SEO targets certain keywords. It takes into consideration how search engines work, what people search for, the search terms or keywords that are typed into search engines, and what is the targeted audience of the search engine. SEO can be used to target different kinds of searches, including image search, local search, video search, academic search, news search and industry-specific vertical search engines.
SMO, on the other hand, stands for social media optimization. According to Webopedia, social media optimization is the process of increasing the awareness of a product, brand or event by using a number of social media outlets and communities to generate viral publicity.â€
