SMO is short for social media optimization.
Social media optimization refers to optimizing webpages to maximize social media sharing and increase brand awareness. This can take the form of adding social media sharing on all piece of content marketing, calls to action to share the content at the end of each article, links to your social media profiles on your home page and consistent branding across your home page and social media profiles. This is an essential aspect of social media marketing.
Social media can generate traffic to your website, but most traffic to websites still occurs as a result of searches via search engines. This doesn’t negate the value of social media optimization. Social media is one of the best sources for backlinks that search engines trust, as compared to pasting links anywhere you can. And these links are given more weight by search engines when determining the quality of your content compared to link spam or relevant links posted on other sites.
