There are two approaches on niche selection: it's either you follow your interest or you follow the profits. Each approach to niche selection has its own advantages and disadvantages. Here are some tips that can help one in the selection of a niche: 1. First rule, make sure that a market exists and not merely audience. There is a wide difference between a market and audience. For instance, in a music equipment store some people are found to be standing outside the shop who seem to wait for a bus or their friends. They see those who are coming in and out the store. Can you refer them as markets? No, they are just audiences! The chances of buying a product is quite slim to these people. However, when someone comes inside the store and checks out the latest headset model, that's a market. Working with the market increases your chances of earning in some profits. 2. Know what the 'market' wants. It's not about what you want but what the market prefers. The more you get to know your market, the more you'd make a sale. 3. Match the 'purchasing capacity' of the market to the products promoted. If you are marketing to students then you sure don't wanna sell something these people can afford. Yes, they love viewing the pages but they won't buy no matter how they liked it because they just can't afford it.
