The TikTok Algorithm: How Does It Work and How Can It Help You?

Imagine the TikTok algorithm explained as a points system that tracks interactions between each user and the content they watch. Certain interactions signal they liked it, others that they didn’t. The algorithm uses that data to create content recommendations tailored to individual users. 

Want more likes and views on TikTok? Then you need those key ranking signals working in your favour. 

Engagement metrics, such as:

• Likes 
• Comments 
• Watch Time 
• Saves
• Shares

User interactions, such as:

• Other accounts followed 
• How similar users interacted with content

Video information, such as:

• Captions 
• Hashtags 
• Sounds
• Spoken words 
• Text overlays 

Device and account indicators, such as: 

• Country 
• Language 
• Device 
• Category selection

FYP stands for “For You Page,” TikTok’s default homepage that loads when you open the app and provides a personalised video feed.

Brand-new accounts show users videos recently popular within their demographic. As each user interacts with each video, the algorithm learns what they like, predicts what else they’ll like, and then shows it to them. 

FYPs grow increasingly personalised as users spend more time on TikTok, although videos outside their expressed interests will pop up now and then to diversify the feed.

Engagement 

The TikTok algorithm for views is more interested in how long people watch than in how many people watch. When it comes to watch time:

• Low watch time (when content is quickly skipped) signals disinterest and is penalised.
• High watch time (when content is regularly watched start to finish) signals engagement and is promoted.

It is the most important metric for ranking on TikTok. “Watch time in the first few seconds is the strongest ranking signal,” writes Hootsuite’s Hannah Macready.

Since 71% of TikTok users decide whether to keep watching within three seconds, that’s how long you have to capture their interest – hence the platform’s oft-cited Three-Second Rule.

Let’s see how Phoenix Ross makes those first three seconds count. 

Strong opening hooks immediately spark interest:

• Visual hook: Martini glass filled with fluffy cream and a Kinder Surprise Egg. 
• Verbal hook: “If I sold this in America, I could get 12 years in prison.”
• Text hook: The above as a caption.

All this happens within the first few seconds, and it is entirely intended to keep you watching. 

Ross continues with:

• Quick cuts that cover the entire cooking process
• Upbeat narration explaining why the items are banned
• Final verdict on how it tastes

It’s an engagement masterclass.

Hashtags

Adding relevant hashtags to the “describe your video” caption box helps TikTok categorise content and show it to the people most likely to watch. You’re essentially telling TikTok who to target. 

“Current best practices suggest three to five hashtags,” writes Kirsti Lang for Buffer. “Include trending hashtags along with evergreen ones for best results.” 

Take this video from comedian Munya Chawawa:

Among the hashtags used are #comedy and #satire, which signal his content style. Meanwhile, #britain and #politics outline the audience and subject while boosting his video’s visibility in the wake of the 2026 local elections.

Trending 

“Jumping on TikTok trends may seem cliché,” writes Sprout Social’s Mahnoor Sheikh. “But it can introduce your content to communities and accounts you’d usually never reach.”

That includes trending:

• Audio 
• Hashtags 
• Effects 
• Sounds and songs 
• Memes 
• Challenges 

Capitalising on trends can boost your visibility. Just ensure that you’re adapting them to your content rather than simply jumping on the bandwagon. 

For example, @twomomsinmotion adapted How You Like Me Now? by the Heavy into a video when it started trending in July 2026. 

Mix of Short and Long

“While keeping videos punchy is still important,” writes Sheikh, “the algorithm has shifted to reward videos over one minute long.”

TikTok isn’t just about ultra-short content these days. A study of 1.1 million TikToks shows videos over 60 seconds receive at least 43.2% more reach and 63.8% more watch time than shorter ones. 

You needn’t drop sub-60-second videos altogether, but you should mix in longer videos that really use those extra seconds to:

• Increase clarity and value, as Olivia Megan does in this advice-packed TikTok

• Edit down a longer story or experience, as Adam Moran does in this seven-minute eating challenge

Keywords 

Like hashtags, keywords tell the algorithm who content is for, which improves people’s ability to search for it. That’s more important than ever now that a reported 49% of consumers use TikTok as a search engine. It’s a substantial marketplace on which you don’t want to lose out. 

Experts recommend using one primary keyword and two or three closely related secondary terms per video. 

Find phrases your audience is actively searching by:

• Typing a broad topic into TikTok’s search bar, and then looking at autocomplete suggestions and the “Others searched for” section
• Visiting the Creative Centre’s Keyword Insights section to check the popularity of specific terms

Ensure that those keywords accurately reflect the video, and then add them naturally to:

• Spoken audio
• Onscreen text
• Description

Niche

“The TikTok algorithm in 2026 prioritises community-aligned content over random viral hits,” Macready writes.

That makes growing your TikTok following within one specific community smarter than trying for wider virality. Sticking to the same topics, adopting a set style, and narrowing to a specific niche may seem repetitive or liable to restrict your TikTok earning potential, but it works.

Ali-A’s video library is a great example. Tightly focused on Fortnite with similar visuals and narration, they’ve helped him earn over 2.1 million followers and 38.4 million likes.

Slow start

Content stuck in 200-view jail? The algorithm probably tested it with a small sample, found they mostly scrolled away, and then stopped promoting it. Basically, you’re not giving people a reason to keep watching within those vital first three seconds.

Standards violations 

TikTok removes content “identified as violating Community Guidelines” and won’t recommend videos in the For You feed that “does not meet our For You feed eligibility standards.” Check their guidelines and standards if the algorithm seems to ignore your content altogether, especially if you’re hoping to make money on TikTok. 

Deletion

Deleting videos removes some of the data points TikTok’s algorithm relies upon, negatively impacting your account. It also signals your content may not be good enough to promote. After all, if past content was deleted, why should future videos be pushed? Frequent deletion can even trigger spam filters that dramatically limit (aka “shadow ban”) your account.

Lack of community

Does commenting on TikTok help the algorithm? Yes! When people comment on your content, that signals engagement. Same goes for saves, likes, and shares – all of which are signals generated by engaged communities. 

If the algorithm seems against you, start responding to comments, collaborating with similar creators, and adding CTAs that prompt viewers to interact. That also helps land paid TikTok content jobs, since clients tend to value strong communities. 

Inconsistent posting

Sporadic uploading can confuse both your audience and the algorithm. Neither will know when to expect your content! Research that covered 11.4 million TikTok posts from over 150,000 accounts suggests two to five posts per week is ideal.
