Copy and design are two pillars in an overall marketing strategy. They are the most visible of all marketing aspects and construct the face and voice of the brand. Working together they create a brand that is unified in appearance and voice across all platforms. If one is lacking then the brand as a whole is missing a critical aspect and as a result is missing out on potential customers. Hiring someone who can create and carry out a synergistic approach to both is critical to the overall health of a brand.
