Niche Market

I'm trying to seek a niche market that can make more money in internet.
Niche is a specific product or services that only need one information or knowledge, for instance I have a video that can teach people on how to promote their product or websites to get more traffic.

If the field of business is too general you will get less profit because many people have what you have. but a specific product or services will make you a millionaire atleast if 1,000,000 people bought one of your products.
