The Secret Behind Short-Form Views: What I Learned from a Year of Data

For the past year, I’ve been consistently posting short-form videos on YouTube Shorts, Instagram Reels, and TikTok.

One thing kept bothering me.

Some videos would explode to hundreds of thousands of views, while others struggled to reach even a thousand.

Ironically, I later discovered that the real reason had a lot to do with keywords. But that’s a story for another day.

Today, I want to share the hypothesis I explored before uncovering that truth.

The Starting Point: “If I Increase Retention Rate, Everything Will Improve”

My assumption was simple.

If I wanted more views, I needed to improve my average retention rate.

Average retention rate refers to the percentage of a video that viewers watch. For example, if someone watches 24 seconds of a 30-second video, that’s an 80% retention rate.

My theory was that higher retention would naturally lead to more likes, shares, saves, and ultimately more views.

So the next question became obvious:

How do you increase retention?

First Hypothesis: Hooking Is Everything

The first answer that came to mind was the hook.

You’ve probably heard the phrase:

“The first three seconds determine everything.”

When I examined my own data, the theory seemed accurate.

Videos that successfully kept viewers beyond the first few seconds consistently showed higher retention rates.

If the opening triggered curiosity or excitement, viewers often stayed until the end—even when the editing wasn’t particularly impressive.

On the other hand, if the opening felt ordinary, retention rates collapsed.

But then I noticed something unexpected.

The Variable That Changed Everything: Editing

Some videos performed surprisingly well despite having weak hooks.

When I analyzed them, they all had one thing in common:

Exceptional editing.

The pacing of cuts, subtitle timing, transitions, and overall rhythm kept viewers engaged from start to finish.

That led to a new question:

What’s actually driving views—hooking or editing?

I Analyzed 30 Short-Form Videos with Over 100,000 Views

I selected 30 short-form videos from projects I had worked on over the past year, all of which exceeded 100,000 views.

Then I carefully analyzed their performance metrics.

The results were fascinating.

Both hooking and editing influenced retention.

However, when I dug deeper into the data, one factor clearly stood above the other:

Hooking had a significantly greater impact.

Three metrics revealed the clearest patterns.

1. “Viewed vs. Swiped Away” Above 40% — The Critical Threshold

This was by far the strongest indicator.

During the initial testing phase after upload, videos with a “Viewed” rate below 40% almost never gained traction.

In many cases, they appeared to be permanently suppressed by the algorithm.

On the other hand, every video that surpassed 40% eventually exceeded 100,000 views.

Examples Above 40%

• Uehara Market: 95.1% → 449K views
• Boneless vs. Bone-In Chicken: 59.5% → 332K views
• Cup or Cone: 59.3% → 178K views
• Seasoning Powder: 55.9% → 147K views
• No Sweet, No Ice: 53.2% → 203K views
• Eggplant Side Dish: 52.6% → 126K views
• Braised Baby Potatoes: 49.1% → 221K views
• Email Address: 40.7% → 161K views

Examples Below 40%

• Hooking Principle (Long Version): 31.1% → 1,000 views
• 5 Short-Form Trends: 29.7% → 963 views
• Hooking Principle (Improved): 28.3% → 1,700 views
• YouTuber Minimum Wage: 24.2% → 1,400 views
• 7 Short-Form Trends: 24.1% → 2,100 views
• Doing YouTube for Money: 13.8% → 966 views

The dividing line was almost frighteningly clear.

For my data, 40% separated success from failure.

2. Intro Retention Above 110% — The Algorithm’s First Signal

Sometimes, the retention graph spikes above 100% during the first few seconds.

What does that mean?

It means viewers replayed the opening.

They stopped scrolling and thought:

“Wait, what was that?”

From the algorithm’s perspective, this is an incredibly strong signal.

It suggests that something in the video immediately captured attention.

Example

The “Braised Baby Potatoes” video reached roughly 210% intro retention.

The result?

• 221K views
• 838 new subscribers

Those extra replays in the first second created a massive difference.

3. Final Retention Above 50% — The Power to Keep Attention

The third metric was end retention.

At least half of the viewers needed to make it to the end of the video.

This is where hooking and editing work together.

The hook grabs attention.

Editing keeps it.

Most of the high-performing videos maintained a final retention rate above 50%.

The Conclusion: Hooking Is King

Let’s revisit the three key metrics.

• Viewed Rate → The result of a strong hook
• Intro Retention → The hook itself
• Final Retention → Hook + Editing

Hooking directly influences all three metrics.

Editing strongly impacts only one of them.

That’s not to say editing isn’t important.

In fact, strong editing can sometimes compensate for a weaker hook and help maintain a high final retention rate.

By editing, I mean the process of arranging footage, pacing cuts, timing captions, and creating visual momentum that keeps viewers engaged.

Great editing absolutely matters.

But the data revealed something very clear:

More than 70% of short-form performance is determined by the hook.

The Next Question

At this point, a natural question emerges:

What exactly is a hook, and how do you create one?

That’s what I’ll explore in the next article.

Because after analyzing a year’s worth of data, one thing became undeniable:

The fate of a short-form video is often decided within the first three seconds.
