Clickbank is one of the most successful affiliate program in the internet, it has thousands of digital products that are easy to promote for huge commission. The main point with Clickbank is how to choose and promote a product that pays well.
To choose a good product in Clickbank, I would recommend to pick the product that pays %75 of the whole sale that should be about $35-$40 for every sell. Then you need to read and understand the whole sale page.
Then you can promote it through your blog or website. Some products in Clickbank provides you with graphic banners and photos. Then you can use those banners in your blog and websites.
Another way to promote the product is by submitting articles to high authority websites, something like Ezine Articles. You can also submit your articles to OGB blog and I guarantee you to see your article at the first result in Google after tow days. Don't forget to add a link to your website or landing page at the end of the article. You can also use PPC programs like Google Adwrods to send some targeted traffic to your landing page.
