What You Need to Know
The lessons in this module tell you what a niche is (and what it isn't) and give you some concrete examples.
Your niche needs to be something you are passionate about, or at least interested in, so that you can write useful content about aspects of it. And don't worry, there are plenty of research tools that can help you with that.
But of equal importance is your ability to profit from that niche. Which means the existence of reputable vendors with quality products, who are running affiliate programs that you are able to join.
