On March 1st, Google implemented a new, unified privacy policy that affects the browsing history and information Google has on you, both past and present. Prior to this change, your Google history of the searches you made and sites you visited was not shared with Google’s other services, particularly advertisers. Naturally, Google is one of the biggest media and marketing companies in the world, and your preferences and search information is pure gold from a marketing standpoint. Marketers armed with that information would know exactly what products and services to display to you as you use the search engine.
