  With what account? Google serves on a ton of third party sites (and not just through AdSense, DoubleClick is huge). And that would require you to sign in to Google before you are opted-out, regardless if you were using Google or not. I use an plugin provided by Google to do the same thing, no worries about a cookie disappearing. http://www.google.com/ads/preferences/html/intl/en/plugin/ http://www.google.com/ads/preferences/html/intl/en/plugin/
