How the TikTok algorithm works in 2026

“The algorithm” is really a set of recommender systems, one for each feed: For You, Following, Friends, LIVE, search and more. The one that decides most of a video's reach is the For You feed, which TikTok called in 2020 the place “where most of our users spend their time”. Its Creator Academy breaks the For You feed into six steps:

Before any of that, a video has to be eligible. Every upload goes through moderation, a mix of automated checks and human moderators, and TikTok says the system only picks from videos that pass. Its 2020 post added that videos that have just been uploaded or are under review may not be eligible for recommendation yet, which is one reason a new video can start slowly.

The prediction step is how a video reaches people who've never heard of you. TikTok's Help Center says some of its systems consider “interactions from others who appear to have similar interests”: if one viewer liked videos 1, 2 and 3, and another liked 1 to 5, the first may be shown 4 and 5. A video spreads to people like the ones who enjoyed it first.

TikTok's Help Center sorts what shapes the For You feed into three groups, with examples of each:

• User interactions: content people like, share, comment on, and watch in full or skip, and the accounts they follow back.
• Content information: sounds, hashtags, the number of views a video has, and the country it was published in.
• User information: device settings, language, location, time zone and day, and device type.

The weighting is the useful part. “For most users, user interactions, which may include the time spent watching a video, are generally weighted more heavily than others,” TikTok says, and how much each factor counts “can change over time”. In 2020 it gave an example of the difference: a strong signal, like “whether a user finishes watching a longer video from beginning to end”, counts for more than a weak one, like whether the viewer and the creator are in the same country. Device and account settings get lower weight because, as TikTok put it, people don't actively express them as preferences.

Each feed weighs things differently:

Search stands out among the video feeds: there, what a video says matters more than how people reacted to it. More on that below. For the length of video people watch through, see how long a short video should be.

Not directly, for the For You feed. TikTok's 2020 post said that while an account with more followers is likely to get more views, “neither follower count nor whether the account has had previous high-performing videos are direct factors in the recommendation system.” Its Help Center today lists follower count among the signals for the LIVE feed and for suggested accounts, but not for For You.

Followers still help in two ways:

• The Following feed. Your followers can see your posts there, ranked by how they use the app, so they can be among a video's first viewers, and their reactions feed what happens next.
• Features. TikTok LIVE (in most regions) and a website link in your profile need 1,000 followers; Creator Rewards needs 10,000. See how to get followers on TikTok for the plan to get there.

The other half of that 2020 sentence matters as much: a past hit isn't a direct factor either. A new account's video can reach the For You feed, and a big account's next video still has to hold its first viewers. For new accounts, see how to warm up a new account.

Before ranking comes eligibility. TikTok's Community Guidelines mark some content “FYF Ineligible”: it stays on TikTok, but the For You feed won't recommend it. For anyone posting clips, the rules that matter most are about originality. TikTok's Creator Academy defines unoriginal content as:

• Content copied completely from others.
• Content largely repurposed from another source without adding any creative edits.
• Content combined from multiple sources with little or no added information or value.
• Content with someone else's visible watermark or logo on it.

The Community Guidelines that took effect on September 24, 2026 also list “low-quality or minimally edited content, such as short clips made from GIFs only”, and keep posts that try to manipulate people into “inflating likes or follows”, like “like-for-like” promises, out of the feed too.

It can reach past a single video. TikTok says that if you repeatedly post content unsuitable for the For You feed, “your account and posts won't appear in the For You feed and will be harder to find in search.” You get a notice in your inbox and under your username, with a way to appeal, and TikTok may restore the account on its own depending on how much of your content is unsuitable. Account check, in TikTok Studio under More tools, scans your account and your last 30 posts for problems.

A video that isn't in the For You feed can still be found in search and on your profile, and TikTok says a video with few views hasn't necessarily broken a rule: TikTok Studio's analytics show whether a video was made ineligible. TikTok doesn't list which edits are enough, so for a clip of someone else's video, make the cut, framing, captions and hook your own, and make sure you have the right to post it: see is clipping legal?

