A branding guide is an invaluable marketing asset every business benefits from creating. This is the foundation of all other marketing and advertising to come. Without it, you risk eroding your brand over time as personnel and roles and responsibilities change. Team members without knowledge of the brand guidelines make recommendations that are not anchored to the same principals. A branding guide is the roadmap for graphic design, sales collateral, website development and all other relevant channels where you give your brand a voice.
