If your plan is to build an entirely online business and to make money either directly from a blog, or perhaps by selling digital products, then the first thing you need to do is to choose a ‘niche’.
The term niche in this context essentially refers to a subject matter, an industry and an audience. In other words, a niche can be ‘health’ or it can be ‘knitting’. This is what your blog is going to be about, it is what the products you sell should be about and it will determine precisely who your business is marketed at.
Choosing your niche is one of the most important steps in creating a successful online business and the reason for this is that it will directly impact the amount of competition as well as the size of your audience. If your subject is ‘health’ then you’re going to be going up against millions of other websites and this is going to make your life very difficult indeed.
