Marla Erwin helped Whole Foods master social media.

Think you’re busy trying to constantly update your own Twitter page? Imagine handling more than a million Twitter followers.

Marla Erwin, Interactive Art Director for Whole Foods, is credited with Whole Foods’ social media success. In its first year on Twitter, Whole Foods gained a million followers. Since starting with Twitter, Whole Foods now has several separate accounts for users who have more specific questions about the store’s products — a Twitter account for cheese, one for Whole Foods recipes, etc.

How did Marla garner so many followers? She incorporated user-generated content onto Whole Foods’ Twitter and Facebook accounts. Recipes, product ratings and reviews and comments on the Whole Foods’ blog all went onto their Twitter feed.

Marla then went on to use Facebook and Twitter for different uses: Facebook she uses for more editorial content and to start discussions among fans and friends (since users can see others’ comments on Facebook, it’s easier to have a discussion), and Twitter she uses for Whole Foods promotions, information for customers, to answer customers’ questions and tweet out links to Whole Foods’ blog.
