NY’s FanGager Tracks Lady Gaga and Britney Spears’ Facebook Engagement

According to NY-based startup FanGager, Lady Gaga was the third most engaged page on Facebook in March. Britney Spears, who wasn’t even on the list in March, is now sitting at number nine due to the launch of her new album.

FanGager ranks sites not by how many fans they have, but by how many of these fans are active (those that ‘Like”, post comments, etc.). Currently, Justin Bieber is at number one with 359,116 active fans (he has over 20 million fans on Facebook).