Here's each signal TikTok names, what to do about it, and where TikTok Studio shows whether it worked:

Captions do double duty: TikTok's Creator Academy says more than 30% of TikTok users watch with the sound off, and text on screen is part of what search reads. Keep that text clear of TikTok's buttons with the safe zone checker.

Every one of these is decided by the first seconds, because a skip ends the rest. The hook generator gives you opening lines built to stop the scroll, and short video hooks has examples by type. For the full set of tactics, from the first frame to posting times, see how to get more views on TikTok.

Search runs on a different balance. TikTok's Help Center says content information, “how well the content matches the specific term entered”, is generally weighted more heavily there than anything else. Its Creator Academy says search “values relevance over video views and engagement”, and that relevance comes from video captions, video text and hashtags, with results sorted by relevance and engagement together.

That makes search a place where a new account with no track record can compete on its words:

• Say the topic three ways: in the caption, in text on screen in the first seconds, and in the spoken words captioned on screen.
• Describe the video accurately. TikTok warns that stacking popular but irrelevant keywords will “negatively affect your video traffic”.
• Pick topics people are already looking for. Type “Creator Search Insights” into TikTok's search bar for topics people search often; its Content gap filter shows ones with lots of searches but few good videos yet.

TikTok also shows search suggestions on videos, built from things like what comments say and what people search for after watching, so a clip that names its subject gives it the words to suggest.

The factors TikTok lists today are the same three groups it described in 2020. What has changed is who oversees the algorithm in the US and how much control viewers get, and the rules were reissued:

• A new US home for the algorithm. On January 23, 2026, TikTok's newsroom posted the announcement of the TikTok USDS Joint Venture, a majority American-owned company set up to secure US user data, apps and the algorithm. It said the joint venture “will retrain, test, and update the content recommendation algorithm on U.S. user data”, and that the algorithm will be secured in Oracle's US cloud. It didn't say how the retrained system will weigh things differently, and the Help Center still lists the same factors.
• New guidelines, the same For You feed rules. TikTok released its current Community Guidelines on August 25, 2026, and they took effect on September 24, 2026. The For You feed standards read as they did in the 2025 version: TikTok avoids repeatedly recommending content that could lead to a negative experience, such as extreme fitness or dieting, and may interrupt repetitive recommendations during a crisis.
• More viewer controls. In June 2025 TikTok launched Manage topics, sliders that set how much of over 10 popular topics, like sports or travel, a viewer sees (they don't remove a topic entirely), and AI-powered keyword filters that also catch similar words. In November 2025 it said it would start testing a control there for how much AI-generated content shows up.

Viewers can also refresh their For You feed (Settings and privacy, Content preferences, Refresh your For You feed): TikTok shows them popular content and relearns their taste from how they react, and it can't be undone. And when a viewer taps Not interested, TikTok shows them less like it; for Creator Rewards, views from people who said they're not interested don't count as qualified views at all.

If followers aren't a direct factor and each video is judged on its own viewers, then every clip is a separate test, and you can't know in advance which moment people will finish and share. Three rules follow from what TikTok says:

• Post more tests, not repeats. TikTok said in 2020 that the For You feed doesn't recommend duplicated content, and generally won't show two videos in a row by the same creator or with the same sound. Post different moments, each with its own hook, and spread them through the day.
• Make each clip your own edit. TikTok doesn't say which edits are enough, so make the clip clearly yours: your cut, 9:16 framing and captions. A campaign or the creator's permission is what lets you post it.
• Know which money it can earn. Creator Rewards pays only for original content filmed and produced by you, so clips of other people's videos don't earn from it. Clippers get paid by campaigns instead: see how to make money clipping, how much TikTok pays, and the TikTok money calculator if you post your own videos.

The catch is the volume of good tests. Finding a dozen moments in a long video, cutting each on a clean sentence, reframing it to vertical and captioning every word can take longer than watching the video. Clyper does that part: it reads the transcript to find the moments that stand on their own, cuts on whole sentences, frames 9:16 on whoever's talking, captions every word, and gives each clip a hook score so you know which to post first. You still post them yourself. For how YouTube's system compares, see the YouTube Shorts algorithm.
