Not to sure about clickbank. One thing that you can do to increase "click" is to hide the urls in your site. This is done using htaccess. For example for a dating produt the clickbank link would show:
hxxp:www dot thisguyisgonnagetsomemoneyfromyouWatchOut dot com
By using Htaccess you can hide that affiliate link. So the new URL would show
hxxp:www dot (your site name)/dating product.
This will also help to prevent your affiliate links from being stolen.
This is what I use in the htaccess file.
Redirect /yahoopersonals
hxxp://(your affiliate link here)
Is it a cure all for all your woes. Prolly not but it is a start. Good luck dude!
