Hey jcm, lemme try to help u with this...
First Go To:
My account --> URL trackers -->
There'll be a default tracker, which you may use. But it looks weird to me, so i suggest that you click the "create new tracker" which you can name as you wish. (keep a short word).
So once you're done with that, you're ready. Suppose, you made a tracker named "Facebook". Now, do exactly like this,
Insert in the URL to the page you want your visitors to go.
Eg: Im using one of your own link.
http://hubpages.com/ _facebook /hub/How-to-Reject-Romantic-Rejection
See?.... you just have to insert an "underscore" followed by the tracker. here, it is "facebook".(don't use any space inbetween)
DONE!!... now you are ready to go... its easy as that.
Feel free to ask if its not clear. You may also see the "help" in that tracker page for this info.
Happy to help,
