Summary
MerchantWords sells access to a large database of Amazon shopper search phrases with search volume estimates, a keyword multiplier for related terms and a Page 1 view of top-ranking products. It is built for product sellers and PPC agencies; for a KDP publisher it can help brainstorm the seven backend keywords and Amazon Ads targets, but it is not specific to the Kindle Store or Books department and has no category, BSR or book sales data. Its ASIN Plus feature is US-only.
