Not every affiliate program will be right for you; if one isn’t working out, try another one. By continually testing different programs, you'll discover which convert the best and which earn you the most money! Of course, remember that patience pays off as well; most affiliate revenue builds up over time, so don’t jump ship just because you haven’t earned money in the first few months.
Last time when I joined the Amazon Affiliate, my account was terminated because I didn’t had a single sale in 150 days. That’s the policy but I have one question, suppose we made a sale in 150 days , will this policy continue for the next 150 days or our account will active lifetime? how can i make it? whats the tools required? give me some example or ideas to creat portfolion in affiliate.

The niche you select should fit into your previous knowledge and current interests, but also be small enough that you can compete in the space. ​
I wrote this complete guide to making money with affiliate marketing because it’s something I love doing and many of my fellow YouTubers continually asked for advice in masterminds. They wanted to know how I earned more in affiliate income than advertising most months during my income reports. Like me, they were inspired by people like Michelle who were making tens of thousands of dollars every month while only working 10 hours a week and traveling the world. They wanted to know how I got started and how I make money with affiliate marketing so this post is my answer.
