So apps should have a sort of ELO ranking where they fight with apps in the same category (possibly multiple categories simultaneously) for dominance and the fight is implemented as which app gets bought when displayed to a user at the same time as another similar app?
- salmonellaeater 13y agoThe ELO ranking is more suited to explicit head-to-head matchups, but its statistical basis could be adapted to app rankings. You could basically collect statistics for each app position (#1 averages 1000 purchases/day, #2 averages 500, etc.) and then estimate the quality of each app based on how its purchase rate differs from the expected average for that position. Google and other advertisers face a similar problem with sorting ads, which suggests some other relevant inputs: http://en.wikipedia.org/wiki/Quality_Score http://en.wikipedia.org/wiki/Quality_Score
