Marketing, not just digital marketing, has definitely involved into a combination of art and science. And to be successful, you need inputs that come from two distinctly different kinds of people (brain types):
Marketing Technologists vs Marketing Creators
Marketing Creators. People who understand how to communicate, both visually and through the written/spoken word. These tend to be the right-brained “creative” types who understand color theory, appreciate white space, and intuitively understand how to communicate with the consumers you seek in meaningful ways that induce movement.
Equally as important is understanding how to get these two types of people to work together and respect the value each other bring to the table.
