I am finding clickbank to be less and less realible these days and have noticed that 50% of clicks are not even being accounted for. I now use a very simple tool that counts clicks through your hoplinks. Its very easy to set-up and use and I would suggest everyone who owns a site to start using it. This is the tool Click Counter Make sure you change the password and other settings in the settings.php file. After uploading it, you should go to the admin panel, start a new link by pasting in your hoplink, it will then give you a new link which you will use in its place. Every click is then tracked, its also a very easy way of just changing a hoplink within in a couple of seconds without having to change any links on your site. I have been using it recently and found that 50% of hoplinks are not accounted for.
