Well, there is a search engine that does that, but it's not Google. :-) Google ups the priority of a result based on the links to that page; see http://www.google.com/technology/ for more information. The links in Google's search results lead straight to the actual address of the page, without being redirected through Google first, so it has no means of keeping track of which links you visit. DirectHit, however, does what you're thinking of; see http://www.directhit.com/about/ for more information. The links in its search results are redirected through DirectHit, so that it can keep track of which are visited.
Aumentar!
Onward,
