How to find which videos are actually driving your subscriber growth
2026-07-16
If you run a YouTube channel, you've probably had this moment. You check your subscriber graph, see it tick up over the last month, and think "great, something's working." Then you try to answer the obvious follow up: which video actually did that? And you realise you have no idea.
I hit this constantly on my own channel, Ozymandias Speedcubing. Subscribers would climb, I'd feel good about it, and then I'd want to know which videos to double down on. Studio would happily show me the line going up, but it wouldn't tell me which upload was doing the work.
Views and subscribers are not the same story
The trap most creators fall into is assuming the video with the most views is the one growing the channel. Sometimes it is. Often it isn't.
You can have a video that pulls a huge number of views and barely converts anyone into a subscriber. People watched, enjoyed it, moved on. You can also have a smaller video, fewer views, that quietly turns a big slice of its audience into subscribers. That second video is the one you want more of. It's the one that made people think "I want to see what else this person makes."
If you're only looking at views, you'll pour effort into copying the wrong video.
What YouTube Studio actually gives you
Studio does track subscribers gained per video. It's just buried, and it only tells you half of what you need.
Go into a video's analytics and you can see how many subscribers it brought in. Do that across your recent uploads and you can start ranking them. That's a real start. But two things make it painful.
First, you're doing it one video at a time. Opening each one, writing the number down, building the picture in your head or in a spreadsheet. For a handful of videos that's annoying. For ninety days of uploads it's a chore you'll do once and never again.
Second, raw subscribers gained is misleading on its own. A video with ten times the views will usually "win" on total subscribers just from volume. To find the video that actually converts well, you want subscribers relative to views, not just the raw count. That's the number that tells you a video punches above its weight. And Studio won't work it out for you.
The manual version
If you want to do this by hand, here's the honest process.
Pick your window. Last 90 days is a good default, recent enough to reflect what you're making now.
For each video in that window, pull two numbers: views, and subscribers gained. Divide subscribers by views to get a rough conversion rate.
Then look at two lists side by side. The videos that gained the most subscribers overall, and the videos with the highest conversion rate. The first list tells you what's driving growth by sheer reach. The second tells you what's genuinely resonating. The videos that show up on both are your real growth drivers. Those are the ones worth studying and making more of.
It works. It's also a decent chunk of an afternoon in a spreadsheet, and you'll want to redo it every month.
The lazy version
I got tired of doing that, which is a big part of why I built Tubient.
Tubient lets you ask your channel a plain question like "which videos have been driving subscriber growth over the last 90 days" and it goes and does the work. It pulls the videos in that window, checks views against subscribers gained, and hands back a written answer telling you which videos are doing the heavy lifting and what they have in common. Not a graph for you to interpret. An actual answer.
It's the exact question that made me build the thing in the first place, so it's the one it's best at.
Try it on your own channel
It's free to try, and connecting a channel takes a minute. Ask it your own version of "what's actually driving my growth" and see if the answer surprises you. It usually does.
