Social Media Marketing and SEO 
LinkedIn.
Whether you're a marketing executive at a major company, a business owner who runs a small local shop or even a first-year college student looking for their first job after graduating, LinkedIn is for anybody and everybody who's interested in taking their professional life more seriously by looking for new opportunities to grow their careers and to connect with other professionals.
You can think of LinkedIn as the high-tech equivalent of going to a traditional networking event where you go and meet other professionals in person, talk a little bit about what you do, and exchange business cards. It's like one big virtual networking event.
Not only does it serve as a second company website of sorts, offering up information about what you do and why, but the LinkedIn Page is also a very functional and flexible marketing tool. Through consistent posting and audience engagement, you can build a centralized community on the world’s largest professional network and encourage employees to participate in spreading the word.
LinkedIn is distinct from other social platforms on the web due to its professional nature, which creates a sense of trust and credibility for your Page. As such, it’s no surprise that 80% of B2B social media leads come from LinkedIn.
