Thread

A thread is a chain of linked posts published in sequence so a longer idea unfolds across multiple short entries, common on X (Twitter) and the Threads app. It matters because it lets you go deep within a short-post platform while each entry stays scannable, and a strong first post can pull readers through the whole chain for outsized reach. Threads are used for storytelling, step-by-step guides, hot takes, and case studies. Effectiveness is measured by the first post's engagement, thread completion, bookmarks, replies, and profile clicks or follows it generates.
