TikTok's recommendation algorithm rewards early engagement, so posting just before peak hours beats posting at peak.
The recommender systems on every major platform reward early engagement velocity. The first 30–60 minutes after a post lands either pump it into more feeds or quietly bury it. Posting when your audience is awake and scrolling is how you put your thumb on that initial-velocity scale.
The data above is the published baseline — every audience has its own peaks. If you're a Vyrable account, the in-app scheduler reads your account's actual engagement history and proposes per-platform best times tuned to your followers, not the average follower.
