Ideally, there should be a feature that lets you see the personalized (that is, real) search results of others. Maybe divided into target groups ("programmers", "male users under 20", etc.). Of course, everyone's real search results will be slightly different, incorporating "+1"s of Google+ friends for example.

But, I assume, the bulk of the search ranks will be the same for people in the same (advertising) target group. (I have nothing to back up that assumption - it just would be the most sensible thing to do, I think.)
