How Does the TikTok Algorithm Work: Myths and Best Practices

Understanding TikTok, and how to use it as a business, means knowing how does tiktok algorithm works.

Once you know that, it’s easier to create content that consistently gets shared, pushing your videos to a much larger audience.

We'll try to cover as many questions as possible and share some best practices to help you improve your TikTok marketing strategy.

TL;DR: How does TikTok’s algorithm work in 2026

• TikTok’s AI-powered algorithm curates each user's For You Page (FYP) based on individual interactions and preferences.
• The two most important ranking factors are watch time/completion rate and the number of times a video has been shared.
• Your video is first shown to a small seed audience (200–500 views). How they react determines whether it gets pushed to a wider audience.
• Views under 5 seconds are flagged as low-quality skips, throttling your reach.
• Shares are the single most important engagement signal, followed by saves, comments, and likes
• Your hook in the first 3 seconds is critical. Viewers decide almost instantly whether to keep watching.
• Adding captions boosts likes by 23% on average and can increase views by up to 80%.
• Video information (hashtags, audio, captions, effects) helps the algorithm serve your content to the right audience.
• The best-performing content is educational, entertaining, inspirational, or a mix.
• Outdated tactics like the batch/ratio theory no longer work in 2026.

How the TikTok algorithm works in 2026

There are several crucial things you need to know about how the TikTok algorithm now works:

• The TikTok algorithm operates as a sophisticated recommendation system that curates the "For You Page" (FYP) for each individual user.
• TikTok’s algorithm analyses every interaction, video element, and user preference to create a unique experience for each person.
• It prioritises content based on user interactions and preferences rather than followers or popularity.
• User interactions form the backbone of TikTok's algorithmically-generated ranking system.
• Shares and comments are important signals
• More important are shares and rewatches
• Shares act as votes of confidence that your content deserves wider distribution.

• Completion rate is one of the most critical metrics for determining algorithm success.
• Videos with captions generate 23% more likes on average than those without captions
• Your content is shown to an initial seed tier (200–500 views), and the algorithm uses this to evaluate how your existing followers react before triggering broader FYP distribution
• Your videos need to hit an average completion threshold of up to 70% for them to be showed to more people
• Views under 5 seconds are now flagged as low-quality skips, throttling reach.

What’s absolutely crucial for every TikTok video, if you want to master the algorithm, is the hook.

The opening moments of your TikTok video are absolutely crucial for success.

The attention span for social media content has decreased to approximately 8 seconds. Research consistently shows that viewers decide whether to keep watching within the first 3 seconds.

Unlock the potential of TikTok hashtags

Connect to the right viewers by using Sendible's smart search to identify, manage, and track relevant hashtags. Use 3 to 5 relevant hashtags; mix popular, niche, and branded hashtags.

Important note: Even if you curate your feed to perfection, that doesn't mean you'll limit yourself to only the content you know and love.

Every now and then, you might be recommended a video that's been well-received by other users with similar interests. That way, you'll always be able to expand your interests and learn about new things.

Core ranking signals that drive distribution

A lot of content creators experimented with the algorithm and suggested various theories. But even though there are many unknowns, there are some factors that we know trigger the algorithm and get you in front of a bigger audience:

User interaction

Much like every other social media algorithm, the level of engagement your video gets is one of the two most important factors. The engagement metrics include:

• Likes
• Comments
• Saves
• Shares: Being the MOST IMPORTANT ranking factor.

Watch time

The second important factor is the watch time, and even more precisely, the completion rate.

If you dig into the TikTok analytics (on the bottom right of your video, click More data), you'll see that the watch time is separated into three categories:

• Total Play Time (TPT)
• Average Watch Time (AWT)
• Watched the full video

The greater the percentage of the audience that watched the full video, the greater the chance your video will reach a larger audience and potentially go viral.

Does rewatching a TikTok video count as a view?

