I would have sworn up and down that Google organic listings operated without any integration of Google AdWords or AdSense data. Every engineer I’ve see talk about the subject has said as much and even the AdWords help documents stated this was the case. That was until now.

Will participation in AdWords or AdSense affect my listing in Google’s free search results?
Google’s advertising programs are independent of our search results. Search results display on the left side of our results page; ads appear on the right and in the colored box at the top.
