A tiny TikTok caption experiment: 108 views vs 1.8k views

A tiny TikTok caption experiment: 108 views vs 1.8k views

I noticed an interesting pattern while testing TikTok posting through my product today.

I posted two similar videos one day apart.

The first used a very raw caption:

“hello 迪士尼。”

That video got 108 views.

The second used an AI-optimized caption with more context, clearer wording, and a few relevant hashtags:

“Excited to share that UniPost.dev just got its first paid user! 🎉 UniPost.dev is an API that lets you publish one post to all your social media platforms. So happy to see people finding it useful! #UniPost #API #FirstUser #TechStartup #SocialMediaTool”

That one got 1.8k views.

Obviously this is a tiny sample size, and I’m not claiming causation. Different day, different post, different early engagement dynamics, etc.

But it was still a surprising enough difference that I’m going to keep testing it. My current hypothesis is simple: a more descriptive caption may give TikTok more context about who the video is for.

Been deep in the weeds polishing my public API & SDK lately.

The best way to test an API is to actually build something with it — so I spun up a small app on top of my own API.

Immediately found bugs I would’ve never caught with normal testing.

One big improvement:
switched post sending from sync → async + retries
→ success rate went up a lot

Added an extra validation layer too — some platforms are now getting more than 90% success.

Real talk:
I’ve been questioning if anyone is actually using this. Couldn’t even sleep last night thinking about it. Then this morning — got a support email asking about free plan quota reset.

Checked logs:
2 users have been actively sending posts via the API these past few days

They’re on the free plan, but honestly… that made my day.

At least it means this isn’t trash — someone actually needs it.

UniPost currently has a pretty generous free plan.

If you’re building something around social posting APIs, would love your feedback

More platforms are in review and coming soon.
