A social media feed is a continuously updated stream of content that users see when they log into platforms like Facebook, Instagram, or Twitter. This feed includes posts, images, videos, and updates from friends, family, and accounts that users follow. The content is often personalized based on user preferences and interactions. The feed is designed to keep users engaged by displaying a mix of new and trending content. Algorithms determine what appears in each user's feed, taking into account factors like popularity, relevance, and user behavior. This helps create a unique experience for each individual.
