Brafton has reported that nine in 10 Americans use social media sites each month, and a new eMarketer report suggests that Facebook reaches nine in 10 social network users. The research firm anticipates that Facebook will reach the majority of U.S. web users this year.

EMarketer expects 132.5 million online Americans to use Facebook this year. This represents a 13.4 percent increase over last year, when 116.8 million U.S. web users accessed the site.

If eMarketer's forecast is correct, Facebook will reach 89.6 percent of U.S. social network users this year. Moreover, it will offer marketers access to 57.1 percent of the U.S. online population.

The company expects Facebook's reach to continue to grow in the coming years. By 2012, the firm expects Facebook to reach 90.9 percent of social network users and 60 percent of U.S. web users. By 2013. Mark Zukcerberg's social site is expected to reach nearly two-thirds of all American internet users (62 percent).

With this in mind, marketers will want to plan camaigns to connect with consumers via the social site. One way to effectively engage Facebook users is providing them with custom, info-heavy content. As Brafton recently reported, repetitive content and overly “chatty” content are two of the leading factors that drive consumers away from brands on the social network.
