at higher rates, and produce marketing investment that compounds across years. Brands whose voice is uniform must, in effect, re-establish themselves in every piece of communication, because the audience cannot carry recognition across pieces.
The uniform brand voice is the most common single strategic failure I see in mid-market marketing. It is easy to produce, difficult to detect, and expensive to sustain. Fixing it requires acknowledging that the voice work done to date, however competent, has produced a competitive disadvantage.
How to escape the uniformity
Three specific practical steps, in order of feasibility.
The first is to test your existing brand-voice document against the uniformity trap directly. Take three pieces of your brand's recent marketing content — an email, a landing page, a social post. Remove the brand's name and logo. Show the pieces to five marketing professionals unconnected to your business. Ask them to guess which brand produced the content. If the guesses are, in aggregate, wrong or if the professionals cannot narrow the field to a small set of possibilities, your voice is functioning as the uniform voice. This is a diagnostic that most brands do not run and that almost every brand should.
The second is to identify the specific characteristics your brand's voice has that would not appear in the uniform-voice description. This is harder than it sounds. Most marketing teams, asked what makes their brand voice distinctive, will produce a list of the same uniform-voice virtues. The specific work is to identify the characteristics your voice has that are, at the same level of abstraction, not aspirational virtues but specific stylistic choices. Does your brand use specific rhetorical structures other brands do not? Does it engage with specific subject matter that other brands avoid? Does it have a specific rhythm, sentence length, punctuation practice that differs from the industry norm? These specifics are where distinctive voice actually lives.
The third is to commit to holding the specific distinctive voice against pressure to conform. Marketing teams and their agencies will, in the natural course of production, tend to smooth voice back toward the uniform. Every piece of content produced will have a small tendency to move toward what feels safe and universally acceptable. Over time, this tendency accumulates until the voice is again uniform. The specific commitment required is to review output against the distinctive voice periodically and to actively reintroduce the distinctive characteristics when they have been smoothed away. This is, in practice, one of the highest-leverage pieces of strategic marketing work available in any function that does it well. Most functions do not do it, because the smoothing is invisible and the maintenance is unfashionable.
The distinctive voice, on the data I have seen, produces recognition, produces recognition-driven commercial advantages, and produces marketing programmes that compound across years in ways the uniform voice structurally cannot. The specific work required to escape the uniformity is small, unglamorous, and reliably productive. The industry's failure to do it, at scale, is one of the most consequential unfinished strategic tasks in mid-market marketing.
