Finding the Niche
First of all you need to choose a market niche . A niche that must be of interest to you and possibly for which you have a minimum of expertise. If you have no expertise, no problem. Fortunately, skills can be acquired. Passions or interests, on the other hand, cannot.
Alternatively, if you have no interest or passion and your goal is only to generate passive income, you could look at niches related to trends or new services/products that have just come out on the market. For example, if you often how you can use this database effectively hear about a trend or a new product, it is possible that this is the right sector to dive into. Just like I did in a certain trending niche (which I will tell you about shortly). If you can't think of any trends, you can use the Google Trends tool to find the most searched terms at the moment.

Once you have chosen the niche in which to operate, you will have to start looking for money keywords that will allow you to generate passive income by promoting third-party products or services.
