Don't be naïve! Today, using Social Media isn't just spending time in front on your computer in order to share in real time what's happening in your personal life, what you had for lunch, or how you feel today. Nowadays, Social Media channels such as Twitter and Facebook, and even Blogs, are powerful professional tools you can use to get attention from people and companies from all over the world.
How does it work?
According to Wikipedia, Social media uses Internet and web-based technologies to transform broadcast media monologues (one to many) into social media dialogues (many to many). In other words, you can use your contacts' networks to communicate about your business, like a snowball effect.
But it would be too easy getting all the benefits of Social Media without keeping them updated. The companies who get on board with social media early are the ones that will build their relationships and viral networks that will pay off. In fact, neglecting a social media page can cause more damage than good.
When done correctly, Social Media is complementary to any SEO services, with each tool having its own benefits.
How much does it cost?
This depends on what you would like to set up. Take a look at each Social Media tool for further information.
