Pretty Link Pro is the easiest affiliate link tracking plugin and link cloaking tool for WordPress. I use it on every site to make links look, pretty, and to monitor how successful they are. With options for automatic link replacement and a cloaking bar, it’s highly customisable!
Upgrading to the Pro version of Pretty Link enables the following options
– Auto keyword replacement
– Auto creation of pretty link for posts/pages and tweeting it
– Social sharing
– Turn your site into a link shortening service
– Import and export links
– Generate a Pretty Link Pro report
