You can work around that by using javascript (checking for tab losing focus) and checking how quickly the links are being clicked. If you middle-click a bunch of links, then don't click any more links, then it can be inferred that one of the links that you clicked was "good".


How can that be inferred? Maybe the results were all bad and I'm refining my search query. Or trying a different search engine.


>Maybe the results were all bad and I'm refining my search query

that can be detected, by checking further searches are made using the same session.

>Or trying a different search engine.

Maybe if your audience is mainly HN users it might cause an issue, but I think most people don't bother with that so you can count it as noise.
