Set reasonable expectations for earnings. You've only invested $20. You're going to make 5 percent on most products. That means that you need to sell $400 worth of stuff to make back your investment. You get credit for purchases customers make while at Amazon besides just the product you linked to, so it's not as hard as it may sound. It won't make you rich, but it's not hard to be profitable, and the income builds over time.
Also probably worth noting that if you are thinking about signing up for the Amazon affiliate program and are located in Colorado or New York, sign up with an out of state business address. Amazon closed their programs to affiliates in these states because of tax laws that were passed. There are quite a few services that allow you to choose a business address in a different state and will automatically forward your mail to your current address.
My biggest frustration is how to drive my target to my site and links. I have to do YouTube videos as part of what I told the publisher I would do. I have cards in my YouTube videos to try to steer the traffic to my site where they can look at the offerings in a very organized fashion (which really is one of two places on the web that provide this for this publisher). I just want to work smarter instead of harder. I have had so many people thank me for the videos but it is not converting through the affiliate links. I can’t stop the YouTube videos because it is part of the agreement. Also posting the reviews on Amazon.com in the product reviews. I don’t think I can add a link to my site in product reviews.
