The vocabulary of building a brand.
20 terms, each defined in a paragraph you could quote without the page around it, and each with the distinction people actually get wrong. Written to be useful to somebody who never buys anything.
Last reviewed 16 August 2026 by Saffi. Every definition re-read for accuracy against the shipped product, and each entry checked against the pruning rule. How we check.
Foundations
Brand persona
A structured description of the brand itself: who it is for, what it stands for, how it sounds, and the impression it intends to leave.
Read the definition →Brand consistency
Brand consistency is the degree to which every piece of work a brand produces reads as coming from the same source.
Read the definition →Brand archetype
A brand archetype is a stock character borrowed from narrative theory, such as the Sage, the Rebel or the Carer, used as shorthand for how a brand should behave.
Read the definition →Personal brand
The reputation a specific person holds in the minds of people who encounter their work: what they are known for, who they are useful to, and how they sound.
Read the definition →Brand positioning
The deliberate choice of what a brand stands for, for whom, and against which alternatives, expressed clearly enough that the choice excludes things.
Read the definition →Brand strategy
Brand strategy is the set of decisions that determine who a brand is for, what it claims, why that claim is credible and how it differs from the alternatives.
Read the definition →Voice
Brand voice
The consistent way a brand sounds in writing and speech: its vocabulary, sentence rhythm, level of formality, humour, and the things it refuses to say.
Read the definition →Tone of voice
Tone of voice is the situational adjustment a brand makes to its constant voice: warmer in a welcome, plainer in an apology, tighter in a status update.
Read the definition →Systems
Brand kit
The single place a brand's operating decisions are recorded: colour palette with usage rules, typeface pairing and scale, logo direction and clear space, written voice, and the strategy underneath them.
Read the definition →Brand drift
The accumulated distance between the brand a business decided on and the brand it is currently executing.
Read the definition →On-brand content
Published work that a familiar reader would attribute to its source with the logo removed.
Read the definition →Brand guidelines
A documented set of rules governing how a brand may be expressed: logo use and clear space, colour values and where each is permitted, typography and hierarchy, imagery treatment, voice principles, and the things explicitly not allowed.
Read the definition →Content pillar
A content pillar is a recurring theme that a person or brand returns to across their published work, chosen because it sits where their expertise, their audience's problems and their commercial interest overlap.
Read the definition →Style guide
A style guide is a written reference that fixes the repeatable choices in a body of work: spelling, capitalisation, punctuation, terminology, formatting and, in visual guides, the mechanics of using type, colour and imagery.
Read the definition →Brand system
A brand system is the connected set of decisions, rules and shared components that lets many separate outputs read as one brand.
Read the definition →Brand audit
A brand audit is a structured review of how a brand is currently being expressed, compared against how it was defined.
Read the definition →AI
Identity
Visual identity
Visual identity is the set of seen elements a brand uses to be recognised: logo and its variants, colour palette, typefaces, layout conventions, photographic treatment, and the rules governing how they combine.
Read the definition →Brand colour palette
A defined set of colours with fixed values and assigned jobs, not simply a set of swatches.
Read the definition →Brand typography
The typefaces a brand uses and the rules governing them: which faces, which weights, and a defined scale of sizes, line heights and spacing for each level of text.
Read the definition →When a definition is not enough
Several of these terms have a full essay behind them: what a brand kit actually is, brand drift and how to catch it, how to define your brand voice, and on-brand content, defined so you can test for it.
