The marketing potential of Facebook and other social networks is incredible. You must always remember that social media is about engagement. Unlike billboards or newspaper ads, it involves a deeper level of interaction. It requires you to listen to your customer and communicate something more than a product and a price. It´s about building a relationship. Facebook isn´t a substitute for a website. You should always have your own website that is completely branded to your business with all your products and services available 24/7. Facebook, however, can be a very powerful supplement to your online marketing strategy.
