Quick Answer
TikTok has published how the For You feed picks videos, and it rules out most of the folklore. The factors are your interactions (likes, shares, follows, comments, what you make), the video's own information (captions, sounds, hashtags) and device and account settings, which carry lower weight. Signals are weighted: finishing a longer video is a strong indicator of interest, while viewer and creator being in the same country is weak. Follower count is not a direct factor, and neither is having had a video do well before. Newly uploaded videos, videos under review and spam that seeks to inflate traffic may be ineligible for recommendation.
What TikTok itself publishes about the For You feed: the factors it uses, how they are weighted, why follower count is not a direct factor, and what makes a video ineligible. Checked 16 September 2026.
Percify Clone Yourself
Clone your face and voice, 10 credits once
Five credits for the face and five for the voice, charged once, about 20 cents in total. Every video after that is generated from the clone at 2 credits a second, so a 10 second post is 20 credits, roughly 35 to 50 cents, with no filming.

Most advice about the For You feed is folklore, passed between creators and never checked. TikTok has published its own description of the system, and it settles several of the arguments, including one that affects every new account.
Everything in the next section comes from that post, How TikTok recommends videos #ForYou ↗, published 18 June 2020 and read again on 16 September 2026.
What TikTok says the feed uses
TikTok lists three groups of factors:
- What you do: "the videos you like or share, accounts you follow, comments you post, and content you create".
- The video's own information: "details like captions, sounds, and hashtags".
- Device and account settings: language, country and device type, which TikTok says "receive lower weight in the recommendation system relative to other data points", because people do not choose them as preferences.
Those signals are not equal. In TikTok's words, "a strong indicator of interest, such as whether a user finishes watching a longer video from beginning to end, would receive greater weight than a weak indicator, such as whether the video's viewer and creator are both in the same country".
The line that matters most for a new account
TikTok states plainly that "neither follower count nor whether the account has had previous high-performing videos are direct factors in the recommendation system". A big account tends to get more views because it has an audience, not because the system gives it a handicap.
TikTok also names what is held back: content it has reviewed and judged unsuitable for a general audience, "videos that have just been uploaded or are under review", and "spam content such as videos seeking to artificially increase traffic". Buying engagement is therefore not a neutral shortcut; it is a category TikTok says may be ineligible for recommendation.
What follows from that, and what does not
Follows from it: completion is the signal you can most directly affect, so cut the video to the length people will actually finish rather than the length you have footage for. Captions, sounds and hashtags are how the system reads what your video is about, so write them for meaning rather than for volume. A new account is not waiting for a threshold before its videos can be recommended.
Does not follow from it: posting times, hashtag counts, "reach penalties" and every other number you have seen quoted. TikTok has not published weights, so nobody outside TikTok can tell you them, and this page will not pretend otherwise. Use your own analytics as the test.
If the video is AI, label it
TikTok requires creators to label ↗ AI generated content that contains realistic images, audio or video, including a person shown saying something they did not say. A label TikTok applies itself cannot be removed. This is a posting rule, not a ranking theory, and it applies to talking avatar videos.
Making the videos, if you use an avatar
If you post as yourself without filming every time, the cost is per second rather than per month. On Percify, read on 15 September 2026: Clone Yourself makes your face and voice for 5 credits each, once, which the free plan's 10 credits cover, and InfiniteTalk Fast ↗ renders at 2 credits a second, so a 20 second video is 40 credits, about $0.84 on the Creator plan ($26 for 1,233 credits). Captions burn in at 1 credit a second.

No, not directly. TikTok states that "neither follower count nor whether the account has had previous high-performing videos are direct factors in the recommendation system". Larger accounts tend to get more views because they already have an audience.
By TikTok's own description: what you do (likes, shares, follows, comments, content you create), the video's information (captions, sounds, hashtags) and device and account settings such as language, country and device type, which carry lower weight because people do not choose them as preferences.
TikTok says signals are weighted by value, and gives finishing a longer video from beginning to end as its example of a strong indicator of interest, against a weak one such as viewer and creator being in the same country.
TikTok names videos that have just been uploaded or are under review, spam content "seeking to artificially increase traffic", and reviewed content unsuitable for a general audience, such as graphic medical procedures.
Yes, when they are realistic. TikTok requires creators to label AI generated content containing realistic images, audio or video, including AI generated speech, and a label TikTok applies automatically cannot be removed.
