You can earn quite a lot of money through the Amazon Associates program if you use the right tools effectively. Once you've found the right path for yourself you will see that it isn't really all that difficult to earn a reliable income through the program.
Product Reviews Give You Better Conversions: A main factor in getting more sales as an Amazon Associate is getting your CTR (Click Through Rate) to be as high as it can be. Perhaps the best way to accomplish this particular goal is to choose products that relate closely to your niche for review so that your reviews are easier to find and you are more likely to make sales. Try to remember that your reviews need to be well written and offer a good and clear picture to your readers. Your reviews need to be honest because it will help you get your readers' respect and trust. If you want to make sure that you have an honest and unbiased review, ask the product manufacturer for a demo unit so that you can see the product firsthand; this will help your review be more effective.
Put Product Links in Your Content: The type of blog you have doesn't matter as much as the niche on which you focus; plenty of money is available when you put product links inside of your content. Plain text links that are weaved inside the text of your blog post can get you a large number of clicks to your product, clicks that actually convert into sales. Visitors are lots more likely to trust a link in the body of a blog post than they are a blatant advertisement. It works more like a recommendation rather than an ad.
Rotate Your Specials: Static Amazon banners might bring in a modicum of income but the real way to make sales is to regularly swap out the products that you are featuring on your site so that they have more opportunities to buy from you. You can use Carousel widget banner ads for this purpose, which are interactive and typically display five to ten products through a rotating banner. If you'd like to get as many results as possible then you should focus on combining dynamic and static ads--this creates a neat and easy carousel of Amazon banners that link straight to your Associates account. Once you have the widget's code in hand, you can easily post it at your website or blog.
There are a lot of Amazon Associates who make tons of money while on autopilot but they are only able to do so because they put in lots of time and effort when they got started and built good foundations and strategies and that is what you will need to do as well.
