The techniques introduced here provide a method of gathering ecommerce data. The techniques described here allow a system to return information about a product from several non-related ecommerce sites in response to a single search query. Using the techniques described here, a data mining system determines from the search query a product ID and retrieves from a database one or more product links that correspond to the product ID. Using the product links retrieved from the database, the data mining system traverses the links and parses the web-pages corresponding each of the links to determine up to date product information. The product information can then be returned to the application that initiated the request.
