When we are talking about social media marketing first the meaning of social media should be very clear. Social media is an instrument of communication through which all the social things are discussed. Media is a way of communication and the social media is a medium of communication for all the social related things.  Social media marketing refers to the process of gaining traffic or attention through social media sites. Social media itself is a catch-all term for sites that may provide radically different social actions. 

For instance, Twitter is a social site designed to let people share short messages or “updates” with others and you can share your views or can have a debate and put your point of view in front of others, whereas Face book is in contrast is a full-blown social networking site that allows for sharing updates, photos, joining events and a variety of other activities Face book connects people who know each other and also helps people to make new friends and have fun with them it is a great web site to interact with new people and reconnect with the old once. Thus social media marketing should be done so that more and more people can know about it and access it.
Social media marketing has emerged in recent years as a popular way for independent businesses to promote themselves without the need to spend a lot of money. Unlike traditional marketing methods, social media marketing is less about selling and more about building relationships with customers so that they’ll be more willing to deal with you. These relationships are particularly important for small businesses since winning the trust of leads is vital to converting them to customers.

Social media marketing is the process of marketing through social media sites. By utilizing the social aspect of the web, social media marketing is able to connect and interact on a much more personalized and dynamic level than through traditional marketing. Fortunately, these people self-identify themselves by the searches they make on Google, Bing and other search engines. If your site appears on the first page of the results they receive, you will get a high number of visitors who want and need what you sell.

Social media marketing programs usually center on efforts to create content that attracts attention and encourages readers to share it with their social networks. A corporate message spreads from user to user and presumably resonates because it appears to come from a trusted, third-party source, as opposed to the brand or company itself.[citation needed] Hence, this form of marketing is driven by word-of-mouth, meaning it results in earned media rather than paid media.
