2 define your niche
Before you an define your niche, you'll need to understand wtf is a niche? Here's a brief definition courtesy of the dictionary:
noun, a comfortable or suitable position in life or employment.
adjective, denoting or relating to products, services, or interests that appeal to a small, specialized section of the population.
Niching down your brand will help you define who you will connect with and how your brand can best serve that specific group. For example, my niche is not conservative, stay at home mothers who like to bake. You can probably see how that might be an odd fit for my brand. I curse, I don'y discuss food and I don't touch on anything child related. I focus on creative women who are building outside-of-the-box lifestyles and businesses. I need my brand to connect with these women.
