If you’re the vendor, then you create your own product and set it up using Clickbank’s system. They then list your product in their marketplace so that tens of thousands of affiliates can see you. They handle the tracking using unique tracking links and cookies so they know exactly where the sale came from and credit the referring account accordingly.
When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
You can put up banners on your site, to promote your affiliate offers. Most affiliate programs will usually provide their own creatives when you sign up for their offers. All you have to do is insert the banner on a highly trafficked page (your affiliate tracking is usually embedded within the code). Banner ads in the right locations can do a great job of driving sales.
It is important to note, however, that StudioPress is now a subsidiary of WPEngine which is the company that actually does the web hosting on which StudioPress’s Genesis framework runs. The affiliate program only works with choosing the StudioPress framework and themes, not the actual hosting on WPEngine. WPEngine has a separate affiliate program for its hosting services, which yes, is a bit confusing.
Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.
