Social media marketing refers to the process of gaining traffic or attention through social media sites.
Social media itself is a catch-all term for sites that may provide radically
different social actions. For instance, Twitter is a social site designed
to let people share short messages or “updates” with others. Facebook,
in contrast is a full-blown social networking site that allows for
sharing updates, photos, joining events and a variety of other activities.
