how to detect quality? define quality! which kind of user wants/needs quality at all? and in which situation? quality can be difficult to comprehend at times. all the more if you're in a hurry. bad navigation forces longer visits, rubbish articles on crappy web pages take more time to scan. doesn't adsense contradict on-page quality? complete information given, no need to click an ad. quality valuers don't like to click ads. and so on and so on..
what's relatively clear to me, is that only a human - a sophisticated and educated one - can define and determine real quality. not with clicktrough behavior, but with common sense. google is lost there. algos lack media competence. just like most humans.
