How Twitter Can Help Retailers Ring Up Holiday Sales

3. Increase sales and engagement with Twitter-specific offers. In addition to promoting existing holiday specials, create Twitter-specific deals that people can only learn about by following your brand on the social network. For example, cupcake bakery Sprinkles uses this tactic especially well. It posts phrases on its Twitter account that customers can whisper while in-store to get a discount. Not only does the discount drive more sales, but Sprinkles is able to directly attribute these sales to its Twitter efforts, thereby tracking its social return on investment.
