Take advantage of marketing tools whenever possible. Many affiliate programs offer useful resources to their affiliates aimed at helping affiliates make more sales. These range from monthly newsletters highlighting upcoming sales, tips or affiliate case studies, Facebook Groups just for affiliates, private webinars explaining marketing strategies in depth and more. Ultimate Bundles does this exceptionally well.
The other things you want to pay attention to are these little icons. If you hover over them, they actually explain them. It basically shows the language, whether it’s one-time billing, recurring billing, or both, so if you see both icons it’s both; whether they have a $1 trial, which is a feature that not all products in Clickbank have, whether there is PitchPlus, which is basically an up-sell, and finally, whether or not they have basically a separate HopLink target URL, which is your affiliate link that can bring people to a mobile-optimized page. You can have your regular HopLink which will take people to the general sales page, or if they have this special one, it means they have a link that will go directly to a page that’s designed for mobile devices. This isn’t really crucial unless you have a lot of people that use mobile devices, plus more and more sales pages are responsive, so you don’t really have to worry about this.
I’ve had a quick look at your site and the first thing I noticed is that it’s not sexy. Site design is so important. Anytime I come across an ugly website I hit the back button faster than you can say call-to-action. I also see that you only have two pages, there’s no identity or branding behind the site. You’ve also got a generic header logo that is usually applied by default when you install a theme. No custom logo’s or anything.
