You wrote a good 101 for people who would like to start an affiliate business online. Actually, you pointed a good way to start earning an income easily by purchasing an ebook or report with resell rights and then placing it on the online marketplace, so affiliates could sell. But I can tell that a lot of these resell rights (PLR) products are sold and then resold and then re-sold-sold even more, so the thing is that everybody sells them or offers as a ‘bonus gift’ for signing up for a newsletter. The best way to market a product online is to create your own unique product. It is not as hard as most people think, especially when you could outsource a lot of work… Only the quality and unique products which have great sales pages will get a lot of affiliate attention and promotion. While affiliate marketing concept sounds very easy, actually you need to put in some real work in order to be successful.
Just my 2 cents. Anyway, great post.
