It is no longer an option for businesses to ignore social media platforms. Each platform has a unique audience of users, and with each audience you may get different levels of engagement - so don't assume that failing to reach one audience means you'll fail to reach any audience on social. We use several social media platforms at Tribute Media. They are all used for different reasons and they all have their own culture while still maintaining our brand. The trick to using it successfully is to know who your target audience is and how they are using each platform.
Pinterest is a stand-alone visual social network built around engaging visual content. Users share images from the web by “pinning” them on to a series of virtual boards. These images then (when clicked on) lead to a web page away from Pinterest. That's where it becomes beneficial for your company. If you can catch a lead from Pinterest through an image, title, and short description - you've got the opportunity to direct them to your website.
