Recently, there was a post questioning Amazon as one of the AdWords' search partners.
I used search partners long ago, and then stopped after seeing negative ROI for that part. The post I mentioned prompted me to test again. I have my own scripting that picks the referrer (website, search engine) and passes the info to the end reporting. Even though there was traffic from search partners in various geo-locations (worldwide, not US), I saw no sales. I thought that maybe something has changed so my script continued reporting Google as the originator while ads were served elsewhere. Then I figured I could insert Google's own tag which passes the variables like "g" or "s" for G or SP, respectively. I did, and so far I saw one sale only, from dp.g.doubleclick.net.
I was doubting into my scripting, but now, seeing those "g" tags only, is it really that bad?
Thanks
