New York-based social media marketing software company Offerpop unveiled a new set of Facebook applications that were previously running in private beta with over 50 customers, including Case-mate, City Sports, and fashion brand Baby Phat.

Offerpop’s Facebook-specific applications include Tug of War, Photo Contest, and Exclusive, and they are all focused on users easily sharing content, commenting on a product, or sharing opinions through polls. These campaigns can be limited to fans only or accessible to all Facebook users. While with Tug of War users get to “choose sides” between two products, Exclusive is built around the “Like” feature in order to create fan-gated offers and content, and reward loyal customers.

Online shop Layla Grayce‘s Facebook page, for example, sets up a weekly poll through Tug of War to make fans choose between two products through commenting and sharing their opinions with their friends. “Weekly Tug of War campaigns are a great way to showcase our products, get customer feedback and engage in a fun, natural way with customers on Facebook,” says Wendy Estes, co-founder of Layla Grayce.

With Offerpop’s apps, users get to interact with brands using natural Facebook gestures such as liking and commenting, without having to grant access to third-party applications. God knows Facebook users are reticent about continuously giving away their information to new applications, so it seems that this kind of marketing campaign can only become more common. All the apps allow the page administrator to brand it themselves. Moreover, companies also get access to all the applications and may re-use them at any time for new campaigns.
