What is the Best Type of Niche?
A niche where people are likely to make only one purchase is fine, but only if you can generate the volume to support it. To make more money it is better to find a niche where people will buy the same thing repeatedly, or buy related products.
For example, a friend of mine collects sports cards. As a collector, he is not going to buy a few cards and then stop. This is a niche where people will buy the same thing over and over. On top of that, some of the cards may be very special, creating a need for special display binders. Proper storage is important for the other cards as well. But he also needs to know how much the cards are worth, and try to get an idea of ??their future value. Of course, to do this he has to be informed about the players on each card which leads to the purchasing of reference guides and sometimes a subscription to a few sports and / or collector's magazines. So, not only have established a niche where people keep buying the same things (sports cards), but it is also a niche market where people are likely to buy related products.
Catering to those niches that continually spend money is part of what will keep people coming back to your site for what you offer. But there is one more thing to consider to get people to return to your site. You need to show people that you know something about the niche if you want to be recognized as an authority that people can trust enough to potentially buy from. That is one reason why when you are starting out that choosing a niche you are interested in will help.
Once you have found a suitable niche, try to branch out from it, but in a logical way. Think about the related products or services your current niche may also like. Check out competitor sites to see if they offer related products. Visit and read online forums related to your niche. There will often be discussions that point out ways you could logically add to your offers.
Marketing to a niche where customers make one or two large purchases may be okay with you, and can put a large sum of money in your bank account, but only sporadically. Each payment may be bigger, but you will have to work harder to keep bringing new people in to buy from you. By finding a niche market that spends a bit here, a little there, and needs another thing, then something else to go with it, you may get smaller amounts, but in volume. While you will still want to seek out new customers, you will be generating income from current customers at the same time.
