Is there a search engine that rates websites by measure of external ... trackers? Don't know how to word that ;)

You know, when you have noScript (or whatever) installed and are glad to see that, say, the average xkcd comic does not show up with even one external .js or whatever to load...

edit: I obviously want a search engine that shows hits with less trackers on top... ;)

edit2: Sorry as this might not actually be related to Linux directly, but I couldn't think of a better sub.
