Why is this information helpful to you? This is one of the few ways that authors, agents, and publishers can simultaneously see how a publisher's best books stack up against their peers. For example, Neilsen BookScan doesn't let other publishers see the competition's sales numbers (only bestseller lists). But, WildFire's free research gives ECPA publishers a way to see which titles are selling well on Amazon at 14 other houses. This data is also helpful to see which authors, topics, and genres are dominating Amazon sales trends.
