A niche is a specific corner of demand. It helps you focus on a clear audience, a clear problem, and a clearer way to stand out.
A broad topic like fitness or journaling is not usually enough. A niche is the smaller opportunity inside that broad topic, such as postpartum fitness, anxiety journals, or meal-prep videos for busy parents.
The narrower angle is what makes it easier to understand demand, competition, and what people actually want.
Beginners often struggle because they start too broad. A niche gives you a better chance to match real demand with a focused offer, whether that offer is a book, channel, product, or service.
It also makes content and SEO easier because your message becomes more relevant to the exact person you want to help.
