The document discusses the advantages of hiring a social media agency compared to handling social media in-house. It notes that social media agencies can immediately get to work promoting a business using a clear, strategic plan based on proven best practices drawn from extensive research and experience managing multiple accounts over time.

A social media agency can also more easily adapt to the constantly evolving nature of social media platforms.
