X/Twitter Glossary
A thread is a series of connected posts from the same author, used to share longer-form content, stories, or detailed explanations.
Threads allow you to exceed X's character limit by chaining multiple posts together. Each post in a thread is connected, appearing in sequence when viewed. Threads became hugely popular for sharing tutorials, stories, hot takes, and educational content. A well-crafted thread can be more engaging than a single post because it creates a reading experience—people scroll through wanting to see what comes next. Threads also get multiple chances for engagement (each post can be liked/retweeted) and often perform well with the algorithm.
Threads are one of the most effective content formats on X for several reasons: they allow for depth that single posts can't achieve, they increase time spent on your content (good for algorithm signals), each post in the thread can independently get engagement, and they're highly bookmarkable and shareable. Many creators have built massive followings primarily through threads.
