Facebook gives people the power to share and make the world more open and connected. Advertising on Facebook focuses on demand generation by enabling marketers to be part of the ongoing conversation and deliver relevant ad messages based on people's real interests and connections. Online marketers can reach a desirable, active audience of more than 400 million people on Facebook and precisely target their ads. Because people are on Facebook to discover and share information through the lens of their friends, it is an ideal setting for performance advertisers to generate new demand for their products and services.
