Google is an Internet search engine giant that provides various kinds of search options like images, maps, etc. Local search is an option that provides the user with results about the place or geographical location associated with the query.
Google uses a structured database wherein searches can be geographically constrained. These local search results are determined by associating the query keywords to appropriate map locations in terms of postal address or even latitude and longitude.
The local search runs on an algorithm associating the query keywords appropriately to a map location and then optimizing the search result to provide reasonable results.
