Social Media Marketing (SMM) is one form of internet marketing that utilizes social networking websites as a relation building tool. The goal of SMM is to produce content that users will like and share within their social network to help a company increase its brand presence and broaden customer reach.
One of the key components of SMM is Social Media Optimization (SMO). Like Search Engine Optimization (SEO), SMO is a strategy for attracting new and unique visitors to a website. SMO can be done two ways: adding Social Media links to content, such as RSS feeds and sharing buttons -- or promoting activity through Social Media by updating statuses or tweets, or blog posts.
