Titles are ranked by unadjusted revenue/base prices (i.e., for a book that is typically $10 and gets temporarily discounted, the full $10 gets counted towards its ranking nonetheless. Therefore, books that are typically $0 cannot influence the rankings). This ranking also includes pre-orders, which are charged ahead of time, effectively constituting a sale. Please note that Granblue Fantasy Volume 1 (usually $10.99) is temporarily receiving an 100% discount.
