The subscribe QR code, and the parameter nobody uses
One scan opens YouTube with the subscribe prompt already showing. The same trick works on any link you share.

"Search my channel name" loses people. Every extra step between wanting to subscribe and subscribing costs you some of them, and a spoken channel name is three or four steps: remember it, spell it, find the right result among the wrong ones. A QR code is one.
What it actually encodes
Your channel URL with ?sub_confirmation=1 on the end. Scanning it opens YouTube with the subscribe confirmation already showing rather than dropping somebody on your channel page to work it out themselves.
Hardly anyone uses it, which is a shame. It costs nothing and it removes the one moment where a willing viewer has to go hunting for a button.
Where it earns its place
| Surface | Why it works there |
|---|---|
| Podcast video corner | The audience is already watching a screen with their phone in reach |
| Conference slides | A room full of people who just decided they liked you |
| Business cards and merch | The card survives the conversation, and the name usually does not |
| Posters and market stalls | The only realistic route from a physical space to a subscription |
The download is a high-resolution PNG, so it stays sharp at print size rather than turning into a soft square on a poster.
The rule that decides whether anyone scans it
Give it room and give it a reason. A QR code in a corner with no label gets ignored, because scanning something takes a small act of trust and nobody spends that on an unlabelled square.
One short line next to it does the work, and that line should name what they get. "Weekly videos on X" beats "subscribe" because it offers something, where the bare instruction only asks.
Where it does not belong
On screen during a video that people are watching on a television or a phone. A viewer holding the phone the video is playing on cannot scan the code with it, and a television is across the room.
For on-screen subscribe prompts inside a video, the end screen and the spoken ask are still the tools. The QR code is for the moments when the audience is looking at something that is not their own phone.
It sits slightly outside the 47
There is no QR code step, because the checklist covers getting a video shipped and this is a channel-level asset you make once. Generate it, put it in the folder with your logo, and use it for years.

The in-video version of this job belongs to end screens and cards, and the ask itself is covered in the call to action guide. If the goal is moving an existing audience somewhere you own, the newsletter guide is the stronger play.
