Social media optimization (SMO) is a set of methods for generating publicity through social media, online communities and community websites. Methods of SMO include adding RSS feeds, social news buttons, blogging, and incorporating third-party community functionalities like images and videos. Social media optimization is related to search engine marketing, but differs in several ways, primarily the focus on driving traffic from sources other than search engines, though improved search ranking is also a benefit of successful SMO.

Social Media optimization is considered an integral part of an online reputation management (ORM) or Search Engine Reputation Management (SERM) strategy for organizations or individuals who care about their online presence.
