Social media management is everything it takes to run your business's social accounts well: deciding what to say, making the posts, publishing them on a steady schedule, and talking with the people who comment and message. It's less about going viral and more about showing up, consistently, as the business your customers already know.
For most established businesses, social isn't where the first sale happens. It's where people go to check you out. A prospect hears your name, then looks you up. If the last post is from months ago, or reads like it was written for any company in your industry, that's a quiet strike against you.
Done right, social does a few plain jobs. It proves you're open and busy. It shows the people and the work behind the logo. It answers questions before they become objections. And it gives your happiest customers a place to say so in public.
