Abstract: A method and system for providing regional information based on location is disclosed. In accordance with the present invention, a user inputs a keyword, from which a target location and a search category are extracted. A location range for search is determined by setting a center of the location range to the target location. Search result data are retrieved from a search information database based on the search category and the location range. The location range may be increased or decreased in response to a user's request, based on which the search result data are updated. The apparatus and method of the present invention provides search results ranked within a certain geographical range from a target location, which makes it possible for a specific location-based business to advertise through an Internet search service in a cost-effective way.
