Note: I think the line where readers will push back probably will vary from blog to blog depending upon their readership. For example here on ProBlogger I get a little more negative feedback from readers on affiliate promotions. I suspect ProBlogger readers are a little more tuned into the issue and suspicious of some of the affiliate marketing that goes on around the web.
They tell you that the first step in the process is to choose a niche. In my opinion, this should be pretty easy for you determine before you even decide to get started. If not, then internet marketing may not be for you. The reason I say this is due to the amount of effort required to build a profitable business from scratch. If you can’t think of one single thing that excites or interests you, then you are going to have an uphill struggle if you plan to make a go of it in affiliate marketing.
