Social media marketing (SMM) takes advantage of social networking to help a company increase brand exposure and broaden customer reach. The goal is usually to create content compelling enough that users will share it with their social networks.
One of the key components of SMM is social media optimization (SMO). Like search engine optimization (SEO), SMO is a strategy for drawing new and unique visitors to a website. SMO can be done two ways: by adding social media links to content such as RSS feeds and sharing buttons, or by promoting activity through social media via status updates, tweets, or blog posts.
