Writing product reviews are an excellent way to enhance your credibility as an affiliate marketer. This is especially easy with information products like e-books which are relatively inexpensive. After establishing some steady income it may even be worth buying higher-end products, provided you get in touch with the product creator to work out a strategic marketing plan that takes you to the next level.
In some instances — like when the affiliate link is embedded in your product review — a single disclosure may be adequate. When the review has a clear and conspicuous disclosure of your relationship and the reader can see both the review containing that disclosure and the link at the same time, readers have the information they need. You could say something like, "I get commissions for purchases made through links in this post." But if the product review containing the disclosure and the link are separated, readers may not make the connection."
The terms of an affiliate marketing program are set by the company wanting to advertise. Early on, companies were largely paying cost per click (traffic) or cost per mile (impressions) on banner advertisements. As the technology evolved, the focus turned to commissions on actual sales or qualified leads. The early affiliate marketing programs were vulnerable to fraud because clicks could be generated by software, as could impressions.

You could start off by doing a simple Google keyword search to find out how many people are searching for your niche of interest. Similarly, if your niche focuses on digital products, a great place to do research is on ClickBank, which is considered to be one of the largest affiliate networks online. The end goal is to find a profitable niche and run with it!
As a course developer and promoter, I can say that on the face of of it, promoting can be easier than developing one. The upside of development though, is that once it’s done, have to do is keep it updated and it can earn you money for years. That’s the case with my SEO copywriter training course, which I’ve been teaching (and earning from) since 2009.

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.
