Social media marketing is the process of gaining user engagement or website visitors from social media sites. It happens through sharing content and word of mouth from user to user on social media sites. Many social media sites offer the option of advertising your content which will increase your reach. If we compare SEM with social media marketing, social media marketing is more on a personal level than SEM because you can tailor your ad campaigns to people according to their interests, age, gender, marital status, which users/brands they follow or like and their connection with other users. You can also target the users in the methods seen in SEM such as location, devices, etc.
