Over the last 20 years, I have seen lots of training courses. I agree with most of your experts. Site Build It was the first good training course I took shortly after Ken Envoy launched it. I have gone the Affiliorama route and thought it was a good program for beginners. At the time I took the course, there weren’t many options for niches. I have heard good things about Chris Farrell’s program but personally have not taken it. Wealthy Affiliate is by far the best program. Members learn to build an online business regardless of the niche(s) they select. Wealthy Affiliate also has a very strong support system in place. The active community of members means people can get their questions answered quickly.
It can be published as a book, and other people have already suggested what to include into ‘part 2’. As someone who has been asked by other people wanting to promote my products/serviced, I’d love to read about the merchant’s side of AM, e.g. various software that can be used, how to choose affiliate partners, what to include in the agreement, etc.
Create a website about the topic that you have chosen. The key to succeeding with affiliate programs is to build a content-rich website with useful information built around a specific theme. Don't just lazily throw up a quick site or blog and string a bunch of affiliate links all over your pages. You have to start by building credibility, and the best way to do that is to write about something you know a lot about.
Affiliate marketing is often touted as a "get rich quick scheme" by shady sites offering pyramid schemes that promise quick cash for little effort. Make no mistake—successful affiliate marketers like Pat Flynn of Smart Passive Income put in a lot of effort toward building an audience and creating quality content that will bring in sustainable passive income. Expect to do a lot of legwork up front—but if you play your cards right, you can build a solid source of revenue over time.
