Social Media Optimization (SMO) is the process of optimizing a website or content to increase its visibility and reach through social media platforms. This involves creating and sharing content on social media sites such as Facebook, Twitter, Instagram, and LinkedIn, among others, to attract more followers and engage with them.

The goal of SMO is to create shareable content that will encourage users to share it on their social media profiles, thereby increasing the reach of the content. SMO also involves optimizing the content for social media platforms by using relevant keywords, hashtags, and meta descriptions.

SMO is an important aspect of digital marketing as it helps businesses to increase their online presence, build brand awareness, and drive more traffic to their website. It also helps in improving search engine rankings and can be used to complement other digital marketing strategies such as Search Engine Optimization (SEO) and Pay-Per-Click (PPC) advertising.
