These two things are very important considering the situation. But I think marketing is more important. There is no doubt that the more branded a product is, the more valuable it will be. But marketing dominates the brand, because unless people are familiar with your product, how will they know about the brand?The terms Branding and Marketing are fundamentally almost the same, which makes it precarious to recognize the contrast between them. The thing is, regardless of how indistinguishable they appear, when you investigate, are a ton of contrasts going on.
As I would see it, I think they are both Important and they structure together to make a synergy.
Branding and Marketing work hand close by, to expand your ubiquity. Branding is your message, your motivation, it is the thing that keeps clients returning for your services/products again and again. While Marketing brings you new crowd that is keen on your items/products.
Branding can't occur without Marketing, since, how might individuals become acquainted with your image on the off chance that you don't Market/Promote it? Also, Marketing can't occur without Branding, since you can't Market a brand with no reason by any stretch of the imagination.
