Lots of people who are new to the online business world have asked this question time and again: “What is a niche”? To answer that universal question, a niche is a well defined group of people who share the same needs, interests, and wants. For example, you have passion and expertise in the field of boats and boating. A good way to market online is to sell information about boating to boating enthusiasts. Although the target group of boating enthusiasts is a niche in itself, it is also helpful to break it down to smaller subcategories in order to get more satisfactory marketing results.
