A strong social media strategy

As I told you before, my research will focus on several brands that have a strong socialmedia strategy. In this post I want to show to you which brands I will analyze.
Social media-focused marketing firm Dachis Group has ranked the 15 brands that are doing the best job. Dachis tracked the real-time social activity—audience growth, engagement, advocacy, and "message propagation," the ability to get your news to spread around the web like wildfire—of 60 global apparel brands.
According to this chart ( http://fashionista.com/2013/07/exclusive-the-15-most-social-media-savvy-fashion-brands#2&awesm=~oCQitIiaNKilhp), I will observe:
