Outsourcing social media is recommended for three main reasons: 1. It allows business owners to delegate non-critical tasks and avoid wasting time, as owners spend on average 4 billion hours per year on delegatable tasks. 2. Outsourcing provides budget predictability by eliminating unexpected costs associated with in-house social media teams like overtime, sick coverage, or sudden software purchases. 3. Experts should handle specialized functions like social media, as outsourcing allows owners to surround themselves with specialist expertise instead of trying to learn every function themselves or relying on inexperienced hires.
