Social media presence is as important as a business card...and graphic design is needed in order to engage your audience.
Platforms like Twitter, Instagram, etc. are where you can establish and maintain your brand's followers and clientiele. And with audience engagement comes content. Remember that it's not enough to make posts, but your content has to stand out against tons of other brands competing for your potential viewers. Make quality content so that your audience keeps coming back.....and get those headers and profile pictures together. Don't be raggedy. (Pls note that some of the examples are prior to Covid-19 and shutdown protocol.)
