Growth experimentsChapter 02 / Instagram

I started learning Instagram. 5 days later, I posted a reel that reached 2.1M views. 16 days later, I posted one that reached 5.1M.

From March 8 to March 24, I posted 34 reels. Here are the actual videos, changes, and lessons behind the results.

01 / The beginning

How I started

When I don’t know how to do something, my strategy is to find 5 specialists who are experts in this particular domain, talk to them and really narrow down who I wanna learn from.

This experiment came after learning from one of them. I had posted on Instagram before, but March 8 was the start of putting those lessons into focused practice. Over the next 16 days, I posted 34 reels. This chapter shows what came out of that experiment.

02 / First comparison

Your hook should capture the audience’s attention in the first three seconds

For a simple reel I want to go viral, I focus on three things: a hook that captures attention, a visual that shocks the audience, and a caption that delivers the full story. I aim for about 7 seconds.

What I learned

I focus on three elements in an Instagram reel: a hook that sparks curiosity, a shocking visual that delivers the emotion, and the full payoff in the caption. While someone reads the caption, the video can keep looping. A caption that holds their attention gives them a reason to stay longer.

The first version reached about 12,600 views. Then I used the same hospital footage, shortened it to 7 seconds and made the hook more direct. And bam, 2.1 million views.

04 / Second comparison

This 5.1 million-view video took me 10 minutes to make

I found an old clip in my photos of 3 friends dancing in my kitchen. I cut it to about 7 seconds, used Tame Impala’s trending song “Dracula”, and added the on-screen hook: “POV: You’re a man and you live with 3 girls in Amsterdam.” The written caption was simply: “Ik ben niet homo. IFYKYK.”

I chose it because I thought the moment was fun. It took off as a trial reel. Later, I repurposed the same video to see if it would take off again, switching the audio to Sabrina Carpenter’s “House Tour” and updating the caption. It worked again: the repost reached almost 394K views.

What I learned

The footage and on-screen idea worked again, even with different music and a different caption. For me, this supports my hypothesis: a simple reel of about 7 seconds, paired with trending audio, can encourage people to watch again.

I still focus on the same three elements when aiming for a viral reel: a hook that sparks curiosity, a shocking visual that delivers the emotion, and the full payoff in the caption.

05 / Take it with you

A process you can try

Start with the footage you already have.

  1. 01

    Look through footage you already have.

  2. 02

    Choose a moment you genuinely find interesting or funny.

  3. 03

    Write a hook that makes someone curious enough to keep watching.

  4. 04

    Post, learn from the result, and test a new hook or tighter cut before abandoning the idea.

That’s the experiment.

Your next viral reel might already be in your camera roll.
