Social Media Marketing, or SMM, is a key part of digital marketing that helps promote brands, products, or services using platforms like Facebook, Instagram, LinkedIn, YouTube, Twitter, and TikTok. It involves making and sharing interesting content such as posts, videos, and stories to reach the right people, make more people know about the brand, and bring them to the website. The main aim of SMM is to create a good connection with customers by getting them to like, comment, share, and interact with the brand, which helps build loyalty. Companies use SMM to show off their products, get potential customers interested, and increase sales in a way that’s not too expensive. By looking at how people engage with content and what they do online, marketers can see what’s working and make better plans over time. In the busy digital world, social media marketing helps brands become more known online, earn trust, and keep in touch with their customers.
