Correct Answer: (a) Easily creating publicity by social networks
Note: Social media optimization (SMO) is the use of social media sites to manage and enhance an organization's message and online presence. It involves using multiple outlets and communities to generate publicity and increase awareness of a product, service, brand, or event. As a digital marketing strategy, SMO can increase awareness of new products, connect with customers, and mitigate damaging news. SMO is similar to search engine optimization (SEO) in that the goal is to generate web traffic and increase awareness for a website. SMO's focal point is on gaining organic links to social media content and easily creating publicity.
