– Amazon ~ The Bookstore that Corrupted Hadleyburg
Sorry I don’t have the formula. But here’s the informed view:
negative review ratings don’t affect your ranking
the review ranking is a function of positive helpful votes, however
more value is given to unique IDs that review your reviews
i.e. if you simply have the same cabal ratings your stuff over and over again, you will not rank ask highly as a person with the same number of helpful votes all from different people.
