Vine is a mobile app that allows users to create and share 6-second looping video clips. To be successful on Vine, users should fill out their profile with relevant information, connect their Vine account to Twitter and Facebook to expand their audience, research popular hashtags and types of videos, and engage with other Vine users by liking, following, and commenting on videos. Brands can also use Vine for marketing purposes like announcing new products, demonstrating their products or services, sharing events and promotions, and introducing employees to build their brand and connect with customers.
