Lot's of interesting data and some findings I didn't expected. Thanks. What I have missed in this paper is the impact of customer reviews (a 4.5 ranking has a higher uplift potential than a 5.0 star ranking - according to some studies). And the number of reviews has impact as well. Not enough studies around for a meta analysis?
