Online platforms are digital spaces that allow users to connect, share, and interact with content or each other. Examples include social media sites like Facebook and Twitter, e-commerce websites like Amazon, and video-sharing platforms like YouTube. These platforms often provide tools for communication, collaboration, and content creation, making it easier for individuals and businesses to engage with a global audience. Many online platforms operate on a freemium model, offering basic services for free while charging for premium features. They rely on user-generated content and data to enhance user experience and drive engagement. Popular online platforms also prioritize user privacy and security to build trust among their users.
