Social media optimization (SMO) involves using social media to drive traffic to websites. There are two types of SMO methods: (1) adding social media features to content like sharing buttons and polls, and (2) promotional activities in social media like blogging, commenting, and posting updates. SMO is related to search engine optimization but focuses more on non-search traffic. It can also improve search rankings. SMO is connected to viral marketing by spreading content through social media instead of friends and family. It is an important part of online reputation management.
