I was only slightly wrong. There *is* a link in their results - it's hidden and not obvious at first. So they can count clicks. But they also use that link to know WHO is clicking I am pretty certain of that now. Could you decode all the encrypted gubbins behind:
http://www.google.com/url?sa=t&ct=re...=http%3A%2F%2F
www.mesotheliomaresourceonline.com%

Nope - that'll be proprietary and very informative to Google. Anyway - I think this strengthens my theory that the more the links are clicked the better ranking you can get.
