Social media marketers are marketing specialists who use social media platforms to promote a company's offerings. They often use platforms like Facebook, Instagram, Twitter, and TikTok to reach new customers, engage with current ones, and announce new products or services. Social media marketing is the use of social media platforms to connect with your audience to build your brand, increase sales, and drive website traffic. Social media marketing agencies produce the content that clients use to connect with key audiences over social channels. Account reps and creative talent write posts, produce videos, and create content clients use on social.
