Kelly Clarkson Makes 'Strong' Social 50 Chart Debut
1000 No. 1s: Watch Kelly Clarkson Chat About Topping The Hot 100

With the release of Kelly Clarkson's latest album "Stronger" on Oct. 24, which debuted at No. 2 on the Billboard 200 this week, the singer also edges her way into Social 50 tally and debuts at No. 45.

In the days following "Stronger's" bow, she made appearances on sites like Idolator and CelebBuzz, where she named her favorite albums and answered various questions that pertained to her career successes.

Then on Oct. 27, she asked for fans to submit questions for her MTV interview. The next day, on Oct. 28, she notified fans that if they mentioned their favorite song from the album on GetGlue -- an entertainment-based social networking site -- they would gain access to a "Stronger" sticker.

Billboard's Social 50 chart ranks the most active artists on the world's leading social networking sites -- YouTube, Vevo, Facebook, Twitter, MySpace and iLike -- using a formula blending weekly additions of friends/fans/followers along with weekly artist page views and weekly song plays.

Aside from these few instances, though, no other attempts by Clarkson to engage with Facebook fans. That's odd, considering album releases are usually when Facebook pages burst with status updates. To be fair, she stayed rather active on Twitter through the week, which seems to be her go-to social network.

The other interesting thing to note is that Clarkson's video for the single "Mr. Know It All" premiered on Sept. 25 and had a successful run, pulling in 7 million Vevo plays so far. Yet, that fairly substantial momentum proved to be insufficient at bringing her into the top 50. Week-to-week, Clarkson grew her audience by 52,000 fans and also saw a jump in her plays, raising her Vevo play count up to 3 million.

The next eye-catching debut comes from dubstep act Nero at No. 48, who break into the tally thanks to iTunes making their song "Promises" off their latest album "Welcome to Reality" the free single of the week on Oct. 25. This assisted in boasting the amount of fans they gained week-to-week up to 12,200 and nudge their weekly play gain by 1 million. Over on the Heatseekers Albums chart, "Reality" re-enters at No. 28 with a 110% sales gain, according to Nielsen SoundScan.

Justin Timberlake continues his ascent up the Social 50 chart, charging 36-20. His latest movie "In Time" was released on Oct. 26 and in support of this effort, he's been keeping his Facebook page heavily updated with extra movie content, photos, and interviews. Since then, the singer-turned-mostly-actor made appearances on "The Late Show with David Letterman," NBC's "Today," "Late Night With Jimmy Fallon" and the cover of "Esquire" magazine, among others. This buzz helped Timberlake grow his audience by 162,000 fans and kept his near 3 million week-to-week.

Back in the top ten, Coldplay makes a nice 18-9 push, after the release of their latest album "Mylo Xyloto" debuted at No. 1 on the Billboard 200 and the group crossed the threshold of 15 million Facebook fans.

On Oct. 26, Coldplay performed in Madrid, as part of an American Express sponsored music series called Unstaged, which was simultaneously streamed live on YouTube and in New York City's Times Square. Week-to-week, this raised their Vevo plays from 6.2 million to 8 million.

As for the rest of the top ten, Justin Bieber (No. 1) and Adele (No. 2) hold down their respective positions while everyone else shifts a bit. Rihanna (4-3), Shakira (5-4), Lady Gaga (8-5), Katy Perry (9-8) and Pitbull (13-10) rise up the tally. Meanwhile, LMFAO (3-6) and Eminem (6-7) tumble.
