I have campaigns set up for both keyword buys and content bids together. Is there someway to track sales using a unique referring url?
Well, you'll need to track sales on your own, but here's how you can distinguish between search/content & the website driving the content:
1. Distribution: To see whether a click resulted from an ad on the content network or an ad on the search network, add '&type={ifsearch:search}{ifcontent:content}.' For each additional variable you would like to track, add a '&' instead of a '?'.
2. Site: If an ad is played on a content network, you can see the website that the ad was displayed on by adding '&site={placement}'
An example of a full URL that you would generate to pass this information through to your logs is listed below: www.widget.com/home?type={ifsearch:search}{ifcontent:content}&site={placement}
