I don't have any Idea about Social Media Marketing anyone can help Me?

There are two basic strategies for engaging the social media as marketing tools:
Passive approach.
Active approach.

Social media can be a useful source of market information and a way to hear customer perspectives.

Social media can be used not only as public relations and direct marketing tools but also as communication channels targeting very specific audiences with social media influencers and social media personalities and as effective customer engagement tools.

social media websites can target niche markets even more precisely.

Google Adsense does this by looking for keywords in social media user's online posts and comments.

Social networks are, in many cases, viewed as a great tool for avoiding costly market research.

Facebook and LinkedIn are leading social media platforms where users can hyper-target their ads.

Social media use in a business or political context allows all consumers/citizens to express and share an opinion about a company's products, services or business practices, or a government's actions.

Social media marketing, it has become increasingly important to gain customer interest in products and services, which can eventually be translated into buying behavior.

Engagement in social media for the purpose of a social media strategy is divided into two parts. The first is proactive, regular posting of new online content and conversations, as well as the sharing of content and information from others via weblinks. The second part is reactive conversations with social media users responding to those who reach out to your social media profiles through commenting or messaging.

Social networking sites can have a large impact on the outcome of events.

Barack Obama, a virtually unknown Democratic candidate, utilized 15 different social media websites to form relationships with the millions of American citizens who utilize those networks.

In early 2012, Nike introduced its Make It Count social media campaign. The campaign kickoff began YouTubers Casey Neistat and Max Joseph launching a YouTube video, where they traveled 34,000 miles to visit 16 cities in 13 countries.

One of the main purposes of employing social media in marketing is as a communications tool that makes the companies accessible to those interested in their product and makes them visible to those who have no knowledge of their products.

These companies use social media to create buzz, and learn from and target customers.

It's the only form of marketing that can finger consumers at each and every stage of the consumer decision journey.
