Actually Nunya, Jafar’s English is very good, with only a few very minor errors, and far better than most English speakers. It is simply not true that you can “barely read it”, it’s as good as yours. Most Americans, Australians and British I see online have very poor spelling and grammar, and use memorized abbreviations and SMS-speak instead wherever possible. You cannot sound as if you have something to teach people, if it sounds as if you still have to learn basic literacy yourself!
A large percentage of people starting an affiliate marketing business choose to market and sell information products, loosely defined as information packed in a specific format (e.g. text, audio, video, etc.) and meant to be sold and delivered to end customers. The best example of information being sold today is the highly lucrative “How To” category that can be found everywhere, literally in any niche in existence.
For example, if I talk about how cool a product is, and then you find out that I’m an affiliate for them, wouldn’t you as a conscientious observer become skeptical as to whether my information is biased, if perhaps I’m only saying how cool something is because I can get paid for it? Wouldn’t that make you question my integrity with other things I say as well?
