Selling one or more products within a niche can greatly enhance your ability to do well in this business. The key is that you will need to find a niche that is profitable but is not one of the largest ones. For example, let’s say that you were selling a product that everyone wants. The demand is super high and it sounds great. The problem is, when you go to sell it, there are few people that actually buy. What happened to that market sector that was so large? The problem here is that the group demand was there but so was the competition.