When it comes to watch time and views, this is one of the most frequently asked questions. And the short answer is yes.

The moment your video starts playing, it's counted as a view. If the video auto-plays or loops, or a viewer comes back to watch it multiple times, all of those count as new views.

In the More data section, you can see the Reached Audience metric. Compare it to the number of times your video has been played, and you'll get the idea of how many times it has been replayed.

Even though the replay metric doesn't exist, it still affects your video's overall performance, as it signals to the algorithm that your audience finds it interesting.

Video information

While not as important as engagement rate and watch time, the information you include in your videos helps the algorithm show your video to the relevant audience, which can positively impact the number of interactions it gets.

TikTok video information includes:

• Copy
• Audio
• Hashtags
• Effects (visual and audio)
• Captions

Location and language

The algorithm takes into account your device settings, such as:

• Posting location
• Language preferences

While you can work around the language by adding closed captions, the posting location is a bit trickier, and it might take some time for your content to reach a global audience.

I have personally experienced the side effects of this factor, as I live between Serbia and Italy.

When I posted videos from Serbia, they were only shown to the Balkan audience. While in Italy, my videos were seen by people in Italy and in some other EU countries.

The positive thing is that when I came to Italy, my "Serbian" videos reappeared as if I had posted them for the first time!

The posting location factor is significant if you're a digital marketing agency or a social media marketing expert with international clients.

“Not interested” TikTok audience feedback: Does that impact reach?

Remember how we told you that every now and then, TikTok presents you with a video on a topic different from the ones you're used to seeing?

Well, each user has access to the "Not Interested" option. This means one can let the algorithm know they don't like a particular type of content, which helps TikTok better understand what content is appropriate.

But what does this mean for you as a marketer?

It means you really need to consider the information you include in your video and how it relates to your target audience.

Avoid adding irrelevant trending hashtags and hopping on viral trends that your audience doesn't find valuable, just to increase reach.

Debunking outdated TikTok algorithm myths

Over the last few years, there have been various theories, often posted by influencers, about how the TikTok algorithm does or doesn’t work.

Fortunately, the TikTok algorithm and our understanding of it (including TikTok’s willingness to share more information) have evolved since then. So has our ability to decode complex social media algorithms.

For example, the following theories have been debunked:

1. How many followers an account has

In 2023, thanks to TikTok putting this out, people thought your follower count didn’t matter:

“While a video is likely to receive more views if posted by an account that has more followers, by virtue of that account having built up a larger follower base, neither follower count nor whether the account has had previous high-performing videos are direct factors in the recommendation system. - TikTok Product blog.”

Now, we can clearly see that the number of followers you have does matter. The more followers, the greater the chance your video will be seen by a larger audience.

2. Ratio and batch theory

As proposed by @feliciaforthewin in 2023. At the time, both ideas worked. However, the TikTok algorithm has evolved since then and is now further infused with an AI recommendation engine.

Unfortunately, both theories no longer work to boost engagement and views on TikTok in 2026.

3. Not quite debunked: The watch time theory

Social media coach and content creator @coachstone ran an experiment on both of his TikTok accounts. The goal was to build a community of followers who know, like, and trust him. His experiment resulted in over 150,000 followers on each account in less than three months.

Here are some of his conclusions:

• Nobody cares when you post your video. Time now makes an impact. Take a look at our article here.
• And more information here about the optimal social media posting frequency.
• The most important factors are watch time and engagement. Still true!
• People want value in the form of education, entertainment, or inspiration. Still true!

He then confirms the batch theory before laying out the "success metrics" from most to least important:

1. Watch time
2. Shares
3. Saves
4. Comments
5. Likes

According to him and many other marketers, the algorithm prioritises watch time because it wants to keep people on the platform. And given the average watch time per user and the fact that short-form videos have become the leading social media trend thanks to TikTok, it's pretty safe to assume this is a valid point.

