In addition, if you choose to display prices for any Product on your Site in any “comparison” format (including through the use of any price-comparison tool or engine) together with prices for the same or similar products offered through any web site or other means other than an Amazon Site, you must display both the lowest “new” price and, if we provide it to you, the lowest “used” price at which the Product is available on the Amazon Site.
I`ve had only negative experiences with clickbank. I`ve only ever sold one 33 dollar digital product. The kicker is that about 5 weeks later, it got refunded! Quality really is a big issue with these products as you said. Thanks for finally explaining “gravity.” Now I`ve got a great way to judge what is quality and what isn`t. One question thought, does gravity take into account refund rates?
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
