This document discusses the increasing importance of location data on the internet. As the web evolves from a network of documents to a network of people, location and geographic context are becoming central to how people use and interact with information online. The document outlines how local search queries are growing rapidly, and how location-based advertising and apps are driving this trend. It also introduces several Yahoo! technologies and data sources that can help websites better understand location, including GeoPlanet for place data and WOEIDs, and APIs for geocoding, place-finding, and more. Location data is transforming the internet as everything from search to social becomes more place-based.
