Add a third, a fourth, or an entire team of contributors to a content management system, and the risk of a fragmented brand identity multiplies quickly. Different writers bring different instincts - one favours formal, measured prose; another writes with breezy informality; a third peppers every page with exclamation marks. Left unchecked, these tendencies quietly undermine the credibility and professionalism that a business has worked hard to build. The good news is that inconsistency is entirely preventable, provided the right structures are put in place.
Start with a "Tone of Voice" document
The single most valuable tool a business can create is a comprehensive tone of voice guide. This is not a vague list of adjectives ("we are friendly, professional, and innovative") but a practical, example-led document that shows writers exactly how the brand should sound in a wide range of situations - from a product description to an error message, from a press release to a social media caption.
A strong tone of voice document defines the vocabulary the business prefers and the vocabulary it avoids. It explains whether the brand uses contractions ("we're" rather than "we are"), whether it addresses the reader directly as "you", and how formal or relaxed the register should be. Crucially, it includes real before-and-after examples, because abstract principles are far easier to grasp when set alongside concrete illustrations. Writers should be able to pick up this document and, within an hour, have a clear mental model of what good looks like.
The document should also address how tone shifts in context. A business dealing with a customer complaint, for instance, needs to communicate very differently from one announcing a product launch. Capturing these nuances explicitly means contributors are not left to make judgement calls that quietly dilute the brand's identity.
Maintaining a consistent message across a team of contributors is not a question of controlling creativity - it is a question of providing clarity
Establish a clear editorial process
A tone of voice document is only useful if there is a process that ensures it is followed. For businesses where multiple people publish directly to a CMS, this typically means introducing some form of editorial oversight. Depending on the size of the team and the volume of content being produced, this might mean a dedicated editor who reviews all copy before it goes live, or it might mean a peer-review system in which contributors check each other's work against agreed standards.
Whatever the structure, the key is that no piece of content should move from draft to published without a second pair of eyes. Even experienced writers drift. They pick up new habits, mirror the language of whatever they have been reading lately, or simply have an off day. A light-touch editorial layer catches these inconsistencies before they reach the audience.
It is also worth setting clear standards around formatting and structure - not just tone. Decisions about heading styles, sentence length, use of subheadings, and the handling of technical terminology all contribute to how a brand feels. When these decisions are made ad hoc by individual contributors, the result is a website that reads as though it was assembled from several different sources, because effectively it was.
Invest in training
Many businesses hand a new contributor access to the CMS and point them vaguely in the direction of a style guide, then wonder why their content feels inconsistent. Effective onboarding treats tone of voice as a skill to be developed, not a document to be skimmed.
This means walking new contributors through the style guide in a structured way, ideally with examples drawn from the business's own content - both exemplary pieces and those that missed the mark. It means giving new writers a period of supervised publishing, where their work is reviewed and discussed before they are granted greater independence. And it means making feedback a normal, expected part of the process rather than something that happens only when a significant error has been made.
Training should not be a one-off exercise. The brand's voice may evolve as the business grows, enters new markets, or shifts its positioning. Regular team sessions - even brief ones - that revisit the tone of voice principles and discuss real examples help keep contributors aligned over time.
Use templates and structured content
For businesses producing high volumes of similar content - product descriptions, location pages, case studies - templates are a powerful tool for maintaining consistency. A well-designed template does not stifle creativity; it channels it. By defining the structure, the required components, and even suggested word counts for each section, a template reduces the number of decisions a contributor has to make and therefore the number of ways they can inadvertently diverge from the brand standard.
Within a CMS, this might mean building page templates that prompt contributors with specific fields rather than a single open text box. When a writer is asked to complete a "product benefit summary" rather than simply write freely about a product, the resulting content is more likely to feel coherent alongside everything else on the site.
Create a reference library
Beyond the tone of voice document, it is useful to build a shared resource that contributors can consult when specific questions arise. This might include a glossary of preferred terminology - particularly important in technical industries where the same concept might be described several different ways - as well as guidance on common dilemmas such as how to handle acronyms, when to capitalise job titles, and how to refer to the business itself.
This reference library should be easy to find, easy to search, and kept up to date. An outdated style guide is almost as problematic as no style guide at all, because contributors either ignore it or follow guidance that no longer reflects the business's current direction.
Audit content regularly
Even with strong processes in place, inconsistencies will emerge. Language evolves, teams change, and the cumulative effect of dozens of small decisions can shift a brand's voice gradually over time. A regular content audit - reviewing a sample of pages across the site against the tone of voice guide - helps identify drift before it becomes entrenched.
These audits are also an opportunity to update the tone of voice document itself. If contributors keep asking the same questions or making the same choices that feel slightly off-brand, that is a signal that the guidance needs to be clarified or expanded.
Maintaining a consistent message across a team of contributors is not a question of controlling creativity - it is a question of providing clarity. When writers know exactly what the brand sounds like, why it sounds that way, and how their work will be reviewed, they are better equipped to produce content that feels coherent and purposeful. The investment required to build these structures is modest compared with the reputational cost of a website that speaks with too many voices at once.
