You should use that method if you cant use the JavaScript/Image/CSS methods. If you get the PHP class (link on the same page) you should use the method 'public function doTrackAction'. That method is used to track downloads and outbound links.

By using this method you basically have all flexibility to register whatever outbound link you want. In combination with campaign tracking (piwik_campaign and piwik_kwd parameters) it's very powerful.

Use http://dev.piwik.org/trac/wiki/API/Reference if the statistics reporting of Piwik is not sufficient. It is so flexible that I use that for a new toplist script I have written (for instance NaughtyCamToplist.com, based on LO and Piwik).

Hope you can figure it out.
