MerchantWords publishes data based on searches from many of the major global marketplaces: United States Canada United Kingdom France Italy Germany and Spain. We are working on supporting a number of other countries such as the Australia Japan India and Mexico. If you would like to see more countries supported We visit pages on Amazon Jet and Walmart.com in the same way Google does to build their index. Doing this gives us a measure of the popularity of different search terms from their point of view. We also use search volume trend information from the major search engines. We analyze these two sets of data using our custom algorithm to estimate the number of bimonthly searches performed for each search term. This estimate is then published to our site. Today MerchantWords indexes search volume estimates for Amazon Walmart and Jet.com only. We are considering supporting eBay Etsy and Newegg.
