Depending on your business, you could set goals the following way for a Linkedin campaign:
You could measure the power of the links to your account by the links that the linking account has. The more network it is attached to, the better it is for your business.
As for the quality of the links, you would want people related to your business linked to your account, rather than just random links. Over time you could create a metric based on how many contacts are built up through a contact (linking because of a link) or sales because of a contact (buying after accessing from your linkedin account).
