Social media allows for global communication and the sharing of content. It has grown rapidly in India, with the number of users doubling every few years. The key social media platforms include Facebook, Twitter, LinkedIn, Instagram, and YouTube. These platforms can be important for businesses for branding, engagement, creating buzz, discoverability, and generating leads. To effectively engage on social media, businesses should post consistently, keep content short and simple, use hashtags and targeting, and measure engagement. They should also focus on quality over quantity and leverage user-generated content.
