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.
In regards to affiliate marketing, click fraud most often refers to generating “fake” clicks to a merchant program that is based on a PPC compensation method. The fake clicks (which can be generated in a manual or automated fashion) have no chance of converting for the merchant since the traffic clicking the ads have no real interest in the product or service the merchant is selling.
Cost per mille requires only that the publisher make the advertising available on his or her website and display it to the page visitors in order to receive a commission. Pay per click requires one additional step in the conversion process to generate revenue for the publisher: A visitor must not only be made aware of the advertisement but must also click on the advertisement to visit the advertiser's website.
Ultimate Bundles is a trusted affiliate program paying affiliates 40% commission on sales (70% commission if you are a contributor). They put together a “bundle” of eProducts several times per year that focus on a particular niche. Ex. blogging, homemaking, healthy living, herbs & oils, working at home and more. These bundles usually cost just $20 to $40 but include thousands of dollars worth of products and bonuses. That's a great value your audience is sure to appreciate.
You should also make sure you aren't competing with your own affiliates for eyeballs. Any marketing channels you're using, such as search engines, content sites or e-mail lists, should be off limits to your affiliates. Put marketing restrictions into your affiliate agreement and notify partners immediately. It's your program--you set the rules. Or, if you prefer, you can let your affiliates run the majority of your internet marketing.
