Your ranking is updated the first week of each month, usually around the 5th. Your store’s rank is determined by your overall gross sales compared to any other store that made a sale in that month. Any store that didn’t make a sale in the past month is not included in the ranking. The data contains gross sales made from the Marketplace, not earnings.
The ranking is calculated as a percentile. For example, if you are in the 80th percentile, that means that your store is selling more than 80% of TPT stores that have made at least one sale in the past month.
