It is important that you first choose a niche and then select affiliate programs according to it.
Some 1-2 years back, when I also started affiliate marketing, I was applying for a lot of programs like an idiot and it was my mistake actually. If you apply for so many programs, you end up wasting time and getting confused.
So better start with a single affiliate program for now. Amazon can work good mostly for all niches
Start with Amazon Platform.
