The Google post then goes on to outline the different ways the search engine could have solved the “Bad to customers = Good for PageRank” problem, by either blocking or using sentiment analysis to pull sites with a lot of negative comments down in the rankings. Using sentiment analysis in search rank is tricky however, because it would also pull down sites about unpopular politicians and controversial issues like abortion.
Instead of using either of those two solutions to account for cases like the one described in the New York Times article, Google instead wrote an algorithm that can detect which hundreds of merchants (including DecorMyEyes) have provided “bad user experience” and algorithmically force them lower.
