Your brand has a marketing strategy with the tone of voice, but does anyone actually use it?

Most brands have one. Very few brands use it consistently, and their content gives it away.

A tone of voice document that lives in a Google Drive folder and gets opened once during onboarding isn't a brand asset. It's a formality, a tick box. And the result is content that sounds slightly different everywhere it appears, a formal LinkedIn caption here, a casual Instagram post there, a stilted email newsletter that reads like it was written by a different company entirely.

Audiences are more perceptive than brands give them credit for. Inconsistency in tone creates a subconscious friction, it makes your brand feel unreliable, even if no one can pinpoint exactly why. And in a landscape where trust is the deciding factor in most purchase decisions, that friction costs you.

Tone of voice isn't about being restrictive. It's about being recognisable. The brands with the strongest identities (the ones you'd know even without seeing the logo) have a voice that shows up the same way whether they're writing a product description, a complaint response, or a social caption.

If your tone of voice document exists, use it. Train your team on it. Make it a filter for every piece of content that goes out. And if it doesn't reflect who your brand actually is anymore, update it. Don't just leave it in a drawer gathering dust. 

Your voice is one of the few things your competitors genuinely cannot replicate. Protect it.
