"What's a social media manager? And how do they function? I'm a social media idiot eh...hahaha"You handle social media accounts like Twitter, Facebook, Blogs etc.Big Brands, Celebs, etc hire Social Media Managers. Senior writers who help manage our Facebook page are Social Media Managers
On a more serious note,
A person who creates content based on strategies on a per brand and per case basis, develops strategies for individual brands/campaigns, and conducts analysis and reporting on social assets is a Social Media Manager.
A person who develops strategies on how best to market or advertise a brand/business on social and executes them is a Social Media Marketer.
A person who handles SMMs and CMs is a Social Media Director.
Or, as many would have it, all are labeled as SMMs You will usually know what s/he is in 5 minutes.
