Social media algorithms prioritize engagement depth. On TikTok, the comment drawer is a primary engine of overall session length. When a user opens the comment panel, video playback loops continuously in the background, driving up the clip's completion rates and replay signals.
Visual memes supercharge this metric. An eye-catching graphic stops vertical scrolling within the comment drawer. A viewer pauses to look at the surreal design, checks the parent comment to see if it makes sense, and realizes it does not. That momentary confusion adds 2 to 4 seconds of dwell time per user. Across a clip with millions of views, those fractions of a second tell the recommendation engine that the post holds viewer attention exceptionally well.
Early commenters know this mechanism intuitively. Securing the "top comment" on a trending post provides massive account visibility. Dropping a recognizable, high-contrast visual like "Cherry On Top" within the first 15 minutes of a video going live virtually guarantees early likes. The platform's ranking system pushes heavily liked comments to the top, creating a compounding loop where the image stays pinned for the lifetime of the video.
