Hi, if you open your published hubs, you can see at the bottom before the 'comments' in line with Votes is the word 'SHARE'.
Choose LINK TO THIS PAGE
A pop up window will appear then copy the URL.
If you are making a new hub or editing one you can Link that URL on the hub.
When you click "link to this page" it will automatically generate your referral tracker.
~~correct me if im wrong,,thats what i understand your question.
