The Outranked Index
The Outranked Index measures how contested a market is, not how large it is. A category where one listing sits unchallenged at a high number scores low; a category where several listings trade the top spot scores high.
No completed period yet
The index is only computed for periods that have finished. The first reading publishes once a full week of marketplace activity has closed.
In the meantime, the market boards show what a top position costs in each category and country right now, and past issues are collected in the report archive.
