Pinterest, as well as website traffic.

It's been nearly a decade since the fashion blogging phenomenon first kicked off, and after a great deal of blood, sweat, tears and ripped seams, fashion bloggers are now an accepted part of the fashion establishment, seen in the front rows of major fashion shows, landing prominent ad campaigns and starring on magazine covers. Some have even launched multimillion-dollar businesses and become household names.

• Followers and engagement on Instagram, Twitter, Facebook, YouTube and Pinterest, as well as website traffic. These numbers gave us a snapshot of how many people these bloggers are reaching every day. Some platforms, like Instagram, were weighted more heavily than others.
• Brand extensions. Bloggers were rewarded for launching their own lines and/or collaborations.
• "It" factor. We gave bonus points to bloggers who worked with higher-end brands and those whom industry insiders say are especially popular with advertisers right now.
• Google News searches. Generating headlines = influence.
