USAToday: Next time you become of a fan of a favorite musician on Facebook, you may be helping them inch their way up a chart. Billboard’s new Social 50 recogizes the online popularity of celebs on social networking sites, with Rihanna coming out on top of the chart’s debut week, reports USA TODAY’s Cindy Clark.
To come up with the rankings, a formula takes into account weekly additions of friends/fans/followers along with weekly artist page views and weekly song plays on MySpace, YouTube, Facebook, Twitter and iLike — but friends/fans behavior takes precedence, followed by artist page views and song plays. The final ranking also includes a unique metric measuring the ratio of page views to fans. Rounding out the top five this week is Justin Bieber, Eminem, Lady Gaga and Nicki Minaj. The chart will appear on Billboard.com and Billboard.biz every Thursday, and in Billboard magazine every week.
