Let's assume that the Facebook era includes 2007 - Current.
Then during the Facebook era, two things happened:
- Victoria's Secret leads the "Facebook Likes" category.
- Victoria's Secret squeezed out a compound annual sales increase of 3.6%, barely better than inflation (see page 9 of the appendix in this report from Limited Brands).
Also be careful when reviewing the marketing literature of the attribution community. These folks will link sales to social media, and yet, as we see here, there's not much to look at in terms of sales and Facebook Likes.
