What is a niche?

This is one of the tips I usually get when I ask how do I earn in blogging. They would reply, "find a niche and blog about it". Ok, so what is a niche by the way?

A niche is a specialization or a specific category. It is something that we can focus on so that we can get visitors whom we are sure is looking for what our focus is. Let us say that our focus is on books, our visitors would be book lovers.

Let us go off line and think of how shops work. We have auto supply shops, electronics stores, computer rentals, bakeries, restaurants and even supermarkets. For example, an auto supply sells parts of vehicles and their targeted market is vehicle owners. Electronic stores sells electronics and I am sure you won't find someone looking for pastries in an electronic store. These are examples of what people call "niche markets". We can be sure that the visitors of these stores are interested in what the store is selling (think of targeted visitors).

In order to earn money from blogging, find a niche which you can focus on and blog about it. Do not stray away from you focus and put up relevant ads on that niche. Like for example, don't put up ads for dynamite fishing when you are blogging about having an aquarium. Instead put up ads about where to buy aquariums, acquiring fishes, cleaning the aquarium, and how to keep your fishes from dieing.

So in conclusion; "finding a niche and blog about it" is simply -> Build blogs that people will find useful <- (Quoted from Mr. Manuel Villoria)

Note: This is how I understand it through research of the word "niche". If anything I said is wrong or you don't agree, please feel free to enlighten me by posting a comment. Thank you.
