How the YouTube Algorithm Works, Explained by YouTube's Head of Discovery
YouTube put out a video where its own team explains how the algorithm works. This page pulls out the parts that matter for creators, in plain words, and shows you what to change. You can watch the full video below.
The short version
The YouTube algorithm does not take your video and look for an audience. It starts with one viewer and picks the best videos for that person. So your job is to make a video that a clear group of viewers wants, not to chase one magic number.
Once you get this, most other worries go away. Subscribers are not a test group. A slow first hour is not a final score. Long videos do well because people watch them on TV. And the same video can be right for one person and wrong for the next. The rest of this page shows how YouTube explains each of these.
How YouTube picks a video for you
When someone opens YouTube, the app looks at what they watch, the time of day, and the device they are on. Then it picks videos for that person. YouTube calls this pulling, not pushing.
“Most of the recommendations are more pulled for each viewer. When a viewer opens their app or turns on their TV, that's when the recommendation system is activated for that viewer.”
Every viewer gets a different set of videos. YouTube does not look at your video and ask who should see it. It looks at each viewer and asks which videos are best for them.
“Each viewer gets a different ranking for each video. We're not looking at a video and saying, let's go figure out who the audience is going to be. It's looking at each viewer and saying, what are the best videos for this viewer at this moment.”
This is why a video with great numbers can still be a bad match for you, and a video with weak numbers can be a great match. It depends on the person watching.
What YouTube is trying to do
There is no single number YouTube chases. Its goal is that people feel their time was well spent and come back tomorrow.
“We'd like them to feel like YouTube delivers the most value, and that that sustains over years. That's what our North Star is: long-term user value.”
To do that, it looks at many signals together, because each one alone is misleading.
“We have to look at many different metrics, because no metric on its own is a good indicator of value. You could look at views, click-through rate, and that will only show you maybe how attractive the thumbnail and the idea were.”
The page on which YouTube metric matters most lists every signal and explains how to read your own analytics. The short version: compare each video with your own past videos, and read your comments.

A few numbers worth knowing
YouTube shared some real figures in the video. These are the ones worth remembering.
- Under 10% of subscribers click a video in their subscriptions feed, even your best videos. So nine in ten fans skip a given upload, and that is normal.
- YouTube may show the same video up to eight times to one person, because people often click after a few tries.
- One viewer saw a channel's uploads 19 times without clicking, simply because they follow about 50 channels and ran out of time.
- Billions of views flow through YouTube every day, which is why the first hour of a video decides nothing.
- Hundreds of experiments run at once, so a home page change you notice may just be a test.
What to do with this
YouTube's advice is simple: focus on your viewers, not the algorithm. Here is how to put that into practice.
- Check what viewers already want before you film. When a small channel gets ten times its normal views on a video, that is real demand you can see. OutlierKit (the tool I build) finds those videos in your niche. The guide to finding outlier videos shows how.
- Make videos for three kinds of viewer. Your biggest fans, your casual viewers, and people who have never seen you. Our content strategy template has a spot for who each video is for.
- Compare each video with your own past videos, not with someone else's. The analytics guide covers the reports to look at.
- Leave notifications and comments on. Turning them off does not protect a video. It only loses viewers.
- Wait weeks before you judge a video. Many videos earn most of their views a month or more after upload.
Frequently asked questions
Does YouTube push videos to viewers?+
No. YouTube builds a feed for each viewer when they open the app or turn on the TV. It looks at what that person watches and picks videos for them. It does not take your video and push it to a crowd. The only thing YouTube pushes is notifications, and only to people who turned them on.
What is the one metric the YouTube algorithm cares about most?+
There is no single one. YouTube says no metric on its own tells it whether a video is good. It looks at click-through rate, watch time, likes, dislikes, comments, and viewer surveys together, and it weighs them differently for different people and devices.
Does the algorithm put my channel in one topic box?+
No. YouTube looks at each video, not the whole channel. It learns which viewers like which of your videos. One viewer might only ever see your Shorts, while another only sees your long videos, based on what each one watches.
Does a slow first hour mean my video failed?+
No. YouTube keeps showing a video to new viewers for weeks. Many videos get most of their views a month or more after upload. The first hour mostly shows your regular viewers, not the full audience the video can reach.
Who explained this?+
Todd Beaupré, who leads YouTube's recommendation team, in a video on YouTube's official Creator Insider channel. It is embedded near the top of this page, and every quote links to the moment he says it.
The rest of what YouTube said
The interview covered eight common creator questions. Each page takes one question, quotes the answer with timestamps, and explains what it means for your channel.
- Does YouTube test my video on subscribers first?
No. It learns from each audience separately, and under 10% of subscribers click even your best video.
- Does a slow first hour kill my video?
No. YouTube keeps testing a video for weeks, and may show it to one viewer up to eight times.
- Which YouTube metric matters most?
No single one. The weights differ by viewer and device. Compare your numbers with your own videos.
- Does YouTube favor longer videos?
No. TV viewers choose them. Bigger thumbnails and fewer options increased long-form viewing.
- Second channel or same channel?
Align channels with audiences and treat each as a brand. YouTube can adjust if you choose wrong.
- Why does YouTube suggest my video next to unrelated ones?
Because one viewer watched both. The watch page is where most subscribers find your videos.
- How does YouTube recommend a brand-new channel?
By matching the topic to viewers instead of using history. If the first viewers do not watch, impressions stop.
