When it comes to affiliate marketing and promoting products or services, the main thing that is needed is you knowing what you are talking about. You don’t go to a car dealership to buy a car and the sales person does not what nothing about the car.
You don’t’ go to the barber shop to buy airline tickets. So the main thing that I what to say is that you do need to need the niche that you are in in order to sell anything in affiliate marketing.
Can I choosing a niche in affiliate marketing that I know nothing about?
Yes you can don’t it is worth it? yes you pick a niche to do affiliate marketing in without knowing nothing about the topic but how can you promote something that you don’t know? I would take some time a learn more about the niche that you are trying to promote.
What happened to me was that I picked something that I do not know much about and I didn’t really like the topic so it was hard for me to promote and overtime I started not to promote on more. I get bored with it and it was not something that I wanted to do. so the best thing that you can do is pick something that you know a lot about or wanted to learn. It’s hard to sell a keyword planner if you don’t know anything about keyword but you can learn.
