How Facebook Makes $$$$$$$$$

While most industry insiders have a firm grasp on Facebook’s monetization models, most people still don’t understand how Facebook makes money. For those that still don’t know how Facebook makes money, we thought we’d take the opportunity to break down Facebook’s various revenue streams including past and future streams of revenue. After reading this guide, you should have a complete understanding of how Facebook makes money.

Advertising Business
Facebook’s single most important revenue channel is advertising. The company has always been ad supported and most likely will always be ad supported. While some have claimed that Facebook will one day charge for access to the site, those rumors are completely false. Facebook generates over half a billion in revenue each year, the vast majority of which comes from advertising. So who is paying for advertising?

Self-Serve Facebook Advertising
The largest chunk of Facebook’s advertising revenue is the company’s self-serve advertising platform. By visiting the following page you can set up your own advertising campaign on Facebook. These advertisements are displayed in the sidebar of most pages of the site. That includes user profiles, events, groups, Facebook Pages, and third-party applications. The primary advantage of Facebook’s self-serve advertising platform is the granular targeting features.

Over the past few years Facebook has increased their targeting capabilities, including the ability to limit advertising to metropolitan areas as well as the following target variables: gender, age, network (workplace, school, etc), profile keywords, relationship status, and more. Facebook recently released the Facebook Ads API which provides large ad buyers with the ability to build robust ad managers on top of the Facebook advertising platform.

We’ve written about a number of companies who have built services on top of Facebook’s Ads API. To boil it down, the Facebook Ads API enables Facebook to reduce the amount of friction large advertisers (those who spend more than $10,000 a day) have in posting new advertisements and modify existing ones. According to numerous sources, Zynga, the developer behind the largest games on Facebook (FarmVille, Café World, etc), is the largest purchaser of Facebook’s self-serve ads.

Small businesses like doctors, lawyers, restaurants, and others are also responsible for a large amount of Facebook’s revenue generated by the self-serve advertising platform.

We expect Facebook to generate somewhere in the range of $450 million this year (2010) on self-serve ads (allfacebook.com)
