The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you. 
Indicate who is the main contact for the account. Select the first bubble, labeled “the payee listed above,” to indicate that you are setting the account up for yourself. Select the second bubble, labeled “someone else…,” if you are setting the account up as a representative of a company. Click “next: your website profile” to finish setting up your Associates account.[4]
If you would like to take a more subtle approach, include a product or service from your company that relates into your blog post. For example, let’s say that you are a wine connoisseur and that is what your blog is based around. In any post that is enticing your readers to open up a good bottle of Merlot or what have you, it would be wise to embed an ad for a quality, easy-to-use wine opener, wine glasses or stoppers that keep the wine fresh.
But beyond these specific points, promoting affiliate products on Amazon really involves the same ground rules that apply to affiliate marketing in any form or on any other site or network. That is, know the products you’re promoting, be honest in how you represent those products, and give people enough information to make an informed decision about the product.
Great post , I do read a lot of the Nichehacks articles and this one is so true. At the moment I am in a niche I'm passionate about and yes although I am primarily using Amazon to monetize my site, I will be branching out to use other methods very soon. It frightens me to think the plug can be pulled at any time! I intent to use other affiliate programs as well as Amazon, maybe Google Adsense, I'm not sure yet, some digital products and also to build an email list.
Ah, my favourite section. SO, by now, you guys should know that I hate crappy advice. Wellll, I feel like the Internet really let me down with affiliate marketing, because there’s so many small considerations and details that people rarely mention in the beginner guides. SO, here are some sad truths to be wary of (that I had to learn the hard way):
The Amazon Associates affiliate program uses a tiered commission structure to pay out to affiliates. The more you sell, the more you will earn. That’s why many affiliates will attempt to promote two different types of products – cheap and expensive. By promoting cheap products under $10, you will likely receive a lot of purchases. For example, many affiliate marketers will promote e-books that may only cost $5. Since Amazon only pays up to 8.5% commissions, you’re not going to earn much by selling a $5 e-book. However, making a lot of sales of smaller items helps to boost your sales count in the, which also boosts the amount of commission you receive. Here is the current Amazon Associates Affiliate Program commission structure:
If you create a product or service then affiliate marketing can be used to generate buzz and ensure a successful launch. Successful affiliate products stand the test of time and business ideas span across several industries and verticals. It is also highly effective at generating leads, trials, and sales. Since you only pay commission after a genuine sale is made, there’s a minimal amount of risk involved. Once you set up your program and find affiliates, it’s a relatively self-sustaining channel that basically manages itself. This frees you up to pursue new marketing initiatives or focus on other areas of your business.
One thing you should strongly consider is promoting digital information products. These products are attractive for two reasons. First, they have higher conversion rates because the customers can get instant access and instant gratification when they purchase. Second, they typically offer much higher commission rates than physical products -- which means more profits for you.

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.
