Some Amazon Reviews Are Too Good to Be Believed

> They need to give customers a way to sort by review counts in a time-weighted fashion. In other words, a product with 1,000 reviews and a 4.5 average that had been sold for five years would rank higher than a product with 1,500 reviews and a 4.8 average that had been sold for three months. This would help identify the quality products from stable manufacturers.

Major improvements have been needed in Amazon's search ranking for years. The fact that it's little better than it was in 2002 tells me they don't really care to fix any of the issues with their shopping experience.

Dear anyone at Amazon: please read this and implement the suggestions: http://www.evanmiller.org/how-not-to-sort-by-average-rating....

Any ranking system you can suggest can and will be gamed and exploited. The problem is that Amazon is trying to rank products at all, not whatever opaque algorithm they are using to do the ranking. They need to turn off all the ranking and rating, and start actually vetting their suppliers, but that’s hard and expensive so they will never do it.

I agree they need to start actually vetting their suppliers. But I disagree with you about the ranking. "Sort by average ranking" is broken obviously brain dead ways. They need a transparent ranking system that correctly balances number of reviews with average rating. I don't want to user their actually opaque "relevance" ranking.
