Social media agencies offer a wide range of services, from account creation and management to marketing campaign development and implementation. The cost of hiring a social media agency can therefore vary widely depending on the scope of the project. However, most agencies charge a monthly fee that covers the cost of their time and expertise. For small businesses or those just getting started with social media, this can be an affordable option. For larger businesses with more complex needs in this case, it may be better to hire an agency on a project basis. This way, you pay for the specific services you need.
