What Is a "Like"?

In the digital age, a "like" is more than just an expression of preference—it's a form of engagement. Originally popularized by Facebook, the "like" button allows users to quickly show approval or interest in a post, photo, video, or comment.

Why Do People Use "Likes"?

People use likes for various reasons: to support friends, signal agreement, boost visibility of content they enjoy, or even as a low-effort way to stay connected. Psychologically, giving and receiving likes can trigger dopamine release, reinforcing social validation.

How Do Platforms Use Likes?

Social media algorithms often prioritize content with more likes, interpreting them as signals of quality or relevance. This can increase a post’s reach, influence ad targeting, and shape what users see in their feeds.

The Evolution of "Like"

While Facebook uses a thumbs-up "Like," other platforms have expanded the concept—Twitter has "hearts," LinkedIn uses "reactions," and Instagram combines likes with comments and shares. Some platforms, like Instagram, have even tested hiding like counts to reduce social pressure.
