Creators often talk about "The Algorithm" like it's a moody deity that needs to be appeased. In reality, the TikTok algorithm is a sophisticated machine learning system with a singular goal: Keep the user on the app for as long as possible.

The Hierarchy of Metrics

Not all engagement is created equal. Based on leaked documents and extensive testing, here is the approximate hierarchy of importance for ranking signals:

1. Retention / Completion Rate (Highest Weight): Did they watch the whole video? Did they re-watch it? This is the strongest signal that the content is good.
2. Shares: Sharing is a high-effort action. It brings new users into the app. TikTok loves shares.
3. Comments: Comments indicate active participation.
4. Likes: The lowest weighted metric. It's too easy to double-tap. A like is good, but it won't make you go viral on its own.

The "Testing Phase" (The Batches)

When you post a video, it doesn't go to everyone. It goes through "batches."

• Batch 1 (200-500 views): Shown to a mix of your followers and non-followers who like your niche. If metrics are good...
• Batch 2 (1,000-5,000 views): Shown to a broader audience.
• Batch 3 (10k-100k+ views): The "Viral" stage. This is where broad appeal matters.

If your video gets stuck at 200 views, it failed the Batch 1 test. It likely didn't resonate with your core audience or had a weak hook.

Account Authority (The "Trust" Score)

TikTok assigns a hidden "authority" score to accounts. If you consistently post high-quality content in a specific niche (e.g., Cooking), the algorithm "trusts" you with that audience. If you suddenly switch to posting Gaming clips, your view count will tank because the algorithm doesn't know who to show it to.

The Role of AI Analysis

TikTok uses computer vision and audio transcriptions to understand what your video is about before anyone watches it. This is why "Categorization" is crucial. If TikTok miscategorizes your cooking video as a dance video, it will show it to the wrong people, they will swipe away, and your video will die.

Conclusion

Don't try to "trick" the algorithm. Align your goals with its goals. Make content that keeps people watching, sparking conversation, and sharing with friends. If you do that, the algorithm will become your best friend.
