A niche is a specific type of group that you specialize in helping.
The whole point of niching down is creating an authority to solve a very specific problem. I see a lot of people not getting that and niching down for no reason.
Good Niching Down: Creating Social Media AI Agents for Law Firms. Law firms will go for you because you specialize in their industry.
Bad Niching Down: Baking Recepies for 50+ Males: This is not a specialty. It's just restriction for restriction's sake.
What is your niche? Are you niching down to build authority or is there any other reason to do it?
