As opposed to traditional online advertising, which involves a lot of money, social media optimization, has literally marked the beginning of an era which involves free-of-cost online advertising and marketing. It integrates brands with social networking websites which offer extended visibility to the brands, inside their networks, free-of-cost. And then they enable their users to directly interact with brands. In the long run, this situation is definitely going to re-structure the field of PR and market communications as communicating to a “disperse crowd” is a huge difference from directly getting in touch with one’s customers.
