For the first time, TikTok has revealed a part of its secret algorithm. While this isn’t the full picture, it gives us valuable insight into how videos gain traction on the platform.
At its core, TikTok evaluates content using a point-based engagement system. This system determines whether a video should be shown to a larger audience or left behind. Here’s how it works.
TL;DR – How TikTok’s Algorithm Ranks Videos
- TikTok assigns points to engagement actions (likes, comments, shares, and replays).
- Videos start with a test audience of 300 people when first posted.
- Creators need at least 50 points in this test phase to get broader exposure.
- Higher engagement (especially replays and shares) boosts reach.
- The system favors interaction—likes, shares, and rewatching matter most.
Now, let’s break it down.
TikTok’s 5-Point Engagement System
TikTok ranks videos based on a simple point system:
- Likes = 1 point
- Comments = 2 points
- Shares = 3 points
- Watching to completion = 4 points
- Rewatching = 5 points
The more engagement a video gets, the more TikTok pushes it to a larger audience. But engagement alone isn’t enough—videos must pass an initial distribution phase before they can go viral.
The Initial 300-View Test
When you post a video, TikTok immediately shows it to 300 random users. This small audience acts as a testing ground (similar to how Instagram is using Trial Reels).
To move forward, your video must earn at least 50 points from these viewers. Here’s what that could look like:
- 50 likes (1 point each)
- 25 comments (2 points each)
- 15 shares (3 points each)
- 12 full watches (4 points each)
- 10 replays (5 points each)
If the video reaches this threshold, TikTok expands its reach. If not, the algorithm deprioritizes it.
Why Rewatching and Sharing Are So Powerful
Among all engagement types, rewatches (5 points) and shares (3 points) carry the most weight.
- If users watch your video multiple times, TikTok sees it as highly engaging and promotes it further.
- If users send your video to friends, it signals that the content is worth spreading.
This explains why shorter videos (5-10 seconds) tend to perform well. The shorter the content, the easier it is to rack up multiple views per user.
How to Optimize Content for TikTok’s Algorithm
To maximize reach, creators should focus on these key strategies:
1. Hook Viewers Instantly
TikTok’s algorithm prioritizes watch time. If viewers scroll away in the first few seconds, the video won’t perform well. Use strong visuals, text hooks, or surprises in the opening seconds.
2. Encourage Engagement
Ask viewers to like, comment, and share explicitly. Simple calls to action can boost engagement scores and push content further.
3. Keep Videos Short & Loopable
Since rewatches are worth 5 points, creating videos that loop seamlessly increases the chances of multiple plays per user.
4. Leverage Share-Worthy Content
Think about viral trends, relatable humor, or useful information—content people naturally want to send to friends.
5. Post Consistently
Videos that gain early traction have a better chance of snowballing. Posting regularly increases the odds of landing on someone’s For You Page.
Is This the Only Factor in TikTok’s Algorithm?
No. While the 5-point system provides insight, TikTok’s algorithm is far more complex. Other factors likely include:
- Niche relevance: How closely a video aligns with user interests.
- Content quality: Factors like clarity, editing, and audio.
- User behavior: If viewers interact with multiple videos from a creator.
- Shadowbanning & moderation: TikTok can suppress or boost content based on internal rules.
Still, for everyday creators, this point system is key to growing an audience.
Final Thoughts
TikTok’s algorithm rewards engagement—especially likes, shares, and replays.
To get your videos seen, focus on creating compelling, loopable, shareable content.
While there’s likely more going on behind the scenes, this new insight proves one thing: Your audience controls your success. The more they interact, the more TikTok pushes your content.
