I currently have a bunch of campaigns running and they are doing ok. But I am looking to track which keywords are converting from the sponsor sites. Currently I tracking the keywords fine from google on my side. No problems there. But when I push the user to the sponsor site the url is something like this going to the sponsor as the referer http://www.example.com/landingpage.html?keyword=widgets once it hits the sponsor the referal from the sponsor is being displayed as http://www.example.com/landingpage.html, Ive contacted them and they are of no help anyone going through the same thing or have any ideas on how to get around this.
you can try hypertracker. it allows you a half-way solution, i.e. if the visitor clicks on a link/button located on your page that takes him directly to the order page of your sponsor,it will call it a conversion. if you get a good product presentation on your site and convince user to buy it will work in ~80% for you.
