you don’t need the plugin to be setup on your sll site. you can add pretty links to any wordpress install and just use the redirect link in double agent. Prosper 202 needs its own domain or subdomain also. if you don’t have hosting other than your sll site you can try a third party link tracker like http://ww3.linktrackr.com

Instead of sending them straight to your landing page, redirect to a tracking link that can do split testing such as pretty links pro (that’s a wordpress plugin)
