A marketing agency can bring professional knowledge, experience, and resources to enhance your online presence, develop strategic campaigns, and reach a broader audience. They can handle tasks like content creation, social media management, and advertising, allowing you to focus on your core design work. However, it’s essential to weigh the costs against potential benefits and consider your specific business needs. If you have the resources and desire to have a hands-on approach, managing your marketing efforts internally might be a viable option. Ultimately, the choice should align with your business goals, resources, and comfort level with marketing responsibilities.
