Stylophane, a specialist for search engine marketing, monitoring, and facebook marketing, has developed the Facebook Fashion Index, a tool to rank the top fashion retailers on facebook. The index tracks the official Facebook fans for over 1,000 fashion brands and updates the numbers daily around 3pm. You can also filter special brands or find out about special discounts, contests or new arrivals.

The Facebook Fashion Index is divided into the four categories Bronze (below 1,000 fans), Silver (1,000-10,000 fans), Gold (10,000-100,000 fans), and Platinum (over 100,000 fans). Brands that are usually in the top ten platinum range of the index are for example Adidas, Puma, Nike, Converse, Levi’s, Gucci, Lacoste, Burberry and Chanel, with having a fan base between 1.8 and 7.4 million.

There’s also a separate index for the category denim. Platinum brands that are in the top ten range are for example Levi’s, Diesel, and Guess. You can also click through brand profiles or compare the percentage change between the number of fans of today versus the last day of the previous month. All index brand names are hyperlinked directly to the brand facebook fan page.
