TikTok Algorithm Basics: How the Feed Ranks Videos

Exo Booster download info separates growth claims from mechanics, and the TikTok feed is pure mechanics. No one outside the platform knows the exact formula, but the observable behaviour is consistent.
Videos are tested on small audiences, and the ones that hold attention, earn shares, and spark comments get wider tests. Everything else follows from that loop.
The small audience test
A new video first reaches a sample of viewers, including some followers and some strangers interested in the topic. Completion, rewatches, and shares in that sample decide whether the video earns a larger audience.
This is why the first seconds matter so much. A slow opening fails the test before the best part appears, no matter how good the middle is.
Signals that actually count
Watch time and completion lead. Shares and meaningful comments follow. Likes help but carry less weight than a share, because a share is a public recommendation. Follows from a video are the strongest audience signal of all.
Posting time matters less than most creators think. A strong video posted at an odd hour still finds its test audience, while a weak video posted at a peak hour still fails it. posting time myths covers the evidence.
Myths to drop
There is no shadowban switch for ordinary weak performance, no hashtag count that guarantees reach, and no benefit in deleting and reposting the same video repeatedly. What looks like suppression is usually a topic mismatch or a weak hook.
Consistency helps because it gives the system more data about the account, not because it unlocks a bonus. strong hooks and clear topics beat posting tricks every time.
The feed rewards held attention and real shares. Make the first seconds count, pick one clear topic, and let the test audience do its work.
