Advertising and marketing have always been huge open-ended questions for businesses: what portion of my money used on marketing is actually allocated effectively? What advertisements are/will really reach my intended target market? Unfortunately, the success of a marketing campaign in its totality isn’t usually directly measurable. As social networking begins to evolve and become more commonplace, entrepreneurs are becoming more and more convinced of its effectiveness and necessity—both in personal and professional spheres. The most important part of the new marketing: it’s free. It’s a guaranteed way of reaching millions of people with the click of a button. It allows prospective clients to interact with the business before entering into a formal relationship. Companies are then able to gauge what exactly people are looking for as their interactions through these sites express their interest.