The most exciting part of this theory is the percentage of people who watched the entire video you need to have for your content to be seen as successful by the algorithm:

• 15-second video or less: 100% watch time
• 16-30 second videos: 75% watch time
• 31-60 second videos: 50% watch time

My verdict:

We all witnessed that the most viral videos are one of the following:

• Very short
• Extremely valuable
• Tutorials
• Entertaining (in both a good and a bad way)

Why?

Because you watch them until the end. And sometimes the creators create such perfect loops that you don't even notice the video has restarted.

And while the percentages coach Stone suggested are pretty rough, they do make sense.

For example, consuming super-short videos is easy, and most of us will stick around for those few seconds. That is why the percentage can reach 100% and why you'll see so many "trending" 7-second videos with no value whatsoever.

Why TikTok SEO controls long-tail traffic

TikTok is now an integral part of how people find information online. Both as a substitute to search engines, and one of the ways that AI tools, and AI-generated answers (AI Overviews and AI Mode) source and cite information.

That’s right, in 2026, TikTok is effectively part of your SEO strategy!

TikTok's search functionality has become increasingly sophisticated and robust, making keyword optimisation absolutely crucial for long-term discoverability success.

10 ways to work with the TikTok algorithm in 2026

We've faced numerous algorithm changes and updates across every social media platform, but we've always managed to adapt and come out stronger.

As with every social media platform, you need to be consistent in publishing the content your audience wants to see. Use your analytics. Find what works. Then do more videos like that.

Here are ten evergreen ways to work with the TikTok algorithm to create high-impact content in 2026:

Hack #1: Do extensive research as soon as you open a TikTok account

Find out what your target audience likes, make a list of TikTok influencers from your niche, and start engaging with their content.

Hack #2: Curate your For You Page (FYP)

Doing this first will help you understand how the algorithm works and stay on top of the trends in your niche.

Hack #3: Hook your audience within the first seconds of your video

Full watch time and shares are the two strongest indicators that your content is valuable.

But first, you must ensure the viewers start watching it. For brands starting out on TikTok, the first few months are all about building your audience. The only way to do that is through engaging hooks that pull more and more people into your follower network.

Cross-promoting your content on other platforms is a good way to do that in the early-days.

Hack #4: Use niche hashtags

The algorithm uses bits and pieces of video information to deliver your content to the right audience. Remember: TikTok wants its users on the platform as much as possible. So it's in both your and its interest that you use relevant hashtags.

Hack #5: Use trending audios

TikTok offers an extensive commercial music library, but it's best to start with trending audio.

Not because they'll immediately get you in front of a vast audience, but because the viewers will know what to expect from your video from the first sound of it. Trending audio combined with a catchy hook might just be your ticket to the For You Page of your new audience.

Hack #6: Add captions to your video

Adding subtitles and captions can increase video views by 80%. Why? They help you communicate your message more effectively, highlight the most significant information, and make it more engaging and accessible to everyone.

Hack #7: Experiment with short-form and long-form videos

Videos between 15 and 60 seconds tend to achieve higher engagement rates because they're more likely to be watched completely multiple times, sending strong positive signals to the algorithm.

The only metrics that matter now and boost your brand presence are the completion rate and "Save" velocity (the number of times your videos are saved).

Hack #8: Focus on creating a community

Building a strong community is essential for every brand that uses social media marketing to promote its business. Instead of accumulating thousands of irrelevant followers that won't engage with the following video you publish, try to find a way to create a meaningful relationship with your target audience.

Hack #9: Create educational, entertaining, or a combination of the two: edutainment

Successful TikTok content consistently falls into three primary value categories:

• Entertainment
• Inspiration
• Education.

The most effective and viral videos often strategically combine elements from multiple categories, creating content that's simultaneously informative and engaging.

Hack #10: Adjust trends to your brand

Don't copy - focus on giving a unique touch to viral trends. And more importantly, use them to present a different side of your business while staying on brand.
