Social media optimization (SMO) package was originally designed to drive traffic from social media sites such as bookmarking sites and social networks. However, SMO is now significantly more important and not simply because social networking has grown but because SMO also improves SEO performance. Good SMO will drive traffic from both direct social site referrals and from search engines.
