"Likes" are a way for users to express approval or enjoyment of content on social media platforms, such as Facebook, Instagram, or Twitter. When someone clicks the "like" button on a post, photo, or comment, it indicates that they appreciate or resonate with that content. This feature helps users engage with each other and discover popular or trending posts. The number of likes a post receives can influence its visibility and reach. Content with more likes is often shown to a larger audience, as platforms use algorithms to promote popular posts. This can encourage users to create more engaging content to attract likes and increase their online presence.
