Definition

TikTok is a short-form video platform owned by ByteDance that distributes videos primarily through an algorithm-driven feed (For You Page) based on content performance rather than the creator's follower count.

TikTok explained

TikTok's defining characteristic is its recommendation algorithm, which delivers content from accounts users do not follow based on watch time, completion rate, shares, and engagement signals. This means a new account with zero followers can reach millions of viewers with a single video if it performs well in early distribution tests. TikTok videos support durations from 3 seconds to 10 minutes, with the platform historically favoring 15-60 second content. Technical requirements include 9:16 vertical format (1080x1920 recommended), H.264 or H.265 codec, and MP4 or MOV container. TikTok's safe zone is particularly important because the right rail (share, like, comment, follow buttons) and bottom bar (username, caption, sound bar) cover significant portions of the frame. TikTok has established the defining aesthetics and pacing conventions for short-form video that YouTube Shorts and Instagram Reels have broadly followed.
