What is a niche market? It is simply a group of people with a common interest. Some examples are hobbies, problems, desires, needs and hundreds of others. People are interested in information to help solve their problems. First you will need to find large groups of people interested in the same thing. Think of ideas you want to research. Do not waste time and money marketing to people who have no interest in products or services. Only focus on groups of people already interested in your product or service.
