A localization service is provided that provides users with online information on local retailers that sell particular products. A user can perform a search using a web page associated with the localization service or by searching using an internet search engine. The user's search includes a search origin. The search origin may be defined in terms of location information such as a place name or a postal code. A search for a particular product at local retailers may be made using search parameters such as search origins, product names, model numbers, product categories, and product attributes. The localization service may provide the user with search results in the form of web pages that list which retailers sell the desired product in the vicinity of the search origin. A targeted advertisement server at the localization service may use display criteria to determine which targeted advertisements should be displayed for the user.
