问题
What I am trying to do is track click throughs of individual users likes and shares. This is easy with a unique link or when using Like, using the ref parameter.
What I do now is show the like button on a certain page, with the ref parameter set so I track any click through's on that link.
But this has a problem or a bug, if you use ref and click the like button then ref will show up on the like post on fb and I can track this. BUT if you also leave a comment when you click the like button, then the link is shared but the ref parameter is not on that link anymore!!
Any suggestions on how to fix this?
