I was recently offered a link from a site with a very high page rank which I am very excited about! However, they cannot hard code my link into the page, and said that they have to append tracking code to the link for their tracking purposes.
Will Google now think that this link is not natural because of the tracking code?
Also, does page rank flow through the link even if there is tracking code in it?
Why won't you use referer to determine where click comes from and maybe save it as a cookie so that all later transactions done will be clearly links to the site from which originally that visitor came from? In this case the link can be exactly the same without any build-in tracking.
