SO, how do you know which side you’d fit nicely on? Think of this as a very basic (/basically not at all) Myers-Briggs-style overview of which path would suit you best.
If you’re full of ideas and eager to convey them, without having to worry about the pressure of making sure there’s an immediate direct result in return, brand marketing is best for you. Yes, your goal is to ensure your brand is growing (which you can find out via traffic increases, the opinion of panels etc.), but you more often get to utilise your creative mind, choose what you think would attract customers and put it out there for people to see. The success of brand marketing is more so in the eye of the beholder - subjectivity can make or break a brand-focussed ad, so you need to be able to positively target the mass market and make your work viral (for all the right reasons).
