How does the YouTube Shorts algorithm work? What YouTube says, and what it does not
By Rakshit · Updated
YouTube does not publish a Shorts ranking formula. Its help pages say the Shorts feed is personalised to what each viewer is likely to want next, using signals such as what they watch, what they do not watch, searches, likes, dislikes and survey answers. This page lists what YouTube states, what it does not, and what to do with that.
Read this first: what this page is based on
Many articles on the YouTube Shorts algorithm mix three things: what YouTube has said, what someone measured on their own channel, and what someone guessed. This page sticks to the first. Every statement about YouTube below comes from YouTube's own help or "how YouTube works" pages, read on 11 October 2026, and the sources are listed at the bottom. Where a table has a column on what to do, that column is our own judgement, not YouTube's.
That makes the page date-bound. YouTube changes how it counts views and what it shows in Analytics, and it has done so twice recently (see below). If you are reading this long after October 2026, check the linked pages before you rely on any detail.
YouTube also says the recommendation system learns from over 80 billion pieces of information it calls signals. The pages read list the primary signals but not how they are weighted, so posts that claim exact weights are opinion, not YouTube's word.
What YouTube says, and what it means for a clip
| What YouTube's own page says | What it means when you cut a clip |
|---|---|
| The Shorts feed is personalised to reflect what YouTube thinks each viewer wants to see next. | There is no single ranking everyone sees. A clip is shown to viewers the system expects to like it. |
| The system pays attention to what viewers watch, what they do not watch, what they search for, likes and dislikes, and Not interested feedback. Satisfaction surveys help it understand satisfaction, not just watch time. | What viewers do not watch is one of the signals YouTube lists, so a clip people skip gives the system information too. |
| Relative watch time is broadly more important for short videos, and absolute watch time for longer ones. | For a short clip, how much of it people watch matters more than how many minutes it adds up to. Do not pad a clip to make it longer. |
| The system does not promote videos. It finds videos for each viewer, ranked on performance and relevance to that audience, and not every video is eligible to be recommended. | You cannot force a clip into the feed. You can only make the clip worth the viewers it is shown to. |
| Channel views can decline when viewers stop watching most of your videos when they are recommended to them. | Weak clips are not neutral. Post clips you would stand behind. |
| Growth in views across uploads is not correlated with the time between uploads, according to YouTube's own analyses. | YouTube says its analyses found no link between the gap between uploads and growth, so posting on a fixed schedule for its own sake is not backed by that page. |
| Videos made with AI can be recommended as broadly as videos made without it. | By that page, making a video with AI does not limit how widely it can be recommended. |
The recommendation pages also note that viewers control some of this: they can use Not interested, Don't recommend channel (which applies to Shorts), and a Show fewer Shorts setting in a grid on Home.
Folklore versus what YouTube has stated
| Common claim | Status on YouTube's own pages |
|---|---|
| The first 3 seconds decide whether a Short is pushed. | Not found. YouTube defines Engaged views as viewers who stayed past "the initial seconds" and gives no figure. |
| Viewed vs swiped away is a ranking signal. | Not found. A May 2024 Community post introduces it as a metric you can read in Analytics. It does not call it a ranking signal or give a benchmark. |
| Hashtags and tags get Shorts recommended. | Tags are described as not important for recommendations and as mainly helping with common misspellings. Hashtags have rules: up to three from the description show above the title, and more than 60 on a video means all of them are ignored. |
| There is a best time of day to post. | Not found on the pages read. The only related statement is that growth is not correlated with the time between uploads. |
| Replays and loops boost a Short. | Not found. Engaged views exclude loops, and YouTube does not say whether replays raise recommendation. |
| Location, monetisation or AI use changes who sees a video. | YouTube says location settings are not used to inform recommendations, the system does not know which videos are monetising, and AI-made videos can be recommended as broadly. |
One more thing YouTube states that is often missed: it considers the reputation and quality of a channel when deciding how, when and to whom content can be surfaced.
The 2025 and 2026 view-count updates
The biggest change creators noticed was in how a view is counted, which is easy to confuse with an algorithm change. It is not one.
- From 31 March 2025, a Shorts view counts every time a Short starts to play or replays, with no minimum watch time. The earlier measure, where the viewer chose to keep watching, was kept and renamed Engaged views. YouTube says to use Engaged views to compare your Shorts.
- From 24 August 2026, YouTube says views are counted the moment a video starts to play across all formats: Shorts, long-form videos and live streams.
- YouTube says neither change directly changes Partner Program eligibility or earnings, which stay tied to engaged and qualified views. This page does not cover payouts and gives no figures.
The practical result is that a raw view count says less than it used to about whether anyone watched. When you judge a clip, look at Engaged views and the Stayed to watch percentage first. The retention guide shows how to read the rest.
Turning that into clipping decisions
Given only what YouTube states, these are reasonable defaults. They are judgement, not rules.
- Start: put the strongest line first. YouTube measures whether viewers stay past the opening, and it does not tell you how long that opening is. See the first 3 seconds.
- Length: Shorts can be up to 3 minutes. Because relative watch time is described as more important for short videos, choose the length the moment needs, not the longest allowed.
- Captions: none of the pages read name them as a ranking input. Add them for readability, and check the preview in the app.
- Hashtags and tags: add a few that match the content. Do not stuff them, because over-tagging is against policy.
- Volume: YouTube says growth in views is not correlated with the time between uploads. Post clips you would stand behind.
Where KeyMo fits
KeyMo does the cutting part. It takes a long video, scores each moment out of 10, keeps clips scoring 7 or higher and exports up to 15 vertical 1080x1920 clips with captions in one of 12 styles. The score is its own judgement of the moment, not a prediction of how YouTube will treat the clip.
Starter is $12 a month for 300 source minutes, and there is no free plan or trial. For the full flow from a YouTube source, see YouTube to Shorts.
