Confirmation of Expectations Is Always a "Nice to Have"

I had always assumed this was a given but +Rand Fishkin conducted an experiment to see if the concept actually held water. The concept is logical, if more people in a period of time are finding a website valuable based upon ctrs that surpass average CTRs of that poistion then elevate the statistical outlying result higher in the SERPs because it has shown signals that it fulfills the users search query over the positions above it. Its amazing how logical it really is. If that CTR demand drops or search demand drops then reevaluate the position. If Google's product that it delivers to the market is quality search results, I think this concept makes perfect sense. When the users tell you something is valuable elevate it.....
